Battery
Make the sun work to your schedule and don’t let all that solar energy go to waste.
Here's how it works
Adding a battery to your solar system allows you to store the excess solar energy you generated during the day and access it later, when your home needs it. It also ensures you have your own power supply during an outage.
You've got power
When your home isn’t using all of the energy your solar panels generate, your inverter tells your battery.
Charge your battery
The battery starts charging and stores the excess solar energy.
Give back
Once the battery is fully charged, excess solar energy is fed to the network.
Save after dark
When your system stops producing solar energy, the inverter starts discharging your battery so your home uses the energy stored during the day.
How to compare battery storage systems
When deciding on a battery, the cheapest system isn’t always the most affordable option. Comparing a battery’s cost against its total energy throughput (how much energy it will deliver over its lifetime) will help you determine which system delivers the best value.
To calculate energy throughput, multiply charging cycles by battery size. E.g. 3,500 charging cycles × 10kWh battery = 35,000 kWh total throughput.
A charging cycle is the number of times a battery can be fully charged and discharged before it reaches end of life. Some battery retailers offer a warranty guaranteeing either an energy throughput or a lifetime in years, usually based on whichever limit is reached first.
