SolarEdge production throttling from Domoticz

[jvdz]

Let's take this offline and use Email for the exchange of information, as else there is no way I can debug this.
I need the capture of the startup of the Plugin on DEBUG level so I can see the received data and what the plugin is trying to do with that data.
Agree and could you perform this for me and send it to me as attachement?

[jvdz]

Are you sure you did a git pull for the Meters2 branch?

Does anybody see any reason why we should leave the Average/Max calculations in there as I would think that domoticz should simply receive the inverter raw/real data?

Absolutely agree. I don't see any need (at least for me).

BTW: I'm am sorry that I can't help currently due to traveling. But I am really happy to see that you are working on it and am really excited. Thank you!

Latest "Meter2" version works nice.
tnx Jos

[jvdz]

Great to hear that all seems to be working.
Now my final/next idea was to use the latest version of solaredge_modbus available on github, which includes a number of extra fields in the Inverter information block: (These are the values I get without Meters/Batteries)

Code: Select all

# ----------- Extra fields with latest commit solaredge_modbus ------------------------
#     "commit_power_control_settings": 0,
#     "restore_power_control_default_settings": 0,
#     "reactive_power_config": 0,
#     "reactive_power_response_time": 200,
#     "advanced_power_control_enable": 1,
#     "export_control_mode": 0,
#     "export_control_limit_mode": 0,
#     "export_control_site_limit": -340282346638528859811704183484516925440,
#     "storage_control_mode": 0,
#     "storage_ac_charge_policy": 1,
#     "storage_ac_charge_limit": 0.0,
#     "storage_backup_reserved_setting": 0.0,
#     "storage_default_mode": 0,
#     "rc_cmd_timeout": 3600,
#     "rc_cmd_mode": 0,
#     "rc_charge_limit": 3300.0,
#     "rc_discharge_limit": 3300.0

The following fields could be of interest, as explained here:
shows/sets the mode the battery operates in as explained here:
storage_control_mode

Code: Select all

STOREDGE_CONTROL_MODE = {
    0: "Disabled",
    1: "Maximize Self Consumption",
    2: "Time of Use",
    3: "Backup Only",
    4: "Remote Control",
}

rc_cmd_mode(Assume this is the field for this)

Code: Select all

STOREDGE_CHARGE_DISCHARGE_MODE = {
    0: "Off",
    1: "Charge from excess PV power only",
    2: "Charge from PV first",
    3: "Charge from PV and AC",
    4: "Maximize export",
    5: "Discharge to match load",
    7: "Maximize self consumption",
}

This one isn't described in the linked page, so not sure what this would give extra
storage_ac_charge_policy

Code: Select all

STOREDGE_AC_CHARGE_POLICY = {
    0: "Disabled",
    1: "Always Allowed",
    2: "Fixed Energy Limit",
    3: "Percent of Production",
}

Is anybody aware of these settings via the SA App or WebSite?
Would it be an idea to add these as a Selector Switch so they can be dynamically be monitored and set from Domoticz?

[imautohuttraeger]

See Screenshot of the Option for Charging attached. And these are the explanations (haven't worked with this for the time being):

Battery Modes Information

Maximize Self Consumption

Go green and use the maximum solar available to power your home, charge your battery and minimize grid import.

Time of Use

We use a smart algorithm to optimize your energy sources based on your consumption habits, current and predicted energy output, and weather forecasts, to reduce your energy bills if you have different rates on different times. During manually configured peak hours or hourly dynamic prices your home is powered by solar as a first choice, by the battery as the second choice and by paid energy from the grid as the last resort.

In addition, based on your utility and installation settings, your battery can be charged from the grid, or energy sold to the grid when export rates are high.

Learn more

Manual Control

This mode allows you to set start and end times for charging and discharging your battery. You can set these schedules be recurring. All other time, the system operates to maximize self-consumption.

When a charging schedule is in place, the battery would charge from solar if available, and from the grid if allowed. Charging stops when the battery is full or when you reach the end time. During that time, the battery would not discharge itself.

