MPPT controller variable voltage frequency solar pump inverter build in VFD Three & Single phase

MPPT controller variable voltage frequency solar pump inverter build in VFD Three & Single phase

Solar pump inverter for solar energy water pumping system

YC energy YAOCHUANG solar pump inverter integrate MPPT voltage, convert 150-750V DC solar power to 220V single or triple phase & 380V triple  rated output to drive pump motor. It is build-in VFD, achieve various flow rate accompany with changing sunshine condition. The system can operate 6-10 hours long time in sunny days.

How should I maintain the solar pumping inverter?
Potential problem will happen during the operating of the inverter due to the temperature, humidity, dust, and vibration of the inside ambient of the inverter, for the long duration and stable running, the inverter should be examined once in a year.
Maintenance requirements
1)The examination should be carried out by a Professional person. And cut down the circuit before the examination  
2)Make sure no metal scrape is left inside the inverter, or else it would be damaged. 
3)Do not do any pressure resisting test as the electric insulation of the inverter has been tested before delivery. 
4)When there is a necessary to do the insulation testing of the inverter, connect all the input and output plug in short circuit, and it is prohibited to do the same to single plug. And please use a Meg-ohmmeter. 
5)Meg-ohmmeter is prohibited to use for controlling circuit. 
6)Disconnect the inverter and the motor when testing the insulation of the motor.
