Cost Depth: What Drives Load Management Pricing in NSW
EV charger load management cost is driven by the number of chargers being managed, the communications protocol required, and the degree of integration with site energy systems. A basic current limiter on a single residential charger is a passive device costing $300 to $700 that simply caps the charger's maximum current draw to prevent nuisance tripping. A dynamic system for two residential chargers that communicates between the units in real time to share available capacity costs $800 to $2,000 for the additional management hardware and configuration. Commercial and strata systems require OCPP-compatible chargers, a back-end management platform, and network infrastructure at the site, pushing costs to $2,000 to $15,000 depending on scale. For strata properties the additional complexity of individual unit metering, billing management, and getting body corporate sign-off adds cost and project management time beyond what a purely residential or commercial site requires.
Load management installation requires a licensed electrician. Verify licences through NSW Fair Trading. For strata properties, confirm body corporate approval under the NSW Civil and Administrative Tribunal framework before commencing work.
EV Charger Load Management in NSW for 2026
Load management is the technical discipline of distributing available electrical capacity across multiple EV chargers in a way that prevents supply overload, minimises grid demand charges, and maximises the use of on-site renewable generation. Without load management, adding a second or third EV charger to a residential or commercial property risks tripping the main service fuse during periods when multiple vehicles charge simultaneously, or triggering expensive commercial demand tariff penalties when all chargers operate at full rated power at the same time. Load management solves this by treating the site's available electrical capacity as a shared resource that is dynamically allocated between chargers based on real-time demand, priority settings, and energy management rules.
NSW's EV adoption rate has accelerated substantially since 2022, and a growing proportion of NSW households now have two EVs sharing a single residential switchboard that was sized for one charger. Commercial and business properties are similarly facing the challenge of serving increasing numbers of EV-driving staff, customers, and fleet vehicles from electrical infrastructure that was not designed with high-density EV charging in mind. Load management technology has advanced in parallel with this demand growth, moving from simple current-capping devices to sophisticated OCPP-networked systems that integrate with site energy management platforms, feed-in tariff monitoring, and solar battery dispatch.
Why Load Management Matters in NSW
NSW residential service connections are typically rated at 63 amps single-phase (approximately 14.5kW) or 3 x 63 amps three-phase (approximately 43.5kW). A household with two 7.4kW single-phase EV chargers running simultaneously draws 14.8kW from the chargers alone, which exceeds the capacity of a standard single-phase service and leaves no headroom for any other household load. Even on a three-phase service, running two 7.4kW single-phase chargers on the same phase creates a 14.8kW single-phase demand that exceeds the per-phase limit. Without load management, the only alternative to nuisance tripping is an expensive service upgrade to a higher-rated fuse, which costs $500 to $2,000 in addition to any DNSP contribution for network works.
For commercial properties on demand tariffs, the financial stakes of unmanaged EV charging are higher still. NSW commercial electricity tariffs from retailers including AGL, Origin, EnergyAustralia, and smaller retailers typically include a demand charge component based on the highest 30-minute peak demand recorded in the billing period, rated at $5 to $20 per kilowatt-month. A business with 10 employees all plugging in EVs simultaneously at 9am creates a demand spike of 74kW at 7.4kW per vehicle that triggers demand charges of $370 to $1,480 per month on top of consumption charges. A load management system that spreads the same 74kWh of daily charging over 8 hours at a maximum instantaneous demand of 22kW reduces the demand charge by 70 percent, saving $260 to $1,030 per month in demand charges alone.
Residential Two-EV Load Management
The most common residential load management scenario in NSW is two EVs sharing a switchboard that was originally sized for one dedicated EV charger circuit. The simplest solution is a paired load management system supplied by a single charger brand, where both charger units communicate with each other over a proprietary or Wi-Fi link and share the available circuit capacity dynamically. myenergi's ecosystem allows two Zappi chargers to share a single CT clamp monitor and coordinate their combined draw. Wallbox offers paired management through their Power Boost feature, where a current meter installed at the switchboard feeds real-time data to both chargers, enabling them to self-regulate their combined demand below a configured maximum. EVNEX similarly supports multi-unit load sharing within their product ecosystem.
