Version V551

Version V551 installed yesterday, system pumps power all day long, out through L1 and in through L2 and L3. D-ESS predictions are no longer executed. Grid disconnected to give the installation some rest....

Did you reapply the config?

Why did you update to 551? Changing versions to the latest for no reason can invite problems.

Don't update unless you need new functionality or a documented fix.

Rollback to the older version.

Just download the older file from professional.victronenergy.com and update it using the "manual file" option. Reapply config.

Quite easy,

There have been some reports of issues with 551, would suggest you hold of on it for now.
