Hi, Recently did a reconfiguration of a SolarEdge SE2200H for a customer to enable modbus tcp and the sunspec protocol. (solaredge was updated to the latest firmware also) The cerbo gx did find the inverter but the communication seems very unstable. Every few minutes, sometimes seconds the communi…

It happens to me every 24 hours… a reboot has always helped so far. Modell SE17K DSP1:1.13.2405 DSP2:2.19.2001 DSP3:NA CPU-Version:4.24.22

Dear @iburger Many thanks for your answer. I’ve tried 3.80~4 and unfortunately it’s not better at all. :cry: with SE FW 4.24.22. (Cerbo reboot many times per day necessary) Edit: 16.03.2026: since a few days I’ve now running SE10K-RWS with SE FW 4.22.44 and Victron OS V3.80~4 and it is really bet…

In my case I have lost two SolarEdge inverters in the last couple of years, they are covered but the first one took nearly 3 months of summer to get a replacement and then I had to pay half a day’s labour to get it swapped out. When the second one failed I took the option as we were having roof wor…

Good afternoon, colleagues. I see there’s new firmware for my SE17K on the official website - 4.24.9. I’m keeping an eye on this thread because I also have a Solaredge paired with a Victron and I’m also experiencing connection drops between the devices. Has anyone installed 4.24.9? Or what is th…

Actually my Solaredge inverters are not connected over RS485 but over TCP. See the attached screenshots [Schermafbeelding 2026-03-17 om 14.56.16] [Schermafbeelding 2026-03-17 om 14.55.41] [Schermafbeelding 2026-03-17 om 14.55.56] [Schermafbeelding 2026-03-17 om 14.55.30]

Yes that’s correct but when you configure the Solaredge you assign rs485 1 as modbus as per the documents in Victron

There is a known bug in the Solaredge inverters with the firmware after 4.22.44. So if a later firmware is installed this behaviour is possble if you use modbus over TCP/IP. Ask Solaredge to downgrade the firmware is the solution. Don’t know if a direct RS485 connection would solve this as well (in …

any news on venus os 3.71? is this problem still present or was victron able to find a workaround?

Problem is still present for me on 3.71. Only solution is a downgrade of the solaredge firmware.
