Howie, The timer does not reset when voltage dips below EQ, it just stops counting. So sometimes after 3 hours of EQ, the timer may have only counted down 30 minutes.
Jay, I did try lowering the EQ voltage. When it was set to 62V, the voltage would hover at 62.0 and 61.9, then when it was lowered to 61.6V it hovers around 61.6 and 61.5. Lots of good info and ideas here, thanks all. -Dave *Dave Tedeyan, PE* Senior Engineer | Taitem Engineering, PC 110 South Albany Street | Ithaca, NY 14850 o. *607.277.1118 x121* f. 607.277.2119 www.taitem.com Solar • Sustainability • Energy • Design Certified B-Corporation since 2013 On Tue, Apr 28, 2020 at 7:46 PM jay <jay.pe...@gmail.com> wrote: > Hi Dave, > > Only thing I would check is to see if lowering the eq by 1 volt changes > anything.
