Which country are you from?
What I read everywhere, there is a shortage of Gen24 inverters. The waiting time for batteries are long as well. The same applies to Enwitec switchover boxes also.
I am disappointed with the Fronius’ capabilities. I think now that is overhyped. A 3 phase inverter is just biggest bullsh!t what they could come up, and nobody tells that all their 3 phase inverters are working as current generators and their meters thinking only that your grid does net consumption measurements. Most countries do not do net. Even you can have a meter from the supplier which does not calculate production/consumption with vector math, but it does algebraic sum for import and export separately.
If your grid does not count with net consumption and your meter is not vector sum, but algebraic then it is going to be a lot of wasted production for the suppliers’s advantage.
The other thing, these inverters are compatible only with BYD batteries. Not even any other single brand. As supply is low, it makes hard to find the battery, or you might have to wait a year for it.
The only one reason why I really regret getting a Fronius Gen24 Plus, is the fact, that Fronius thinks that loads are in a house balanced out. Which will never be the case. The selling phrase of being able to use a water kettle or hob/oven with the inverter in backup mode or from the battery is just poorly misleading.
The 3 phase inverter is a current generator, and outputs the same amount of current to each phase, so there is no unbalanced output. And there is no documentation how much unbalance the inverter can handle. Yes, the single phase backup with the a single socket sounds good, but it is the same as Huawei’s backup box, and having the loads which needs backup placed on the same single phase.
If I would have know before about Sungrow’s inverter and their backup capabilities and compatibility with other battery brands, then I would might go with one of these:

For one single reason:
Provides 100% power to unbalance loads in
backup mode
I am not saying that Fronius is not good, but I am seeing now how they do misadvertise their products and its capabilities.
Just my five cents…
