Here’s what I’ve got:
It’s time to program the Epever. I’ve done a lot of digging around, looking for the proper settings and have read the article “How to Find Happiness With LiFePO4 Batteries”, and everything I read says to program the charge controller as though it’s working with a single 24V battery. But one question is still vexing me.
Will there be any conflicts between the parameters of the individual 12V BMSs and the 24V settings of the charge controller (low and high voltage disconnects and reconnects, for example)? I know the importance of maintaining both batteries at the same SOC and can deal with that. My question has to do with the fact that each BMS has settings based on 12V while the CC will be set up with settings based on 24V. Is the fact that the BMSs are in series automatically make this a non-issue?
For completeness, I've attached a .pdf file showing settings for Epever 4215BN, including those recommended by SOK for the 12V 100AH battery, some additional 12V settings I've found, and the settings I *think* may work for my setup (they're basically the 12V settings doubled for 24V).
Any feedback/advice would be appreciated.
Thanks in advance!
- Two SOK 100AH batteries in series for 24V
- Epever Tracer4215BN 24V 40A charge controller w/MT50
- Giandel 3000W pure sine wave 24V inverter
- Four Rich Solar 100W panels in series (total of about 90V)
