Issues with House Load Display HYD 20 KTL-3PH (LSE-3)

[lowcloud]

Hello everyone,

I’m new to this and currently working with a Sofasolar HYD 20 KTL-3PH (SN: P1, definition: sofar_g3hyd.yaml) and the LSE-3 Logger (FW 1.09). The ha-solarman integration is running stable so far. Now, I’d like to start with a few simple analog display cards, such as one for the current house load in watts.
I suspect that I need to calculate the house load using the following values, as they seem to be the only meaningful and available power metrics:

• Inverter Active Power Load Sys
• Inverter Active Power PCC Total
• Inverter Active Power Output Total

e.g.:

The values Inverter Reactive Power PCC Total and Inverter Reactive Power Load Total EPS etc. always show 0 W.

e.g.:

I’ve created a Template Sensor but I’m not sure if the calculation is correct. The Solarman app reports a different higher value for the current consumption. Here's my current sensor configuration:

template:
- sensor:
      - name: "house load"
        unit_of_measurement: "W"
        state: "{{ states('sensor.inverter_active_power_output_total') | float - states('sensor.inverter_active_power_pcc_total') | float }}"

Does anyone have an idea why there’s a discrepancy between the values, or any tips for calculating and displaying the house load?

Thank you in advance for your help!

Hi @lowcloud, I would think that the Load values ​​should already be the values you are looking for but given the values presented it's rather confusing.

I guess the PCC stands for Point of Common Coupling?

Can you give me screenshots of full sensor list so I can get a better sense of it? Best will be one set of screenshots from the night and one set from the day where there is any value above zero on the PV Power. 😉

Reactive Powers unit is VA and not W so that's incorrect in the profile and why they are all zeroes could be also due to some errors in the file but those values are really not that useful for average user anyway.

I'm honestly so confused and I'm either missing something in regard how is your system connected or there are missing some values.

I'm gonna have to look into the docs for this profile. Also you don't have a battery or it just doesn't read the values?

According different file in this repo (w/ the same registers)

• ActivePower_PCC_Total is Grid Power
• ActivePower_Load_Sys is Load Power

Sorry, I forgot to mention that. Currently, I don’t have a battery yet. The surplus is simply fed into the grid.

Thank you for now!
I’ll try working with these values over the holidays and see what happens with them when I generate a bit more consumption in the house. I assume that later, when the house is normally occupied and the base load is higher, the discrepancy with the Solarman app will likely not be as noticeable.

Best approach is to watch Solarman App for when the data refresh and then in that moment make screenshots of both Solarman App & HA (data and sensors) and compare it that way you will have the most accurate comparison (even so it's not ideal it's the best we can do). 😉

Today I had some sunlight and a bit of load in the house. The screenshots were taken at approximately the same time as much as possible:

So it looks like it does match our guess.
