90kW Solar Water Pump Inverter in Domingo, Dominica

Project Introduction

In recent years, the main driver of economic growth in Dominica has come from the agricultural sector. Local government departments also attach great importance to investment in agricultural infrastructure construction.

The challenge

The problem of energy and water sources is one of the most important issues many countries are faced with. Around more than 30% agricultural pumps are not available to connect with grid electricity due to poor power facilities. And 50% farms cannot get well irrigated because of poor water conservancy infrastructure.  Nowadays the cost of diesel is rapidly increasing，so the cost of maintenance on diesel generator pump system is very high. It is urgent and important to find a sustainable way for agricultural irrigation.

The solution:

Solar powered water pump technology is a very good solution to agricultural irrigation. The system consists of 115kW solar array，90kW pump inverter and 90kw pump and provides 60m³/h water for irrigation.

Project Products:

Pump: 

Rated Power:  90kW
Rated Voltage: 400VAC 3 Phase
Rated Current: 180A
Rated Frequency: 50Hz
Rated RPM： 2950RPM

Solar Pump Controller:

Drive Brand /Model：VEICHI / SI20-T3-090G
Rated Power/Current: 90kw/180A
