pvoutput values don't look right

[gservat]

Thanks for the rewrite @bohdan-s! I just got around to trying it today. My config is as follows:

inverter:
  host: sungrow.gateway
  port: 8082             # Default for modbus is 502, for http is 8082
  # slave: 0x01           # Default is 0x01
  # timeout: 10           # Default is 10
  # scan_interval: 30     # Default is 30
  connection: http     # options: modbus, sungrow, http
  # model: "SG7.0RT"      # This is autodected on startup, only needed if detection issues or for testing
                          # See model list here: https://github.com/bohdan-s/SunGather#supported
  smart_meter: True     # Default is False, Set to true if inverter supports reading grind / house consumption
  # use_local_time: False # Default False, Uses Inveter time, if try uses PC time when updating timestamps (e.g. PVOutput)
  # hybrid: False         # Default false, if you have a Hybrid (battery) set to True
  # logging: 30           # 10 = Debug, 20 = Info, 30 = Warnning (default), 40 = Error
  # level: 1              # 0 = Model and Solar Generation,
                          # 1 (default) = Useful data, all required for exports,
                          # 2 everything your Inverter supports,
                          # 3 Everything from every register

exports:
  - name: console   # Print Registers to console, good for debugging / troubleshooting
    enabled: True

  - name: pvoutput      # Publish Registers to PVOutput
    api: "<key>"

    parameters:
      - name: v1    # Energy Generation

        multiple: 1000

        register: total_active_power    # Current Generation (Power)
      - name: v4    # Power Consumption
        register: load_power            # Current Home usage (Power)
      - name: v5    # Temperature
        register: internal_temperature  # Inverter internal temperature
      - name: c1    # Cumulative Flag,
        value: 1    # If using v2/v4 set to 1

In pvoutput.org, I'm seeing all zero values except for temperature, which I guess makes sense based on the values of the registers:

Register                                 Value

I'll admit I still don't fully understand what each field in pvoutput means 😆 I expect energy/power/average to be 0 given it's 9:30PM here, but I thought "Power Used" would show how much I'm consuming from the grid (meter_power).

[gservat]

Is it possible that total power used by the household is equal to total_active_power + meter_power?

[rark-ha]

Just checking that in your actual config file you have the API and KEY set.

  - name: pvoutput      # Publish Registers to PVOutput
    api: "<key>"
    sid: "<sid>"

[bohdan-s]

@gservat I have updated the Readme to add some clarity, thanks. Basically: total_active_power = power generated by inverter meter_power = power reading at meter box

so if meter_power is +ve, power is being IMPORTED from the grid, if its -ve then its EXPORTING. total_active_power + meter_power = house consumption

e.g. if total_active_power = 5000 (5kw generated now) + meter_power = -2000 (exporting 2kw) then your house consumption is 3000 or 3kW

[bohdan-s]

@gservat if your load is always 0, I may have to add "extra" register that is total_active_power + meter_power.

You can also try "level: 2" or even 3 and see what other details your inverter returns.

yeah - i redacted those.. it's not an issue with the connection to pvoutput but more in the data itself.

[gservat]

Yeah, looks like load_power is always 0 for me. I was thinking of adding a check that if load_power is 0 then set load_power to total_active_power + meter_power. Is this what you had in mind?

I've you're producing 3595W and your consumption is 242W then you should be exporting to the grid.

Are you sure you have a smart meter installed (or installed correctly)?

Does your PV, Grid and Load figures look correct in iSolarCloud?

[gservat]

I think this is saying I'm producing (and consuming) 3595W but also drawing in 242W from the grid (total of 3837W being consumed).

[bohdan-s]

@gservat i think you are right, I think the load should be 3837W instead of 0. Do you have a smart meter installed with the inverter? DTU666 or something usually.

I can set load_power to a formula if 0, that will give the answer, but I wonder if its behind another register...

Can you try level: 3 (everything) and look for export_power and power_meter. These are both undocumented but used in Solariot

[gservat]

@bohdan-s yes, smart meter is installed (not sure which but it's definitely there).

Just bumped level to 3 and I see export_power showing 1590 (I guess this means importing from the grid? as iSolarCloud also shows I'm importing roughly this amount) and power_meter is 0. Full list of registers:

What I also find a bit strange is that pvoutput is showing 0 values for power generated. Shouldn't this data come be in v2 which is mapped to the total_active_power register and has the right info?

API:

        Parameter   Field               Required    Format      Unit    Example     Donation
        v1          Energy Generation   No          number      wh      10000
        v2          Power Generation    No          number      watts   2000
        v3          Energy Consumption  No          number      wh      10000
        v4          Power Consumption   No          number      watts   2000

Config:

      - name: v1    # Energy Generation
        register: daily_power_yields
        multiple: 1000
      - name: v2    # Power Generation
        register: total_active_power
      - name: v4    # Power Consumption
        register: load_power

Notes from API spec: _Power can energy values can be derived from one another. When a system sends only power values v2 and v4 the corresponding energy values are automatically calculated.

Similarly when only energy values v1 and v3 are sent, PVOutput will calculate the average power._

Since you are only sending values for v1 and v2 it can't calculate the values correct.

I have just pushed a commit to add manual_load: True to the config.yaml file. If you set that it will manually calculate the load_power (total_active_power + meter_power).

Let me know if that fixes the issue :)

That looks much better @bohdan-s! Seeing some proper values in pvoutput.org now:

Thanks again for your help!!
