The battery is placed outside your house near your meter. The right configuration depends on your home’s layout, energy needs, and space availability (see NEC requirements below).
We have 3 main battery configurations:
Wall-mounted battery (20 kWh): 58.5" tall x 27.17" wide.
Ground-mounted battery (25 kWh): (1) 4' tall cube with a 3'x3' base.
Two ground mounted batteries (50 kWh): (2) 4' tall cubes with 3'x3' bases, 3' apart from each other.
You can compare the Base systems more in-depth here.
