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…

i have downgrade my solar edge firmware to 4.21.23 and al is working at the moment. No communication failure any more.

Hi there, my new SE3000 HW with 4.24.22 Firmware and Cerbo GC 3.72 was surprisingly working stable for 18 days - but failed this morning (see screenshot of my VRM Portal with no data of today): [grafik] So I will request for SE SW downgrade as this worked fine for several months with my previous…

Yes Martijn, I understand that you focus on the differences. Thing is, this one is obvious, the “Dynamic Power limit”. But there will be many differences to look at, for example: - I understood that other updates have been made to the Sunspec implementation by Victron. This was also relat…

[image] Bertus: The old user interface uses less performance Not entirely accurate. If the cerbo is overloaded, the advanced widget - dbus round trip time - will show high latency. If it does not, then cerbo resources are not an issue. On the new UI you can also disable animations which wil…

Thanks Bertus for your help. I maintain two Victron installations and have multiple CerboGX devices. 1 test Raspberry-Pi (beta firmware) and Two official CerboGX devices. Two systems (CerboGX and RP) are up-to-date to the latest VenusOS firmware and one CerboGX (with SE Inverters) is “stuck” to 3…

[image] PV dynamic power limit 0W Venus OS v3.60 DESS I have been running some tests and noticed that, occasionally, the Modbus-TCP communication between the Cerbo GX and the Envoy fails. It can only be resolved by resetting the Envoy. This has happened a coupl…

I use VenusOS v3.72 with an SE3000 from 2014 which is running firmware version 3.2537 and have no issues with the communication other than that the SolarEdge disconnects once per day in the evening and the Cerbo then reconnects after 5 seconds. But the Cerbo connects to the SolarEdge via a multithre…

Do you have some link or info how to set-up/configure such modbus proxy?

I had this same very issue with two SolarEdge inverters. I ditched the modbus solution and just installed two VM-3P75CT energy meters to have relyable data. For the dynamic powerlimiting i just added some Shelly 1 mini to the RRCR in the SolarEdge. Sadly cost a bit of money but saves a lot of hasl…

Hey, I have the same issue here. Asked for a downgrade yesterday… This morning I saw there is a new update available (4.24. 25). Anyone already on that firmware? Is it finally fixed?

It seems that other inverter brands are having similar issues…
