Smart Energy Management Only - System Configurations
In this mode stored energy is used for Smart Energy Management applications only:
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).
A Smart Energy Management only system can be upgraded to support backup power by installing an auto-transformer and
connecting backed-up loads through a separate panel, and reconfiguring the system as described in Backup Power with Smart
Energy Management - System Configurations on page 5.
Configuration is done as described in the Backup Power with Smart Energy Management - System Configurations chapter,
without setting up backup power. System diagrams are shown below.
System Connection
The following diagram illustrates the connection of the system components when using the basic configuration for Smart Energy
Management only: one StorEdge inverter, one meter and one battery. For enlarged segments of this diagram refer to Appendix
D – Detailed System Connection on page 53.

Notes
Note 1: Recommended Fuses in StorEdge Inverter:
12A 600VDC Quick-Acting, 10 x 38 mm Solar Midget Fuses
(Example: littelfuse P/N 0SPF012)
Note 2: Battery connection:
35ft max
Distance larger than 5ft requires installation of external DC
safety switch on the battery side
Control [B-,A+] must be twisted pair
