Thank you for this. The newest being the CATL?sunsynk:
Sun-batt = 5.32kwh 80%dod (4.2)
L5.1 = 5.12kwh 90%dod (4.6)
G5.3 = 5.32kwh 90%dod (4.9)
CATL = 5.12kwh 100% dod (5.1)
these are the only ones i've come across whilst i was researching installers in the uk (not to say that there aren't any more variations)
afaik they are not intercompatible so you have to stick with a single model if you want to expand your battery setup and cannot mix-and-match
