Location

Sindh-Pakistan

Purpose

Agriculture irrigation

Water source

River. water depth 8-10m, 2m from river to tank.

Requiredments

Pakistan is a large country with traditional agricultural production. Due to the  shortage of elecricity, when agriculture

irrigation requires water, it often loses power, which will have a  great impact and  loss on the cultivation of local

farmers. In order to solve the actual pumpong difficulties, SINCREA solar pump irrigation system was introduced

to meet the needs of agriculture irrigation.

Solution

Water pump

3KW AISI304 submersible pump,3P 380V Rated water flow:20 m³/h; Rated lift head:10m

Solar panel

4.8KW,15pcs 320W Mono solar panel in series

Solar pump inverter

SINCREA,Model:SV500-004-4TB4KW Solar pump inverter,3P 380V

Mounting bracket

Ground fixed Q235 hot galvanizing stell mounting bracket

Accessoies

DC/AC cables, MC4 connector, water level sensor, DC/AC multi-meter, installation tool, etc.

Benefits

Adopting SINCREA 3KW solar pump system, the 4.8KW solar panel drive the 3KW pump by the 4KW solar pump

inverter. The system pump water from the 8m depth river to the tank, and then flows to each farmland through

the channel, working 6-8 hours a  day, 100-150 cubic  metersof water can be pumped for  farmland   irrigation,

solving the  water shortage due to power outage and water shortage, fully automatic operation,and no manual

operation.

Location

Muscat-Oman

Purpose

Farm fishery, animal husbandry

Water source

Tank

Requiredments

The farm is located in the mountains and deserts, with drought and long sunshine radiation all the year, incon-

venient for water supply, unable to meet the demand for electicity in the farm, and the high dependence of the

fishery on water. Considering the power grid limit, the electricity price during the day is high and the slestricity

price is loe at night. So to install SINCREA solar pump power supply system to provideprotection for fish farming

and farm electricity, saving electricity costs.

Solution

Water pump

2pcs 15KW water pump +8pcs 7.5KW pump+ 4pcs 4KW pump

Solar panel

150KW,480pcs 300W Mono solar panel in series and in parallel

Solar pump inverter

SINCREA, Model:SV500-015-4TB+ SV500-7R5-4TB+ SV500-004-4TB15KW,7.5KW,4KW solar pump inverter,

3P 380V

Mounting bracket

Ground fixed + roof type Q235 hot galvanized steel bracket

Accessoies

DC/AC cables, MC4 connector, water level sensor, DC/AC multi-meter, installation tool, etc.

Benefits

The SINCREA 100KW ground fixed +50KW roof-type photovoltaic pump power supply system is installed in the

farm. During the day, all solar energy is used to power the pump, and the electricity consumption at nightis low.

Now saves  $1,500  in  electricity bills per  month, which  not only solves the demand for electricity, but also saves the whole cost of electricity.
