I think I finally got the electrical sources all sorted out, but let me know if I'm off base.
The two 4K trace inverters only operate certain electrical devices. They include microwave, refrigerator, TV's, VCR, Sat Dish and electrical outlets. Everything else requires shore power or generator. I was under the impression that an A/C could be run off the inverters, but no can do. At least now I know if I lose the inverters, I still have the cruise airs and heat pumps, kick heaters, hot water heater, all the other appliances and of course the house heat and hot water off the webasco.
Seems like each converter does something different. One thing is for certain in these all electric buses, managing the power is a must. 50 amp shore power really doesn't get you much, especially if your using 2 A/C's. The article on the other board about reducing the bulk charge time was great and I set mine up to only go 20 minutes on shore power. When dry camping I will go back to the full 2 hrs.
Another good tip was the changing of the inverters shore power to 15 amps each when on 30 amp. I guess some do this automatically, but mine is an older one.
Taking a shakedown cruise this weekend to Nashville just to make sure all the bugs are worked out prior to POG.
