Products Description
KEWO SG320 Pump inverter solar pump inverter mainly features:
1. Drives well all kind of AC pump, including PMSM.
2. DC/AC power input.
3. MPPT efficiency more than 99%.
4. Can auto start in the morning if customer required.
5. Bulid in auto sleep-wake up function.
6. Dru run protection, (no need to add sensor).
7. Protect motor well, like over current, over voltage, over load protection.
8. Automatic detection of DC bus voltage, no need set by yourself.
9. Can monitor and control by GPRS (External).
