Removing the AC Battery

In the event that one or more AC Batteries needs to be temporarily uninstalled, or if Enphase Customer
Support authorizes an AC Battery replacement (RMA), perform the following steps.
1. Prior to uninstalling an AC Battery, you must initiate battery Sleep Mode to ensure that the state
of charge is not too high or too low for storage or transport. Once Sleep Mode is initiated, the AC
battery will continue to operate until it reaches the desired state of charge. Since the rate at
which the AC battery can charge or discharge is governed by the loads connected at the point of
coupling, it can take several hours for the desired state of charge to be reached and for the AC
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). Using Enlighten Manager, you can remotely enable one or

more AC Batteries to initiate Sleep Mode by selecting this option under the Devices tab.
 At the site. Using the Installer Toolkit App, you can connect to the Envoy and enable
Sleep Mode for one or more AC Batteries using the Storage button on the App.
Enphase Support. Contact Enphase Support at

assistance activating Sleep Mode for one or more AC Batteries.
Once the desired state of charge is reached for the AC Battery(ies) operating in Sleep Mode, the
AC Battery enters into an idle state and you will be alerted that the battery has 'Fallen Asleep'.
