Is Powerwall necessary in Bay Area?

[Redhill_qik]

I started an order without a power wall in NNV where we don't have a lot of power outages and then out of the blue I got a letter from the power company advising me that they are going to start utilizing brownouts for certain events ie; wind, fire, etc. I have a feeling in the long run as a few have said, I am going to be glad I have it. Peace of mind is part of the ROI to me.

Brownouts, where the voltage dips well below the 120/240V range, is bad and can damage electrical equipment. Your utility like said routing outages or public safety power shutdown (PSPS) when the grid is taken down.
