How To Connect A Solar Panel To A Water Pump

The maximiser circuit converts sub optimal power to pulsed full power getting over the startup current issues neatly.

How to connect a solar panel to a water pump. In a sale i picked up a 115w panel with 37v output and plan to connect this to a 12v dc 50w pump via a voltage regulator. Connect the negative wire from each string to one end of a separate cb input of cb 4. Get panels which have an open circuit voltage about 1 5 times that or if it is listed a maxim power point voltage similar to the pump. You should have about 750 watts of panels.

Connect the solar panels by first opening the solar panel connector box and then using a multimeter to find the polarity of the solar panel. Before connecting the solar array to the solar pump system controller we must connect a circuit breaker cb between them. An even better solution is to also use a linear current booster lcb between the solar panel and the solar pump. They have a controller circuit available that optimises solar output for pumps etc.

It depends on the pump. Why solar powered water pumps are the ideal way to boost agriculture in remote areas and. An lcb decreases the voltage and increases the current output helping to handle the high current surge a pump needs to get started. Connect the positive wire from each string to one end of a separate cb input of cb 3.

Connect the output of the 3 positive cb s together. I am looking at a similar challenge a very simple solar powered pump that only operates when the sun is shining. 3 such strings will be thus formed. Check the nominal voltage that the pump runs at.

The voltage regulator came from e bay and is designed for golf cart use. Place 6 circuit breakers cb in a pvc box. Connect 7 solar panels in series to form one string. Connect the panels in series or parallel to match the pump voltage.

Most of the cheap solar pumps available simply wait until the solar panel output is sufficient to turn on then run.
