+
DANGER: Risk of re. During use, when stored, or during transport, keep
the IQ Battery(ies) in an area that is well ventilated and protected from the
elements, where the ambient temperature and humidity are within -15° C to
55° C (5° F to 131° F) and 5% to 100% RH, non-condensing, preferably out
of direct sunlight. Do not install the IQ Battery(ies) at elevations over 2500 m
(8,200 feet) above sea level.
+
DANGER: Risk of re. If the IQ Battery(ies) generate smoke, remove AC
power from the Enphase System and turn the DC connect switch to the off
position so that charging/discharging stops.

DANGER: Risk of electric shock. Always de-energize the AC branch circuit
during an emergency and/or before servicing the IQ Battery(ies). Never
disconnect the DC switch under load.
+
DANGER: Risk of electric shock. Risk of high short-circuit current. Observe
the following precautions when working on batteries:

Remove watches, rings, or other metal objects.
•
Use tools with insulated handles.
•
Wear insulating gloves and boots.
•
Do not lay tools or metal parts on top of batteries.

should be in the range of your voice or close enough to come to your aid
when you work with or near electrical equipment.
+
DANGER: Risk of re. Do not allow or place ammable, sparking, or explosive
items near the IQ Battery(ies).
+
DANGER: Risk of electric shock. In areas where ooding is possible, install
the IQ Battery(ies) at a height that prevents water ingress.
+
DANGER: Risk of electric shock. AC voltage is present at the output when the
DC switch is on.
+
DANGER: Risk of electric shock. Branch circuit protection must be off before
switching DC power on or off.
+
DANGER: Risk of electric shock. The DC switch must locked in the OFF
position for shipping and service.
*

not disassemble.
*
WARNING: Risk of equipment damage. During use, storage, transport, or
installation, always keep the IQ Battery(ies) in an upright position.
*
WARNING: You must install the IQ Battery(ies) only on a suitable wall using
an Enphase wall-mount bracket.
*
WARNING: Before installing or using the IQ Battery(ies), read all instructions
and cautionary markings in this guide and on the equipment.
*
WARNING: Do not install or use the IQ Battery(ies) if it has been damaged in
any way.
*
WARNING: Do not exceed the maximum number (3) of IQ Batteries in a 20 A
AC branch circuit.
*
WARNING: Do not sit on, step on, place objects on, or insert objects into the
IQ Battery(ies).

WARNING: Do not place beverages or liquid containers on top of the IQ Bat-
tery(ies). Do not expose the IQ Battery(ies) to liquids or ooding.
*
WARNING: When placing the IQ Battery(ies) in storage, ensure that AC power
is not present and that the DC switch is in the Locked position. While in
storage, damage to the battery can occur from over-discharge. If the battery
state of charge falls to 0%, the IQ Battery(ies) can be damaged or destroyed.
Because of this, the IQ Battery(ies) must only be stored for a limited amount
of time.
• The IQ Battery(ies) must be installed and energized by the “Must
Energize By” date on the shipping box label.
• The IQ Battery(ies) must have a charge state of no more than 30%
when placed in storage. To do this, the IQ Battery(ies) must be placed
in Sleep Mode.
• If the IQ Battery(ies) is already been installed, it must be placed
into Sleep Mode prior to uninstalling. A battery in Sleep Mode can be
stored a maximum of two months after being placed into Sleep Mode.
✓

SAFETY
IMPORTANT SAFETY INSTRUCTIONS. SAVE THESE INSTRUCTIONS. This guide contains important instructions that you must follow during installation
and maintenance of the Enphase IQ Battery(ies). Failing to follow any of these instructions may void the warranty (enphase.com/warranty).
In Case of Fire or Other Emergency
In all cases:
•
If safe to do so, switch off the AC breaker for the IQ Battery circuit, and if an
isolator switch is present, switch off the AC isolator for the IQ Battery circuit.
•
Contact the re department or other required emergency response team.
•
Evacuate the area.
In case of re:
•
When safe, use a re extinguisher. Suitable types are A, B, and C dry chemical
re extinguishers. Additional extinguishing media include carbon dioxide, or
alcohol-resistant foams.
In case of ooding:
•
Stay out of the water if any part of the IQ Battery(ies) or wiring is submerged.
•
If possible, protect the system by nding and stopping the source of the
water, and pumping it away.
•
If water has contacted the battery, call your installer to arrange a inspection.
If you are sure that water has never contacted the battery, let the area dry
completely before use.
In case of unusual noise, smell or smoke:
•
Ensure nothing is in contact with the IQ Battery(ies) or in the venting area of
the IQ Battery(ies).
