Technology & Safety
Arevon has been working with the Poway Fire Department since March 2022 and has obtained approval on the fire protection design.
Lithium Iron-Phosphate
(LFP) technology
powers the Tesla
Megapack used for the
project. It is notably
safer than other batter
types and Tesla has
used LFP since 2019.
Tesla and Arevon
control room
operators will
continuously
monitor the
project 24/7.
Preliminary sign-off
from Poway and SD
Fire Departments.
Will receive additional
sign-offs prior to
facility entering
operations.
The battery storage
systems contain
protection and control
features, including a
battery management
system that shuts
down when operational
environments are
anything less than
optimal.
