Purchasing Tips

Find the lowest-powered inverter power source that is most appropriate to your application.

  • Look for a power factor of 99 percent or higher.
  • Look for an energy conversion efficiency (kVA out over kVA in) near 80 percent.
  • Look for idling power consumption of less than 0.1 kW.
  • Buy from a reliable supplier who provides field maintenance and at least a two-year, all-parts warranty.
  • Check manufacturers' Web sites for warranty information.
  • Shop for competitive prices.
