Fuji Microinverter 2.2kW is disconnecting

[dcigir]

Description

I have Fuji Microinverter 2.2kW (that's probably Deye SUN-M220G4-EU-Q0) that goes offline (Disconnected) every few minutes.
I also use Fuji String inverter 10kW, with LSW3 logger and that Inverter is working totally fine.
Wifi connection are great as I use Unifi system all over my house. I was using this Microinverter on the previous Solarman Integration from StephanJoubert and I didn't have these issues.

Reproduction Steps

I just added Inverter to the integration.

I see several attempts to read data from your microinverter in the log, but it just doesn't get any response. Is microinverter connected to solarman servers?

[dcigir]

Yes

Could you try to disconnect it from them for couple of hours to check if the issues are caused by saturation?

I had a similar problem with a Sofar HYD 10KTL-3PH inverter, where my LSW3 logger kept disconnecting for some time. Then I got annoyed and connected the LSE3 (LAN) logger to the inverter. Since then I have only had one or two connection failures (usually only 15 seconds).

Hi @vymak, what fw version you are running on your LSE3?

Hi @davidrapan

[davidrapan]

Great, this is the most stable fw to my knowledge. 👍

Still wonder what could possibly cause those few disconnects...
