A home battery can increase self-consumption and, with suitable controls, respond to electricity prices. Its value depends on usable capacity, efficiency, cycles, warranty, installation and your actual solar surplus.
A sensible first check
No sales pressure and no guarantee: start with an indication and have the final design and quotation checked by a qualified professional.
Use your own property and energy figures wherever possible.

A larger battery is not automatically better. Capacity should reflect daily surplus, demand outside sunny hours, seasonal variation and the maximum charging and discharging power.
Compare the battery, inverter, energy-management system, standard installation, possible meter-box work and optional backup capability. Ask whether quoted capacity is nominal or usable.
Use conservative assumptions for price differences, efficiency and cycling. A technical lifetime does not guarantee a particular financial return.
Frequently asked questions
There is no general national ISDE purchase subsidy for a standard home battery at the time stated on this page. Tax or local arrangements can change, so verify current official information.
Only systems designed and installed for backup operation can do this. A standard grid-connected battery may switch off during an outage.
It depends on solar export and demand. Use a calculation based on your own figures rather than household averages alone.