The installed cost for a two-charger dynamic load management setup on a residential property ranges from $800 to $2,000 depending on whether both charger units are new or one is being added to an existing installation, and whether new cabling is required for the second charger circuit. For properties where adding a second independent 32-amp circuit would exceed switchboard capacity, the load management approach is not just cost-effective but necessary, providing a compliant two-EV charging solution without a switchboard upgrade. The trade-off is that on nights when both vehicles need a full charge simultaneously, each charger operates at reduced power compared to its rated output, extending charge time. In practice, most households find the flexibility of adjustable priority settings adequate for their specific pattern of vehicle arrivals and departure times.
A practical tip almost no installer volunteers: if you have a BYD Atto 3 and a Hyundai Ioniq 6 on the same load-managed system, configure the Ioniq 6 as Priority 1. The Atto 3 accepts 7.4kW maximum and is completely indifferent to whether it gets 3.7kW or 7.4kW - it will fill in the same overnight window either way. The Ioniq 6 accepts 11kW and its onboard charger is less tolerant of fluctuating power inputs; giving it priority means it gets a stable charge rate while the Atto 3 takes whatever headroom remains. Failing to set priority correctly is the single most common reason two-EV households report that the system "doesn't seem to work properly."
OCPP Protocols Explained
The Open Charge Point Protocol (OCPP) is an open standard that defines how EV chargers communicate with a central management system, enabling charger monitoring, remote configuration, user authentication, and load management commands across chargers from different manufacturers. OCPP 1.6 is the most widely deployed version in Australian commercial installations and supports the core functions of remote start and stop, real-time status monitoring, user authentication via RFID card, and basic smart charging profiles that allow the management system to set a maximum charge current per charger in response to grid or site conditions.
OCPP 2.0.1 represents a significant upgrade over 1.6, adding ISO 15118 Plug and Charge support (where the vehicle authenticates automatically without a separate RFID card), bidirectional charging (V2G) capability, enhanced security, and more sophisticated smart charging profiles that allow finer-grained load management commands. OCPP 2.0.1 is the target standard for new commercial installations in NSW where future V2G capability or advanced demand response participation is part of the site's energy strategy. Not all charger hardware available in NSW in 2026 supports the full OCPP 2.0.1 feature set, so confirming which OCPP version and feature profile a specific charger implements is important when specifying a new system.
A complete OCPP-based load management deployment for a commercial site requires three components beyond the charger hardware itself: a charge point management system (CPMS) back-end that receives data from all chargers, a local controller or gateway at the site that manages communication between the chargers and the CPMS, and network connectivity (typically 4G or fixed broadband) from the site to the CPMS. Subscription fees for commercial CPMS platforms run $10 to $50 per charger per month. For smaller commercial deployments of 3 to 10 chargers, locally hosted CPMS options using open-source platforms can reduce ongoing subscription costs, though they require more technical expertise to deploy and maintain.
Commercial Demand Charge Mitigation
Demand charge management is the primary financial justification for load management systems in commercial NSW properties. The standard approach is to configure a maximum site demand threshold in the load management system, typically set at 10 to 20 percent below the site's recorded peak demand from non-EV loads, and allow the load management system to distribute available capacity above this threshold across all active EV chargers. When the building's base load is low, more capacity is available for EV charging; when the building load is high (air conditioning peak in summer, production equipment running), the load management system automatically reduces EV charger outputs to keep the total site demand below the threshold.
Integrating the load management system with the building's energy management system (BMS) or with real-time smart meter data from the DNSP provides the most accurate demand control, because the load management system can see the actual building consumption in real time rather than relying on a static threshold. DALI, Modbus, and BACnet interfaces are the most common integration protocols for connecting EV load management systems to existing BMS platforms. For properties that do not have an existing BMS, a dedicated site controller with a CT clamp measuring total site demand at the main switch provides equivalent real-time input to the load management system at lower cost than a full BMS integration.
Here is a real-world demand charge calculation NSW businesses often find eye-opening. AGL's business demand tariffs in Sydney price network demand at roughly $12 to $18 per kW per month depending on the tariff class. An office building in Parramatta with six unmanaged 7.4kW chargers all activating at 9am creates a 44kW spike that adds $528 to $792 to the monthly bill permanently - even if it only happens once that billing period. A load management system capping the combined output at 15kW adds $180 to $270 per month and pays for the hardware in under 24 months purely from demand charge reduction. Pulling 12 months of interval meter data from your retailer before commissioning a load management system allows you to set the demand cap threshold accurately rather than guessing.
