Add SOH for some inverters, implements #687

[MartB]

As discussed in #687, this should roughly implement what we know about the SOH registers.

Tested and working on my H3
Master: 2.01
Manager: 1.80

To Test:

• H3
• H3-Pro (likely to work)
• H1_G1 🚫 (Not supported, confirmed by SOH #686 (reply in thread))
• H1_G2 (Confirmed by Add SOH for some inverters, implements #687 #703 (comment))
• KH Series

Works on my H1-G2.

Thanks!

My H1-G1 doesn't appear to have this register. I can't find it in the spec for the pre-1.19 KH either. Do you have any documentation suggesting those should work? Where did you get the address 11104 from?

Please run pytest --snapshot-update to update the snapshot tests

#686 (reply in thread)
Got the 11104 from here, cant confirm if the H1-G1 or the pre1.19 KH works.

Thanks! I'll follow up on that thread, try and get to the bottom of if anyone can access it on a H1-G1.

[canton7]

Yep, looks like this doesn't work on the H1-G1 sadly.

@canton7 Thanks for following up! I removed all H1-G1 references.

@williamjeccles Mind testing register 37624 on your KH?
