I have the same issue with my Growatt SPH 6000TL3 BH-UP

wills106 commented 6 months ago

If you edit: "AC Power to Grid L1" "AC Power to Grid L2" "AC Power to Grid L3" "House Load L1" "House Load L2" "House Load L3"

Replacing unit = REGISTER_S32 with unit = REGISTER_U32

So https://github.com/wills106/homeassistant-solax-modbus/blob/e4c4f436780009eeb175134f7a19c6905293b68c/custom_components/solax_modbus/plugin_growatt.py#L2667-L2680

Becomes:

    GrowattModbusSensorEntityDescription(
        name = "AC Power to Grid L1",
        key = "ac_power_to_grid_l1",
        native_unit_of_measurement = UnitOfPower.WATT,
        device_class = SensorDeviceClass.POWER,
        state_class = SensorStateClass.MEASUREMENT,
        register = 1023,
        register_type = REG_INPUT,
        unit = REGISTER_U32,
        scale = 0.1,
        rounding = 1,
        allowedtypes = GEN | GEN2 | X3,
        icon = "mdi:home",
    ),

Do they return correct values?

Hi!

No, still no correct values:

Hi, the same issue with SPH 4000TL3 BH-UP

I would like to see if I can replicate your problems - but at the moment I am unable to get data into the system. Would you mind sharing your setup parameters (modbus parameters, solax integration parameters) ?

the-sim87 commented 4 months ago

Hi! My setup: Raspberry-Pi with evcc and RS485 adapter running with these options: baudrate: 9600 and comset: "8N1" evcc is making a modbus-proxy, I am accessing with homeassistent-solax-modbus with TCP, no other options active, everything standard.

a9e78rauijasdf commented 4 months ago

Thank you for replying :-) Im not sure your default parameters/options are the same as mine - would it be possible to post a screenshot of all settings? Can you confirm using pin 4/5 (blue/blue-white) and RS485-3?

the-sim87 commented 4 months ago

Hi! RS485-3 is correct. I use Pin 1 (orange-white) to B and Pin 5 (blue-white) to A. EVCC settings is as here: meters:
