The AC Battery is not waterproof. Do not place beverages or liquid containers on top of the AC Battery. Do not expose the AC Battery to liquids or flooding.

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.

 The battery must be installed and energized by the “Must Energize By” date on the shipping box

label.

 The battery must have a charge state of at least 30% when placed in storage.  If the AC Battery has already been installed, the battery must be placed into Sleep Mode prior to

uninstalling. An AC Battery in Sleep Mode can be stored a maximum of two months from the date it was placed into Sleep Mode.

 When placing the AC Battery in storage, ensure that the DC connector is unplugged.

NOTES:

Method of active anti-islanding protection: The AC Battery monitors for sudden changes in the impedance of the grid by looking for changes in the second to the eighth harmonic. If significant changes are detected, then the internal microinverter is de-energized thus preventing islanding.

Perform installation and wiring in accordance with all applicable local electrical codes and standards.

Protection against lightning and resulting voltage surge must be in accordance with local standards.

Using unapproved attachments or accessories could result in damage or injury.

Use Class 1 wiring methods for field wiring connections to terminals of a Class 2 circuit. Use only 12 AWG (2.5 mm2) to 20 AWG (4 mm2) wire in the junction box terminal block. Select the wire size based on the protection provided by the circuit breakers / fuses. Install properly rated over current protection as part of the system installation.

To ensure optimal reliability and to meet warranty requirements, the AC Battery must be installed and/or stored according to the instructions in this guide.

The Enphase AC Battery is compatible only with the Enphase Envoy-S Metered communications gateway with properly installed production and consumption CTs. The Envoy-S is required for operation of the AC Battery. Earlier versions of the Enphase Envoy communications gateway, and the Envoy-S Standard gateway are incompatible.

The Enphase AC Battery is intended to operate with an internet connection. Failure to maintain an internet connection may have an impact on the warranty. See http://enphase.com/warranty for full terms and services.

AC Battery Installation

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. You can install as many batteries as needed to meet the needs of the system owner.

The Enphase Storage System includes the Enphase AC Battery with integrated Enphase Microinverter™. The system uses the Enphase Envoy-S Metered™ to measure PV production and home energy consumption. The system knows when it is optimal to charge or discharge the battery so that energy is stored when it is abundant and used when scarce.

The Enphase Envoy-S Metered operates as a gateway between the storage system and Enphase Enlighten™ web-based monitoring and analysis software. The Envoy-S monitors and controls the AC Battery through the integrated Enphase Microinverter. It collects energy and performance data from all Enphase Microinverters at the site over on-site AC power lines, and it forwards that data to Enlighten, via the Internet, for statistical reporting and system control. The Enphase Envoy-S Metered communications gateway with properly installed production and consumption CTs is required for operation of the AC Battery.

When used with non-Enphase PV systems, the Envoy-S can collect production and consumption data, but it does not control grid management functions of non-Enphase PV system components.

The Enphase Enlighten™ web-based monitoring and analysis software analyses the data collected by the AC integrated microinverter in the AC Battery. Enlighten constantly monitors every Enphase Microinverter connected to the Envoy-S and is essential for system monitoring and troubleshooting. Enlighten provides a wide range of information on system performance. You can access Enlighten on your computer or mobile device at any time.

The Enphase Microinverter converts the DC output of the PV module into grid-compliant AC power. In addition to performing the DC to AC conversion, it maximizes energy production by using a sophisticated Maximum Power Point Tracking (MPPT) algorithm.

AC Battery Installation

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.
