Operating Indicators
:
Red and green LED Indicators on top of your inverter will show the status of
the inverter and alert you to conditions that could cause the inverter to shut
down.
Current Overload Protection
:
If the inverter is overloaded, it will shut down to protect itself. The red LED
will illuminate to indicate Overload Protect. To restore normal operation,
disconnect the excessive load and turn the unit Off and On again using the
Power Button.
CAUTION:
Although the inverter has protection against over-voltage, it may
still be damaged if the input voltage were to exceed 16 volts.
Low Voltage Protection
:
If the DC input voltage drops below 11 volts, the red LED will light up to
indicate Low Voltage Protection, but the unit will continue to operate. If the
input voltage drops to 10.5V or less, the inverter will shut down to protect the
battery, the red LED will be lit and the alarm will continue. To restore normal
operation, return the DC input voltage to at least 12V. The inverter will
automatically return to normal operation.
High Voltage Protection
:
If the DC input voltage rises above 15 volts, the inverter will shut down to
protect itself, the red LED will light up to indicate a high voltage protection. To
restore normal operation, return the DC input voltage to less than 15 volts.
The inverter will automatically return to normal operation.
Over Temperature Protection
:
If the internal inverter temperature rises above the alarm threshold, the unit
will continue to operate. If the internal temperature rises to 104ºF, the inverter
will shut down to protect itself.
NOTE: Internal inverter temperature can rise due to being operated in a high
heat environment or due to the fan or vents being blocked during operation
(even in relatively cool outside air). To restore normal operation, turn the unit
off and allow it to cool. The inverter will automatically return to normal
operation after it has cooled.
USB Outlet
: The USB outlet will supply 5 volts at 500ma to charge and power
cell phones, iPods ® and other small electronics.
