Efficiency Test Results -MPPT Controller (Eco-Worthy) UPDATE

"From the frying pan into the fire" comes to mind :)

The controller keeps playing with Vmp so by the time you take one measurement the other that goes with it doesn't quite match so you can get a too wide spresd or a two narrow spread between the two measurements. Very frustrating but with practice, you can get it within reason.

I ignored any possible loss between battery and controller that might affect the percentage. I have two feet of #8 on pos and same on neg there, if anyone is fussy, that was at 14 amps and 13 volts.
