4kW Solar Water Pump Inverter in Tunisia

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 10kW solar array, 4kW pump inverter and 2.2kw pump and provides 15m³/h water for irrigation.

Project Products:

Pump:

Rated Power: 2.2kW
Rated Voltage: 220VAC 3 Phase
Rated Current: 10A
Rated Frequency: 50Hz
Rated RPM： 2920RPM 

Solar Pump Controller:

Drive Brand /Model：VEICHI / SI23-D5-004G-A
Rated Power/Current: 4kW/16A
Rated Output: 220VAC 3 Phase
Input Voltage Range: 150VDC –450VDC

Solar Array:

The Result:

The smallholder only needs to pay a small proportion of the down payment to the dealer and pay the installment every month as agreed. After one year, he can fully own the solar water pump system. Previously, due to the lack of irrigation system, the irrigation of the farm mainly depended on precipitation. When the dry season comes, crops often die due to lack of water when they are about to mature. With this solar water pump system, customers no longer have to worry about the irrigation of fields.
