Noted: We suggest solar panel power should be 1.3-1.4 times higher than solar pump power ,
And solar pump inverter power should be higher level than solar pump.
When solar pump distance to inverter higher than 100m,
It should be equipped with Output reactor or higher level power inverter.
For Solar panel,total VOC less than Maximum DC voltage of inverter and Solar panel vmp is recommend
530V for 380V pump and 305V for 220V pump.
Advantages:
1, Suitable for single phase pump, three phase pump. Permanent magnet synchronous pump
2, Support PV input and AC input at same time, make system work 24 hours.
3, Built-in MPPT technology with up to 99.9% efficiency.
4, With water level detection function, automatically regulate the pump flow to prevent dryrunning
5, Water full protection function, when the water is full, inverter will stop.
6, Support optional LCD keypad, you can know every parameter's meansing on display,
and you can monitor any 5 group parmaters situation.
7, Support optional GPRS module, you can remotely monitor the system situation.
