Fronius battery control?

mstormi · February 13, 2022, 11:41am

Hi,

while I unfortunately don’t own any Fronius inverter myself to tamper with, I’m trying to implement battery control for it.
There’s the powerflowchannelpakku channel to read what’s going into/out of battery but I want to enforce charging or discharging.
The Fronius Modbus document mentions a register ChaGriSet to allow for charging from the grid or not but I have not seen this in the binding.

By chance, has anyone played with or implemented battery control on a Fronius inverter or knows how that would work ? maybe @jimtng ? (sorry for pinging you).

thanks

Unfortunately I don’t have a battery, and only a Fronius Symo inverter, not the Gen24 (Hybrid). If you know the json / API to control this, I’d be happy to add the capability to the binding.

Hi,

I am for the time being setting up a spot market control system for our bigger electrical loads. This will certainly take a while. But after that I would really be intrested in the possibility to set the PV system battery charging from the grid on/off from the same control system using Modbus TCP or RTU. From the inverter webserver it is possible only to set it on or off but no timing is possible as far as I have tested.

Our PV system is all Fronius,

Fronius Symo GEN24 6kW Plus inverter
BYD 10,24kW battery
Ohmpilot
Wattpilot
Smartmeter

The battery grid charging would make it possible to charge the battery at night during the winter when the electricity spot price is low and then discharge at daytime high price period.

At these high energy price times such a solution would certainly interest many PV system owners with a battery.

Are you aware of the commercial energy management system I’m selling ?
It’s now working with Fronius inverters. Just battery control to do peak shaving does not work.
I have an idea what to try but it’s a lot of trial & error because vendor documentation is sparse or unclear. Would you be willing to help with testing ?

ruxu · September 16, 2022, 6:35am

I visited your pages and briefly looked trough them. My German language knowledge is not very fluent so I have to spend a little more time to read all the text. I am living in Finland.

Are Ohmpilot and Wattpilot supported in your system?

It is true that more technical Fronius information is sparse, e.g. I have not been able to find the latest Fronius API document only the previous version. We have a ground heating pump fro a Finnish manufacturer Oilon and there is the same thing - a lot of digital in- and outputs, relay controls - but no documentation and poor technical support.

As I earlier said I am in the very beginning to set up my spot market control for our ground heat pump, water heater, EV charger and hopefully the on/off grid charging of the battery. So at this point I am not able to be involved in testing.

But for the future I am in principle interested in testing when the time is convenient.

Sorry I assumed you’re German because of your name.
I suggest you use Google or DeepL translator.

I don’t know these devices and the current OH Fronius binding does not offer access to these.
So they will continue to operate the way they’re configured now but off the shelf no the EMS cannot address them. However if you and/or I determine how to access them via Modbus (like I do for battery control) it should be simple to control .

Essentially you would only have to setup a box with my EMS (see https://storm.house/installation#demo) and grant me access to your inverter via IP/Modbus.
I’d then access it through VPN and try to get things to work. If you’re proficient with openHAB you can help with and take part in that, if not your part would be just some monitoring tasks.

Meanwhile you can already take advantage of the running EMS. For example if your heat pump has a SGready interface you can connect it and "pre-"charge its heat buffer using excess solar power (which is even cheaper than spot prices are).

I little bit late, reaching this post googling.
Here sbam (Smart Battery Advanced Manager) : GitHub - atbore-phx/sbam: Smart Battery Advanced Manager

Available as Home assistant add-on or stand alone cli.

You Can handle the charge process of your Solar Battery via a Fronius inverter regarding weather forecast and much more…

Hello,

I own a Fronius Sumo Gen24 with a 10.2kw BYD Accu.
I’m trying to use the the inverter actions as described in the docu.

But if I use this in a rule:

val froniusInverterActions = getActions('fronius', 'fronius:powerinverter:mybridge:myinverter')
froniusInverterActions.forceBatteryCharging(Accu_to_charge_amount.state)

I get this in the log and no charging gets startet.

2025-01-17 21:47:19.601 [WARN ] [l.handler.FroniusSymoInverterHandler] - Battery control is not available. Check the bridge configuration.

What is to do in the thing definition / bridge configuration?
Am I missing something?

My thing file is this:

Bridge fronius:bridge:mybridge [hostname="xxx.xxx.xxx.xxx", refreshInterval=15] {
    Thing powerinverter myinverter [deviceId=1]
    Thing meter mymeter [deviceId=0]
}

thaake · January 17, 2025, 9:42pm

I found in the docs the mention, that username and password has to be provided for battery control.
I did that, but no change, still same error.

florian-h05 · January 18, 2025, 8:29am

You might have to disable and enable the inverter Thing again.

thaake · January 18, 2025, 9:09am

Thanks, that was a good advice.
Now I am one step further, but not working till now.
No I get this error in the log:

What is your openHAB version?

Works fine for me with my Symo Gen24. I have developed the battery control by reverse engineering the API calls made by the inverter‘s web UI.

thaake · January 18, 2025, 10:34am

I’m on 4.3.2

florian-h05 · January 18, 2025, 12:32pm

That’s interesting - for me it is working fine.
What is your Fronius inverter model and which firmware version do you use?

I have a Symo Gen24 10.0 with firmware ROW 1.34.6-1 (latest as of today), and it works.

sihui · January 18, 2025, 1:41pm

Same here.
Out of interest (no usecase at the moment) I tried the Thing actions with my system and got the same error message (openHAB 4.3.2):

Edit: I already tried Customer and customer as username which did not work either.
Login to local web ui works fine.

florian-h05 · January 18, 2025, 2:47pm

You can only login as customer or technician with the password you need for the web UI.
Have you double checked the credentialsß?

sihui · January 18, 2025, 2:49pm

Triple checked
I even logged out from the web ui and logged back in to make sure they are correct …

florian-h05 · January 18, 2025, 2:57pm

But why is there xyz@gmx.net as username in the log??
Are you sure you logged in to the inverter? You don’t need Solar Web.
