I tried to signup for this program but the building code gets in the way. You need 3' from both edges of the battery to a window or door. I don't have a wall with 8-9' between windows. The alternative is to build a fire proof room in your house which takes up a lot of space. Ultimately it was not worth it even with all the financial incentives. The rules might seem innocuous but they're a dealbreaker. It's far easier to get a propane or diesel generator installed.
I would be much more nervous about a 13+ kWh battery than a natural gas generator.
The generator is generally only risky when in operation. For natural gas units, a normally-closed solenoid keeps the gas off unless the controller actively commands it. A battery is constantly in a state of non zero fire risk when charged.
Generators are generally used outside. There are some rated for use inside, but they also have strict regulations on how that is done. (there are also some used inside but they will kill someone soon)
Maybe where you live, but where I live the temperature outside is bad for batteries.
Though what is "inside" is debatable. My car can sit outside because it has the batteries in a case that is climate controlled when needed, and so the batteries count as inside even though they are in a car that is outside.
