I have a 12 volt DC 9 amp water pump that I would like to power from a 110 watt 12 volt (17.2 volt at peak) 6.4 amp solar PV panel. I only want to run the pump when the sun is out, it's circulating water through water heating solar panels.
I'm not an electrical engineer so I'm hoping to find a easy and inexpensive way to connect these two in a way that won't burn out the pump.
I've read online about using a battery and charge controller, I'm not opposed to this idea but I really only want it to run when the sun is shining bright and heating the panels.
I've also read about using a "linear current booster", this seems like it would work, but the ones I found cost over $200.
I've tried connecting the solar panel direct to the pump, but that of course did not work.
So... does any one have any ideas? Photos of the labels of pump and panel below:
