Installing a Tesla Power Wall 3 in a Light Well

[bwurz]

Hi All,

We plan to install a Power Wall 3 in an open-air light well that is 4'x12' and two stories high in our home in San Francisco. My questions are:

1. What size does the door accessing the light well from the garage need to be for building codes or fire safety?
2. Does the door need to be fire-rated?
3. Does the door need to have an automatic closure mechanism?

Thank you for your help!

Does the fire department have to approve the location? Is the location in direct sunlight? I am not aware of any requirements for the door.

This page from the SF fire department addresses this topic. I didn't digest it all to see if it answers the specific questions.
