Fronius Primo or GEN24 Primo

I have an off-grid system with Multiplus II 5000, 2 x Pylontech US5000 and smartsolar 250/70 with 3kw PV array.

I want to upgrade my system with a Fronius PV inverter to power my new cooling system during the day.

One of the doubts that I have is to select the right or better single phase Fronius model to be integrated in a VE off-grid system. I see that there are several: Fronius Primo, Fronius Primo UL, Fronius GEN24 Primo,..., but I want to understand that in an off-grid VE system some Fronius festures are useless and some others are mandatory.

What Fronius model fits better in an off-grid Victron Energy system?

Thanks

recommend the Fronius PRIMO with Datacard (not the light version);

the Primo is connected to ACout; grid=MG50;

configure the PV assistant in the MPII;

Observe the 1:1 rule!

isn't there also a cerboGX available?


I have been operating an off-grid system with cerboGX, 2x MPII3000 (in parallel), a Primo6, 8x US2000C and MyPV Thor9s with 6kW heating rod for years ... ... is running perfectly!
