Greetings fellow Solar DIY'rs,
I have (2) 80 amp charge controllers connected to 600 amp bus bars. I have (3) LiFePo4 24v battery banks, 100A BMS, connected in parallel each with its own 150 amp fuse then to the bus bar. [(3) 390w bifacial panels in series on the first controller and (2) 390w bifacial panels in series on the second controller]
If 2 banks go offline, or reach capacity, does this create a situation with the bank that is still charging? I suppose the BMS would limit the charge to 100A but don't want to rely on that. I could set a lower Charging Limit Voltage on the second controller but that won't help if 2 banks go offline and 3rd bank is at 50% of charge.
I'm currently in the build phase but have the opportunity to break off 1 battery bank and 1 charge controller if combining the charge controllers is a problem. I also have an older 30 amp charge controller w/(2) 300w panels on hand.
Charge controllers are Epever Tracer 8415 AN. I haven't considered connecting the charge controllers in parallel but can if it can address the possible issue identified above.
Thank you for your time.
