Submersible Solar Well Pump with Built-in Controller — Solar Fountain Kit S_3SP2-100-D4860-750BI

This Solar DC brush-less submersible pump is built for applications such as agriculture, deep well water extraction, household use and small fountains. The solar panels feed the unit directly and the pump automatically starts and stops, offering a compact design, modern appearance and easy operation and maintenance. For daily runtime estimation: if electricity consumption is divided by a power generation efficiency of 50%, the pump can be rated for 6 hours a day and 8 hours a day. When selecting solar panel capacity, first confirm the pump's input power. Then either divide that input power by a panel power generation efficiency of 65% (up to 70%) or multiply the input power by 1.5 — the resulting value is the nominal solar panel power required to run the pump.
