Hello,
“Single-phase Fronius on-grid system coupled with Victron and a 250/100 mppt.”
Today I noticed that if I have the battery at 100% and small consumers in the network, only the Fronius injects and the mppt reduces its production to “0”. If I turn on a large consumer, it starts producing again. Why doesn’t it inject into the network if it’s sunny and drops to zero? Thanks
Hi Grig,
Some of this will depend on the ESS settings and the country code selected for the inverter.
Some more detail on your system and how it is set up might help.
You need to enable DC feed in. The limit is not the problem here.

DC feed is set to excessive. It worked until a few days ago. Could it be because I haven’t updated Quatro for 2 years? (Europe Romania)
thanks
Very possible if you have the gx up to date but not the whole system.
This also depends on the grid code set in the inverter. However if the PV inverter is on AC out, then dc feed in should start working once enabled.
