PV Status

[ombonbon]

Hallo @johanmeijer , I've been using grott for more than a year now. Yet, I still have a question: what is the meaning of pvstatus values?
At the moment I see pvstatus is 12.
Again, thank you so much for your great work.

PV status is a little bit depending on inverter type. I gave to say that the documentation I have is not very clear about it.

The first documentation I have (for the TL-s inverter types) only show the following states:

0:waiting,
1:normal,
3:fault

For the SPF type inverters I see the following States:

  0: Standby;
  1; （No Use）
  2: Discharge;
  3: Fault;
  4: Flash;
  5: PV charge;
  6: AC charge;
  7: Combine charge;
  8: Combine charge and Bypass;
  9: PV charge and Bypass;
10: AC charge and Bypass;
11: Bypass;
12: PV charge and Discharge;

For SPA types (and SPH/MIX) I see and additional status field: uwSysWorkMode with the following states:

0x00:waiting module
0x01: Self-test mode, optional
0x02 : Reserved
0x03 :  SysFault module
0x04 :  Flash module
0x05 ：PVBATOnline module,
0x06 ：BatOnline module,
0x07 ：PVOfflineMode module,
0x08 ：BatOfflineMode module

To be honest I am not sure at this moment that the SPA layout (in test) supports this state field.

Thank you so much @johanmeijer . Mine is an SPF. I can now translate pvstatus based on your status list.

If you need anything more check the modbus documentation for SPF:

@ombonbon can we close this one?

Sure @johanmeijer , I thought it's automatically closed when I select a reply as the answer...

Thank you very much for the link to the document @rany2 .
