I have an off grid well using the Franklin Electric solar powered SolarPAK SubDrive system. Recently I've been getting a "controller overheating" error code (note: NOT the pump itself). Usually this happens right after powering on the system, but sometimes it will pump for a few seconds first. The controller is clean, in the shade, and cool. I replaced the small fan inside the controller, to no avail.
I can't find anyone who is willing to troubleshoot the system. Franklin Electric recommends replacing the controller, which is ~$6K (!). I'm considering switching to a standard AC powered controller powered off an inverter since that would be much cheaper, but does anyone have any ideas for troubleshooting my issue? Thanks!
