Modes of Operation
Once the batteries have been connected, the unit
becomes operational and performs a quick self-test.
When AC power is present at the inputs, the unit
performs as a charger regardless of the position of the
slide switch on the control panel.
When no AC input power is present, the slide switch
provides a manual method of selecting operational
modes for the unit (e.g., INVERT, CHG, and SEARCH
modes).
INVERT Mode
When the unit is in INVERT mode and it detects no AC
power available at its input plug, it will take DC power
from the battery and inverts it to AC power. That AC
power is then routed to the AC output receptacles to
power the AC loads connected to it. The duration of time
the unit can invert power is directly related to the size of
the battery (or battery bank).
To run the unit in “INVERT” mode, move the slide switch
to INVERT on the control panel.
CHG Mode
When no AC power is present, this is the OFF position for
the unit and will not provide backup power to the
connected loads. When the unit is in CHG mode and it
detects AC power available at it’s input plug, it will route
power to the battery charger and charge the batteries
back up to the specified level.
To run the unit in “CHG” mode, move the slide switch to
CHG on the control panel.
SEARCH Mode
To conserve battery power when an input source of AC
voltage is not available (as during a grid failure), the
SRCH
mode can be selected. In this mode, the unit
checks the AC output circuit to see if a load has been
turned ON. If it detects a load, the unit switches to full
output power to operate the load. When the load is
switched OFF, the unit resumes its sleep mode and
continues to monitor the output circuit.
To run the unit in SEARCH Mode, move the slide switch
on the control panel to the SEARCH position.
The unit is now set to switch OFF the AC output during a
grid failure until the minimum load requirements are
met.
NOTE: Selecting search
mode may result
in a slower
transfer for power
in the event of a
power outage.
