    FREQUENTLY ASKED QUESTIONS

    1. What Size Inverter Should I Get?

      The size of inverter you choose will ultimately depend on your application. Our inverters are sized in Wattage (Voltage * Amperage) and you can generally figure out what size you will need by looking at the devices you intend to use. Inspect near the power cord or in the user manual for most devices and you should locate a label which lists the continuous wattage or an amperage value (For example, it may say 115v 50/60hz 1.4a 200 watts)

      It is generally a good idea to go with a larger sized inverter to reduce the strain and to account for unexpected energy draws. Heating appliances and motorized appliances tend to have a very large starting surge which lasts for several seconds which is longer than the peak power of an inverter is designed to last. For heating and motorized devices, we recommend choosing a model with at least double the continuous rating. For example, a 700 watt Freezer may draw up to 1400 watts or more during startup.

    2. What’s the difference between Pure Sine Wave and Modified Sine Wave inverters?

      Modified Sine Wave (MSW) inverters are the most common style of inverter on the market. They use less expensive components internally to generate a simulated AC current. Our “wave” is tuned so that it works with as many devices as possible, but there are some devices which we do not recommend using an MSW with with.

      • Laser Printers
      • Sensitive Electronics (Testing equipment, meters, precision tools)
      • Medical Equipment (Oxygen concentrators, CPAP machines, etc…)

      If there is any doubt, you can contact the manufacturer of the device in question and ask if it will work on a Modified Sine Wave inverter.

      Pure Sine Wave inverters produce a higher quality output which is similar or better than the power you receive from your household wall outlet. These models are more expensive and less common as most applications will work fine on Modified Sine Wave inverters.

    3. Can I plug my inverter into the DC port (Cigar Lighter port) in my car?

      A vehicle DC port is usually rated to 10-15 amps @ 12v. This means that the port is limited to about 120-180 watts. We provide a Cigarette Lighter Plug (DC port Adapter) with our units that output 500 watts or less. In order to use more than 120-180 watts, you would need to connect the inverter directly to a battery. For larger sized inverters, you would need to install the unit using battery cables with ring connectors.

    4. I just tested my inverter and saw 90 volts. Why is my inverter only showing 80-100 volts on my multimeter?

      Our Modified Sinewave inverters produce nonsinusoidal ac waveforms which average-responding multimeters have trouble reading. You must use a “True-RMS” (which uses the Root Mean Square method) meter to get an accurate readout of the output voltage of a Modified Sinewave inverter. More reading here.
