Without battery storage, surplus electricity generated during the day is exported to the grid. With a battery, that surplus is stored and used in your home during the evening and overnight — when electricity rates are highest.
Adding battery storage typically increases self-consumption from 30–50% to 70–90%, significantly improving the return on your solar investment.
Sizing, compatibility and installation.
A battery sized to your evening and overnight usage — and matched to your inverter — delivers the best return.
Measured in kilowatt-hours (kWh). A typical UK household uses 7–8.5 kWh per day. A battery that covers your evening and overnight usage maximises the value of your generation.
Not all batteries work with all inverters. The Kit Builder automatically matches compatible battery and inverter combinations for you.
Battery installation typically requires a qualified electrician for the electrical connection — even for systems within the 800W plug-in limit.
