Troubleshooting dead solar kit controller
Full time and working from the road, so mostly we look for hookups, but maybe once a month, head off to dry camp. Decided a full solar setup wasn't cost-effective for our circumstances and instead bought a portable 100 watt solar kit from Renology. Control module is built-in and on the half dozen occasions we've used it, it's worked flawlessly to keep batteries topped off.
Yesterday everything worked fine with good voltage indicated and happy batteries. This morning, however, got anxious to switch over from generator (toast and ground coffee, you know) and while idling down to clear out the fuel line, I hooked up the solar to the batteries while generator had not yet shut down.
Solar controller appears to be dead, no display, and no power to the batteries. Hindsight tells me I must have damaged the controller ... does anyone have any troubleshooting suggestions (or confirmation this a lost cause and I just should replace the controller)?
Question: better to be a successful pessimist or a failed optimist?
