Information
The following information is available about Peak Load Reduction.
Parameter
Description
Where to find:
State
Indicates if PLR is inactive, active, unable to start, or
held at minimum bus voltage

Web: Control Processes >
Peak Load Reduction
Time Running
The time that PLR has been running.
Scheduled Start
Time
The start time for PLR.
Time shown on SC300 is UTC. Time on PC running
DCTools/Web is local time. See SC300 Internal
Clock on page 19.
Scheduled Start Time and Duration may be
manually set, or set by a remote application such as
EDREM
.
Scheduled
Duration
The time that PLR will remain active.
Offset Voltage
The adjustment to the bus voltage being applied due to
PLR. While PLR is running, the rectifiers are turned
down to force the battery to carry the load.
Configuration
Set the following parameters.
Parameter

Activating Smart
Alarm
The number of the Smart Alarm that triggers PLR.
“0” means no Smart Alarm trigger.
The web view will also show the name of the
Activating Smart Alarm.
Solar Charger Power Share
Where a DC power system has energy inputs both from AC mains supply (or AC generator) and
solar or wind, then the SC300 must share the load power between these sources.
Generally, the preference is for the load to be supplied from the alternative energy source first, and
take energy from AC only when there is not enough solar or wind energy.
This is done by increasing the solar charger rectifier voltage slightly. The AC powered rectifiers
remain set at the normal float voltage.
Solar charger power share automatically operates when an ASC48-ES solar charger is present.
