KEWO Solar Pump Inverter with MPPT Functions

Solar Pumping system becomes more and more popular, it can be applied to daily ( underground water), agriculture irrigation, forestry irrigation, desert control, pasture animal husbandry, water supply for islands, wastewater treatment engineering , and so on.
In recent years, with the promotion of the utilization of new energy resources, solar pumping systems are more and more used in municipal engineering, city center squares, parks, tourist sites, resorts and hotels, the landscapes and fountain systems in the residential areas. This system is composed of a solar array, a pump and solar pumping inverter, or GPRS remote control model.
Based on the design philosophy that it is better to store water than electricity, there is no energy storing device such as store battery in the system.

Benefit of solar pump system.

Features of Solar pump inverter.

KEWO solar pump inverter features

Solar pump inverter technical Specification with good hardware design

SG30 Solar pump inverter with good software design

Software updated with MPPT design based on following solar inverter, ABB, Danfoss, Delta, Lorentz, INVT, VEICHI, SAJ.

Control mode: VF, vectorization VF, senorless vector control 1, sensorless vector control 2

MPPT function: always performance MPPT for gain highest efficiency

CVT: When sunlight is good, can select CVT control for excellent stable frequency output.

Dry run function: When little water or no water for pumping to protect pumps.

Maximum current protection: set maximum current protection is available

Minimum solar input power: When low power input, inverter no work

Stop frequency: Lower than stop frequency, inverter no work

Sleep mode: if lower than sleep voltage, inverter go to sleep, it will wake up when DC voltage rise.

Flow and generated energy calculating and monitoring

A lot of fault protection. Short circuit, ground short circuit, phase loss, over current, overheat…

Built in RS485 interface, it is easy to connect GPRS remote controller.

We developed it base on ABB, Lorentz, Delta, Danfoss , INVT and VEICHI---- That is why we are Good performance and better.
