4.4. Controls, Indicators and Alarms:
Refer to FIGURE 1 if necessary. The inverter is equipped with an ON/OFF switch
located on the front panel of the inverter.
4.4.1. A green Light Emitting Diode (LED) illuminates when the inverter is
correctly connected to an operating 12 VDC power source.
4.4.2. Two rectangular red LEDs indicate the inverter status:
One red LED illuminates to indicate an over-temperature condition. If this LED
illuminates, switch the inverter OFF. The inverter may be overheating because of
insufficient air circulation or it may be operating above its 3000 watt rating.
Correct the condition and allow the inverter to cool off for at least 15 minutes
before switching it back ON. If the inverter has shut itself down due to an over-tem-
perature condition, it will automatically reset and can be restarted once the unit has
sufficiently cooled.
The other red LED illuminates to indicate that the inverter has shut itself off because
of severe overload. Switch the inverter OFF and correct the situation. Then switch
the inverter back ON. Do NOT restart the inverter unless the overload condition
has been identified and corrected.
4.4.3. Two LED bar-graph vertical indicators show the 12 VDC power
supply condition:
One vertical indicator shows the 12 VDC power input supply voltage level in
1 volt increments from 10 volts DC to 15 volts DC. This indicator is color-coded.
Ideally, the voltage should remain in the green area of this display. If the voltage
goes into the red areas at the top or the bottom of this display, the inverter may
shut down. At high input current drain, the indicated DC voltage will be less than
the measured power source voltage due to the voltage drop across the cable and
the connections.
The other vertical indicator shows the amperage being drawn by the inverter in
50 amp increments from 50 amps to 300 amps. This indicator is also color-coded
and the current draw should remain in the green area for long-term operation. The
inverter will operate for short periods of time with the current draw in the yellow
area, but if the current draw rises into the red area, the inverter will automatically
reduce its output voltage to avoid damage and it may shut down.
NOTE: The Amperage Drawn indicator described above ONLY shows the current

NOTE: THE AC RECEPTACLES ON THE FRONT OF THE
EQUIPPED WITH 15 AMP CIRCUIT BREAKERS. THESE RECEPTACLES
THEREFORE ARE CAPABLE OF MAXIMUM OUTPUT OF 1650 WATTS
EACH (110 VOLTS AC X 15 AMPS). TO USE THE MAXIMUM OUTPUT OF
MAXXSST
3000 WATTS, THE
DC POWER SUPPLY CAPABLE OF PROVIDING 300 AMPS AND THE
LOAD SHOULD BE DISTRIBUTED AMONG TWO RECEPTACLES AND/OR
THE HIGH OUTPUT HARD-WIRE AC TERMINAL BLOCK SUCH THAT THE
TOTAL INVERTER OUTPUT IS NOT MORE THAN 3000 WATTS. IF ANY
BREAKERS ARE TRIPPED, REDISTRIBUTE THE LOAD AND RESET THE
CIRCUIT BREAKERS.
A. Power Output - The inverter will operate most AC loads within its power rating
(3000 watts continuous.) When determining whether a microwave oven can be
operated by this inverter, remember that the power rating commonly advertised for
microwave ovens is that of the oven's cooking power (the power delivered to the
food) not the power actually consumed by the oven. But, some models consume
up to 40% more than the advertised cooking power. Be sure to check the rating
sticker on the back of the oven to determine the actual power draw.
Some induction motors used in refrigerators, freezers, pumps, and other motor-operated
equipment require very high surge currents to start them. The inverter may not be
able to start some of these motors even though their rated current draw is within
specifications for this power inverter.
If a motor refuses to start, observe the battery voltage indicator while trying to start
the motor. If the battery voltage indicator drops below 11 volts while the inverter is
attempting to start the motor, this may be why the motor won't start. Make sure that
the battery connections are tight and that the battery (or batteries) is (are)
fully-charged. If the connections are good and the battery is charged, but the
voltage still drops below 11 volts, you may need to use a larger battery (or battery
combination).
B. Input Voltage - The inverter will operate from input voltages ranging between
10.5 and 15 VDC. If the voltage drops below 10.6 volts, an audible low battery
warning alarm will sound and the voltage indicator will be in the lower red zone.
The inverter will shut down if the input voltage drops below 10.6 VDC. This built-in
feature protects the source battery from being completely discharged.
The inverter will also shut down if the input voltage exceeds 15.0 volts. This protects the
inverter against excessive input voltage. The voltage indicator will be in the upper red
zone. Although the inverter has built-in protection against overvoltage, it may still
be damaged if the input voltage exceeds 15.2 volts.
NOTE: Exceeding the recommended voltage limits will void the
manufacturer's warranty.
