This is a GIANT deal in the appliance space — distribution is the whole ballgame. Market leaders like Zephyr have global showroom footprints and operate sophisticated logistics networks for distribution and repair.
We've spent a ton of effort across hardware and software to deliver active temperature sensing to stoves for the first time -- and this means the top surface of your pan, not some indirect measurement.
Likewise, inverters (how you connect a battery (DC device) to the AC grid, have also been going down in costs (dollars per peak watt), driven by manufacturing volumes and power electronics innovations. 
2) power transistors (what’s needed to power electric motors and convert DC <> AC power) got more power dense and more efficient. Silicon is being displaced by Silicon Carbide and Gallium Nitride. 
This is enabled via a custom, high-discharge 3 kWh LFP battery pack, which we've co-developed with an industry leading partner. We've also developed fully custom power electronics and controls software that are a step above the rest of the industry.
This is equivalent to a residence permit and work permit among other things and allows you to effectively move to Taiwan for up to 3 years without renewal. Fairly sweet program - doesn’t require you to change your job and doesn’t automatically have tax implications.
