My IP 22 12/30 has been the only power source charging my 12v Battleborn house battery. It is powered from an inverter connected to start batteries/alternator -works great never any problems, Recently I added 2x 100 watt solar panels in series and wired a 100/20 controller into the Battleborn house battery and if I run solar controller and IP22 at the same time the IP 22 is over heating, it also made a clicking noise. The solar works fine no issues.
