Fronius Primo GEN24 3.0 Plus, Operating Instructions Manual, Page: 95 / 160

IMPORTANT!
When configuring "PV Point" backup power mode, the information in chapter Safety on
page 70 must be observed.
When configuring "Full Backup" backup power mode, the information in chapter Safety
on page 75 must be observed.
Backup power nominal voltage
When backup power mode is activated, the nominal voltage of the public grid must be
selected.
State of charge warning limit
A warning is output when the residual capacity of the battery specified here is reached in
backup power mode.
Reserve capacity
The set value results in a residual capacity (depending on the capacity of the battery)
that is reserved for backup power. The battery is not discharged below the residual capa-
city in grid-connected operation.
Load management
Up to four pins can be selected for load management here. Additional load management
settings are available in the "Load management" menu item.
Default: Pin 1
Australia - Demand Response Mode (DRM)
The pins for control via DRM can be set here:

IMPORTANT!
If the Demand Response Mode (DRM) function is enabled and no DRM control is con-
nected, the inverter switches to Standby mode.
