In three phase ESS systems, when L2 or L3 phases are lost (and L1 is still present) the AC coupled Fronius inverter on AC out will not operate and an error 105 is dispalyed. If L1 phase is lost and the others are present the problem does not appear.
This means that the ESS system will not charge the batteries in a power failure of the grid so the system is useless....
I have contacted Victron support since 2022 but nothing has been done. Another member of the community verified the problem and said that Victron replied that it is not their priority to fix the problem. Fronius support on the other hand has reported immediately that this has to be handled by VIctron.
Please give some attention to the matter. There are many of my clients that complain an say that they paid for a system that is not working when necessary...
