Solar Water Pump Circuit using Battery and MOSFET
In my earlier article I showed about solar water pump circuit using relay. That design works, but relay makes clicking sound and relay contacts can burn after long use. So now here is the new version. This project is Solar Water Pump Circuit using Battery and MOSFET instead of relay. MOSFET has no moving parts, […]
Solar Water Pump Circuit using Battery and Relay
This project is about Solar Water Pump Circuit using Battery and Relay. It uses one 18V 20W solar panel, two small 12V batteries, one relay and diodes. The circuit can run a 12V DC water pump. Battery stores power from solar panel and relay controls when pump run. It is a very simple circuit and […]
