OK I see. So again the bottom line is we are not plugging in, we are not on the cord for weeks until we camp again, we are on gen, so...will the converters do what we want? You need to answer yes or no in the end and move on. Only thing that matters is where is sg and soc when you start and how long to get to full. Not being smart arse just think of it as hands off, as if someone else walked in, used it, ran it down, charged it up. Did the converter work and how long did it take?
will the pm4b converter meet my needs? a resounding NO!!!
how big a charger do i need to replace it, just for abs charging? apparently about 40amps.
not bad for 4 days work, eh? (and bfl thought i was a slow learner! lol).
For your "abs charging" as soon as the 75er drops to 13.6 you want to replace it with a charger that does 75 at 14.6 (NOT 40) Or you can modify the 75 to stay at 14.6 or move that up to 14.8. whatever!!!!
Your 430ah battery bank will easily accept 140a charging instead of only 75 at 50% Just add some more chargers that go to at least 14.6 same as the 75. That will speed up the 50-70 part no end. Your only problem now is getting from 70 to whatever in shortest possible time.
That would be by keeping the other chargers running at their 14.6 and replacing the 75 in the line up by a 75 that will stay at 14.6. Amps will taper from 140 to however far down you want.
It remains that whatever you do amps will be down to about 20a at 14.6v when you get to 90% SOC (5a per batt) and about 8a when you are at 97% SOC (2a per batt) But you have a Trimetric AH counter so you can use that.
You have all the info you need right here in this thread from several folks. You need to take the time to hoist all this in. Take a break, sleep on it, nobody's brain can work that fast. At least mine can't--I took months if not years to become such an expert. Oops DW seems to have another opinion on my progress made. :)
