■ Stand Alone Solar Inverter Details
■ Stand Alone Solar Inverter Connection
BigBear LLC stand alone inverter has two usage methods:
1. Solar PV System: The electricity generated by solar energy is DC, and will flow into the battery to store energy, then the inverter converts the DC in the battery into the AC of home appliances. When battery power is lacking, it will automatic transfer to grid power for powering continuously.
2. UPS 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 fan, light, refrigerator, television, computer, air conditioner. When AC grid power is off, inverter will automatic transfer switch to battery power and convert DC to AC power.
