Installation Manual

Introduction
4
In addition to these three modes, the StorEdge inverter can be used without a battery as a PV inverter with no StorEdge
applications.
NOTE
For configuring the inverter when not using any StorEdge applications, refer to Appendix E - StorEdge Inverter without
a Battery.
NOTE
The StorEdge inverter requires CPU version 3.18xx and above. If an upgrade is required contact SolarEdge support
for an upgrade file and instructions.
All modes can be used together with the export limitation application. For details on export limitation, refer to
http://www.solaredge.com/files/pdfs/export_limitation_application_note_NA.pdf.
Smart Energy Management Applications
Two of the main Smart Energy Management applications are described in this document:

Maximize self-consumption – the battery is automatically charged and discharged to meet consumption needs and reduce
the amount of electricity purchased from the grid.

Charge/discharge profile programming – the system operates according to a configurable charge/discharge profile, for
example for time of use arbitrage (charge the battery from PV/grid when tariffs are low and discharge it when tariffs are
high).
System Components
The StorEdge Solution with Backup comprises the following components:

StorEdge Inverter with Backup – the single phase StorEdge inverter manages battery and system energy in addition to its
traditional functionality as a DC-optimized PV inverter. The inverter connects to the battery through fuses and supplies 12V
to the battery for thermal control.
NOTE
The StorEdge inverter requires CPU version 3.18xx and above. If an upgrade is required contact SolarEdge support for
an upgrade file and instructions.
A revenue grade StorEdge Inverter with Backup is available. It includes a built-in revenue grade meter
that measures inverter production.
NOTE
When using a revenue grade StorEdge inverter :
- The built-in meter is pre-configured as Meter 1 and as a Production meter.
- The Prot and ## in the Communication status screen will increase by 1. For example, if there is an internal meter, an
external meter and a battery, the screen should display Prot=03 and ##=03.

Auto-transformer – The auto-transformer is used for phase balancing in case of backup power: it supplies the inverter’s
240V output to the 120V backed-up loads. It is not required if the system is working in Smart Energy Management mode.

SolarEdge Electricity Meter – the meter is used by the inverter for import/export or consumption readings, and manages
the battery charge/discharge accordingly for Smart Energy Management applications; the meter readings are displayed in
the SolarEdge monitoring portal. The meter is optional for Backup Power only mode.

Battery Pack for Daily Cycle Applications – a DC-coupled battery designed to work with the StorEdge solution

Backed-up loads panel – loads that should be supplied with backup power in case of a power outage should be wired
through a separate load panel. In systems with multiple StorEdge inverter, a backed-up loads panel is required for each
inverter.

Optional: RS485 Expansion Kit – the kit is used for systems with more than one SolarEdge inverter or systems with a third
party controller, and provides an additional RS485 port within the inverter for connection.
System Operating Modes and Configurations
There are various StorEdge system configurations, suitable for different PV systems user needs.
Some system configurations have multiple StorEdge inverters. The inverters are connected to each other with RS485 and appear
under a single site in the monitoring portal.
