Chapter 1: Overview
The Backup Interface is a key component in SolarEdge's Flexible Backup solution,
controlling disconnection of house loads from the grid in the event of grid interruption.
Homeowners are automatically provided with backup power in the event of grid
interruption to whole home or 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
StorEdge 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.
Backup Interface
(optional)
- controls disconnection of house loads from the grid
and integrates the following components to enable grid-tied solar backup and
Smart Energy Management:
Energy 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.
Auto-transformer
- handles the phase load balancing.
200A microgrid interconnection device - disconnects the house loads from
the grid in case of a power outage.
Generator hardware support
- supports connection for up to 15kW alternative
power supply. Generator connection requires supporting inverter firmware.
One or two batteries
- DC-coupled batteries designed to work with the SolarEdge
system.
