Backup Power with Smart Energy Management - System Configurations

Additional Capacity with Two Batteries

For sites where additional battery capacity is needed (for example, to enable backed-up loads to be powered from the battery

for longer periods), two batteries may be connected to a single StorEdge inverter.

In this configuration, only one battery operates at any given time – i.e. the two batteries provide additional capacity only, not

additional power.

The DC connection of the two batteries to the StorEdge Inverter is done in parallel through an external fused combiner box (not

provided by SolarEdge), with a fuse rating of 12A/600V.

The control and thermal connection of the second battery is daisy chained to that of the first battery.

► To configure the system:

For battery RS485 settings:

 Battery 1 is not terminated with ID: 24 and

 Battery 2 is terminated with ID: 25

1 Terminate the battery which is connected last on the RS485 bus (battery 2), and make sure the other battery (battery 1) is

not terminated:

Battery 1 - Unterminated battery:

Battery 2 - Terminated battery:
