Solar battery storage
Store surplus daytime power to use in the evening or during outages. Increase your self-consumption and rely less on the grid.
Discuss a storage solutionWhen to add battery storage
Use solar power at night too
Surplus daytime power is stored and supplied to your load in the evening instead of buying from the grid.
Backup during outages
Keep essential appliances running (lights, fridge, wifi, cameras) when the grid fails.
Optimize peak-hour costs
With time-of-use tariffs, a battery helps you avoid grid power during expensive hours.
Add to an existing grid-tied system
A battery can be added to a solar system you already have, depending on the inverter.
Choosing the right capacity
Battery capacity depends on how much electricity you want to use when there's no sun, and on your budget. SVPPOWER calculates it based on:
- Your evening load and the appliances that must keep running during an outage.
- The average surplus output of your solar system.
- Your current inverter type (hybrid or grid-tied only).
