Growatt "Mod" Series and battery's

[DKphfrDK]

Hi Solar friends

I found the grid-tie Growatt "mod" serie 3 phase inverters interesting, with battery storage.

But in the manuel it says - only compatible with Growatt Ark Xh Battery.

Do this mean I cannot use another vendor eg. a server rack battery or DIY battery eg. from Seplos