Solar and Battery Integration
Load management systems that integrate with on-site solar generation and battery storage enable a third level of optimisation beyond simple demand capping: directing solar surplus to EV charging during peak generation hours and dispatching battery energy to EV chargers during periods when grid electricity is expensive. This combined approach, sometimes called smart energy management or vehicle energy management, is the most sophisticated residential and commercial EV charging configuration available in NSW and delivers the greatest financial return per kilowatt-hour of vehicle charging demand.
For residential applications, the myenergi ecosystem (Zappi charger, eddi hot water diverter, libbi battery) provides an out-of-the-box multi-device energy management capability that coordinates solar surplus allocation across all connected loads. SolarEdge's home energy management platform integrates the SolarEdge EV charger with SolarEdge battery and inverter products, providing comparable functionality within the SolarEdge ecosystem. Alpha ESS batteries with their EMS integration support third-party EV charger coordination via API, and GivEnergy batteries offer similar capabilities. For commercial applications, dedicated energy management platforms from companies such as Schneider Electric EcoStruxure, Siemens Energy Manager, and Charge HQ provide the software layer to coordinate solar, battery, and EV charging assets across a site or multiple sites.
Strata and Apartment Applications
Strata residential properties in NSW present the most complex load management challenge because EV charging demand must be shared across the strata's common supply point or individual lot supply connections, the charging costs must be accurately metered and allocated to individual lots, and the body corporate must approve the infrastructure before any installation proceeds. The preferred technical architecture for strata EV charging in NSW uses a sub-metered charging point for each participating lot, connected to either the lot's own supply (if the switchboard is accessible and has capacity) or a dedicated strata EV charging supply point in the carpark. A central OCPP management system handles usage tracking, billing data export for individual lot invoicing, and dynamic load sharing across all active chargers to stay within the strata's available supply capacity.
For complete detail on strata EV charger installation in NSW, including body corporate approval processes, metering and billing approaches, see the strata EV charger installation NSW guide.
Load Management Brands in NSW - What Actually Works
myenergi's ecosystem provides the most accessible residential load management solution in NSW, with the Zappi charger's built-in CT clamp monitoring enabling two or more Zappi units to coordinate their demand without requiring a separate controller device. EVNEX offers multi-unit load management within their platform, and Wallbox's Power Boost system performs similar dynamic sharing for residential and small commercial applications. For commercial OCPP-based systems, ABB Terra AC, Schneider Electric EVlink Pro, and EVNEX E3 all offer charger hardware with OCPP 1.6 support. Tritium (an Australian company) and ChargePoint have products supporting OCPP 2.0.1 for larger commercial deployments. Charge HQ is an Australian software company that provides a vehicle-side smart charging platform compatible with multiple charger brands, offering a software-only load management layer that works with existing hardware.
Some practical notes on what NSW installers have found in the field: the Wallbox Power Boost works reliably when both Wallbox chargers are on the same Wi-Fi network and within good signal range of each other. When one charger is in a garage at the front of a property and the other is at a rear carport 20 metres away through a double-brick wall, the Wi-Fi link drops and both chargers revert to their default maximum draw - the exact problem load management is supposed to prevent. Running a CAT6 cable between the two charger locations and using a wired connection instead of Wi-Fi eliminates this failure mode entirely. Ask your installer whether they plan to use Wi-Fi or a wired link and why, particularly on properties where the two charger locations are not in the same room.
NSW Grid Connection Implications
Large commercial EV charging installations in NSW that exceed certain demand thresholds require formal DNSP network connection applications. Ausgrid's and Endeavour Energy's published connection processes specify the thresholds above which a formal connection application is required, and these vary by connection voltage level and the type of load being connected. A business adding 10 x 22kW chargers creates a potential additional demand of 220kW, which will require a formal application, load flow assessment, and potentially network augmentation contribution before the chargers can be energised. The connection process for large commercial EV charging sites can take 3 to 12 months from application to approval depending on the network operator and the complexity of the required network works.
Load management systems that credibly reduce the peak demand profile presented to the network can positively influence the DNSP's assessment of network augmentation requirements, because the managed peak demand is lower than the theoretical maximum demand of all chargers running simultaneously. A formal demand management plan submitted with the connection application, demonstrating how the load management system will limit peak demand, has in some NSW cases resulted in reduced or waived network augmentation contributions. The NSW Department of Energy website covers EV infrastructure funding programs and the connection process for large commercial charging sites.
