Hi. I have been solar at my home for about a decade with a lead acid battery system that I assembled myself, so I have a good basic knowledge. My battery bank on this system is just now weak enough to need replacement, but that is a separate thing from what I am doing today. What I'm looking for is information on the nuances of LifePO. I'm putting together my second system...independent of the first. It is...
3060 watts of panels, wired for 120 volts or so (nine 340 watt panels, wired in threes)
Midnite 150 controller (capable of 83 amps...64 amp is nominal at 48 volts for 3060 watts)
100ah LifePo battery
Chinese 6kw PSW 220 inverter (has charger too)
Transfer switch to switch to grid when depleted...maybe, if I can this undocumented transfer switch to work for me.
What I'm wanting is some education on the nuances of setting up a new 48 volt lifepo cell bank. The cells are brand new, and measure 3.26 to 3.28 volts, with the majority of them measuring 3.27. The BMS is included, but very basic. I have no external control over it, and must simply trust that it is setup acceptably (I may "graduate" later to one I can control with a computer).
My main question at this time is...do I need to parallel the cells for a while to equalize them with only a 0.02 volt difference? If so, how long should it take?
