Hello everyone posting some set up stuff because it was very painful to research and piece together. Hopefully this can help someone. I can explain the set up for anyone who is in a similar situation with an RV.
Watching this one. Doing on a 1975 FMC with very limited real-estate. EG4-LL probably more accommodating based upon space. No cellar. Want panels to be low profile. Can probably do 1000 watts worth with 4 250s. 29' FMC 2900R. Please keep us posted on results. For this old machine - the 12 volt may do better integrating. 50 amp service. Have some Victron - bought for 12v but interested in 24 and 48.
