[RE-wrenches] Classic 150 100 amp utput breaker tripping?????

[Jay]

Hi Daniel

Is this a new classic with OCP? Or maybe they don't have it anymore?

What it sure sounds like like is a big load on the batteries, it hits faster than the AGS can start, and the caps in the classic are dumping into the super low battery voltage. If this is happening in the AM, guessing with enough light to get the CC alive 

If there is a trimetric, you can measure the lowest voltage which should give you some good info. Super low volts might mean a bad battery or too big a load or both. 

But I don't believe it's the other way around that the classic is causing any issues with the AGS/inverter

You could always try another CC and see what happens
