I would go for the 2 x 24/100ah if at all possible. Reason being keeping the 28 batteries balanced could be an issue, more chances of a defective battery, and you don't have to deal with a Battery mgmt system (BMS). I do know what its like getting supplies to islands and that sucks. Keep...

Thanks for your input and like the way you labeled everything , but I'm afraid most of what you said is over my head. There seems to be no simple fix for this which is what I wanted to make sure there was not. I'm so impressed with all the help that is available on this site.
I was wondering how you are making out with your scc settings. I have the epever also and the amps stay to the max (30) until the batteries reach 27.5 (under Charge) then cuts off all charging until it goes down to 26.5 (no Charge, a little load, 50 watts). I thought the amps should go down...
The panels are 4 trina 250 watt. I am getting the 60vdc. But only 3 to 4amps. Measured by a victron 150 /35. Charge controller. 2 series strings in parallel.
I think the state of charge dictates to the charge controller how much the battery needs, not how much comes from the panels. I.E. bulk, absorption, float. I understand the irradiance factors involved.
I obviously should not use the term STC loosely. I was simply trying to make understood the conditions were very good, i.e. full sun, good angle, low temp. lower temp being better than stc.
Got it. I contacted them also and they responded. But Their wording was a little ambiguous. "do not use yellow(ground) wire, if house neutral is connected to ground connect black neutral with it". The house neutral is connected to ground at the house main panel so I take it to mean connect...
oh, so for example if the 12 v 200ah battery is reading 12.8 it may not be 20% ? I mean in bulk does it not mean that you would put 14.4 volts in and a higher amp? and does not the controller figure out what the battery gets by voltage?
yes, mine does not do that, it stays at boost till turns off charge when it thinks batteries are full. And since there is 20+ amps coming in it thinks its fully charged when its really only 70-80%. I don't understand
Interesting conversation here as I have killed two 3k inverters and wondering if its the ATS or my wiring. I have the neutral grounded to house ground.
I have a similar system as you but i had 2 inverters go bad. I am concerned about the grounding /neutral set up. I have a grounding bar for the 2 inputs and 1 output. Do you connect the neutral to grnd?
Also Do you connect the grnd of the inverter to the grnd of the grid. I'm thinking of grounding all 3 circuit grnds to 1 bus bar which goes back to grid.
