The next chapters describe each of these configurations for each of the three modes described above, and the required system
setup via the inverter LCD and internal buttons and via the monitoring portal (where applicable).

Backup Power with Smart Energy Management - System Configurations
In this mode, some of the battery energy is reserved for backup power and the rest can be used for Smart Energy Management
applications. In case of a power outage, the inverter automatically switches to backup mode, disconnecting from the grid and
supplying power to backed-up loads.
The configurations described in this section are the following:

Basic Configuration
Basic configuration is based on one of each of the StorEdge
components and is suitable for most residential systems.
8
Large Residential PV Systems
For residential sites with large PV systems, a StorEdge
inverter and a SolarEdge single phase inverter may be
installed together. The StorEdge inverter manages the
battery and functions as a PV inverter, and the second
inverter is used for production of the additional PV power.
During power outages, the StorEdge inverter provides power
to backed-up loads, and the second inverter remains shut
down until the grid is back.
12
Additional Capacity with Two Batteries
For sites where additional battery capacity is needed (for
example, to enable backed-up loads to be powered from the
battery for longer periods), two batteries may be connected
to a single StorEdge inverter.
In this configuration, only one battery operates at any given
time – i.e. the two batteries provide additional capacity only,
not additional power.
13
Additional Capacity and Power
For sites where additional capacity and power are needed
(for example, to enable more backed-up loads to be powered
simultaneously). In this case two StorEdge inverters and two
batteries may be installed
1
. Each battery connects through a
separate StorEdge Inverter, and each inverter manages the
battery and the PV connected to it. Backed-up loads are
connected to each inverter through separate load panels and
auto-transformers. The inverter connected to the meter
operates as the system manager.
15
AC Coupling using a non-SolarEdge Inverter
For sites with an already installed PV system with a non-
SolarEdge inverter, the StorEdge inverter can be AC-coupled
to the existing inverter, i.e. the StorEdge inverter used to
manage the battery is connected to the AC output of the
existing inverter and charges the battery using the PV power
produced by the non-SolarEdge inverter.
16
AC Coupling without a PV System
For backup power with charge/discharge profile
programming a StorEdge system may be installed without a
PV system. In this case, the battery is charged from the AC
grid only.

Additional capacity and power with one inverter will be supported in H2 2016 and will require new battery and inverter hardware.
