I've watched videos about them, but the solar company didn't offer that kind of setup. I'm not sure how they would shake out cost-wise in years of ROI, versus a less efficient traditional string inverter.

I've also have three-phase AC at home, and battery storage, so not sure how it would combine with that.

I'd also need to look up installation requirements, particulary how it handles de-energizing the grid side when the power cuts out. My string inverter has current transformers installed at the connection point to the grid, so that it knows when the power goes away.
