Fronius Ohmpilot in a Victron environment

Hello

I am rather new to Victron and a young user of Victron. Have my setup at home gathering everything together.
3 x Multiplus II 5000
1x MPPT RS 450/200
1x Cerbo GX
and a Modbus EM24 Smartmeter

My main question is I would love to use the Ohmpilot to heat up my boiler. But the question is if I somehow get this setup going via Modbus on the Cerbo GX. Or if I need something else to get it going.
Your help is very much appreciated. Many thanks, patrik

I have been discussing the same question with a victron supplier and you can use an ohmpilot in a grid attached setup because it works by the meter telling the ohmpilot what is being fed back, it won't work for off grid.
I was advised to use a MY-PV AC Thor which detects frequency shifting for off grid.

Hi

Thank you for your answer. Does that mean you need the Fronius Smartmeter?
I have a Grid Attached setup.

I just read several threads telling me that My-PV AC Thor does not work as good as Ohmpilot. I dont know. Just reading all and all.

So in fact - how does the setup look like in this case? Ohmpilot, Fronius Smart Meter and all you need to do is connect Ohmpilot with the Smart meter?

Yes you need the Fronius smart meter.

It did seem to be a fairly decent solution.

I can also confirm...My_PV AC-Thor works better in a Victron system... I'm using the single phase version, 3kW
