Hi Guys, new here.
I have a not-trivial off grid setup consisting of 110 250 watt panels and two banks of 600ah 2v AGM's in 48v configuration. (total usable 600ah @ 50% dod).
I also have a non-trivial load on my inverters sometimes which is causing the banks to discharge at well over 100 amps each in some cases. This is obviously not optimal.
Is there a working limit on the number of parallel banks of 48v 2v cells I can setup? Like 4 or 6 or similar? I've read that charge controllers start getting odd towards the higher end but I have not been able to find anything to verify. I would like to increase the number of parallel banks to reduce the high demand load from the banks when my industrial machinery is running in my workshop. My property is fully off grid. Grid connection isn't feasible (WELL OVER $150k to connect, and 3phase not available).
Important Bits:
2 banks of 24 2v 600ah cells in parallel (48v).
2x Victron 250/100 Charge Controllers each with approximately 60ish panels connected in 6sxp (peak voltage about 242v OC)
2x Victron Phoenix 5000va 48v Inverters running split phase.
1x 15kw 48v three phase inverter (custom made by manufacturer) to run heavy equipment (This can pull 300 amps alone @ 48v)
110 250w panels in 6s18p configuration. I think the last two are actually 5s2p because you need 114 panels from memory to make it all 6s.
Yes, I run my system hard. Currently my batteries almost never discharge below 80% and I like it like that.
Thanks in advance
