here is my current setup.
yellow is high voltage 120/240
red is 12v
blue is my current victron 120x2 12v
gray is the current battery bank 17KW(usable) industrial AGM
green is my 7500 watt genset in the front.
I want to add solar but charge controlers are ridiculous at 12v. I am adding 5400 watts of panels. and I would need about $ 5,000 worth of controllers for that so I am on a mission to switch to 48v.
here is my thought:
I add an EG4 6000XP (orange) on a 50 amp receptacle. when not on shore power I will just plug the RV into that. the 6000CP can do 2 120v legs at 3000 each which gets me to my 50amp even when on batteries. it will feed through my 120x2 which will keep my 12v charged up.
In the center of the chassis, I plan on adding more batteries. I have a source for industrial AGMs at $50/each 210ah usable. I am thinking 16 in between the frame rails (plenty of space and great for weight distribution. That will give me almost 50KW of storage on the 48v side. this will be maintained completely from solar.
the main reason for keeping the Victron is how easy it is to grid limit and boost. I am often at a place with only a 15-amp circuit. with the Victron, I can limit input to 15 amps and boost with the batteries to keep my ACs running. I think the 6000XP can grid limit but the docs mentioned it only for battery charging so I don't know if its exactly what I need. It also can't boost, it either uses a grid or switches completely to the battery if the grid can't handle it. that is way less convenient.
If I swap the Victron out completely, I have other worries about the 6000XP. it has 2 legs 180 out of phase but in a coach, we never combine them so phase doesn't matter. there is nothing 240, just 2 legs that never connect. however, when I hook up a dogbone to a 30 amp circuit I am going to feed both inverters the same phase. Is it going to freak out? is it going to try and rotate a phase?
the reason I when this route is it's cheap.
5400 watt solar $3000
6000XP $1300
50KW batteries. ~$1000 with wiring
~$5000 and I should be good.
what am I missing? Should I look at different solutions?
