37kW Solar Water Pump Inverter in Nile, Egypt

Project Introduction

In July 2021, VEICHI SI23 series 37kW solar water pumping system was successfully installed in a village in Egypt. The project was invested by the local government for irrigating rice fields.

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 49kW solar array，37kW pump inverter and 37 kw pump and provides 60m³ /h water for irrigation.

The result:

How about "solar priority with grid complementary" in solar water pumping system? Under the condition of simultaneous power supply of solar and AC power supply, the priority of maximum utility using solar power generation, and automatically blocks or accesses the AC power supply as the supplement power supply. This function can improve the use efficiency of solar power generation and reduce the consumption of municipal electricity, thus reducing the electricity cost of farmers and ensuring the safe power supply during the busy farming season.