Sydney Metro Load Management Pricing
Sydney metropolitan load management installation pricing follows the general pattern of EV charger installation costs, with western and south-western suburbs being the most competitive zone and inner city and eastern areas attracting premiums for access and infrastructure complexity. A two-charger dynamic load management setup for a residential property in western Sydney costs $800 to $1,500 including the management hardware, configuration, and CCEW. An OCPP-based commercial system for a 6-charger site in the Sydney CBD costs $3,500 to $6,000 for installation, configuration, and first-year CPMS subscription. Commercial sites in outer western and south-western Sydney run 15 to 25 percent less than equivalent inner city work, reflecting both lower electrician rates and easier site access.
| Sydney Region | Residential 2-EV | Commercial 6-Charger OCPP | Notes |
|---|---|---|---|
| Inner Sydney / CBD | $1,100-$2,200 | $4,500-$8,000 | Access premium, older infra |
| North Shore / Northern Beaches | $950-$1,800 | $3,800-$6,500 | Varied site conditions |
| Western Sydney | $800-$1,500 | $3,000-$5,500 | Most competitive |
| South-Western Sydney | $800-$1,500 | $3,000-$5,500 | New estates, modern infra |
| Wollongong / Illawarra | $850-$1,600 | $3,200-$5,800 | Competitive market |
Regional NSW Load Management Pricing
Regional NSW load management pricing tracks the same travel and market structure as other EV charger work. Newcastle and the Hunter Valley are competitive and well-serviced. Byron Bay and the Northern Rivers attract 15 to 25 percent above Sydney western benchmarks for equivalent scope. Inland regional centres run 10 to 15 percent above Sydney benchmarks with modest travel premiums. For commercial sites in regional NSW, the limited pool of electricians with OCPP system commissioning experience means some projects require specialists to travel from Newcastle or Sydney, adding travel cost that can be offset by packaging multiple sites or services in a single visit.
What to Look For in Load Management Quotes
A load management quote should specify the management approach (passive limiter, dynamic sharing, OCPP-networked), the specific hardware model and firmware version, the OCPP version supported if applicable, and whether a CPMS platform subscription is included in the quote or is an ongoing cost payable separately. For commercial systems, the quote should identify who is responsible for CPMS configuration, ongoing system monitoring, and firmware updates, as these responsibilities vary between installation-only contracts and managed service agreements. OCPP system commissioning requires testing the communication link between each charger and the CPMS, configuring load management profiles, and verifying demand-capping behaviour under simulated load conditions before the system goes live.
Confirm the electrician holds an NSW electrical contractor licence (check it at NSW Fair Trading) and that a CCEW will be issued for all electrical work. For commercial systems with a cloud software component, ask where the data is hosted and who owns it if the software company closes or is acquired - this has caught several Australian businesses out with early OCPP platforms. The ACCC provides guidance on commercial warranty rights if hardware fails early. Post your load management project on The Quote Yard to connect with NSW electricians experienced in residential, commercial, and strata EV charging installations. All electrical work involved in load management installations - circuit additions, CT clamp installation, switchboard modifications - must be carried out by a licensed electrician under AS/NZS 3000:2018, with a CCEW issued on completion.
Common Load Management Implementation Issues
The most frequent issue in residential load management installations is undersized communication infrastructure between the paired chargers. Dynamic load sharing between two charger units requires reliable real-time communication, and installations where the chargers are at opposite ends of a building with thick concrete or steel walls between them sometimes experience communication dropouts that cause the chargers to revert to their default maximum draw rather than their managed shared rate. Confirming Wi-Fi signal strength or running a dedicated communication cable between the charger locations before finalising the installation design avoids this problem. For commercial OCPP systems, the equivalent issue is CPMS connectivity: a site with unreliable broadband or 4G signal requires a backup connection strategy to ensure the management system can communicate with chargers continuously.
Load profile misconfiguration is another common commercial issue, where the demand cap threshold is set too conservatively, causing EV chargers to operate at very low outputs even when the building load is well below the service limit. This results in dissatisfied users who find their vehicle barely charged after a full day of work. Correct configuration requires a detailed understanding of the site's actual load profile across different times of day and seasons, and ideally a review of 12 months of interval meter data from the DNSP to establish the baseline demand profile before setting the EV charging headroom parameters. The EV charger solar integration NSW guide and the EV charger installation cost NSW guide provide context for load management as part of a complete EV charging strategy.
