Planning

The Enphase AC Battery is controlled by the Enphase Envoy-S Metered gateway. The AC Battery cannot
function if it is not receiving commands from the 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).
However, this may not always be practical since the Envoy-S Metered also needs to be connected to the
production and consumption CTs that are installed around the main service and solar production circuits. In
this case, you may need to extend the CTs and reroute the solar circuit to a location closer to the AC
Battery(ies). One solution is to install the AC Battery, the solar production circuits, and the Envoy-S off a
common subpanel.

Preparation

a. Ensure that you have both of the following:
One or more Enphase AC Battery(ies) (Model B280-1200-LL-I-US00-RF0): the AC Battery shipping

box contains an Enphase AC Battery and an access panel cover.
NOTE: Check the "Must Energize By" label on the shipping box to verify that the AC Battery
will be installed by the date shown.
