Brian, I installed a watt meter on the treadmill motor that I am using, but we don't have any clean sun right now. but here are the readings at 4pm. mostly cloudy. managed to get a reading with haze over the sun.
volts 62.7
amps8.6
watts539
The solar pump with the controller has a digital readout, the other day with full sun it read 82v. The pump calls for 550watts, I didn't have an amp reading, but it looks like it would need 6.7 amps at 82 volts.
