I bought a pwm solar charge regulator from Amazon and hooked it the battery on my travel trailer and a 5 watt panel. It was my intention just to maintain the battery charge. It lit up but did not show voltage, a setup screen or any information on the screen. It was just a blank lit screen. I thought that this was weird so I checked the battery voltage with my meter. Battery was dead. I had the trailer plugged in but forgot that I had the converter turned off. So I flip the switch on the converter to charge the battery back up. Went back outside and the charge controller was smoking like smoke stack. I double checked the wiring and everything was correct. Did the voltage from the converter smoke this controller? The controller was for 12 or 24 volt systems and I only have one 12 volt battery.
what did I just learn the hard way?
thanks
