Hello. I am working on an RV with solar panels and a 60A solar charge controller. Unfortunately the charge controller only works with solar panels and has no input for line power to charge the battery bank. No problem I thought. I got a 300A bridge rectifier, hooked it up to the solar charge controller in the attempt to trick it thinking there are solar panels feeding it. The charge controller accepts up to 150V DC so I should be fine there. Also the controller limits battery charge to 60A. When I the rectifier into the outlet, it works for about 2 seconds. The charge controller shows the voltage and sends 60A to the batteries. - Then the breaker blows. Obviously, the rectifier is drawing too much power. But why? if the controller sends 60A @ 14V to the batteries, at 115V that's only 7.3A (It is an MPPT controller which converts voltage to current with 95% efficiency). Why is the rectifier drawing much more and how could I limit the current (if my controller apparently fails at doing so)?
