Hi Dave, Only thing I would check is to see if lowering the eq by 1 volt changes anything. IE the batteries are just struggling to keep up.
But the CC should tell you what mode it’s in right? IE is it regulating or is it full power. Either in the menus or just looking at VMP/watts If it’s regulating then it’s on the OB side If it’s max power then it’s on the battery side Jay Peltz > On Apr 28, 2020, at 6:50 AM, Dave Tedeyan <dtede...@taitem.com> wrote: > > Hi All, > > I've got an outback system (Radian 8048A, 2 FM80, 16 Trojan L16RE-B) where > when the customer equalizes, the batteries hover right around the EQ voltage, > but will often dip to 0.1v less.
