Deye inverters in parallel

[zkrige]

I have 2 x 8kw Deye inverters and 2 data loggers. Is there a way to consolidate the data from multiple loggers ?

[moreje]

you can build your own sensors templates that add them together

Sure but the production data exposed in the solarman up is already the sum, so you sure we need the sum?

you can get both data in Home Assistant? I am able to get only from one instance (Master with inverter_mb_slaveid value 1) , the second I receive all UNKNOWN values (I tried to put inverter_mb_slaveid to 2 and also to 1) ...?

@Klagio were you able to fix this issue? I am facing the same.

hi there. i have the same problem. does anyone have a different solution?

Hi @branteforest, the problem can be solved by using a custom yaml file that contains updated registers for DEYE 12KW inverters.

Check this

Hi, did anyone manage to find a solution for having multiple inverters in parallel?

[Smiley-Ret]

I want to add a second Deye inverter to Homeassistant, that is functioning in parallel with the first, but ADD / configuring the second inverter on Solarman does not work. All the entities are unavailable in the second configuration.

Physically the two inverters and dataloggers are active on the Solarman app, and show current data.

How can I configure both DEYE 5kW inverters into Homeassistant under the community's add on for Solarman?

PS: Both have fixed IPs

Bump, I have the same issue.

I have running 2x 12K-SG04LP3-EU in parallel (one is master with mb address 01, second one is slave with mb address 02). Both are also shown in the Solarman App, both loggers are working. Both have a fixed IP address. I can reach both via the web UI.

But also only the first one works for me in Home Assistant. Both have the same configuration (deye_sg04lp3.yaml) when adding, I tried different mb addresses for the second one, no luck.

Hi, I tried all I could think of, but in the end, I deleted the solarman integration , restarted Homeassistant and loaded solarman again.

[Smiley-Ret]

After that, I was able to load both and works fine for the the period til now.

@Smiley-Ret Nice, do you mind sharing what configurations you have on your inverters and the solarman integration? Like the modbus master or slave, and which modbus address you gave them.

[Smiley-Ret]

I used the power flow card from slipx06, https://slipx06.github.io/sunsynk-power-flow-card/index.html. I spent some time to put the Solarman entities into the card and just read the modbus through the HACS add on. I am still learning, but will tackle direct modbus settings later on. I also used a card for each inverter.

Ok, removing and re-adding everything did not work in my case, but I think found the underlying issue, at least in my case, don't know if its the same for the others.

I checked the logs and found that for the second inverter, no valid battery temperature could be read:

After this, I checked the readings on my inverter itself, and indeed, the second inverter (slave) seems to not get correct battery readings from the BMS. (I have Pytes Batteries with a Pytes Battery HUB, the HUB is only connected to the first (master) inverter)

This is the battery info on the master - correct reading of 24.2°C: This is the battery info on the slave - incorrect / no values:

It shows -100°C on the display, the interesting thing is however, if I query both inverters using only the PySolarmanv5 lib: ` inverterSo = PySolarmanV5("192.168.31.xx", 278267xxxx) inverterSw = PySolarmanV5("192.168.31.xx", 279364xxxx)

print(inverterSo.read_holding_registers(register_addr=586, quantity=1)) print(inverterSw.read_holding_registers(register_addr=586, quantity=1)) `

It gave me the following output: [1242] [0]

The first line is correct, the value needs to be offset by 1000, as defined in the yaml -> this means 24.2 The second line of the slave inverter obviously produces a wrong value.

IMO there should be an option to "allow" false values, or not to discard the whole dataset, so that at least the other values are shown.

@StephanJoubert whats your take on this? Maybe you have an idea? Appreciated.

I have the battery temp problem on both inverters: I did not debug very far on that issue, still one of many little bugs to resolve, but just needed to mention that with that temp, both my inverters still work on home assistant. I have seen screen shots from other people with the -100°C, so it seems to be prevalent.

Here is my Yaml for the master inverter card: I have many custom sensors to produce one card in the end that shows the two Inverter as if one. See next message.

This is my combined card, and my seperate UPS on a Luxpower inverter:

@deuko you can modify the inverter-definition and remove invalidate_all:-line in the battery temperature part (for example via the File Editor):

    - name: "Battery Temperature"
      class: "temperature"
      state_class: "measurement"
      uom: "°C"
      scale: 0.1
      rule: 1
      offset: 1000      
      registers: [0x024A]
      icon: 'mdi:battery'
      validation:
        min: -100
        max: 99
        invalidate_all:
