Hello,
I have three-phase power, but I can’t afford to buy three identical MultiPlus 2s. I already have one. Can it work with two MultiPlus 2s, one on phase 1 and the other on phase 2?
Yes, look at the options in ve.bus system configurator, I think they’re “split phase -120°” and “split phase - 240°” (the latter would be for L1/L3).
It’s easy if you want to run a grid-parallel ESS, that is, everything connected to AC-In on the multis. I had that running for about a month.
If you want to use the AC-Out and ESS, there are obstacles.
Yes it can work exactly as you describe. That is exactly how my system works. It’s brilliant.
