[Question] Cannot load Battery from grid #565

Closed stefanheinrichsen closed 1 year ago

stefanheinrichsen commented 1 year ago

Describe the bug To my understanding my SolaX Inverter should be capable to charge the battery from solar (of course) but also from the grid. Idea is to charge at cheap times when having flexible contacts and not much sun.

This does not seem to work right now. I'm not sure if this due to the inverter firmware or due to this integration which is not writing to the correct registers.

Mandatory details

  1. Integration Version: 2023.09.4
  2. HA Version: 2023.10.3 on HAOS 11
  3. Inverter Brand: SolaX
  4. Plugin Used: not sure?
  5. First 6 digits of Serial: U30EE4
  6. Connection Method: MODBUS TCP via Ethernet directly to the Inverter
  7. Inverter Model: SK-TL 3000E

Additional context

I did set the charge/dischage times in the HA entities and changed the mode to "Forced time use". SolaxX Allow Grid Charge is set to "Both Allowed". I can see that during the times I specified as "charge time" the inverter stopps using the battery to power the house load. However it does not start to charge the battery as I would expect.

Any hint or link would be super great. Maybe someone has the same inverter here and is able to help or knows more?

I'm also totally willing to try things out. Maybe I missed some option or had a wrong combination.

Best regards, Stefan
