First thing I see is that you seem to be relying on your 30a charge controller as a bonus current limiter, and I believe it is undersized for the 500w worth of potential. I’d get a larger charge controller and breakers...
I’m not seeing a connection between the solar or battery-inverter input terminals and the main 120v service breaker, or of the converter-charger back feeding thru the solar breaker to the controller, I believe it is unrelated to the solar...

Thanks for the reply 3 tons!
I'm not relying on the Charge Controller to do anything other than it's job of converting the panel voltage and current to what the batteries need. I'm okay with the panels being a bit oversized (if they are producing at their max...which most of the time they will not be). I'm okay if the Charge Controller limits its output to 30amps (if in reality it could deliver more if I have say a 40amp controller). I *assumed* the solar charge controller would output a max of 30amps. If it outputs more, that's fine (...I thought it was unlikely it would output more than 40 amps ever, but maybe I'm wrong).
I only wanted/needed ~200w. The panels were super cheap so I ended up buying two 250w panels. I upgraded to the 30amp MPPT controller, knowing that it could limit the overall power generation a little, sometimes. I don't care about that.
I'm hoping that the Converter Breaker popping has nothing to do with the solar system and inverter install. Since those two things basically tap right into the battery bank +/- terminals, it doesn't seem likely they would be the culprit. (right?)
What are the most common causes of the Converter Breaker popping?-Chris
