How to set up ESS with Enphase on Multiplus2 outlet with the new off grid software.

We have a Victron Multiplus2 10Kw and 30Kw Victron Lithium battery's and GX control panel.

On the roof 22 IQ7 micro inverters on 22 panels of 450 W.

Uploaded the new Enphase software Offgrid-0.98 UE Victron.

And now connected to the outlet of the multiplus2, with the MK3 updated the ESS and modified the settings.

Now when I have a grid failure they stop producing and the inverter has to provide the power until the grid comes back. What did I mis?

Is your PV connected to the AC 2 output by chance? By default, that output is only active when grid power is available.

Hello thank you for your interest, but no it is connected to critical loads.

The frequency I can measure is around 75Hz. from the pv the outlet from the multi is 50Hz.
