@Rocky_H Porsche seems to have with their destination charging program a high-end variant which is open to ALL (type 2) vehicles. (Source: Porsche Destination Charging) Yes, of course, they are standing with this "project" just at the very beginning. And furthermore this charging program is...

Okay folks, - here follows my little contribution to that topic. ;) The answer to the original question "Reporting of a Destination Charger Failure" (asked by @Corazon) is simple. It is effectively the Tesla driver / owner with his Tesla app which has the only reliable option in reporting a...

I also don't know the reason why sonnenbatterie isn't listed at the current 2020 "Energy-Storage Inspection" of HTW Berlin. Maybe this is because their current models are simply not "efficient" enough to get a good ranking... ;) So the company decided to not participate in that "contest". Well...

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...

It's time for a new little update regarding this 3-phase topic. Fronius has announced recently their new Symo Gen 24 Plus 3-phase inverter line which seems to be the new efficiency champion. :) It outperforms the previously mentioned (also quite efficient) Kostal PLENTICORE plus inverters...

Here follows again a little addition to that topic. ;) The Kostal PLENTICORE plus inverters seems to be also a really nice DC-coupled, 3-phase AC solution. They are since a while also compatible withe the BYD HV batteries. These inverters are avaiable up to 10 kW (!) and include 3 MPP tracker...

Here follows a short addition, - the Fronius / BYD package is now officially announced (and supported) also for Australia: BYD Battery-Box HV I know, New Zealand is not Australia but these two are somewhat nearer than Europe. ;) Alternatively it seems to be possible to buy the Fronius Symo...

In Europe, the prices excluding VAT in € are approximately: - €2200 for the Fronius Symo Hybrid 5.0-3-S hybrid inverter - €5600 for the BYD B-Box H 11.5 kWh solar battery So this will give a total of around €13400 for two batteries and the inverter. The interesting on this Fronius - BYD...

Okay Folks, There exist since April of this year from Fronius and BYD an officially approved three-phase AC, high-voltage DC package. This quite interesting single-inverter solution includes also backup and basic off grid functionality. The BYD battery is based on lithium iron phosphate LiFePO4...

Thanks @JohanM for the hint regarding the SMA Sunny Island inverters. :) It seems that since the beginning of this year 2019 there can be configured in conjunction with the LG Chem RESU 13 some quite interesting topologies. For example, - theoretically it should be possible to set up the...

Okay folks, - I can confirm for Switzerland that near every more recent house or building has definitively a 3-phase service available "to the end-customer". It is used usually for devices with heavy power consumption like an oven. A normal one-family house has usually also one 400V/16A CEE plug...

This is really a super interesting topic, - many thanks to all for these information. I can now add here a further little "rumor". Regarding the Swiss market there could exist the possibility that Tesla will introduce in conjunction with it's Tesla Solar Roof also the DC version of the...
