Operation; Inverter Power Mode - Sensata Dimensions 12LPC15 Owner's Manual

OPERATION

Once the inverter has been fully installed, wired, and DC power has been applied, the inverter is ready to turn on.
The status LED beneath the AC wiring box on the left side of the inverter shows the current state of the inverter.

Inverter Power Mode

Usage: Any 120 VAC, 60 Hz single phase product within the inverter's power rating.
The inverter can be turned on by using the local or remote switch. When the inverter is on, the local status LED
will be a constant green. When the local "On/Off " switch is enabled in assemblies without the "R" suffix, any
switch may turn the inverter on or off. When using the local switch, a momentary switch must be used for remote
operation. With the remote-only inverter, only the remote snap switch will turn on the inverter. The local "On/
Off " switch will be inactive. The function of the switch will depend on the mode of the unit and if the AUX tab is
enabled and being used.
The inverter front status LED will be green while the inverter is on. The AC power produced by the inverter comes
from the energy stored in the battery bank through an electronic inversion process. A transformer, a Metal Oxide
Silicon Field Effect Transistors (MOSFET), a filter capacitor, and a microprocessor are used to generate clean AC
power.
The inverter will operate at DC input voltages ranging from 10.5 VDC to 15 VDC. If the inverter's input voltage
exceeds 15 VDC, the inverter may stop operating. The inverter can tolerate up to 24 VDC for 5 minutes; if this
condition continues for over 5 minutes, the unit will shut down. Input voltages above 24 VDC will result in an
immediate shutdown. The inverter will restart when the input voltage drops below 16 VDC. When the input voltage
drops to the low battery voltage, the inverter will stop operating. When the lead-acid battery bank voltage drops to
10.5 volts, the battery is fully discharged.
The inverter output needs to be de-rated as the ambient temperature surrounding it increases. See Figure 10 for
operation at 12.6 VDC.
