Due to the low voltage at the profile tower, we cobbled together a charging power system for it.
Voltage Prior to adding the supply, the voltage at the inside of the power interface panel on profile was 9.9V.
Charging system consists of a 12VDC power supply (white rectangular cube), PAM charge controller (didn't note which kind) and a battery, all in a white cooler. A second separate battery is also connected. Strung a new AC extension cord to this system. Left the cooler lid propped open. Will have to watch that this doesn't overheat.
Voltage a the profile power interface panel after adding the charger was 12.1 V.
Checked Checked voltages at downwind1 charge controller:
...
At unused output from charger: 13.5 V.
Inside downwind1 interface panel: 11.1 V (still seems low)
