Hello there. I've tried to read as much as I can about 48v systems and 50 amp RV's but I'm not entirely sure how to get myself out of this bind, or at least the easiest. I had planned to put a SP6548 from SunGoldPower in with front storage along with 3 of their 100Ah server rack batteries. Everything was going well until I learned that 50 amp is 120 volt 180 degrees out showing as 240 volt. Didn't know that. I'm moving into this RV full time at the end of this month and everything is already set. I do not have any solar installed yet, this is just to be preemptive and be able to run things longer without the generator.
My options seem to be:
A) TRY to return the SP6548 and get a TP6048 which is the 120/240 split phase. Downsides is overall less solar input possible, and it weighs 73lbs, also the SP6548 got a little scratch on the top of the casing when I was trying to put an m10 bolt through a tight area so I'm not sure they will even take it back. I could end up shipping it in just to find out they won't take it.
B) Just route one leg to the inverter and then split that single leg into two wires going to the two main AC breakers? Then maybe just purchase a second one of the sp6548 since I was eventually going to try to take it all off the RV and put it on a house eventually. Downside is expense, I don't know how well this would really work, and somewhere I'd have to terminate a hot leg. And weight but only marginally more weight than the 73 lbs TP6048.
C) Not sure if this one works at all but maybe? Route one leg to one side of the circuit breaker straight off of the surge protecter (as it already is), and then route the other leg through the inverter and back to the other side of the circuit breaker? This screws me up thinking about Neutral though (learned on helicopters and DC mainly)
Stinks too because I didn't figure out this problem until after I already figure out how to install it in.
Any help much appreciated. Sorry if things are redundant, I really did try to read a lot of these threads about similar issues but neutral always is where I get stumped.
