■ Micro Inverter Solar Panel System Details
■ Micro Inverter Solar Panel System Wiring Diagram 
BigBear LLC micro inverter solar system usually has two application methods:
1. Home backup system:
When AC grid power is available, inverter charges battery, at the same time, AC grid power bypass and stable voltage through inverter to home appliances, such as light, fan, rice cooker, kettle. When AC grid power is off, inverter will automatic transfer switch to battery power and convert DC to AC power.
2. Wind or Solar Energy system:
The electricity generated by solar or wind energy is DC (direct current), then inverter will convert DC to AC power. When battery power is lacking, it will automatic transfer to grid power for powering continuously.
