Steca Solarix PLI 5000-48 // Axpert MKS 5K-48

[ma-schmitz]

Hello,

I use the above inverter and would like to read it with ESPHome. Unfortunately, I do not get proper answers from this inverter and just do not know where to look further. I have attached the log files and my ESPHome configuration. Maybe someone wants to help me.

I use a nodemcu-32s, MAX3232 RS232 to TTL and a DC-DC converter.

Thanks in advance

Please enable the debug output of the uart component by

uart:
  - id: uart_bus
    tx_pin: GPIO22
    rx_pin: GPIO23
    # most devices use 2400 as baud_rate
    baud_rate: 2400
  debug:
    direction: BOTH
    dummy_receiver: false
    after:
      delimiter: "\n"
    sequence:
      - lambda: UARTDebug::log_string(direction, bytes);

and flash the ESP again. Please provide a new log capture. This time the raw traffic should be part of the log. I assume the component doesn't receive a valid response of the inverter it's probably an echo of your request.

It looks like your wiring isn't correct or your inverter responds with the same message you are sending. Please double check your setup. Sometimes the RX/TX lines between the inverter and the RS232 converter must be swapped. Sometimes the RX/TX lines between the RS232 converter and the ESP are the root cause and must be swapped.

so, I never swapped the RS232 side, now at least I get data. But if I am not mistaken there is still a lot missing. Or am I thinking wrong and now everything is as expected?

[syssi]

Could you provide some more log lines? It looks like the QPIGS respone isn't processed. Did you add all relevant sensors to your configuration YAML?

[ma-schmitz]

so, I have tried many things again. It looks good so far - I am getting data from the inverter.

What doesn't work so well is changing the modes (outpu source priority). If you change from POP01 to POP00, it happens very quickly. If you change back, however, it takes between 2 and 10 minutes until the command is executed. What is the reason for this?

POP02 does not change to any mode, so this error message appears:

[11:21:45][D][switch:013]: 'steca-solar-inverter output_source_priority_battery' Turning ON.
[11:21:45][D][pipsolar:856]: got command: POP02

espHOme_config.txt steca-solar-inverter_logs.txt

[syssi]

Please update your ESPHome version. The inverter doesn't accept the POP02 command because of a wrong CRC. This was fixed recently: https://github.com/esphome/esphome/commit/e0555e140f8e8b7debe26c498dbf115cfd52bff5

[ma-schmitz]

ok, yes now the switch to POP02 works. Is there a solution for the slow change from POP00 to another mode (POP01 / POP02)? The change to POP00 always works immediately, the change to another mode between 2 and 10 minutes.

[syssi]

I don't have an answer here. Could you check the uart traffic? I assume the "delayed commands" are pushed immediately to the inverter and the inverter does process the command/instruction that late?!

[ma-schmitz]

yes, the commands are sent immediately and the inverter delays them.

Is it possible to get "solar charge priority" as a switch?

And before I forget: Thank you very much for the effort and support.

[syssi]

The modes are available as select box in future but it's work in progress.

[ma-schmitz]

I just noticed that not all commands are supported. For example, I use MCHGC060 - unfortunately this is not released. Can this be changed?

We are talking about this code fragment: https://github.com/esphome/esphome/blob/dev/esphome/components/pipsolar/output/__init__.py#L50-L74

There is a config setting called possible_values. Here you can define deviating values to the sensitive default.

You could try something like this:

sensor:
  - platform: pipsolar
    pipsolar_id: inverter0
    current_max_charging_current:
      name: "${name} current_max_charging_current"
      possible_values:
        - "MCHGC010"
        - "MCHGC020"
        - "MCHGC030"
        - "MCHGC040"
        - "MCHGC050"
        - "MCHGC060"

[ma-schmitz]

Thanks for the quick reply, but now I get errors when compiling.

current_max_ac_charging_current: name: steca-solar-inverter current_max_ac_charging_current current_max_charging_current: name: steca-solar-inverter current_max_charging_current

[possible_values] is an invalid option for [current_max_charging_current]. Did you mean [on_value]?
possible_values: 
  - MCHGC010
  - MCHGC020
  - MCHGC030
  - MCHGC040
  - MCHGC050
  - MCHGC060

input_voltage_range:

[syssi]

My fault. I made two mistakes:

1. We are talking about outputs not sensors
2. The possible_values must be floats (10.0, 20.0, 30.0, ...)

Please try

output:
  - platform: pipsolar
    pipsolar_id: inverter0
    current_max_charging_current:
      id: inverter0_current_max_charging_current_out
      possible_values:
        - 10.0
        - 20.0
        - 30.0
        - 40.0
        - 50.0
        - 60.0

[SeByDocKy]

You can check the PVbrain.yaml (https://github.com/Bandit-17/PVBRAIN/blob/main/README.md) that give exemple how to proceed

[syssi]

@SeByDocKy Thanks for your hint: https://github.com/Bandit-17/PVBRAIN/blob/main/pvbrain.yaml#L349-L369

[ma-schmitz]

it works.