The Questions to Ask Before You Choose a Load Management System
For residential two-EV setups, the practical questions are: will both chargers communicate reliably from their respective locations (Wi-Fi or wired?), can you set which vehicle gets priority and change it easily from an app, and what happens to both chargers if the internet goes down - do they default to full draw, zero draw, or maintain the last set limit? The last question matters more than most people think. A charger that reverts to full draw when offline is fine for a low-capacity switchboard. A charger that reverts to zero draw means your car sits uncharged if the NBN drops at 11pm.
For commercial installations, the questions shift: what is the ongoing subscription cost per charger per month for the cloud management platform, who is responsible for firmware updates and what happens to the system if the software company shuts down, and can the system export energy usage data in a format your accounting software can read for tenant billing? The last point trips up a lot of commercial operators who discover after installation that the charger's reporting portal exports in a proprietary format that requires manual re-entry into their billing system. Ask for a sample data export before you sign anything. Verify the installer's licence at NSW Fair Trading and check ACCC guidance on warranty rights via the ACCC. For the full picture on EV charging system costs, the EV charger installation cost NSW guide covers pricing across all charger types.
What Your Energy Bill Looks Like After a Well-Configured Load Management System
The clearest way to understand what load management actually delivers financially is to look at the bill components before and after. Before: your demand charge is based on the highest 30-minute average demand recorded that month, including any peak where all EVs started charging simultaneously with the building load running high. After: the load management system caps the EV contribution to whatever headroom you configure, so the demand peak from EV charging is eliminated entirely. On AGL's standard business demand tariff in Sydney, shaving 20kW off your monthly peak demand saves $240 to $360 per month - that is $2,880 to $4,320 per year on a system that might cost $3,000 to $8,000 to install. The payback is under two years for most commercial sites where unmanaged EV charging was creating regular demand spikes. The solar monitoring NSW guide covers how combining solar monitoring with load management improves these savings further.
Getting Started with Load Management in NSW
The fastest path to a correctly specified and commissioned load management system in NSW is engaging an installer who has completed comparable projects and can demonstrate working systems rather than theoretical capability. Request a site visit before accepting any quote for a commercial or strata system, confirm the OCPP platform's Australian hosting and support arrangements, and ask for a commissioning test report as a project deliverable. Post your load management project on The Quote Yard to connect with NSW electricians and system integrators who have demonstrable experience across residential, commercial, and strata EV charging infrastructure deployments.
The One Question Most NSW Businesses Forget to Ask
The question almost no one asks before signing a commercial load management contract: what happens to the system if the software company gets acquired or shuts down? This is not a hypothetical - at least two OCPP management platform companies that sold systems into Australia between 2019 and 2022 no longer operate under the same name or on the same platform they originally supplied. Chargers connected to those platforms were left operating in "offline mode," which typically means no load management commands, no usage reporting, and no remote diagnostics until the operator pays someone to migrate to a different platform.
The practical protection is to require in the contract that the installer provides the OCPP server credentials and configuration data in a documented format at the time of commissioning, so that if the platform changes, your electrician can reconnect the chargers to an alternative CPMS without starting from scratch. Also ask whether the chargers can operate in a standalone local-control mode without the cloud platform - some chargers have a local load management mode that continues to function even when cloud connectivity is lost, and for critical commercial applications like a hospital or aged care facility, this local fallback capability is worth specifying explicitly. For residential two-EV setups using proprietary brand ecosystems like myenergi or Wallbox, this risk is lower because the management logic runs on the charger hardware itself rather than on a separate cloud platform.

EV Charger Load Management FAQs - NSW
What is EV charger load management?
Load management distributes available electrical capacity across one or more EV chargers to prevent the total demand from exceeding the site's supply limit, avoiding tripped fuses, supply upgrade costs, and commercial demand tariff penalties. At a residential level it allows two EVs to charge simultaneously on a switchboard sized for one charger. At a commercial level it enables dozens of chargers to share a single supply connection by dynamically allocating current based on vehicle charging state and site load conditions.
Do I need load management for two EVs at home in NSW?
Not always, but it is often advisable. If your NSW property has a three-phase supply with sufficient available capacity for two 32-amp circuits, two independent charger circuits may be feasible without load management. If you are on single-phase supply or your switchboard is already near capacity, running two 7.4kW chargers simultaneously can exceed the service fuse rating and cause nuisance tripping. A load management system, or a pair of chargers with built-in dynamic sharing, solves this without requiring a service fuse upgrade. An electrician assessing your switchboard will advise which approach is appropriate for your specific supply capacity.
What is OCPP and why does it matter for commercial EV charging?
