The Enphase Ac Battery - enphase AC Battery Installation Manual

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.
