■ Household Inverter Details
■ Household Inverter Wiring Diagram 
BigBear LLC inverter usually has the following two method of application:
1. House Backup System:
When AC grid power is available, inverter charges battery, at the same time, AC grid power bypass through inverter to house appliances, such as rice cooker, refrigerator, aic-conditinoer, etc. When AC grid power is cut 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 energy is DC (direct current), inverter will convert DC to AC power. When battery power is lacking, it will automatic transfer to AC grid power for powering continuously.
