No, a solar-only system will shut down automatically during a power cut. However, all the systems we now install as part of our solarZero energy service include a battery and hybrid inverter. This means the panels can continue to generate electricity during a power cut. That electricity will power selected circuits in your home and charge the battery.

The main parts include the roof-mounted solar panels, the hybrid inverter, battery, isolators and energy management computer which are housed in a single cabinet, and the electrical sub board. There are also railings for attaching the panels to your roof and cabling that runs from the panels to the inverter and to your switchboard.

Inverter – changes the energy produced by the panels and stored in the battery in to usable AC power

DC and AC isolators – Isolate the flow of current at the point of the isolator

Battery – Stores energy

You may export to the grid if our system installed as part of the solarZero energy service generates more electricity than it can use and store. This will depend on the size of the system as well as the daily use of electricity in your home. You may generate surplus solar in the summer months as system sizing is based on average annual power usage, not for summer peaks. We will work closely with you to ensure that our whole system is working in the most effective way. One of the benefits of the solarZero service is the solar export credit that ensures that when you sell solar power you’re paid the same rate it costs you to buy energy, excluding network charges and GST.
