HOMEOWNER’S GUIDE
Enphase Storage System
The Enphase AC Battery
The Enphase Storage System includes the Enphase AC Battery™ and uses the Enphase Envoy-S
Metered™ to measure PV production, home energy consumption, and energy storage. The system
knows when it is optimal to charge or discharge battery power so that energy is stored when it is
abundant and used when scarce.
Access Your System Online
You can view your PV solar production, your electricity consumption, and your energy storage using
Enphase MyEnlighten™. Once your installer creates a prole with your email address, Enphase will
email your system’s unique MyEnlighten web link and a temporary password. Read the Enlighten

aLED Overview
The LED glows red while the AC Battery boots up. If the LED remains red for more than two minutes, the
battery is charging and will do so until it reaches a minimum state of charge (up to 30 minutes). After the AC
Battery boot sequence is complete, the LED becomes blue or green (depending on the charge level). If the
LED remains red after one hour or changes to a ashing red state, contact your installer.
None of the following LED states presents a safety issue.
If the LED is... The AC Battery is...
Slowly ashing green Charging
Slowly ashing blue Discharging
Solid blue or green Idle; color transitions from blue to
green as state-of-charge increases*
Solid red Starting up
Flashing red In an error state; contact your
installer
Solid amber Not operating due to high
temperature; see “Troubleshooting”

*Check MyEnlighten for charge status.
WHERE TO PLACE THE BATTERY
A professional solar installer will mount the AC Battery on the wall and hardwire the unit into your electrical system. You
and your solar installer should keep the following things in mind when choosing a location to install your AC Battery(ies).
• Choose an easily accesible, well-ventilated, and unoccupied indoor location, such as a garage. This location must be
out of direct sunlight, and ambient temperature must stay between -20° C to 45° C (-4° F to 113° F).
• The AC Battery is not waterproof, so do not allow liquids to come into contact with the AC Battery. Choose a dry
location unlikely to be affected by rain, humidity, or ooding. Make sure that the area stays within the 5% to 95%
relative humidity, non-condensing range.
• Ensure that the wall can sustain the weight of the AC Battery and mounting bracket (28kg or 60 lbs per battery).
• Do not place the AC Battery in a location that will block the vents. The AC Battery must be installed at least 300mm
(one foot) above the ground and at least 300mm (one foot) below the ceiling.
• Place the AC Battery away from moving objects such as cabinet doors, garage doors, or motor vehicles.
• Ensure that there are no pipes or electrical wires where your installer plans to drill.
LED OPERATION
The AC Battery unit contains no user serviceable parts, so always contact your solar professional for assistance in
troubleshooting and maintaining your Enphase system. Information about the LED is provided as a reference.
bTroubleshooting
If the AC Battery LED indicates an error state, you can safely perform the following steps. For any other
issues, contact your solar professional. Do not attempt to open or repair the AC battery.
A) If the AC Battery LED is solid amber, check the temperature in the room and increase cooling
and/or ventilation as required by the ambient temperature specication.
B) During a brownout or blackout, the AC Battery powers down automatically and the LED will turn
completely off. This is normal. When power is restored, it automatically starts up again.
C) If you do not see current AC Battery information in MyEnlighten, check that your Envoy-S and your Internet
connection are working. Information from your system may take up to 24 hours to appear in MyEnlighten.

INTERNET CONNECTIVITY
The Enphase AC Battery is intended to operate with an internet connection. Maintaining an internet connection is
important, not only for updating software/rmware, but also for measuring the health of the battery. Failure to maintain
an internet connection may have an impact on the warranty. See enphase.com/warranty for full terms and services.
SAFETY CONSIDERATIONS
There are a few safety considerations to keep in mind once the battery is installed. The AC Battery is not designed
to support additional weight, so never rest anything on top of the AC Battery. Even light objects such as drinks could
condense and drip liquids onto the battery. Other objects could block the vents and cause overheating. Do not store
ammable, sparking, or explosive objects near the AC Battery, and make sure there is a working smoke detector in the
room. Keep moving objects that could fall onto or collide with the unit away from the AC Battery.