When a discharging schedule is in place, the battery would discharge at full capacity, to provide for the home consumption and export energy if allowed. During that time, the battery would not be charged from the grid, it could only be charged from solar if it is available and it is not consumed by the house.

You can set multiplue charging and discharging schedules, as long as they do not overlap.

If you have high export rates at a certain hour, this mode could be utilized for monetization. You should set a charging schedule that ends when the high export rates begins, and set a discharging schedule for that time.

In addition, if you want to charge your EV during low-rate hours and make sure it does not use the battery, you should set a charging schedule for that time and the battery would not discharge itself.

Backup Only

Preserve energy sources and provide you with longer backup coverage time, while automatically reducing consumption to preserve battery energy. With this profile, the system will turn off any non-essential SolarEdge controlled device to preserve battery as outage starts.

Latest "Meter2" version works nice.

Only "Maximum self consumption" and "Backup only" makes sense for a pure selector switch. The othe options deman separate adjustments (see screenshots)

[jvdz]

@imautohuttraeger, did you also read the information of the HA implementation and try to link that with everything you posted here?
It is somewhat difficult for me to interpret the whole setup from screenshots. It sounds to me that the APP will perform the logic for certain selections like you could do as well in Domoticz when you select "Remote Control" as First Mode.
I can make an update available that has the 2 Selector switches with the defined selection options as posted earlier (First 2) so you can have a look.

[eddieb]

In the Solaredge system I am testing is besides an Inverter, 2 meters and 1 battery also a Solaredge device called "Home Load Controller"
that is not found by the plug (yet) ...
would be nice if that one is detected ...

No idea what that is or whether any of the information is available via MODBUS.... BUT let's first finish this part of the development where it should be possible to define how to use the Batteries.

[imautohuttraeger]

@imautohuttraeger, did you also read the information of the HA implementation and try to link that with everything you posted here?

Yes, I had a look on the Batterie section of the Github page you mentioned earlier of the HASS implementation

https://github.com/binsentsu/home-assis ... dge-modbus

Is this what you mean?

Since I don't know much about controlling the battery, because I haven't done anything with it yet, I can't really contribute much.

Most interesting for me would be to have the charge / discharge utility so it can be integrated into Domoticz Energy Dashboard.

That is indeed the site I linked in my post and even the paragraph on this topic.

Don't know what that means. Doesn't the current Meters branch give you the proper device to integrate into the Energy Dashboard? I would expect that there is a Meters Device showing you this info?

[eddieb]

morning, I took the jump and installed latest "Meters2" on my old production domoticz ...
- unable to find the module versions ...
- it detected a "meter" while I am pretty sure there is NO meter ...

@eddieb, could you please set the log level on debugging on the docker version, capture to log generated, and email it as an attachment?
That will enable me to dig into the code why is is doing this.

Thanks jos

[eddieb]

@jvdz in your mail

[imautohuttraeger]

Since you have one you can test/play ...i can't.

You are absolutely correct, I can test it and it would be a pleasure to to so.

My sentence

"I can't really contribute much"

relates to your question

did you also read the information of the HA implementation and try to link that with everything you posted here

So I meant yes, I have read it and have taken it into consideration. But I am just a layman and simple user and don't really understand such technical explanations.

Don't know what that means. Doesn't the current Meters branch give you the proper device to integrate into the Energy Dashboard? I would expect that there is a Meters Device showing you this info?

Oh - this is a misunderstanding. I am talking about the old implementation - I could not install the latest Meters branch. As I formerly wrote, I am currently traveling on the job, so I can't access my RasPi from abroad and free time is very limited. Maybe I can try via VPN this Weekend from the Hotel, but last time I tried it failed (there seems to be a VPN maladjustment in my home router that I can't fix remotely).

Big SORRY for partly wasting your time and that I don't express myself clearly enough while writing on-the-fly. I am so grateful that you are committed to get progress on this.

[jvdz]

No worries... Always appreciate any contribution and express when things aren't clear to me.
