Combining Victron with Fronius inverter

Copy.
Sounds pretty standard for a system so far. I don't understand if you already have this in place or you need some more items from fronius and batteries? Sounds like this would do exactly what you're trying to to do. Is the victron cheaper or something?

Ok . If you say so.

The Fronius battery combo is already in place, I was thinking of the Victron as an add on, to supplement and recover instead of feed back to the grid, some of the extra energy I am producing.

But I have to have the Fronius on the Acin do you think that this is possible ?

You don't have the fronius on the ac in. The ac in of the victron would connect to the grid in parallel-the same grid the fronius is connected to

The fronius would keep doing it's thing, unaware of the victron, and the victron would do it's thing, unaware of the fronius.

The victron will use current transformers. If it sees current being pushed back to the grid, it charges the battery. If it sees a load on the line, it discharges the batteries, it's that simple-in theory at least

Hope it's ok to resurrect this thread.

Here in upstate NY there are plans afoot to get rid of net metering and go to some other complicated calculation that will basically be worse. Right now one can choose to opt in to the worse plan, but it seems like inevitable all new install will be forced to that.

I am assembling an off grid 48V Victron system. My thought is seperate from that, get a small Fronius grid tied inverter, throw some panels on it, no problems with UL listing and approvals etc. Then I can build up credits with net metering that I'll need during the winter months. And then post inspection, connect the Fronius and the Quattro with a Cerbo gx, looks like Fronius and Victron work pretty seamlessly together, and then be able to use the batteries connected to the Victron, while the Fronius remains battery free.

Looks like the Fronius Primo UL would be the one to get for US 120V?
