Eco-worthy 20a MPPT controller

The you tube video early in the thread pointed out the temp sensor in the case. I've seen the controller drop the amps from 12 to below 6 when the case heated up in direct sun and bring them back up once it was placed in the shade and cooled down. Too bad i didn't have a DVM on the battery to see what happened to the volts at the same time.

I would seriously consider remoting this sensor to a battery terminal. On my PWM controller it improved the behavior, dropping back charging volts as the battery warmed up.

Any empirical data on how much voltage drop per degree the sensor buys you?
