2.2kW Solar Water Pump Inverter in Bangkok, Thailand

Project Introduction

Veichi SI20-D5 series 2.2kW solar water pump system was successfully installed in a village in Loburi, Thailand. The project is invested by the local government to irrigate paddy 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 4.8kW solar array，2.2kW pump inverter and 2.2kw pump and provides 3m³/h water for irrigation

Project Products:

Pump: 

Brand: LEO
Rated Power:  2.2kW
Rated Voltage: 380VAC 3 Phase
Rated Current: 5A
Rated Frequency: 50Hz
Rated RPM： 2850RPM

Solar Pump Controller:

Drive Brand /Model：VEICHI / SI20-D5-2R2G
Rated Power/Current: 2.2kw/5A
Rated Output: 380VAC 3 Phase
Input Voltage Range: 250VDC –780VDC

Solar Array:
