Suitable for residential and light commercial use, maximizing self-consumption rate of solar energy and increasing your energy impendence. During the day, the PV system generates electricity which will be provided to the loads initially. Then, the excess energy will charge the battery via SUN 12/14/16K-SG. Finally, the stored energy can be released when the loads require it. The battery can also be charged by the diesel generator to ensure uninterrupted supply in the event of grid blackout.
