Section 3: Location and Compliance

Location and Clearances

PWRcell IR (Indoor Rated Model)

Install the PWRcell Battery in dwelling units in the follow-
ing permitted locations only:
•
Attached garages separated from dwelling unit
habitable spaces in accordance with local building
Code.
•
Detached garages and accessory structures.
•
Utility closets and storage or utility spaces.
•
Basements.
•
Other locations not categorized as habitable space
in a dwelling unit.
NOTE: Refer to the local Building Code for permitted
locations for commercial installations.
When selecting a location, consider the following:
•
Install in indoor locations only.
•
If the room or space where the battery is to be
installed is not finished, the wall and ceilings of the
room or space shall be protected in accordance
with local building or fire codes.
•
Install only in clean, dry locations.
•
Do not allow bottom or front vents to become
blocked.
•
See 3-1. Ensure minimum clearances are
Table
met.
•
Multiple battery units must be separated by mini-
mum 3 ft (91.44 cm) between the units per NFPA
855.
NOTE: The PWRcell Battery uses the surrounding ambi-
ent air for cooling purposes. Inadequate airflow can
cause the PWRcell Battery to derate its power import and
export for thermal management. If power derating is
insufficient, due to an abnormally high ambient operating
temperature, the battery will disconnect and enter a pro-
tective error state, requiring manual intervention to recon-
nect once temperatures cool. The PWRcell Battery does
not require the installation and use of an external ventila-
tion system.
•
The battery installation location must meet the
working space requirements in NEC Article 110.26.
•
If installed in a garage or other location where the
battery could be damaged by a vehicle, the battery
must be protected by approved barriers that are
installed in accordance with local building code.
NOTE: The installation and use of smoke or heat detec-
tors within areas of the dwelling unit or attached garage
where the PWRcell Battery is installed is suggested
where not required by the locally adopted building code.

Do not expose the battery to extreme tempera-
tures. See Specifications
acceptable operating temperatures. Operating the
battery outside of the recommended range may
degrade performance.
NOTE: Consider year-round temperature extremes
when choosing a location. In extreme climates, always
install the battery in a conditioned space. Generac rec-
ommends installing the battery in a conditioned space
regardless of climate.

PWRcell OR (Outdoor Model)

The Generac PWRcell OR (outdoor) model battery may
be located in the same locations as the IR (indoor)
model, and also in suitable exterior locations, in
accordance with these instructions and applicable local
and national codes.
When selecting a location, consider the following:
•

ational vehicles or equipment, livestock, pedestri-
ans, or other activity may occur.
•
This equipment is not suitable for installations out-
doors in a marine environment.
•
Do not install where irrigation systems or other
equipment will spray water onto unit.
•
Install only to flat, plumb (vertical) walls on sturdy,
structurally-sound buildings. Do not install on
mobile homes or small, lightweight, temporary, or
portable buildings that could blow over in the wind.
•
Do not attempt to support the unit on soft, deform-
able surfaces or surfaces prone to move due to
frost activity or subsidence. Use the included foot
bracket assembly instead.
•
Do not install where leaves, snow, dirt, sand, or
other debris may block the air intake at the base of
the unit.
•
Do not install where grass, vines, ivy, landscape
plantings, or other vegetation may obscure access,
