75A MPPT Solar Pump Inverter


Inverter For Water Pump 37KW

Product Description

3 Phase 380V 37KW 50HP 75A MPPT Solar Pump Drive Inverter
ZK SU100 series MPPT solar pump inverter mainly features:


Built-in adaptive high-precision photovoltaic array MPPT algorithm, accuracy more than 99%

Input power can be solar DC and Grid AC

Effective waterless operation mode. If water pressure is low, reduces the frequency or stops by itself

Utmost water flow output, irrespective of the environment

LED displays the real-time system status and parameters

The soft-start of the motor avoids the water hammer effect and improves system service life

Built-in comprehensive protection and diagnosis mechanism

With overvoltage protection, overcurrent protection, over-temperature automatic frequency reduction and other protection functions; DC input anti-reverse function

Easy operation-Easy to install, no need to set parameters, ready to use, and has a one-key parameter recovery function

Ambient temperature for using: -10 to +55˚C.

How to select the solar panels for your solar pumping system?


Input voltage, power solar selection
Pumps model Inverte models Vmp Voc Total Power of solar arrays
110VAC pump T1 (for 110V) 130VDC 156VDC

≧ (1.3 to 2.0) rated power of Pump
It is also depend on the quality of solar panels. The higher the power input, performance will be better

220VAC pump T2 (for 220V) 310VDC 372VDC
380VAC pump T3 (for 380V) 540VDC 648VDC

Solar pump inverter MPPT efficiency more than 99%, but also
have to consider many factors of solar radiation. Like the quality of the solar panels. If the output frequency can’t get to 50Hz/60Hz, please try to add more solar panels, but voltage can not big than the inverter Max inout voltage.
