KEWO Solar Water Pump Inverter For 3 Phase 220V 15kw

Product Overview

Description

 

PV Series High Efficiency MPPT Solar Pump Inverter

Solar pump inverter controls and adjusts the soalr water pump system operation and converts the DC produced by solar array into AC to drive the pump, and adjust the output frequency in real-time according to the variation of sunlight intensity to realize the maximum power point tracking( MPPT). The pump,driven by 3-phase AC motor, can draw water from the deep wells or rivers and lakes to pour into the storage tank or reservoir, or directly connect to the irrigation system, fountain system, etc. According to the actual system demand and installation conditions, different types of pump such as centrifugal pump, axial flow pump, mixed-flow pump or deepwell pump can be used.

 

                                                                       

Solar pump inverter features

1.Suitable for driving all 3 phase induction AC pumps, for PMSM high speed pumps is option.

2.Control mode, local control, auto start/stop, GPRS remote control.

Local control - interfaces through the opertion pane(keypad)

Remote control - interfaces through external terminals control

GPRS remote control is option

3.Maximum power point tracking (MPPT) with fast response speed and stable operation.

4.Dry run (under load) protection.

5.Motor maximum current protection.

6.Low stop frequency protection.

7.Dual mode input, compatiable with DC and AC power input.

8.The PQ (power/flow) performance curve enables calculating the flow output from the pump.

9.Digital control for fully automatic operation, data storage and protective functions.
