Well, the point is that there exist now with the Fronius Symo Gen 24 Plus and Kostal PLENTICORE plus two very good 3-phase hybrid inverters. As already mentioned, these two are super efficient and outperform most other models. For more information check the above link to the "Energy-Storage Inspection 2020" comparison.
So for me it's a no-brainer. If you really want a powerful 10kw 3-phase solution, get one of them (@tsllst). While the PLENTICORE plus has some nice features in regard to a multiple-inverter config (currently not fully implemented), the Symo Gen 24 Plus offers a solid 3-phase backup capability.
And regarding the battery technology, - it may be for some hard to accept, but the modular LiFePo4 (lithium iron phosphate) technology is the future in the "fixed place" (non-mobile) sector. According most technical parameters like peak consumption it outperforms Teslas LiCoO2 (lithium cobalt oxide) cells which are used in the Powerwall.
The only disadvantage of the lithium iron phosphate technology is the weight. However, in a "fixed place" application like a house battery this point isn't really important. It can be solved with a modular concept. BYD shows with his "Battery-Box Premium" models how this can be archived.
Thank you @lorn10
I'm not 100% convinced that this is the best solution right now.
I'm looking now for the sonnenBatterie 10 performance and the sonnenProtect 8000.
I find it strange that sonnenbatterie is not in the 2020 comparison. It is a german company.
