I have two Renogy 100w panels (RNG-100D - wired parallel). I'll be installing a LiFePo4 battery bank soon(100aHr). I've been using an Epever Tracer 3210N MPPT charge controller for my old AGMs and it has worked well. It is LiFePo4 compatible but I can't seem to find information about limiting it to charging to 80% or 90% charge on the new batteries. Searching other forums it seems to be quite the task to program it; if it can be done at all. So, I'm thinking of upgrading to a smart ch controller. I'm hoping it is smart enough to be user friendly. I'm not confident about that though! I'm not one to monitor production and load beyond what my two ammeters tell me. So bluetooth is not necessary but it looks like that is the way the market is going. I just won't use that capability much.
My panels are rated as follows (each):
Pmax 100w
Voc 22.5v
Vmp 18.9v
Imp 5.29a
Isc 5.75a
I'm not sure which value I multiply by two and add 25% to determine a charge controller that fits (Imp or Isc). I see Lauren has the Victron 75/15 smart Ch Cont. Would that be suitable? I'd like to keep the price around $100.
Thanks,
Tim
