question

Ok, I wrote the question to fast. I found on the internet, that its possible to run a system with the Fronius Primo on the 120/240V splitphase on 60Hz.


Suppose I will build a 120/240V split phase system combining Fronius and quattros (mix of Grid-tie and Offgrid), does anyone have experience with it?

Recommendations?
Thank you!

You can.

You need the Victron inverters to generate the 120/240V and the Fronius run at 240V 60hz.
You only need a quattro if you want Generator and Grid, Multiplus-II works great if you only need one input.
You have use 2x 120V inverter or 1x 240V inverter with an autotransformer depending on your needs to make the split phase.

Thanks, Shane.
Yes, I now the difference between Quattro and Multiplus.

As you know I am planing a system to run a wooden drychamber. We are thinking at the moment to start the project just with a feed-in system (only Fronius) and maybe later adding a Victron system. If I understood it right, we would need add later a small array with an MPPT, and we have to take care, the 1:1 rule regarding AC coupling vs. Inverter power.
The reason is just the money. The drychamber needs permanently 11kW. So we would need a lot of batteries. Furthermore the devices in the wooden workshop also need power. So we noticed that we would need 4x10kW quattros (split phase and parallel).
All together it is a lot of money at once...

Buliding intially a feed in system, and later swap to a Victron system is at the moment the solution we think about.