OCPP (Open Charge Point Protocol) is an open standard that defines how EV chargers communicate with a central management system for remote monitoring, user authentication, load management, and billing data. It matters for commercial sites because it allows chargers from different manufacturers to be managed through a single platform, and because it enables smart charging features like dynamic load capping, demand response, and eventually vehicle-to-grid operation. OCPP 1.6 covers core commercial functions; OCPP 2.0.1 adds Plug and Charge, bidirectional charging, and enhanced security.
How much can load management save on commercial electricity bills in NSW?
Savings depend on the site's tariff structure. For commercial properties on demand tariffs, reducing the peak demand contribution from EV charging by 70 percent can save $260 to $1,030 per month in demand charges for a 10-charger site, depending on the retailer's demand charge rate. For sites on time-of-use tariffs, scheduling EV charging to off-peak windows reduces consumption charges by 30 to 50 percent per kilowatt-hour of EV energy. For solar-integrated commercial sites, load management that prioritises solar generation for EV charging converts low-value export into high-value self-consumption, adding a further $0.20 to $0.30 per kilowatt-hour of solar EV energy.
Can load management be added to existing EV chargers?
It depends on the charger hardware. Some smart chargers support load management as a firmware feature that can be activated after installation. Others require a separate controller device to be added to the installation. Basic current limiters can be added to any charger circuit at the switchboard level regardless of the charger's capabilities. Full OCPP-based load management requires the chargers to support OCPP, which is a hardware and firmware capability. Older basic wall chargers without network connectivity generally cannot be upgraded to support OCPP and may need to be replaced for a commercial load management deployment.
What approval do strata properties need for EV load management in NSW?
Strata properties in NSW require body corporate approval under the Strata Schemes Management Act 2015 before installing shared EV charging infrastructure. The 2020 amendments to the Act require the body corporate to have reasonable grounds for refusal, and lot owners can apply to the NSW Civil and Administrative Tribunal if consent is unreasonably withheld. For shared infrastructure serving multiple lots, a special resolution at a general meeting may be required. Individual lot owners installing chargers solely within their own lot with no impact on common property have a lower approval threshold. Engaging a strata manager and a qualified electrician experienced in strata EV projects to prepare the approval documentation significantly improves the process.
How is each EV user billed in a shared commercial or strata system?
OCPP-based systems measure the energy delivered to each vehicle at the charger level and report session data (user, energy delivered, duration, cost) to the CPMS back-end. The CPMS generates usage reports that can be used for individual billing, either through the CPMS platform's own billing module or exported to a third-party billing system. For strata properties, session data is typically provided to the strata manager for inclusion in levy calculations or direct lot invoicing. For workplaces, the data supports employee reimbursement claims or payroll deductions. Sub-metered chargers with individual revenue-grade meters provide the highest billing accuracy and are required for commercial public charging applications.
Does load management affect how quickly my EV charges?
Yes, when multiple vehicles are charging simultaneously and the available capacity is being shared. Each charger receives a fraction of the site's total available capacity rather than its full rated output, which means individual charge rates are lower than when a single vehicle charges alone. The practical impact depends on how many vehicles are charging at once relative to the total available capacity. At times when only one vehicle is charging, it receives full available capacity. Well-configured load management with appropriate priority settings (for example, giving higher priority to vehicles departing earliest) minimises the real-world impact on charging adequacy for most users.
Can EV load management integrate with a solar system and battery?
Yes, and this is increasingly the preferred configuration for commercial and advanced residential NSW sites. Load management systems that integrate with solar inverter APIs and battery management systems can allocate solar surplus to EV charging during generation hours, dispatch battery energy to EV chargers during peak tariff periods, and reduce grid import to the minimum necessary. This three-way coordination of solar, battery, and EV charging delivers the maximum financial return per kilowatt-hour consumed and the minimum grid demand, which together reduce electricity costs and demand charges more than any single technology alone.
How long does load management system installation take?
A residential two-EV dynamic load management installation typically takes 3 to 6 hours including charger installation and commissioning. A commercial OCPP system for 4 to 6 chargers typically takes 1 to 2 days for hardware installation plus a half-day for CPMS configuration, testing, and user training. Larger commercial and strata deployments are staged over multiple days or weeks depending on site access constraints and the number of chargers being installed. CPMS configuration and commissioning is often the critical path item, as it requires the hardware to be installed and networked before software configuration can be validated and signed off.
