Why Does My 300A Bridge Rectifier Draw Excess Current Charging RV Batteries via MPPT?

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)?Thank you for your opinions

Hijado,Couple problems here, based on my understanding of your setup. Please let me know if I got any of this wrong. Assuming you're using 120VAC with a 10 or 15A residential breaker. If you put that into a diode rectifier, you don't get 120VDC as an output, but rather an oscillating positive voltage that oscillates between vpeak and zero.As the voltage drops, your controller will try and pull more current to compensate, raise above rated load and pop goes the breaker. This alone is solvable, you could run this through a capacitor bank to level it off to something close to a DC voltage. But before you go buying a hundred bucks in capacitors...The next bit of bad news is that 120VAC rectified is not 120VDC, but about 170DC. VAC*sqrt2=VPeak. If your controller can only take 150v, you're going to risk damage to the controller. Here's a little info on that: https://www.daycounter.com/Calculators/RMS-Calculator.phtmlIn short, you need a more refined system to accomplish your goals that might make this solution no longer desirable. 

Thank you so much for your reply. Makes sense. I already bought capacitors and the waveform looks pretty flat on my scope. The voltage is a problem and I am about to buy a 2:1 transformer. 
Still- the question remains: Does my solar controller limit the current or do I need some external component to limit the current coming from my rectifier?On a side note, people ask why I don't just buy a battery charger. Well, they are expensive and big and I already have an excellent one: my solar charge controller. Thanks again.
