2.2kW Solar Water Pump Inverter in Yangon, Myanmar

Project Introduction

In recent years, Myanmar's economic growth has been driven mainly by the agricultural sector. The local government sector has also given high priority to investment in agricultural infrastructure development.

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 3kW solar array，2.2kW pump inverter and 2.2kw pump and provides 2m³/h water for irrigation.

Project Products:

Pump:

Rated Power:  2.2kW
Rated Voltage: 220VAC  3Phase
Rated Current: 9A
Rated Frequency: 50Hz
Rated RPM： 2850RPM

Solar Pump Controller:

Drive Brand /Model：VEICHI / SI22-D3-2R2G
Rated Power/Current: 2.2kw/10A
Rated Output: 220VAC  3Phase
Input Voltage Range: 60VDC –450VDC

Solar Array:

The result:

The whole system is built by the lake. It is powered by solar power. It operates automatically and requires no manual monitoring or batteries. It saves electricity and fuel costs compared to homeowners who used to pump water through municipal electricity or diesel generation. In addition, solar power is green, non-polluting and low-noise, in line with the quiet and comfortable rural life that homeowners aspire to.
