Thats why we liked the triplite inverters. They had a 33amp charging circuit (required 40 amp breaker), and the charge voltage varied based on the type of battery. This was my fear with using Smart Ups. They were designed for lead acid batteries, which have different characteristics than Gel batteries, or the other type (VLRA?).
One thing we didn't like about the Triplite Smart UP XL series at high VA, was they were deep as hech, to accommodate a lot of internal batteries. I preferred a unit that had a shorter depth. The Triplites also have different Voltage requirements for its batteries. I found one of the models that did support 48V. Although I did not look into APC's XL series yet, as Patrick suggested. Its tough getting the facts out of APC and trriplite, because oif course they all want to sell you theirown battery packs, which are way over priced by a factor of 6X minimum.
