Page 4: Safety
In all cases: If safe to do so, switch off the AC breaker for the AC Battery circuit, and if a disconnect switch is present, switch off the AC disconnect for the AC Battery circuit. Contact the fire department or other required emergency response team. - Page 5 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.
- Page 6 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.

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). - Page 9 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. -
Page 11: Install The Wall-Mount Bracket
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. -
Page 12: Install The Ac Disconnect (If Required)
WARNING! Risk of equipment failure. Size the conductor gauge to account for voltage rise for both the branch circuit and all upstream conductors leading back to the PCC (point of common coupling). Refer to the technical brief on voltage rise at enphase.com/support. © 2016 Enphase Energy Inc. -

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. -
