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.

CAUTION: TO REDUCE THE RISK OF PROPERTY DAMAGE:

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.
