I have an old gen 1 inverter. The spec sheet says a maximum of 4 batteries, yet it also states a battery voltage range of 85-450. I currently have 4xHV2600. Can I add another one?

Just to check it’s an H1 gen 1 (and not an AIO) you have ?

If it’s an H1 you can add up to 7 batteries - the big question do you have V1 or V2 Hv2600 batteries ?. The V1 is no longer available but occasionally comes up for sale on eBay - the V2 is still readily available.

You can add a V2 to a V1 system but it’s a lot of messing, you have to change the BMS to a V2 version and in all honesty mixed packs are never as good as singles.

It is an A10 and I have another v1 battery to add

Ok, your obviously limited by space but i’ve heard of people adding extra batteries externally to the cabinet - i’ve just never seen it myself.

Thanks
