Single-Phase Home Limiting Your System Size?
Single-phase home limiting your system size is common in older houses. Single-phase supply has tighter inverter and export limits than three-phase supply, and your distributor sets the figures for your address. This page is part of our residential solar panel installation service.

How to Tell Which Supply You Have
Check your switchboard, meter or electricity bill, or ask us during the site assessment.
Sizing a System That Fits
- Design the inverter and panel count to the limit your network offers.
- Use more of your solar power at home to get value from every kilowatt-hour.
- Add a battery to store daytime power for the evening.
Upgrading to Three-Phase
Some homes can upgrade to three-phase supply, which lifts the limits. It needs an electrician and the distributor, and it is not always possible, so we check before we quote.
Network Approval
We lodge the application for you and design to the limit you are offered.
