Power Source Requirements

Your inverter will operate from input voltages between 11 and 15 volts
DC. If the input voltage drops below 10 volts DC, the inverter will
shut down. This feature protects the battery from being completely
discharged.
The inverter will also shut down if the input voltage exceeds 15.6 volts.
This protects the inverter against excessive input voltage. Although
the inverter has built-in protection against over voltage, it may still be
damaged if the input voltage exceeds 15 volts.
Your inverter is engineered to have standard electrical and electronic
equipment directly connected to it in the manner described in the
"Installation" section of this Instruction Manual. Do not connect the
inverter to household or RV AC distribution wiring. Do not connect
the inverter to any AC load circuit in which the neutral conductor is
connected to ground (earth) or to the negative of the DC (battery)
power source.
Inductive loads, such as TVs and stereos, require more current to
operate than resistive loads of the same wattage rating. Induction
motors, as well as some TVs, may require two to six times their rated
wattage to start up. Because these inverters have a peak watt power
rating, many such appliances and tools may be safely operated. The
equipment that needs the highest starting wattage are pumps and
compressors that start under load. This equipment can be safely tested.
If an overload is detected, the inverter will simply shut down until the
overload situation is corrected. Use the power button to turn off the
inverter, then on again to reset it.
CAUTIONS
• Exceeding recommended voltage limits will void manufacturer's
warranty.
• NEVER try to use your inverter with any 12 volt DC power source
that uses a positive ground. (Most vehicles and boats use negative
ground systems.)

• The Power Inverter must be connected only to batteries with a
nominal output voltage of 12 volts. The unit will not operate from a
6 volt battery and will sustain permanent damage if connected to a
24 volt battery.
• Reverse polarity connection will result in a blown fuse and may cause
permanent damage to the inverter.
Protective Features
The inverter monitors the following conditions:
Input Voltage Too Low: This condition is not harmful to the inverter,
but could damage the power source, so the inverter will automatically
shut down when input voltage drops below 10.5 ± 0.5 volts DC.
Input Voltage Too High: The inverter will automatically shut down
when DC input voltage exceeds 16 ± 0.5 volts, as this can harm the
unit.
Thermal Shutdown Protection: The inverter will automatically shut
down when the unit becomes overheated.
Overload/Short Circuit Protection: The inverter will automatically
shut down when an overload or short circuit occurs.
Refer to "Power and Fault Indicators on the LCD Display" for an
explanation of the icons that indicate a fault condition before shutdown.
To restart the unit, simply unplug all devices plugged into the inverter;
disconnect the inverter from any 12 volt DC power source; then
reconnect the inverter BEFORE plugging the appliance(s) back in.

Power and Fault Indicators on
the LCD Display
Indicates that the unit is connected
properly and is ready to use. The AC
outlet icon and USB icon will light solid
and the Digital Readout shows "0W".
The bars on the Battery Icon represent
the voltage level of the connected power
source.
Indicates that the unit is functioning
normally. The AC outlet icon and USB
icon will light solid and the Digital
Readout shows the total output wattage
of AC outlets. The bars on the Battery
Icon represent the voltage level of the
connected power source.
This indicates an input voltage too low
fault condition. The fault icon and the
empty battery icon will light solid and
the unit will emit three beeps every five
seconds. Refer to the following section
for an explanation.
This indicates an input voltage too high
fault condition. The fault icon and the full
battery icon will light solid and the unit
will emit three beeps every five seconds.
Refer to the following section for an
explanation.
This indicates a thermal fault condition.
The fault icon and the overheat icon will
light solid and the bars on the Battery
Icon represent the voltage level of the
connected power source. The unit will
emit three beeps every five seconds.
Refer to the following section for an
explanation.
This indicates a USB fault condition, and
displays when the USB load exceeds
capacity. The USB icon will flash and the
Digital Readout shows the total output
wattage of AC outlets. The fault icon and
the AC outlet icon will light solid and the
bars on the Battery Icon represent the
voltage level of the connected power
source. The unit will emit three beeps
every five seconds.
This indicates an overload or short circuit
fault condition. The AC outlet icon will
flash and the Digital Readout shows
0W. The fault icon and the USB icon will
light solid and the bars on the Battery
Icon represent the voltage level of the
connected power source. The unit will
emit three beeps every five seconds.
Refer to the following section for an
explanation.
