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.

When replacing an Enphase AC Battery, you must replace it with an AC Battery of the same type, with the same AC current rating. When stored, the AC Battery is not connected to the grid and no automatic charge of the battery is possible.
The Enphase AC Battery The Enphase AC Battery™ is the heart of the Enphase Storage System. The AC Battery is simple to install, safe, very reliable, and provides the lowest lifetime energy cost for both new solar customers and retrofit customers.
Envoy-S. For that reason, it is critical that the Envoy-S and AC Battery(ies) are located as close as possible to each other. The Envoy should be located within 65 feet (20 m) electrical distance from the AC Battery(ies).

Install the PV system and the Envoy-S as directed by the installation manuals. e. To record the location(s) of the AC Battery(ies), peel the removable serial number label from each battery and affix it to the respective location on a paper installation map. You will scan this map later using the Enphase Installer Toolkit™...
Consider the dimensions of the AC Battery, easy access, height, and length of cable when selecting the location. g. Do not block the vents or allow liquids to contact the AC Battery. The AC Battery is not waterproof. h. Select a location where you can interconnect to the site’s load center using an appropriate branch circuit.
Verify that the wall-mount bracket is solidly attached to the wall. WARNING! Risk of injury and equipment damage. Do not mount an AC Battery on a bracket that is not properly mounted. If installing additional batteries, install the adjacent wall-mount brackets in an interleaved fashion, as needed.
Neutral. b. Using the conductors and suitable conduits, connect the AC disconnect (if used) and the first adjacent AC Battery junction box. Use the openings provided by the knockouts to connect the conduit and pass the wires through them. NOTE: Do not modify or rewire the pre-installed wiring or bonding connections in the junction box.
WARNING: Take care when lifting the AC Battery. The AC Battery is heavy and may require two persons to lift. a. Using both hands, take the AC Battery from the packaging and place it right side up on a flat surface. Be sure that the AC connector is not pinched underneath.
Turn on the circuit feeding the AC Battery(ies). c. The AC Battery LED should now be solid red for the duration of the start-up process. If the LED is not solid red, see following section on Troubleshooting. d. Use the Enphase Installer Toolkit to commission the AC Battery(ies). Once connected to the Envoy, refer to the Installer Toolkit help topics for more information.
Discharging: The AC Battery discharges power only to service local loads. It does not discharge power through the utility meter onto the electric grid. The AC Battery discharges for use by the home if all of the following occur: ...
If needed, you can also provision devices either by scanning the AC Battery(ies) bar code(s) or by performing a device scan. If the AC Battery(ies) cannot be detected by the device scan or if the AC Battery(ies) are not communicating, you need to relocate the Envoy-S to be electrically closer to the AC Battery(ies). This is because the Envoy-S communicates with the AC Battery using power line communications.
If the AC Battery is not working correctly, perform the following steps. If the issue persists, contact Enphase Customer Support at enphase.com/en-us/support/contact. If the AC Battery LED is off, turn off the breaker for the branch circuit, wait for at least one minute, ...
The AC Battery requires an ambient temperature between -4° F (-20° C) and 113° F (45° C), and where relative humidity is between 5 and 95 percent. Check that the front, top, and sides of the AC Battery array have at least one foot of unobstructed ...
Battery to ‘Fall Asleep’. Therefore, Enphase recommends that you initiate Sleep Mode 24-48 hours in advance of the physical removal of the AC Battery. This is to ensure that sufficient time has passed to allow the AC battery to ‘Fall Asleep’. You can initiate Sleep Mode in one of three ways: Remotely (Recommended).
AC Battery Installation 2. Once you have confirmed that the AC Battery has ‘Fallen Asleep’, turn off power to AC Battery at the main load center. Verify that all power is removed from the system before attempting to remove the AC battery.
NOTE: When replacing an Enphase AC Battery, you must replace it with an AC Battery of the same type, with the same AC current rating. Follow the steps in “5. Mount the AC Battery on the Wall” starting on page 10. After installing the new AC Battery, do the following: 1.
