2. ◆ Introduction of solar pump system Solar Pump system consist of PV solar panel, solar pump inverter, water pump. It is a kind of water pumping system powered by solar energy. PV solar panel absorbs sunlight and converts sunlight into DC (direct) current, then solar pump inverter converts it into AC (alternating) current to drive the water pump motor finally. Solar water pump has a satisfactory use in the solar energy sufficient area especially in areas without electricity or countries. As solar is a sustainable green energy, it must be vigorously advocated by governments in the near future so that the market demand of solar pump inverter will increase.solar pump inverter

3. 1. Irrigation 2. Household 3. Extract Ground Water 4. Public Places 5. Industrial Application 6. Drip irrigation

4. Panel mainly makes up from silicon material. There are six parts in one panel. 1: Tempered Glass 2: EVA 3: Battery Piece 4: Backboard 5: Aluminum alloy 6: Connecting Box 7: Silica Gel

5. Tempered Glass 1: Protect the Panel body such as Battery piece and Solar chip 2: it must be high light transmittance (more than 92%)

6. EVA Film is used to bond tempered glass and Battery piece ( solar chip)

7. It absorbs sunlight and then generate the DC Electricity

8. Backboard has sealing waterproof and insulation function

9. Aluminum alloy protect the panel body and solar chip from extrusion.

10. 1: Connecting box protect electricity generation and pass the DC current to Solar pump inverter. 2: Silica gel used to seal elements and the Aluminum Alloy Frame.

11. Main Function 1: Transform the DC current Into AC Current 2: Protect the Pump Motor (soft start) 3: Energy Saving

12. SI 10 SI 20 We do SI 10 and SI 20 solar pump inverter

13. 1: Veichi Solar Pump Inverter uses the independent intellectual property rights of Dynamic VI maximum power point tracking control method which also called MPPT. This technology has fast response, perfect running stability, improve the tracking effect when the sunlight intensity change quickly. Do you know what is MPPT?what is MPPT 2: Veichi SI10 has high current transformation efficiency(up to 98%) so that it has the perfect energy saving ability.

16. 1:Advanced MPPT control Method 2:Protection design for over load, over current, over voltage, lightning. 3: Suitable for Three-Phase Asynchronous Motor 4: Set the pump speed range flexible 5: Aluminum alloys Body Frame----hard to deformation 6: Nice appearance 7: Explosion-proof design 8: CE certification
