This is all hypothetical but lets say that I have a bank of 8 6v Costco golf cart T105 batteries, hooked up to produce 12v output. With the right converter, how long would it take to charge this setup using the right generator?
And what would these 'right' converters and generators be?
Simple answer, there is no right 'converter' for that application. You need a two stage ‘charger’ with boost/cc & abs/cv.
Like many of the boondockers here, if you can manage to do your 'charging' in the morning, the genset and 'charger' will do most of the heavy lifting, i.e; the 50-80% portion, at the higher boost/abs rate. Then your solar would take over and finish off the remaining 80-100%. Weather permitting, of course.
Eight Costco T-105 clones have a combined Capacity of 880Ah at 12v, correct? If so, your average daily usage of 370Ah’s would bring them down to a 58% soc. Using a Honda 3000i to power a 100a charger, set at sufficient voltage to max out the charger’s 100 amp current limit, it would take 2 hours to replace the (-)193Ah’s of a 58-80% cycle. It would take about another 1-1/2 hrs to do the next 80-90%.
