Growatt MIN series battery requirements

[Aloysius]

where did you get them for 2500?

While doing some digging I found a document fully describing the Growatt ESS protocol: https://watts247.com/manuals/gw/1_1xSxxP_ESS_protocol_rev _23_20171128.pdf
(also attached for posterity)

This looks like maybe for the older 48V batteries only, but unclear. Maybe this is a start for the HV batteries.

It would be fantastic to be able to buy a LEAF pack or similar and wire it straight to Growatt grid-tie inverters, with a small module to trick the inverters into working.
