Battery Capacity wrong #267

Closed tobaco closed 3 months ago

tobaco commented 3 months ago

Describe the bug:

My battery capacity shows a wrong value. It shows 0.0 instead of 9.6

Your Sungrow inverter:

Home Assistant version:

modbus_sungrow.yaml:

Inverter Firmware Status:

Additional context I tried several modbus addresses mentioned in other issues, but nothing showed the correct value (eg. 655).

Here's my current setup (including my tried addresses):

      - name: Battery capacity
        unique_id: sg_battery_capacity
        device_address: !secret sungrow_modbus_slave
        address: 33048 # changed from 33048 to 13038 to 13039 to 33049 to 13038 to 33048 # reg 33049
        input_type: holding # changed from holding to input to holding
        data_type: uint16
        precision: 1
        unit_of_measurement: kWh
        device_class: energy_storage
        scale: 0.01
        scan_interval: 600

can you check this?

I'll try. It's something my solateur has to do. And getting him to react and to do this, will be a challenge. Thanks for the link!

you can also setup a new isolarcloud account with another email adress and register yourself as "installer". Sungrow does not check this (we all did this :) )

Then you can add the plant to you as installer and have complete access to your hardware

tobaco commented 3 months ago

Oh, I didn't knew this. Is my original installer then still in control or will he be out of the system. I don't want to jeopardize my warranty. Thanks!

#88 (comment)

My installer answered me in a record time (😳) and told me, he has corrected the value and also did a firmware update. But the sensor still shows "0,0". I also tried the other modbus addresses, but it only changed to "655".

Is it a big problem if the sensor has an incorrect value? So does that have any effect?

Could I just set it via the developer tools or define it statically somehow? It shouldn't actually change, should it?

Louisbertelsmann commented 3 months ago

The sensor shouldn't change, except when you expand or shrink the battery, e.g. adding or removing a module. If you aren't using the sensor, I don't see why you would want to change it. If you are using it, like for predicting the amount of charge left after a night, you can create a helper to set that capacity.

OK, New Installer Account is created, but how can one add the inverter to the new installer account? If I am trying to add it via it´s serial number that does not work.

Gnarfoz commented 3 months ago

You need to share it from the existing customer account to the new installer account:
