How heavy is your node red load?

I have seen when the cerbo gets hot and then with extra loads on processing, strange things can happen. So you could improve cooling or reduce the node red dashboard and processes. Reduce logging intervals.

The simplest fix which I know you won't want to hear, is get a BMV.

Hi @Alexandra and thank you for your feedback

Don't know where to look at to know my node red load but there are only 2 scripts

- one, that run once every hour to calculate the forecast production

- one that run cyclically to estimate if CVL should be altered between 55.5 or 56.3 (to ensure SOC synchronization) based on 3 values (CVL, SOC and Ubat)

I just checked the Cerbo and it is warm but not hot.

Regarding the fix, I have one simpler that cost nothing : switch off AC-IN.

But this is not really satisfying as it prevents me from injecting the excess AC (I'm not paid for, it's just better for the planet)

One more example of the strange (to stay polite) behavior of my ESS

It is jumping between taking from grid / stopping and even switching off the MPPT instead of switching off the AC-IN intake

But this is useful as it force me to find a workaround and I found a much cheaper option than the suggested BMV, @Alexandra : limiting input current to the minimum allowed : 1A. Like this the ESS can toggle between sources like crazy but at least it will not take several kWh from grid while there is plenty of sun power available

With DVCC on and the battery control the settings on the components would be ignored unless the bms lost connection. But then that would throw up errors anyway.

Yeah the waening would be bescaus your ve config updated, there are new versions of the assistant. There are some improvements in firmware being rolled out for wind and solar priorities.

Possibly updating the all the system components might help? But then could also create other problems.

Yes @Alexandra , this is the main issue when updating a system to the latest version, as old programmers often says, why attempting to fix a fully functioning system.

Should be taught to all those aficionados of google, windows and other modern stuff where their smartphone spend half of the time and takes a quarter of the bandwith to update.

Back to the issue, the latest ESS assistant version is 0184 and I have the 017E, unfortunately the changelog assistant doesn't mention this 0184 version

Could any Victron staff member like you @mvader (Victron Energy) or anyone else update the changelog for assistant with latest changes?
