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 a low lifetime energy cost for customers with both, new solar installations
and retrofitted installations. 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 is programmed to optimise charging or discharging 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 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 maximises energy production by using a sophisticated
Maximum Power Point Tracking (MPPT) algorithm.
