Series 12v Chargers ?
Bestconverter ad says, "The PD9100L Series can be wired in parallel to charge at much higher current rates. They can also be wired in series/parallel to charge 36, 48, 60, 72 and higher voltage bat...

I think we have overlooked a problem with the 55 amp unit. When the current gets near 55 amps it will go into current limit and "fold back the voltage" as the the current will decrease. For example look at the VI curves for the unpopular WFCO9855. I suspect others are similar. I have not been successful trying to parallel my 100 amp Magnum and a WFCO9855. No joy yet!
Nope. The 55 amper starts off at 55 amps and stays there till the batts get to near the set voltage of the converter (14.8) So all during bulk, whether 24v or 12v bank that is no problem.
You should be able to parallel the Magnum with the 14.4v WFCO by setting the Magnum to 14.4v. However, if the WFCO will not do 14.4, but only the 13.6, that is another added problem.
Yes I have a bunch of converters over the years. Two 100s, a 75, and a 55, (all PowerMax) Plus a 7355 and a 7445 (Parallax) Long story! Never mind. (Also three different solar controllers--never mind that either :) )
I need a New Year's garage sale!
