My panel 48v 730w mono is about 100m away from my controller/pump 550w dc. The controller has a mppt. I am using 4mm solar cable. I am then using 1 inch pipe trying to run the water about 6 meters up over a 100 meter distance. In midday sun, I am able to pump water, but not when I attach the outtake pipe. It seems to just run but not actually push any water out. The controller is saying it's at about 1950 rpm, 38v , 4 amp and 150 to 170 w.
What's the biggest issue? The panel to controller distance? I can maybe shorten it to 85 or 90 meter
How can I test the solar panel to see what it's output is?
