In installations that work in isolated mode but with network support, the HUB assistant configured in mode avoid delivering power to the network, historically works perfectly, but with the appearance of the ESS assistant, the HUB assistant has not been updated and is not compatible with firmware updates.
The problem is that the ESS wizard always maintains the connection with the supply network and this in unbalanced three-phase installations generates the problem that the system is continuously delivering / consuming energy from the network.
This in Spain is penalized by what would need to be able to configure a solution similar to the old HUBs, in which the connection to the network was only produced in case of need.
