DANGER: Risk
of fire.
During use, or while transporting, keep the AC Battery in an area that is well ventilated and protected
from the elements, where ambient temperature is between -20° C and 30° C, away from moisture and
sources of heat, and/or flames. Do not install the AC Battery at elevations of over 2,000 m above sea
level.
If the AC Battery generates smoke, remove AC power from the Enphase System so that
charging/discharging stops.
Do not allow or place flammable, sparking, or explosive items near the AC Battery.
DANGER: Risk
of electric
shock.
Do not use Enphase equipment in a manner not specified by the manufacturer. Doing so may cause
death or injury to persons, or damage to equipment.
Be aware that installing this equipment includes risk of electric shock. Do not install the AC Battery
without first removing AC power from the photovoltaic system. Disconnect the power coming from
the photovoltaics before installing.
In areas where flooding is possible, install the AC Battery at a height that prevents water ingress.
Always de-energise the AC branch circuit during an emergency. Never disconnect the DC connectors
under load.
A battery can also present 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 rubber gloves and boots.
• Do not lay tools or metal parts on top of batteries.
Do not work alone. Someone should be within hearing distance or close enough to come to your aid
when you work with or near electrical equipment.
WARNINGS:
Risk of property
or equipment
damage
Do not use the CAN port on the AC Battery. It is intended to be used by Enphase technicians only.
Install the AC Battery only on a structurally suitable wall using an Enphase wall-mount bracket.
Before installing or using the AC Battery, read all instructions and cautionary markings in the
technical description and on the equipment.
Do not install or use the AC Battery if it has been damaged in any way.
Do not exceed the maximum number (13) of AC batteries in a 20A AC branch circuit.
Do not sit on, step on, place objects on, or insert objects into the AC Battery.
The AC Battery is not waterproof. Do not place beverages or liquid containers on top of the AC
Battery. Do not expose the AC Battery to liquids or flooding.
Damage to the battery can occur from over-discharge. While in storage, the AC Battery will discharge.
If the battery state of charge falls to 0%, the AC Battery can be damaged or destroyed. Because of
this, the AC Battery must only be stored for a limited amount of time.
• The battery must be installed and energised by the “Must Energize By” date on the shipping box
label.
• The battery must have a charge of no more than 30% when placed in storage. To do this, place
the AC Battery in Sleep Mode.
• If the AC Battery has already been installed, place the battery in Sleep Mode before uninstalling.
An AC Battery in Sleep Mode can be stored for a maximum of two months from the date it was
placed in Sleep Mode.
• When storing the AC Battery, ensure that there is no AC power flow to the battery, and that the
DC connector is unplugged.
