Home battery storage
Keep more of the energy you make.
A battery can move solar energy from the middle of the day into the evening—and may support off-peak charging with a compatible tariff.

A day with a battery
Energy changes with the light.
A typical energy day
Solar powers the home
Generation meets household demand first. Surplus can charge a battery or export.
What to compare
Capacity is only one number.
Usable capacity
The energy you can actually draw from the battery, measured in kWh.
Power output
How much demand the battery can meet at one time, measured in kW.
Warranty
Usually expressed as years, cycles, retained capacity—or a combination.
Backup
Many systems need extra equipment to power selected circuits during an outage.

Sizing storage
Big enough to be useful. Not bigger for the sake of it.
The right capacity depends on evening demand, surplus solar, charge rate, tariff and how often you expect to cycle it. Veyzo’s estimate shows a range; the installer confirms the final design.
