Portable Solar Pumping System with built-in Battery

This is a side project for one customer from the Philippines, we have exterminated several good selling solar pumps in the market and found one big problem with them – unstable performance of the pump!

The solution is quite easy, but a little more expensive, that is to add a battery system with the solar panel, so the output of the solar panel can be adjusted by the batteries system.

Moreover, if there are additional power generated during the day time, the batteries can be used for lighting with DC12V LED bulbs at night.
