8. Planning installation layout
Planning the installation layout is an important step to make sure the IQ Battery 10C is installed and mounted correctly as per the
specifications.
8.1 Choosing a location for the IQ Battery array
• IQ Battery 10C is NEMA Type 3R rated and can be installed Indoor or outdoor. The terminal
blocks on the IQ Battery 10C accept a maximum conductor size of 3 AWG for L1/L2/N
terminals and 8 AWG for the Ground terminal.
NOTE: Enphase IQ Batteries have been evaluated to UL 9540A standard for outdoor
and non-habitable indoor residential installations. Units are only intended to be installed
in attached or detached garages, sheds, and locations more than 152.4 cm (5 ft) from
dwelling units, and are not intended for installation in habitable spaces and living spaces
in dwelling units.
• Make sure the installed location can sustain the total weight of 318 lb (144 kg) per
IQ Battery 10C. The wall must contain blocked studs that can bear the battery weight or
be made of masonry or other suitable structures.
• When installing on a wooden wall, it is suggested to use a flame-inhibition plate between the
wooden wall and IQ Battery 10C. Consult the regional building regulations for any additional
requirements.
• Make sure there are no pipes or electrical wires where you plan to drill.
• Provide heat or smoke alarms in residence in accordance with building, fire, and installation
codes.
• Follow local standards, choose a non-habitable indoor location (like a 2-car garage) or
an outdoor location where the ambient temperature and humidity are within -4°F to 131°F
(-20°C to 55°C) and 5% to 95% RH, non-condensing. Avoid direct sunlight to ensure the
temperature stays in the optimal operating range. This ensures charging and discharging
currents are not de-rated due to temperature. The full performance will occur within 59°F to
113°F (15°C to 45°C) while charging and within 41°F to 122°F (5°C to 50°C) while discharging.
• Consider the dimensions of the IQ Batteries, easy access, height, and cable length when
selecting the location.
• Select a location where you can easily make wiring connections of the IQ Battery 10C to the
IQ Combiner 6C.
• This product must not be installed at altitudes above 9,842 ft (3,000 m).
• Follow all local standards and regulations set forth by the Authority Having Jurisdiction
(AHJ).
• Up to two IQ Battery 10C units can be daisy-chained on a single branch circuit.
IQ Combiner 6C supports up to a maximum of 80 A breakers for the IQ Battery 10C
connection circuit.
NOTE: Up to four IQ Battery 10C units can be daisy-chained on a single branch circuit
using battery oversubscription PCS. Ensure to add a PCS disclaimer label at all PCS-
enabled IQ Battery 10C units.
• The maximum conductor size for IQ Battery 10C is 3 AWG for L1/ L2/N terminals and 8 AWG
for ground terminals, and the maximum breaker rating with this conductor size is 80 A.
