The general idea is that the rectifier maintains a -48 battery string at float voltage, and the load runs off the batteries. that's your ups functionality.
-48 not actually being 48, of course, float voltage for an AGM string is 2.25V per cell. More typically the 2v cells are in 12V units, those wired in series to achieve 48. So (2.25 x 6) x 4 = 54VDC thereabouts On Mar 4, 2016 12:26 PM, "Scott Vander Dussen" <sc...@velociter.net> wrote: > Trying to figure these things out!
