WORKING MODES

Self-consumption Mode

Throughout the day, the power generated by PV system will supply household loads first , and then saving surplus energy to battery that can be used at any time, the excess electricity could be exported to grid.

Time-of-use Mode

Battery charging and discharging time can be flexibly set based on your local peak and off-peak electricity period to minimum the electricity bills.

Backup Mode

Back-up mode is able to maintain the battery in a charged state. When power outage happens, the battery discharges to power the backup loads.
