■ Best Solar Inverter for Home Details
■ Best Solar Inverter for Home Wiring Diagram 
BigBear LLC best solar inverter 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, refrigerator, television, air-conditioner. When AC grid power is off, inverter will automatic transfer switch to battery power and convert DC to AC power.
2. Wind or Solar Power System:
The electricity generated by solar or wind 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.
