To keep the batteries charged and to run the 5er when boondocking 2 Yamaha EF2000isv2 vs 1 EF3000is ( 2 will give the max flexibilty, the most watts at the least cost (2X1600w=3200w vs 2800w). in the works if possible 3 235w solar panels.
I supect that i will have to change the charge controller for the batteries. what i need is comments and suggestions. thanks

OK, you're already getting lot's of warnings about the "Lithium" part of the Batt. now I want to make you aware of some other factors!!!
I am just going through the same procedure, or rather have gone, I am building my system up from doing it too small the first time!
So Let Me Warn You, First Do Your Research!!! then go shopping........ NOT the other way around!!!
We have a 40' American Eagle with all the amenities and it had 4x225amp Class C 6Volt batteries for the house =450Amp.hrs 12Volt and then the engine batt.'s
I upgraded the House Batteries to 4 x L16 types =4x425Amp 6Volt =850Amp.hrs 12Volt, when you need that many amps I don't think you still want Lithium?
And the Batt, I bought came with a 7 yr. warrantee.
Now we arrived at those numbers after long deliberations of how much power we think we need to Boondock for some what unlimited times with equal amounts of solar feeds (850 to 1000Watt) (I know Watt's are not Amps but all that will become clear) Or you can look at a whole bunch of samples and say we have a budget and that's it !!!
We wanted to use the generator as little as possible, but we do have a pretty big one if needed (7500W) then If you can afford it go for a good MPPT Controller, $8-900.00 but well worth it if you can swing it.
Now Panels you can safe if you want, I was let to believe that I had to buy the more expensive MonoPhotovoltaic panels BUT that is not true any longer the difference is getting smaller and smaller and if you go for the more expensive MPPT controller there will be no difference!
Cables is another important factor that you need to calculate and do absolutely correctly, including Fuses and Breakers, Voltage losses can add up quickly and fires can start even quicker.
What I did Is find a reputable company that sells all the parts and get them to layout / Design the system for you to your spec and then you buy their parts that way you have sombre to go and ask questions If you run into problems !!! It was Free.
But first You can do lots on your own with DIY information from the internet, but becare-full what you believe and put into action without checking out !!!
I Hope I Helped,
