■ Pure Sine Wave Inverter Charger Application
BigBear LLC pure sine wave inverter usually has the following two application methods:
1. Home Backup System:
When AC grid power is available, inverter charges battery, at the same time, AC grid power bypass through inverter to home appliances, such as light, rice cooker, refrigerator, television. 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.
