[EP600x2 Parallel] Obtain information about PV3 and PV4 (Slave device PVs)

[Skydev0h]

Greetings, Patrick!

It seems that information about PV3 and PV4 is not obtained when two EP600s are connected in parallel (DC PV x2 and AC PV x3 are only loaded about Master EP600).

I understand that it is not too easy, because 1200-1289 registry pack seems to return information only about Master device:

1200: 0103b400000000018f00000000000000000000000000320000006400000a8500000000000000000000006400000000000000000000000000000065000000000000000000000000000000650000000000000000000000000000006500000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000f29

We can see two DC PVs (type 64) and three AC PVs (type 65).
P.S. It seems that this information is encoded as "32" in the data - 3 AC PVs and 2 DC PVs.

Therefore it is very interesting how information about Slave device PVs should be obtained.

Judging from the APK decompiled code, it seems, that only 1200 section is parsed as PV information, therefore, it is possible, that either information about Slave device is pushed as section 1200 with some other options OR it may be required to set inverter number at some register to read information about the other EP600.

I tried looking at all *13 registers (PV1 voltage), but did not see anything alike voltage of PV3, that additionally confirms that to get PV3 and PV4 you first need to ask PBOX where to look.
