APPLIANCE POWER CONSUMPTION
MAXX SST™ inverters are ideal for powering:
Lights
TVs and TV/DVD (VCR) combinations units
Radio receivers/transceivers and stereo systems
Computers and peripheral equipment
Refrigerator/freezers
Small microwave ovens
Household appliances
Dry and/or wet/dry vacuums
Heavy duty power tools & chargers
Sump pumps, motors and other electric-powered equipment
Most electrical tools, appliances and audio/video equipment have labels that show the unit’s power
consumption in amps, watts, or both. To avoid inverter shutdown and possible damage to the inverter, avoid
exceeding the wattage rating of this unit. To obtain a rough estimate of the current (in amperes) the power
source must deliver where the power consumption of the tool or device is given in watts AC, simply divide the
power consumption of the load by 10.
Example: If a load is rated at 200 watts AC, the power source must be able to deliver: 200 divided by 10 = 20
amperes.
The inverter has built-in overload protection so that if you do exceed the inverter’s output capacity continuously,
the unit will automatically shut down. Once the excessive load is removed, the inverter can be restarted and
resume normal operation.
Note:
To restart the inverter, turn it off, and then on again. The on/off Switch is located on the unit’s Front Panel
(refer to the “Control and Functions” section of this Instruction Manual).
The inverter powers resistive loads the easiest; however, larger resistive loads, such as electric stoves or
heaters, could draw more wattage than the inverter can deliver on a continuous basis.
CAUTIONS
Ensure that total continuous power consumption of all tools and/or appliances connected to the inverter (and in
use) does not exceed the inverter’s continuous watts rating. Also ensure that start-up wattage for inductive
loads does not exceed peak watts for more than a second.
Appliances such as microwave ovens will normally draw more than their rated current and could possibly
overload the inverter when operating simultaneously with other appliances. For example: A 600 watt
microwave oven draws approximately 940 watts.
The following chart shows the approximate amperage and corresponding wattage at 120 volts AC for various
common tools and appliances.
