■ DC to AC 3 Phase Frequency Converter Details
■ DC to AC 3 Phase Frequency Converter Wiring Diagram 
We offer 2 optional working modes for 3 phase converter (transfer time≤4ms):
1. Home or Industry Backup System:
When AC grid power is available, inverter charges battery, at the same time, AC grid power bypass through inverter to home/industrial appliances, such as freezer, water pump, electric drill. When AC grid power is off, it will automatic transfer switch to battery power and convert DC to AC power.
2. Wind or Solar Power system:
Convert DC to AC power. When battery power is lacking, it will automatic transfer to grid power for powering continuously.
