100% thanks Chad, yea luckily my wife smelled something off (heat shrink glue melting) and shut it down. All parts are delivered to our next campground so I can start the retrofit tomorrow. Also as shown in the diagram I am converting my 8 battery bank from 8 in parallel to 4 sets of two. Everything will be in 4/0 once I convery it. Also one other error I made on my initial install was putting the 12v dc out after the blue sea switch on leg two. So all DC + AC was pulling through that same 6awg wire. As I mentioned I had been keeping a close eye on consumption, this is the first time I was away that we werent on 50 amp/pass through power. glad it wasnt worse!

Yea no doubt it was a lot of power. Roughly 1500 Watts but this should be more than manageable with the system given proper gauge cabling ie 4/0. the thing I am not sure of is how the Victrons should run while connected to 30 amp. I had removed "switch as group" and it seemed to do ok, until the cables melted the switch. 6AWG cables probably the cause there. But is that the appropraite configuration for dual multis when hooked up to a 30 amp pedestal.

Yep totally agree Chad, I hadn't gotten to replacing the wiring from my original install. I usually am at the trailer so I was monitoring the consumption, but when I was gone my wife ran a few to many devices (dryer/elec water heater/ and then some that burnt it out. here is my new drawing with 4/0 for all battery/inverter wires. I am open to any feedback. Also any advice on how to properly set up the system to run on 30 amp would be greatly appreciated.

It was, I figured it out, unfortunately my wife had to go without power for two days. It over heated and melted the battery shutoff. It was passing through power on one leg and the other inverter was pulling too many amps/watts? through the other leg didn't blow the 300 amp fuse though. Upgrading to 4/0 wire but I am still not sure how to properly hook up my system on a 30 amp to prevent that in the future.

Good Morning All, We are currently parked outside okc (I am away for a few days for work) the RV is plugged in to a 30 amp service. The dual victrons are set to split phase 180 auto and not switched as group. THe power completely shut off yesterday, my wife checked primary fuses and tried resetting multiplus and power cycled everything. Power no longer passing through and Leg one will not re-engage inverting and other multiplus seems to function to charge only. I have run out of ideas. Trying to come up with something my wife can do to get power back on. any help or ideas would be greatly appreciated thanks!
