Chapter 1: Overview
StorEdge™ is SolarEdge's all-in-one solution that uses a single phase DC optimized
inverter to manage and monitor both solar power generation and energy storage.
Homeowners are automatically provided with backup power in the event of grid
interruption to power pre-selected loads. Solar energy can be stored in a battery for
Smart Energy Management applications such as export control, offering demand
response and peak shaving, and performing time of use shifting for reduced electric
bills.
The StorEdge Solution Components
The StorEdge Inverter - The inverter manages battery and system energy, in
addition to its traditional functionality as a DC-optimized PV inverter.
The StorEdge Connection Unit, located at the bottom of the inverter, allows simple
installation and connectivity to other system components and includes a DC Safety
Switch.
The Energy Meter - The meter is used by the inverter for export, import, production
and consumption readings, and for Smart Energy Management applications, such
as: export limitation, time-of-use profile programming and maximizing self-
consumption.
The meter is required only in systems using Smart Energy Management applications
(it is not required for StorEdge systems used only for backup power).
The Auto-transformer - The auto-transformer handles the phase load balancing. It
is required only in systems providing backup power.
One or two batteries - DC coupled batteries designed to work with the SolarEdge
system.

NOTE
Additional SolarEdge inverters (without batteries) can be connected with
RS485. The inverters will participate in export limitation and Smart Energy
Management.
Connecting multiple inverters with RS485 master-slave connection may
require an RS485 Expansion Kit (available from SolarEdge).
PV modules connected to power optimizers are not mandatory for charge/
discharge profile programming and for backup power.
Additional Reference
This document describes basic system connection and configuration -
PVsystem (power optimizer strings), one inverter, one battery, backed-
up loads panel and one meter.
For additional configuration options refer to the StorEdge Solution
Applications - Connection and Configuration Guide, available at

18 Installation Workflow

Installation Equipment List
Standard tools can be used during the installation of the SolarEdge system. The
following is a recommendation of the equipment needed for installation:
Standard flat-head screwdrivers set
Non-contact voltage detector
Cordless drill (with a torque clutch)or screwdriver and bits suitable for the surface
on which the inverter and optimizers will be installed and for opening the StorEdge
Connection Unit drill guides. Use of an impact driver is not allowed.
Appropriate mounting hardware (for example: stainless bolts, nuts, and washers)
for attaching:
the mounting brackets to the mounting surface
the power optimizer to the racking (not required for smart modules)
Wire cutters
Wire strippers
Voltmeter
For installing the communication options, you may also need the following:
For Ethernet:
CAT5/6 twisted pair Ethernet cable with RJ45 connector.
If using a CAT5/6 cable spool: RJ45 plug and RJ45 crimper
For RS485:
Four- or six-wire shielded twisted pair cable.
Watchmaker precision screwdriver set
Inverter Transport and Storage
Transport the inverter in its original packaging, facing up and without exposing it to
unnecessary shocks. If the original package is no longer available, use a similar box that
can withstand the weight of the inverter (refer to the inverter weight in the specification
datasheet provided with the unit), has a handle system and can be closed fully.
Store the inverter in a dry place where ambient temperatures are -13°F to 140°F /
-25°C to +60°C.
