Due to the low voltage at the profile tower, we cobbled together a power system for it.
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.
The hope is that this will also increase the voltage levels at downwind1.
Checked voltages at downwind1 charge controller:
J3 (DC in): 12.8V
J2 (to battery): 12.2V
J1 (load): 12.1V
At unused output from charger: 13.5 V.
Inside downwind1 interface panel: 11.1 V (still seems low)
