Solis S6-EH3P(29.9-50)K-H-LV — is this planned/supported?

Hi, I'm planning a stationary storage project using two Tesla LFP packs (~60 kWh total) with a Stark CMR v2, and I'm trying to figure out which inverter to commit to.

I see Solis RHI-3P(5-10)K-HVES-5G is listed as supported. I'm specifically interested in the Solis S6-EH3P30K-H-LV (the 230V IT-grid/low-voltage variant of the S6-EH3P series, used mainly in Norway where we have an IT earthing system without neutral). Battery voltage range 150-800V, 2 independent battery inputs, CAN/RS485 communication.

Questions:

Is the S6-EH3P(H)-series (as opposed to RHI-3P) on the roadmap or tested at all?
Does the existing Solis CAN implementation in Battery-Emulator apply to the S6-EH3P-H-LV, or is the protocol different between the RHI-3P and S6-EH3P families?
Has anyone tested two independent battery banks on BAT1/BAT2 with two separate EV packs on a Solis inverter?

Happy to test on my own hardware once it's set up, if that's useful to the project. Thanks for the great work on this project!

Follow-up on question 3: I read the Double Battery wiki page and understand this is for parallel-combining two identical packs into one virtual battery (and that Tesla 2020+ double-battery support is still "testing ongoing in PR"). That's not quite what I'm asking about — I want to use Solis' native BAT1/BAT2 "Dual Input" ports (two independent battery banks, each with its own CAN/BMS reporting to the inverter), similar to how FoxESS/Sofar dual input is mentioned on that page.

Would this require two separate Stark CMR / Battery-Emulator units (one per Tesla pack, each wired to its own Solis battery bank), or is there a different recommended approach for feeding two independent packs into a Solis inverter's two battery ports?

I have not tested this as my two batteries are just wired in parallel on the HV DC side and use a single Stark (with an extra relay driven out of one of the GPIO).
You would need to absolutely verify that the two battery inputs on your inverter are not sharing a common DC bus - I know some inverters do that on the MPPT inputs. Do you have the datasheet ?

Also just notice that looks like a low voltage DC inverter ?

I have a S6-EH3P10K H with the AU suffix. We use MEN earthing here, so the PE and N are connected at the distribution board, the PE has 2m rod driven into the soil.
The inverter works well with Battery Emulator
