Are the HUAWEI SUN2000-5KTL-L1 or SMA Sunny Boy 5.0-1AV-41 compatible with a Victron MP2 in off-grid mode?

Hello dear Victron community,
Does anyone know whether the aforementioned HUAWEI SUN2000-5KTL-L1 or SMA Sunny Boy 5.0-1AV-41 support frequency shifting, or whether they can be controlled by the Cerbo / MPII in off-grid mode?
Has anyone integrated such inverters into their system?
They would of course be connected to the AC Out, in case anyone was going to ask.

I have always used Fronius up to now, but I could get inverters like these now.
Yes, the inverters are not approved in Germany; I’m aware of that. (They don’t want 5000 W on a single phase here any more, …

If it complies with VDE-AR-N 4105, that should work.

Please search the forum for HUAWEI SUN2000; I think this question came up recently.

I have a 12 years old SMA SunnyBoy 2.5kW inverter running in an off-grid MP2 system and it does the 52Hz throttling down to zero output. No problems.

Why does it have to comply with VDE?
It’s about an island system, so VDE isn’t necessarily mandatory, is it…?
I couldn’t find anything in the system regarding island systems.

Great, that already helps me make my decision

Because frequency shifting is defined in 4105, just like NA protection.

It would also have been very easy to find with Google.

Yes, that’s what Google says, but since it has 5 kW, it doesn’t comply with 4105 and isn’t approved for use in Germany! That’s why I’m asking the group whether it works in an off-grid system.
