Solar Pump Inverter

Sigineer Power is a professional solar pump inverter manufacturer in China.

A solar pumping system includes solar panels, a solar pump inverter and a pump.

The solar water pump inverter is built-in with MPPT solar charger to maximize solar power production, it converts DC current into alternating current(three phase or single phase 220v ) to driver asynchronous motors such as water pumps (centrifugal pump, irrigation pump, deep well water pump, swimming pool pump, etc.)

An induction motor or asynchronous motor is an AC electric motor that can work in a wide range of frequency.

The solar pump inverter power ranges from 1.5KW to 22KW with AC output voltage at 220Vac(3PH), 380Vac(3PH), 220Vac(single phase).

The pump controller is built with variable frequency drive (VFD) technology to adjust the motor frequency from 0 to maximum according to the solar radiation.

The 1.5KW to 5KW models also work with AC input so that the pumps can automatically start with AC power when PV production is insufficient.

It starts and stops automatically to reduce maintenance costs.

Its powerful software allows users to customize the specifications such as motor rotate speed.

The built MPPT solar charger have very wide PV input, with PV Voc of 450V for 1.5KW and 2.2KW models, and PV Voc of 900V for 3-13KW ones.

The WELL port will work with water level sensors in the well and tank to avoid flooding and exhausting.

The GPRS port works with our GPRS module for remote monitoring.

The GPRS port is a RS232 port, users can plug in a RS232 to RS485 connector and connect the inverter with their own PC software for monitoring.
