Hi,
I made firmware upgrate v505 to v507 (2623507)
After that ESS installation fails and any ESS settings not visible on cerbo gx.
Error message: “Cannot determine assistant setup because not all assistants are configured yet”.
How can i overcome this problem? VE Flash?
NickDB, thanks for the info above but it didn't lead to a solution.
The problem came from the capacity of the PV panels in the ESS setup that did not comply with factor 1.0 rule.
The compatibility of the ESS with the new software was not a problem. After adjusting the setting, everything was resolved!
Did you restore the configuration? The process and docs explain that the config is wiped and must be restored as part of the procedure.
How did you update it?
If you mean settings in VE Configure3, then I have restore the configuration.
- I started firmware update via VRM
- after update continued via VE Configure3 settings of each inverter separately
And this stage the error mentioned above occured on one of the inverter.
I can get the ESS settings for two inverters, but not for one and the cerbo ESS menu is empty…
This is three phase system.
I can take a look at your config file of your Multiplus if you like. I have done the update successful just yesterday for my system.
I have sent a request for VRM access.
