Although TESLA promised to deliver a 3-phase Powerwall in July last year, they could only provide a single-phase version. Promises to have it by end of 2017 also failed, still nothing has happened.
After waiting for more then 1 year it seems TESLA is not going to offer the 3-phase Powerwall in Portugal anytime soon. What is the problem?
Most households in Portugal have a 3-phase grid connection to get enough supply from EDP, divided over those 3 phases. A single-phase Powerwall will only harvest 1/3 of the surplus PV production and only feed that 1 phase it is connected to.
In other words it is very inefficient to use it in a 3-phase grid. Also their built-in inverter is not approved in Portugal yet.
Most European countries invested a lot to upgrade their electricity grid, which results in a much easier single-phase grid.
What is the Solution?
