Here is the summary of the situation:
I noticed that the battery monitor I have wasn't showing any amps flowing into the battery. I checked all the components and connections, but could not find any obvious issues.
*4 x 200w 12v rich solar panels
*2 x 6v 250ah in series reading 12.3 volts
*Panels disconnected I read 12.3 at the controller from the battery
*Panels connected I read the same
*Panel input shows as 88v but .5a with full sun and no clouds at 1:30pm
*Controller error code reads E0
*Battery light on controller is solid
*Panel array light is slow flashing, and reads "Boost"
*I show no amps flowing into the battery, measured with battery monitor
*Battery monitor shows charge when using shore power, or when vehicle running
*Bluetooth adapter stopped working
Few days later I was able to test all of the panels individually, and each one read roughly the same values: 22.5v and 6.38a
I checked voltage/current of the array at the terminals on the controller and it read: 90.2v and 6.32a
The controller shows the array at 90.2v and 0.5a, with no current being delivered to the batteries that currently read 12.4v
I disconnected EVERYTHING from the controller, and it stayed that way for about 20 hours. I then reconnected the battery, then the bluetooth module, then the array. I then checked voltage and current at the array terminals and it was 89.7v and 5.76a (not as sunny). The controller said the array was 89.7v and 0.5a, and sent no current to the battery, still reading 12.4v. The bluetooth adapter also still does not work.
At this point it sounds like my 6 month old charge controller has simply gone bad. Does this seem accurate, or is there another troubleshooting step I'm missing?
