Hello,

I have a system that worked fine until 1 week ago. Although the batteries are discharged, the 2 Fronius are in throttled status, they are connected on AC OUTPUT of Victron. If i select to "keep batteries charged" the batteries will be charged from the grid without any problem. Also i noticed if the batteries are charged with 20A for example from PV and if i modified "pv feed in excess" to ON, the 2 Fronius will increase their power and all the pv production will go to the batteries/consumption ( from 20A to 80A example). What could be causing this?

dvcc - on

ess: AC feed in excess - OFF.

3 x Multiplus2 5000VA

2 x Fronius

6 x Pytes battery
