- Minimal business disruption — we work around your schedule
Why Commercial EV Charging Is a Different Problem Entirely
A single home charger is a straightforward install. A carpark with eight charging bays serving a mixed fleet of vans, utes, and passenger vehicles is a different engineering challenge. The core issue is demand: run multiple 7kW or 22kW chargers simultaneously and you can hit the limit of your existing main switchboard fast. Without proper load management, that means tripped breakers, costly network tariff upgrades, or both.
Most commercial and light-industrial premises in the Sutherland Shire — from Caringbah business parks to Sutherland warehouse precincts — were built well before EV charging was a consideration. The metering, sub-board capacity, and cable runs often need assessment before a single charger goes in. Skipping that step leads to expensive retrofits later.
The charging hardware itself matters as much as the wiring. Commercial sites typically require Type 2 AC chargers rated between 7kW and 22kW per bay, with OCPP-compliant units that can communicate with a central management system. That lets you track energy use per vehicle, set access permissions, and bill individual drivers or departments — functions that a domestic unit simply doesn't offer.
Fleet operators also need to think about overnight charging windows versus daytime top-ups, how many vehicles actually need a full charge each night versus a partial charge, and whether your electricity tariff makes off-peak scheduling worthwhile. We work through all of this before any cable is run.
How Voltie Designs a Commercial Charging System
We start with a site assessment — not a quote form. That means physically reviewing your switchboard capacity, cable routes, carpark layout, and available network supply. For larger installations, we coordinate with Ausgrid or Endeavour Energy on supply upgrades if your existing connection can't support the projected load. From there we produce a charging layout that matches your actual fleet rotation, not a generic template.
- Site electrical audit: switchboard rating, available capacity, tariff structure
- Load management design using dynamic load balancing to maximise bay count without network upgrades
- Hardware selection: OCPP-compatible units, access control, energy monitoring
- Conduit and cable installation per AS/NZS 3000 wiring rules
- Commissioning, testing, and handover with management software setup
- Ongoing support if chargers need firmware updates or fault diagnosis
