If you use the Powerwall as a power backup solution, you have to contend with the fact that it does indeed deliver backup power ... Starting about 5-10 seconds after the power goes out. So for certain things that you'd rather not have any power interruption for (like your computer, maybe your network gear), you need a UPS.
The problem with existing UPS is that their lead acid batteries last about 4 years. At which point you've got an expensive and messy upgrade procedure. And the UPS is designed to bridge far more than 20 seconds of downtime. Since lead acid batteries don't deal with rapid deep cycling week, you have to get a reasonably sized one.
So, my thought was, I wonder if there is a market for a super capacitor UPS? IF you could build it out of components that would last 20 years, you could build a fairly small and light unit since it would only need to bridge a 20 seconds power gap in a Powerwall (or any generator) household. Thoughts?
