Curious as to what you are gaining by switching to the 2X inverter charger? The inverter is still rated at 3000 watts and the inverter output is still 120V single phase.Well I'm glad I have some help to install all of this. Looks like I bought the wrong inverter which has now been 2 months from Amazon and I can't return it. Should have bought the 2x unit because this is a 50 amp coach. It does 240 volts which this will only do 120.So we are going to have to get creative with the wiring and put in a separate AC panel with three breakers in the battery Bay. Then we will be able to run the 120 side of the hot water heater. I will not be able to run the block heater on the motor which is fine. I will not be able to run the AC units which is fine. No problem running fridge, all the receptacles, and the microwave.
Actually what I have is going to work just fine and the 2x would not be necessary. Not going to be running AC units because my panels and battery Bank are not big enough for that. Right now there is a 30 amp breaker going to the old inverter. Plan is to change that to a 50. Then go to a subpanel with three breakers. 2 20s and a 15. One breaker will be for the microwave. One will be for all the outlets in the coach. Then one will be for the 120 side of the hot water heater. That inverter is actually rated at 2600 watts of appliances even though they call it a 3,000. The fridge is drawing about 2.5 KW hours per 24 hours which figures out to 100 watts per hour. The GE microwave draws 700 to 1,000 Watts. And then I don't remember but I know we looked up the hot water heater as well. I just want to be able to watch a movie, run the microwave, and have the refrigerator running along with the hot water heater and it looks like that should all work. Apparently that inverter is actually rated at 5500 watts short-term for I think 30 or 60 seconds when something starts up.Curious as to what you are gaining by switching to the 2X inverter charger?

Something to consider before you switch to a 50 amp feed to your charger/inverter is the output breaker size of your generator. Is that 50 amps as well?Actually what I have is going to work just fine and the 2x would not be necessary.

Two filters for venting. Once I put a fan in there hopefully that will work but yet keep the sand out of there. The bezel that holds the upper flat filter and the filter itself have to be installed after the box is in since my dimensions were so tight. Four of the six sides on the box done. That was a bear to get in there. Very close to needing a break and walk away from this thing for a while.

Is one of the air conditioners on the same main line as the inverter? If so, are you planning on moving it to the opposite line? A lot of work but it will be worth it. Solid work, next level for sure!
Water heater and microwave and don't forget the battery charger and AC unit on the same phase. Battery charger will reduce its out put if your pass through AC loads need the additional amps. Total connected load on that phase is what you need to figure out not just the inverter charger loads. Do you have a energy management system in your coach?Or maybe bump it to a 35 amp breaker. Either way I think I need to replace that 12 gauge wire with a 10 gauge for that size breaker. It looks like the microwave and hot water heater are only pulling 20 amps so this should be okay.
