4 FAQs about Solar circulating water pump connected to battery

How does a solar water pump work?

The system uses a solar panel to charge a 12v battery, which in turn can provide power to the water pump. A pushbutton is included in the circuit, likely to control the activation of the water pump. The solar panel and the battery are connected in parallel, providing a stable voltage source for the pump.

Can a solar cell power a pump?

The solar cell does not have enough power for the pump. Another way to power the motor inside the pump is to use a battery. So we tried connecting it to a 12V 5Ah battery, and now the pump functions properly. We also add in another of the same batteries in parallel to increase the current they can supply by two times.

Why should a solar water pump have a back-up battery?

The back-up battery together with the grid supply will contribute to the uninterruptable power supply of the standalone solar water pump. The provision to feed the solar power back into the grid can offer an additional benefit to the consumers: to earn revenue.

Why do solar water pumps need a reluctance motor drive?

Therefore, a reduced-component four-phase switched reluctance motor drive is utilized to improve the cost-effectiveness and reliability of the system. The back-up battery together with the grid supply will contribute to the uninterruptable power supply of the standalone solar water pump.
