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 |
| 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.
