SFBattery Solutions

Hybrid power at a price you can plan around.

Solar, battery, generator and grid in one controlled system. We quote it as a cost per kWh over 20 to 25 years, so payback and finance are easy to compare.

How a hybrid system decides where power comes from

The controller follows the same order every minute of the day.

Solar firstDaytime loads run directly from the array.
Battery nextSurplus solar charges the battery; the battery covers evening and peaks.
Grid when cheapOff-peak grid power tops up the battery if the forecast is poor.
Generator lastOnly during a long outage with a flat battery.
