Growatt : 'Export to grid' information missing ?

[MiosDK]

Hi, I have a Growatt 3600 hybrid inverter where I need the information regarding: 'export to grid' is it possible to have this information?

[biemond]

hey, what does this say on yours

    "measure_power.gridoutput": {
      "decimals": 0,
      "title": {
        "en": "Grid output",
        "de": "Netzexport"
      }
    },

    "gridOutputPower": [40, 2, 'UINT32', "Grid Output Power", -1],

[biemond]

or do you mean total of today export.

can you find out what register I need to use for that.?

    },

    "gridOutputPower": [40, 2, 'UINT32', "Grid Output Power", -1],

I dont know to see that ?

[MiosDK]

or do you mean total of today export.

can you find out what register I need to use for that.?

I need the actual export 'up front' not all Day, I should use it regarding, do you know what I Mean? I dont have a register overview, do you know where I can find the register ?

[biemond]

you should have grid output on your device , what device did you choose?

[MiosDK]

you should have grid output on your device , what device did you choose?

This one at the picture, is this the right one ?

I need the actual 'export to grid' readings, so when the battery is 100% and the sun panels is produceing ex. 1200watt and the house is using 600watt the last 600 watt is to be exported to grid, therefor I will start something in the house that will use the the power insted.

[biemond]

I think you can use the TL one. and you send me a diagnostic report. but grid output is the 1

[MiosDK]

I think you can use the TL one. and you send me a diagnostic report. but grid output is the 1

TL is also ok can I see, but there is not more options to this matter, I have tried grid output, its not the one to use in this matter, the name should be 'export to grid' can upload a modbus PDF maybe I can find the correct register ? I can see there is a 'Grid export YIELD' thats the total for the Day, I need this information when it change immediately, do you know what meen ? 😃

[biemond]

when it is not there , I need to calculate it or find the right register. but you can also do this yourself with solar/batt output minus the load.

what is not ok on grid output?

[MiosDK]

what is not ok on grid output?

I got some information that the modbus registre is 122 + 123 can you fix it ?

[biemond]

will check those.

[MiosDK]

will check those.

New picture from the register here :

[biemond]

oh you want a flow trigger action and block total export.

currently I support these periods with grid, load or battery priority https://github.com/biemond/solaredge.modbus/blob/main/drivers/growattwithbatt_tl/driver.flow.compose.json

[biemond]

looks like it I have already have it on the device or as flow actions , else I will enable it https://github.com/biemond/solaredge.modbus/blob/main/drivers/growattwithbatt_tl/device.ts#L80

https://github.com/biemond/solaredge.modbus/blob/main/drivers/growattwithbatt_tl/device.ts#L28

I dont want to Block export but if I let ex. 500watt in export I will start a electric healing element to my heat exchanger to use the export watt...

Is it the same as the picture ? ![Uploading FB_IMG_1716368424589.jpg…]()

[MiosDK]

I dont think the function Is in the flowcard

[biemond]

you are asking with this 122,123 to block export.

current grid output should be ok for that. can you upload the pic on github, not replying on the email.
also send me a diagnostic report.

The "only" thing I want, is to see the output mesuring of the 'export to grid' so when its in +xxx watt to grid I want to start my electric device to use the xxx watt in the house and when the export of xxx watt is lens ex. 200watt I want to stop my device to use energy in the house.

I dont know how to send a diagnostic report?

[biemond]

from the solaredge homey app settings you can do this.

[MiosDK]

from the solaredge homey app settings you can do this.

I cant find any settings for that, is it possible that you can point out witch one to use ?

[biemond]

I got the developer version but like this on my app

[MiosDK]

I got the developer version but like this on my app

SMPL ?

[biemond]

yeah select my app and press Create Diagonistic report button

[MiosDK]

yeah select my app and press Create Diagonistic report button

Ahh Done, I have called it MiosDK-2024 -> 33a7c675-cb4f-4d9b-93d5-0f5428f0b22a

[MiosDK]

Do you think its possible eith this as I wrote before ? I think the modbus register I wrote before isnt the right one ?

"The "only" thing I want, is to see the output mesuring of the 'export to grid' so when its in +xxx watt to grid I want to start my electric device to use the xxx watt in the house and when the export of xxx watt is lens ex. 200watt I want to stop my device to use energy in the house."

[MiosDK]

I have this Programmed in the the Growatt inverter - but I want this in Homey instead - Maybe it can help you in this matter and you can find it in the Modbus registre :

New report send - MiosDK-2024 - 2 - a19b31e1-2393-48d2-b3e9-8e3a4a4b4c54

here is the output to grid as you can see on the picture 1,30KW - can you see this parameter in the rapport ?

so you can use grid power, but always do 5 min average else it will be on / off every few seconds

[MiosDK]

I dont think that Gridpower is the solution for this, right now I do not export anything because the sun isnt there any more, I have not at view hvor there is 0 KW - right now GRID output is 931W that is what the house is using (the same as Houseload ) and have nothing with export to Grid - is it possible there is another modbus protocol that can be used ?

[biemond]

gridOutputPower should be and it is working for others , not grid power, that is now your batt discharge

[MiosDK]

gridOutputPower

I can not see gridOutputPower anywhere in the app - I have tried to find gridOutputPower text in both Growatt ?

[biemond]

it is this 1 "measure_power.gridoutput": { "decimals": 0, "title": { "en": "Grid output", "de": "Netzexport" } },

[MiosDK]

it is this 1 "measure_power.gridoutput": { "decimals": 0, "title": { "en": "Grid output", "de": "Netzexport" } },

Ok, but right now I do not export anything but using power from grid (see pic) and that is what Grid output is showing and not export from sun to grid ?

[biemond]

yeah, I see it. more as load. It works on someone else as expected. looks your meters are not installed correctly , let check on someone else also.

[biemond]

[MiosDK]

Is it possible there is a difference in witch country the Growatt os placed ? I have the SPH3600 hybrid inverter and a summation meter from electric vendor + smartmeter from Growatt. Do you know if there is others from Denmark there have this solution ? As you can see on this picture, it seems that the import is 0,5 kw, in Homey I think 0,5 kw= bat power + import from grid. Maybe the summation meter is doing something in this matter ? The weird thing in this matter that I can do a programming in Growatt app. To do something when sun is exporting to grid with XX watt and shopping again depent how lens Watt is, I think the information is the same in the modbus ?

[biemond]

solar power is pv - batt charge or batt discharge

batt discharge is your solar/batt . grid output is + for I think it is import.
load is both combined here

can you check insights if grid output goes negative with a load of sun and a full batt. I think negative is export.

[MiosDK]

What about this mesurering on L1 / Grid output current is this in watt or kw, is it possible that this one is mesuring the output to Grid ?

[biemond]

can you show me your insights graphs for the last 7 days about grid output. I think sometimes it goes negative . which means export, pos = import

[MiosDK]

batt discharge is your solar/batt . grid output is + for I think it is import. load is both combined here

The grid is not going negative as you can see at the pic

[MiosDK]

can you show me your insights graphs for the last 7 days about grid output. I think sometimes it goes negative . which means export, pos = import

I have only had this in 3 days but there is no negative graphs

[biemond]

no clue, I just pass it on , let me vpn in to some growatt and see if I see the same.

Ok perfect, let me know if I can do.something more in this matter 👍

[biemond]

you are on the latest firmware or not?
