Setup integration on home assistant and getting errors:

unrecognized inverter type - serial number : MC210TI839XXXX

(last for digits replaced with X)

Inverter Solax X3-MIC-G2, connected by Waveshare RS232/485/422 TO POE ETH (B)

[KestasG]

After adding serial number to determineInverterType() it started working, all values got populated except Measured Power L1,L2,L3.

[wills106]

Did you include the X3 at the end? Should look like:

elif seriesnumber.startswith('MC210T'):  invertertype = MIC | GEN2 | X3

[KestasG]

Yes, I did. It gets other metrics for all phases, but not power:

Hi,

The inverter is recognized by the integration, but I have the same issue regarding the Measured Power L1,L2,L3 sensors, they report 0. All other sensors are OK as shown by @KestasG

HA version: 2023.7.1 Integration version: 2023.06.8 Inverter: Solax X3-MIC G2 Inverter S/N: MC210T Interface: RS485 / USB adapter - FT232RL

[wills106]

I have just released 2023.08.4b1 I have moved "Measured Power L1,L2,L3" to a different set of registers which could provide the values? I have also added in the extra registers for the Modbus Power Meter.

[wills106]

@KestasG @lcintrat Have either of you managed to test out the Beta? Just wondering if I can release it as a stable release or not?

[KestasG]

Installed the beta, but the sun is already down. Will check the readings in the morning.

[KestasG]

Unfortunately, L1, L2, L3 power is still zero.

[wills106]

Might be a daft question but do you actually have CT Clamps or a Modbus Power Meter connected to your Inverter? Also did you restart HA after updating through HACS?

The reason being is I have feed back from another user who has working L2 and L3, but having issues with L1 at the moment.

[lcintrat]

I have the same results, beta is correctly loaded

But measured values are still 0.

No power meter nor CT clamps connected to the inverter.

[wills106]

If you don't have CT Clamps or a Modbus Meter connected these sensors won't return anything.

[lcintrat]

Oh OK Thank you for your help!

[wills106]

@KestasG do you have CT Clamp's or a Modbus Power Meter attached to your Inverter? If you don't I'll close this issue down as these Measured Power sensors rely on them.

[KestasG]

I don't have a power meter connected to the inverter. I'm just wondering how Solax shows separate phase power on their web site:

[cleveHEX]

That's probably just power it sends to you. This can be closed then?
