KEWO Sun Great Series Solar Pump Drives/Inverters

Solar pump drives advantages:
Kewo sun great series solar  pump drive is positioned in environmental-friendly and economical PV market, the product is applicable to PV pumping system, replaces water storage with electric storage and needs no battery modules. The direct current generated by solar modules is input to the inverter and then converted into the alternating current to drive various pumps directly. Additionally, the output frequency is adjustable in real time according to sunlight intensity change.
Fully automatic system using variable speed drive compatible with AC, 3-phase, submersible and surface mount pumps, and high efficiency PMSM Pumps. The system is composed of a PV generator, a pump and a solar pump drive. Based on the design philosophy that it is more efficient to store water rather than electricity, there is no energy storing device such as storage battery in the system. The system is prepared to be combined with a elevated water storage, e.g. water tower or an uphill tank installation.

System connection and commissioning.
An enhanced version of KEWO motor AC Drive( variable speed drive of motor speed and torque control), compatible with DC power and AC grid input.
Note*: Only allow one power source input at a time.
1. Connect DC power Positive ( P ) and Negative ( N ) terminals to input R, T terminals of drive.
2. Connect output U, V, W terminals of drive to 3 phase AC pumps. ( No driving for  DC pumps and Single AC pumps).
3.Connect water level sensor to drive if need water tank level detecting.
4.Connect remote controller GPRS module ( option) if need remote monitor controlling function. (option )
5. IP54 solar pump drive cabinet customization make is available including( AC/DC switchover, AC and DC breaker..), or IP54 module also is available.
PS: In built AC/DC manual switch, AC/DC circuit breaker, pumps connection terminals in cabinet.


Easy installation and commissioning.
1.Dc voltage of solar arrays in serials need large than 1.15 times of Vmpp of drives.
For example: For 4T series, recommend 540V*1.15=621V; For 2S series, recommend 311*1.15=357V. (Voc)
2.The selecting power of solar arrays need large than 1.3 times power of total pumps.
For example, 0.9kw above for 0.75kw pumps, 2.86kw above for 2.2kw pumps.
3.Commissioning steps.( Please wait 30s after switching on for Voc detecting by iverter itself.)
