I do wonder how much it would cost to build a code-compliant, UL-certified/listed system for home battery backup at 50 kwh, with a system that knows to balance things between cells over many charge/discharge cycles.
I gotta imagine a lot of the value add of the established names is that they actually operate in the U.S. (even though all 3 companies I named are Chinese owned). That's not just about marketing (even if it is true that having U.S. operations helps significantly with marketing), but the cost of certifying for different third party safety standards, and having assets/operations that bring them within reach of U.S. courts and regulators.
