NOTE: APPLIANCE SPECIFICATIONS MAY VARY FROM BRAND TO
BRAND. THIS TABLE IS OFFERED ONLY AS A GUIDE TO APPROXIMATE
POWER RATINGS. CHECK APPLIANCE MANUALS OR PRODUCT LABELING
FOR ACTUAL RATINGS. TO USE THE MAXIMUM OUTPUT OF
CONTINUOUS WATTS, MAXX SST MUST BE CONNECTED TO A DC
POWER SUPPLY CAPABLE OF PROVIDING 1/10TH OF INVERTER’S
CONTINUOUS WATTAGE RATING.
A. Power Output
The inverter will operate most AC loads within its power rating. Some induction
motors used in refrigerators, freezers, pumps and other motor-operated equip-
ment, 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 with-
in specifications for this power inverter.
If a motor refuses to start, observe the battery voltage using a DC voltmeter while
trying to start the motor. If the battery voltmeter 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 between 10.5 and 15.5VDC. If the
voltage drops below 10.6 volts, an audible low battery warning alarm will sound.
The inverter will shut down if the input voltage drops below 10.5VDC. This built-
in feature protects the battery from being completely discharged.
The inverter will also shut down if the input voltage exceeds 15.5 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 15.5 volts.
NOTE: Exceeding recommended voltage limits will void manufacturer’s warranty.
