Hello Q,
To answer your question; I am currently at Quartzsite running on 1000amps 12v Lifepo4, 1900watts solar with all Victron controllers and inverter/chargers. This is my third coach with similar systems and this set-up is the sweetest yet, but…
I’m not sure you need to jump to lithium to meet your goals.
Lots of good questions and points brought up so far. So just to be clear you have (2)-225amp 12v AGM’s, which would be group 8d’s weighing roughly 140#’s ea. or (2)-225amp 6v AGM’s, which would weigh roughly 70#’s ea.?
If you have the 12v’s then I don’t see how they could be fully charged, at a very rough 25amps/hr peak charge as it would take 10’ish plus hours of full sun to replenish the 250 amps, indicated by the 11.9v reading in the morning.
I am guessing you have the 6v’s for a total of 225amps@12v and you are burning roughly a 125amps by morning if the batteries were 100% at the end of the day. Again I think the amount of solar you currently have will not allow for a full charge.
I wonder if you just need to add more solar to achieve a full charge and maybe that will be enough to get thru the night with a few extra amps left over in the morning.
If you’d like to talk lithium-PM me with your #.
