UPDATED! SolarEdge Modbus full setup guide with Energy Dashboard integration for Installations with Battery connected

Hello! At first I’d like to thank you for all the time and effort, designing this incredible dashboard!
Unfortunately, I am just starting to integrate this and now I have reached a dead end.
I am struggling with the values I get from the integration or simply the values from the inverter and I don’t know, what ist going here.
I am using the binsentu-Integration and I am able to read the values via Modbus. However, I can’t explain, how to read some of them. For example:
Value via Modbus integration: sensor.solaredge_ac_energy_kwh: 3.866,065 kWh
Value on Inverter Display: 32515 kWh
The value on the Inverter Display should be correct and the value from the modbus integration is far from a realistic value.
These are the entities I use for the Energy-Dashboard, which I assume are correct, the power distribution today the values from the solaredge portal:

Sorry for the weird screenshot, but I am only allowed to upload one media file.
So except for the value “From Grid” all values are differing and I don’t understand, why! I have an SE9K for production and a SE3680 for the battery with a LG RESU10H.
Any ideas? Would be great :). Thx!!

The solar panel entity used in the energy dashboard should be Solar panel production daily according to the guide in the OP.

I wonder if the setup with 2 inverters may also give you different values. I only have one inverter and do not know how 2 inverters would be handled through the modbus integration…

188

@SgtBatten I don’t have that entity available. :frowning:

189

You are right. The integration is only asking the “master”-inverter (battery inverter) which is delivers really weird values. I have no idea, what those values are representing.
So for this to work I’d need to read both inverters which is obviously not possible with the binsentu-integration :frowning:

Maybe this will help, it is a fork from the integration enabling multiple inverters as well apparently. Haven’t tried it myself though

191

Thank you so much!! The fork is working now and the values are correct. Now I can go on and see how to integrate your custom dashboard :slight_smile:

You just add both inverters :wink:
I use the original integration with 2 inverters, each having an LG Battery.

BTW: the dashboard looks awesome, I’ll also take a look into it !

Hi may I ask how you get the flow lines between solar/grid/home seperated from eachother? For me they all show together.

I use a fork of the Tesla style card:

Hey Remko,

i have watched the values about a week now and i’m pretty sure, that there must be an isse. I understand your argumentation, but something must be “not OK”.

Please look at my Screenshots. Both are from the same time and this would only occur, if the House consumes most of the Power from the Battery and - this is since you changed the behavior of the house consumption.

Many thanks. Working now.
It’s a welcome small addition :grin:

197

I do see a similar difference and in my case I can explain it with the battery effectiveness. Could you check the value of that sensor when you have this situation?

198

Which Sensor do you explicit mean?

I can say, that 168w @House Consumption must be wrong. In my case 1 Rack (POE Switch, Server, …) run 24/7 which constant uses about 170w or more.

sensor.solar_battery_effectiveness

That sensor

Homeasisstant complaints that it cant find /config/energy.yaml. Is it possible that i need to provide the path?

Hi Remko,
at the moment i can’t reproduce the previus situations and values. But i’m still investigating :slight_smile:

I have another question - it seems, that the binsentu modbus implementation is not under development. Are you planning to migrate to e.g

it has some good new features (e.g. to close the modbus session after getting the values…) look at:

Greetings,

regarding the difference between App and own tracking:

I have a setup with grafana (for dashboard), postgres (as db) and a node application for accumulating energy values between data points and storing the data.
My modbus update interval is 5s but I have had a difference of roughly 7%. Now I added some protection against those 0 values as mentioned in one of your comments.

Thanks!

I just got a solaredge. And know you are on amber…Are you able to limit export through HA? For when amber fit goes negative
