The BBWX-2 AC distribution box can change over the power sources between grid power, PV power, and battery system by automatic AC components.
In sunny days the PV power from solar panels is higher than the AC loads consume, the extra power will be storage in the battery system.
When the PV power is lower than AC loads consume, the BESS will output the power.
After the energy in the BESS is lower than a level, the AC distribution box changes the power to grid power source automatic.
We customize AC distribution box for different requirements.
