Charge controller thinks battery is 24v - it's 12v?
A simple 12vdc system only running led external lights. Assembled the system on a bench, all good. Installed it and now the controller is treating the battery as 24v. Of course all paramaters now reflect that of a 24v battery and cannot be changed to reflect a 12v battery. Result is now a non-functioning system.
Anyone experienced this or can offer an explanation?
