0.75KW To 22KW Three Phase SG320 Series Solar Vfd Solar Pump Inverter For Solar Pumping System
ZK SG320 series Solar Pump Inverter description
Solar Pumping System including water pump,solar panels and solar pump inverter.Converting solar direct current into alternating current to drive water pump.it support dc/ac input.
solar inverter adopts Max Power Point Tracking and proven motor drive technology to maximize power output from solar modules.
When solar power is not available, the controller can be switched to an alternative AC power supply such as a generator or AC mains. The inverter provides fault detection, motor soft start, and speed control as well as plug and play ease of installation.
Solar Pump Inverter Features
1.automatic start and stop of the inverter when there is enough power available. ( auto/manual).
2.Maximum power point tracking functionality.
3.Built-in flow measurement and sensorless flow calculation.
4.Standard asynchronous motors as well as more efficient permanent magnet syn. motors. (PMSM).
5.Remote monitoring.
6.solar pump inverters ensure reliable power supply throughout the day with on and off-grid compatibility.
7.Embedded pump-specific features such as dry run detection.
8.Minimum power input protection.
9.Maximum current protection.
10.Minimum frequency running protection.
11.Flow and generated energy showing.
