which product does it all

Tired of not finding a clear answer in de product descriptions. I'm looking for a charger inverter ups-function which will also delivers power to the grid when the batteries are full or not connected. Do all inverters de this? Or none of them? Or did I miss one.

Thanks, Mich

Not sure about the "no battery connected" part but the other is possible with all MultiPlus (+ GX device) with the right configuration.

But you also must have an eye at you local laws and restrictions about that topic.

You should get in touch with a local Victron partner/installer.
He can help you to find the right components for what you want to accomplish.

You need to be more specific, do you want solar PV input fed back to the grid? Without a Battery.

Then the ability to add a battery?

Last year I replaced a stecagrid (blown fet) with a growatt and now it looks like a couple of enphases have given up (red flashing leds). They have barely recovered the cost. So I'm looking for something reliable for all contingencies in one.

So if I understand correctly I can connect a small battery to a multiplus, feed the growatt gridinverter into the multiplus and it should work as I intended?

As long as the growatt supports frequency shit control, also you need to size the battery adequately for the PV size.
