[RE-wrenches] Sol-Ark 15K and HomeGrid - Comm Cable Pinout

[Jason Szumlanski]

Does anyone know for sure what the correct pinout is on the communication
cables for this pairing? Sol-Ark has multiple battery integration guide
versions.

Some show two wires connected to pins four and five on the inverter and
seven and eight on the battery, respectively. In another version of the
guide, four is connected to eight and five is connected to seven. In yet
another version, a green wire is introduced. I have tried all three
combinations, and none work.

I can't get a straight answer out of either manufacturer, and of course
they're both pointing fingers at each other regarding my battery
communication issue.

Sol-Ark is sending a firmware update and recommended a factory reset.
That's the next step, but it doesn't answer the question about the correct
pinout.
