System Operating Parameters
When operating your system, keep in mind the following operating parameters to ensure
sufficient battery and output power capacity to adequately power your loads,
Table 2
.
Operating Parameter
Description
BMS Low Battery Cutoff
Vulcan’s battery management system (BMS) protects the internal
Lithium Iron Phosphate (LiFePO4/LFP) battery from being overly
discharged. The BMS will cut off the battery output when the
battery discharges to
10.8V
in order to protect the cells. This will
power off the display and the on/off power button illumination.
In order to reactivate the battery, the Vulcan must be charged
from grid/shore power, an Energy Store (
page 30
) or solar panels
(
page 23
).
Inverter Low Battery
Cutoff
In order to preserve battery capacity, the AC output power will
shut off when the battery voltage discharges down to
11.2Vdc
.
Low AC Voltage Threshold
Vulcan will switch to battery power when the grid/shore voltage
drops below
90Vac
.
AC Output Voltage
This is the voltage of the grid/shore power when active or the AC
output voltage of the Vulcan when running on battery power.
Battery float voltage
This is the resting voltage shown on the Vulcan display. The value
is
13.6Vdc
and will rest there while Vulcan is running from
grid/shore power.
Automatic Transfer Switch
Speed
This is the speed at which Vulcan switches from grid/shore to
battery and from battery to grid/shore power. The standard
Vulcan switching speeds are
10ms
and
20ms
. This may cause a
noticeable flicker in lights but will not affect the operation of TV,
computing, medical, and networking equipment.
Inverter Fault Recovery
Automatically retry three (3) times. After which, the load that
caused the fault must be removed and the power on/off button
Figure 1. [1]
must be manually depressed to off then to on to
restore the AC output power.
Power Save Time
The AC output will shutdown after 25 hours of no-load/idle. The
power on/off button must be cycled to restart.
