Overview
If your home keeps tripping, your solar is being limited, or you're adding an EV charger, ducted air or a big renovation, a single-phase supply may no longer be enough.
We assess your load, apply to the network for the upgrade, replace the service with three phase and coordinate the metering so the whole job is handled in one place.
Single phase vs three phase
Most older Sydney homes have a single-phase supply. Three phase brings in three active conductors instead of one, giving far more capacity and allowing large loads like ducted air, EV chargers and big solar and battery systems to be spread evenly.
What the upgrade involves
The network has to approve the increase first. Once approved, the service line or underground cable is replaced with a three-phase service, the consumer mains are upgraded if they're undersized, and the metering is changed to suit. Your switchboard usually needs work too, which we coordinate.
Ausgrid and Endeavour Energy
We're accredited with both networks, so we lodge the application, carry out the Level 2 work and submit the completion paperwork whichever network you're on.
