Mine is outside for this very reason. At the time Powerwall2 were the best value/capacity by a country mile, but I didn't trust Musk to not burn my house down. So its outside, with a very large planting trough above it to provide some level of weather shield, and a strategic supply of sharp sand if the powerwall goes full Musk.
