StorEdge Interface Installation Guide MAN-01-00621-1.1

Chapter 1: Overview
SolarEdge’s StorEdge™ solution for Smart Energy Management uses the StorEdge
Interface to connect the battery to the inverter.
Power is stored in the battery and can be used for various applications such as
maximized self-consumption and time of use profile programming. For backup power,
an inverter specifically designed for backup applications is required; this inverter is not
in the scope of this document.
The StorEdge Solution Components
The Inverter - manages the battery and system energy, in addition to its traditional
functionality as a DC-optimized PV inverter.
The Energy Meter - is used by the inverter for export, import, production and
consumption readings, and for Smart Energy Management applications, such as:
export limitation and maximizing self-consumption.
The StorEdge Interface - The StorEdge Interface connects the battery to the
inverter through fuses, and supplies control and monitoring signals to the battery
for operation.
One battery - a DC-coupled battery designed to work with the SolarEdge system.

Figure 1: StorEdge system components
NOTE
Additional SolarEdge inverters (without batteries) can be connected over
RS485. The inverters will participate in export limitation and Smart Energy
Management.
PV modules connected to power optimizers are not mandatory for charge/
discharge profile programming.

Installation Workflow
When installing the StorEdge system, follow this workflow to ensure all the components
are connected and functioning correctly.
Plan the StorEdge system layout:
The battery and StorEdge Interface will connect to the DC side of the inverter.
Since the inverter DC connections are on its left side, it is recommended to
position the battery and interface to the left of the inverter to simplify wiring.
The total distance between the battery and the inverter, including StorEdge
Interface, should not exceed the maximum distance shown in the figure below:
