Wont I need a BMS for each string? I'll probably do the 3p16s.4 strings x 50V x 280 Ah = 58,000 Ah (gross)
Maybe you use 80% to 90% of capacity, 45 kW to 50 kW
Sounds like 3 strings would do it. Or 4, a bit extra, if you want.
Then you have to chose between 3p16s and 16s3p (how many BMS, max current, etc.)
That's exactly what I'll do. What's the rec bns? Even with 6k in batteries it'll help me sleep!Yes . Bms each string. Then to common busbar. Out from there to inverter.
I've got 6 strings of 16. Each with a rec bns.
Slightly pricey. But then with 12k in batteries, I sleep well at night.
