I just recently installed a single phase system and was very positively surprised. I am now already planning on extending the system. Ideally I want to use a 2-phase system as my loads are also on 2 phases. The official documentation says that 1-phase and 3-phase ESS sytems are supported, but I saw that the VE.bus configurator also supports Dual Phase with 120deg separation. Does this unofficially work with ESS, or is it not supported at all?
It works. But when your Grid is 3-phased, you’ll either need the Splitphase 120 (for L1 and L2) or Splitphase 240 (For L1 and L3)
Well, while beeing Grid connected, the multis will sync with the grid anyway, but having that aligned with the actual phase angle doesn’t hurt - may even be required to successfully resync once grid is restored.
