Commercial EV Charging
Commercial EV charging infrastructure designed around your operations - not bolted on as an afterthought.
The future is electric
Your business runs on vehicles. Whether that's a service fleet returning to base each evening, staff parking at a commercial premises, or a site that needs to manage a growing mix of electric and hybrid vehicles, the infrastructure underneath it all has to be right from day one.
Off The Grid designs and installs commercial EV charging systems that work with your energy setup, your grid connection and your operational schedule - not against them.
Get it right & reap the rewards
Fuel costs are rising and fleet electrification is a current consideration, not a future one.
The businesses that struggle aren't the ones who moved too fast - they're the ones who installed basic chargers without thinking about capacity, solar integration or future fleet growth. The result is unbudgeted grid upgrades, chargers that can't talk to fleet management software, and energy costs that don't improve because nothing is managing when and how vehicles charge.
A properly engineered system does the opposite - reducing operating costs, using solar generation intelligently, and growing with you without expensive do-overs.
What we deliver
From workplace charging to full fleet depot infrastructure, here's how we help Australian businesses transition to electric - efficiently and cost-effectively.
Staff and Visitor Charging at the Workplace
Reliable, access-controlled EV charging that works for employees, visitors and the finance team responsible for cost allocation:
- RFID authentication restricts access to authorised users and tracks individual charging sessions for reimbursement or cost-splitting
- OCPP 1.6/2.0 compliance connects your chargers to backend management platforms, giving you usage data, billing records and remote control
- Dynamic load balancing prevents EV charging from overloading your existing supply, protecting your switchboard capacity and avoiding demand charge spikes
- Solar linkage draws from your rooftop generation first, reducing the per-charge cost during business hours
Hardware suited to this application includes the FoxESS A Series (7.3 kW single-phase through to 22 kW three-phase, socket and tethered options, - Bluetooth/Wi-Fi/LAN/4G) and the Wallbox Copper SB (IP54/IK10-rated, myWallbox CPO platform, automated payments for semi-public use)
Your staff charge their vehicles at work, your finance team has clean records, and your site's solar investment is doing more than it was yesterday.
Fleet Depot Charging - Keeping Vehicles Mission-Ready
High-throughput charging that gets your fleet back on the road every morning without straining your grid connection:
- Dual-gun chargers serve two vehicles simultaneously from a single unit, improving turnaround at depots where space and connection points are limited
- Dynamic load management distributes available power across active chargers based on departure schedules, so the vehicles that need to leave first get priority
- OCPP integration connects to fleet management platforms for charge scheduling, state-of-charge monitoring and remote session control
- Robust, depot-grade hardware handles the demands of daily commercial use without maintenance headaches
- The FoxESS C Series (dual-gun AC, 7.3 to 22 kW per outlet, IP55/IK10, Ethernet/4G, full OCPP) and the Delta AC Max Smart (OCPP 1.6J upgradable to 2.0, RFID, cellular, ISO 15118, IK09-IK10) are well suited to this application
Your vehicles leave fully charged each morning, your grid connection stays within its existing limits, and your operations team has the data they need to manage the fleet.
Solar-Integrated Commercial Charging - Cutting the Cost of Every Charge
Running your charging load predominantly on self-generated solar power rather than grid electricity changes the economics of fleet electrification significantly:
- On-site solar generation is prioritised for EV charging during business hours, reducing grid imports at the times when tariffs are highest
- Battery storage captures surplus generation for evening and overnight charging, extending solar self-consumption beyond daylight hours
- Demand management controls discharge to avoid peak tariff windows, reducing both energy and demand charges on your bill
- Integrated energy platforms (GoodWe SEMS/SEMS+ with the HCA G2 charger series, or the SigenStor commercial system with its integrated 25 kW DC fast-charge module) coordinate solar, storage and EV charging as a single managed system
- Commercial battery options including the GoodWe Lynx C/BAT-C, AlphaESS Storion series and SAJ CHS2 provide the storage capacity to make this work at scale
The energy cost of charging your fleet drops materially, your solar investment earns its return faster, and your exposure to grid tariff volatility is reduced.
