Number of batteries?

Currently have 6 hv25 on my h1 system, thinking of adding another two but have read that 7 is the max for a single phase system. Is that correct?

It appears so, 7 batteries and 1 BMS for single phase.

It's 7 on the original H1 (max 450v), but the KH and H1 G2 can support 8 I believe as they have a higher max DC voltage 480v.

Yes I think I found the same for the other inverters when looking up.
