i'm mostly thinking of how it works when production is larger than demand in the local circuit. phase imbalances are a bigger deal when the phases are 180° out of sync.
When production is larger than local demand you're feeding in into the power grid. If your meter can ran backwards, then you're saving even more money.
in a normal three-phase system, yes. you just slightly imbalance one phase. but in a split-phase system, backfeeding can move the neutral point.
Just install one on each split phase!
But realistically I'm sure I read you guys have 220v hook ups of certain stuff
i'm not american, but the way their 220v outlets work is by literally bridging two phases.
Most states are limiting balcony solar to 600-1200W, which is only 5-10A at 120V. Not enough to cause problems with imbalanced loads in a home, and most peoples homes aren't terribly well balanced anyways. It all more or less evens out by the time you have 10-20 (or however many - idk, I'm not a lineman) homes on a tranformer.