Scalable Infrastructure for Growing Operations
Starting with six chargers and planning for twenty is the right way to approach commercial EV infrastructure - if the system is designed for it from the start:
- OCPP-enabled hardware integrates with enterprise charge management platforms, making it straightforward to add users, sites and vehicles without replacing equipment
- Load management software keeps your existing grid connection viable as charging demand increases, deferring or eliminating the cost of a capacity upgrade
- Modular charger architectures (Wallbox Commander 2 with its advanced load balancing and multi-unit power sharing, or the Delta AC Max Smart with adjustable output and full OCPP) are designed to be expanded without expensive rewiring
- Site infrastructure is designed with future conduit runs, switchboard capacity and metering already accounted for
You start with what you need today and scale to what you need tomorrow - without tearing out what you've already installed.
Only the best brands.
A commercial EV charging company you can count on
We design for operations, not just for installation day
Most EV charger installers focus on getting hardware on the wall and the job signed off. We focus on how your charging infrastructure performs six months and three years from now - under real load, with real fleet growth, and integrated with your solar and battery systems. That means fewer surprises and a system that keeps delivering.
One partner across your entire energy system
Off The Grid installs and supports solar, batteries and EV charging as a coordinated system, not as separate products from separate suppliers. That matters when you want your chargers drawing from solar first, or when your battery storage needs to be managed alongside your fleet charging schedule. You're not dealing with three different providers pointing fingers at each other.
Commercial-grade hardware, correctly specified
We work with commercial-appropriate products - OCPP-compliant, RFID-enabled, load-management-capable hardware from FoxESS, Wallbox, Delta and GoodWe - and we specify the right product for each application rather than defaulting to whatever's easiest to install. A depot has different requirements from a workplace carpark, and we treat them differently.
Local support that doesn't disappear
After installation, you have direct access to local technicians who know your system, not an overseas support queue. We monitor performance proactively and respond to faults before they become operational problems. Your vehicles need to be charged and ready every day - our support is built around that reality.
What's the Process?
1.
Site Assessment
We assess your site's existing electrical infrastructure & capacity, solar generation, parking layout & fleet profile. You get a clear picture of what's feasible, what changes are needed and what the system will cost to build and operate.
2.
Infrastructure & System Design
We design the full charging infrastructure: charger quantity, power levels, load management configuration, solar and battery integration, switchboard requirements & future capacity.
3.
Installation & Compliance
Electricians install the system to AS/NZS standards. All electrical work is certified, grid connection is coordinated, and hardware is commissioned and tested before handover.
4.
Platform Setup & Ongoing Support
We configure your charge management platform - OCPP backend connection, RFID user setup, load management parameters and reporting. After handover, remote monitoring continues and our local team responds to any issues.

Your Questions, Answered
How many chargers does my site need and how do I size the infrastructure?
The right number of chargers depends on your fleet size, dwell time and whether vehicles charge overnight or during business hours. We start with a load analysis to understand your peak demand and map that against your grid connection capacity. In most cases, smart load management means you can charge more vehicles than the raw numbers suggest, without upgrading your connection.
Can commercial EV charging integrate with our existing solar system?
Yes, and it's one of the most effective ways to reduce the per-charge cost. If your site has existing solar, we configure your chargers to draw from generation first. If you're installing solar and charging together, we design them as an integrated system from the outset. GoodWe's SEMS+ platform and the SigenStor commercial system with its integrated DC charger are examples of how solar, storage and EV charging can be managed as a single coordinated setup.
What is OCPP and do we need it?
OCPP (Open Charge Point Protocol) is the industry standard that allows your chargers to communicate with backend management platforms - for usage reporting, RFID access control, cost allocation, scheduled charging and integration with fleet management software. For workplace charging with more than a handful of chargers, or any site with shared or visitor charging, OCPP capability is important. All the commercial hardware we install - FoxESS A and C Series, Wallbox Copper SB and Commander 2, Delta AC Max Smart - supports OCPP 1.6 and 2.0.
What does ongoing support look like after installation?
We monitor system performance remotely and contact you if we detect a fault before it affects operations. For OCPP-connected systems, we can push firmware updates and adjust configuration remotely. If a site visit is needed, our local technicians respond directly - not through a national call centre. We also provide support as your fleet grows, advising on capacity additions and platform changes as your needs evolve.
