Getting consumption power figure?

[cajsoft]

Hi, I'd like to get the self consumption figure from the API but cant seem to find the correct one. I have solis hybrid inverter.

I tried [oneSelf] but it doesnt match the figure in the image below.

thanks
Craig.

Probably you have seen this post, about the Power Used:

#15 (comment)

But I assume you also want to know the battery in/out? So you can compute the self consumption?
From the SolisCloud API I think you should get from /v1/api/inveterDetail: batteryPower

batteryPower= round(inverter_detail['batteryPower'] * 1000)

And there is also bypassLoadPower.
With the other information, including familyLoad, you can compute the self consumption figure?

Just play around, to see if you can come up with the computation to get the above figures.
And if yes, please post your code, so others can also use it.

Hi, thanks for the info, but I dont think that's the correct attributes.. the live consumption figure is generally taken via the CT clamp on the eastron meter. this meter sends consumption data to solis hybrid inverter. This must be able to be pulled from the API as the figure shows on the app and website. This consumption figure has nothing to do with the battery. If battery was removed the figure would still be present as it represents the house load. Will keep digging...

Also not the bypassLoadPower?

[cajsoft]

both figures return 0

[ZuinigeRijder]

Maybe make a screenshot as before and at the same time run the adapted script to see the values:

Add after line 248, just before "if SEND_TO_PVOUTPUT":
[code]
pSum = round(inverter_detail['pSum'] * 1000)
batteryPower = round(inverter_detail['batteryPower'] * 1000)
bypassLoadPower = round(inverter_detail['bypassLoadPower'] * 1000)
familyLoadPower = round(inverter_detail['familyLoadPower'] * 1000)
print(f"hi_res_watthour_today={hi_res_watthour_today}, watt={watt}, pSum={pSum}, familyLoadPower={familyLoadPower}, bypassLoadPower={bypassLoadPower}, batteryPower={batteryPower}")
[/code]

Maybe we can figure out the pieces of the puzzle.

[cajsoft]

ok will try this shortly and post back :)

[cajsoft]

seems pSum is not valid.

[ZuinigeRijder]

Ah, ok. Then let's try to just dump all inverter_detail values.
Instead of the code to add, just uncomment line 201 and 202 by removing the hash # character.

[code]
json_formatted_str = json.dumps(inverter_detail, indent=2)
print(json_formatted_str)
[/code]

And also make a screenshot at the same time you dump the inverter_details.

Thanks, apparently the documentation of the API is wrong, it should be psum, without capital S.
Unfortunately the grid usage is 0, so I am not sure if below is correct, but you should check when you get power from the grid and when you deliver back to the grid, with above logging. My first guess:

"pac": 2.122,
"pacStr": "kW",
= solar (computed to watt in SolisCloud2PVOutput)

"batteryPower": 1.79,
"batteryPowerStr": "kW",
= battery

"psum": 0.0,
"psumStr": "kW",
= fromgrid?

home usage = fromgrid + battery + solar
           = 0        + 2.122   + 1.79
           = 3.912 kW

Note that fromgrid and battery can be negative, I guess.

[cajsoft]

in the image I sent above, it shows solar generation : 2.121kw and battery pull : 1.571kw.. total 3.692kw

from your explanation above you state it's the opposite way around?

[ZuinigeRijder]

Yeah, I did wrongly reverse the values, solar is 2.122 and battery is 1.79.

[cajsoft]

think I got it..

[ZuinigeRijder]

As stated in my previous post, battery and grid can be negative, so:

home usage = grid + battery + solar
= -1.732 kW + -2.045 kW + 4.152 kW
= 0.375 kW
= 0.375

[cajsoft]

thank you.. I Think I misunderstood your post earlier.. I've created the calculation and will monitor the consumption figure throughout the day.

thanks again for all your help... awesome script !

[ZuinigeRijder]

I am not sure if the grid value is psum or if this is familyLoadPower.
Let me know, after some days, what you came up with, for the home usage, etc. Including your python code changes.
Maybe I can incorporate this then in the SolisCloud2PVOutput script via a configuration.

[cajsoft]

looking good.. had it running for 2 hours and each time the figures match the images.. so all good.

batteryPower= round(inverter_detail['batteryPower'] * 1000)

    print("Batter Pwr: " + str(batteryPower))

    solarGen = round(inverter_detail['pac'] * 1000)

    print("Solar Gen: " + str(solarGen))

    gridPower = round(inverter_detail['psum'] * 1000)                                        

    print("Grid: " + str(gridPower))

    houseCons = (solarGen - gridPower - batteryPower) / 1000

    print("Load: " + str(houseCons))    

[ZuinigeRijder]

@cajsoft I am still puzzled about familyLoadPower. I asked here about the familyLoadPower:

#15 (comment)

Familyload is all power consumed from all sources

This does not match with your example, where familyLoadPower is:
#24 (reply in thread)

"familyLoadPower": 0.179,
"familyLoadPowerStr": "kW",

This does not match with your values, at least I do not see it.

[ZuinigeRijder]

@cajsoft the new version should now support your use case using configuration. Maybe you can test if this is working for you? Especially because I do not have a solis monitoring solution installation.
