Tips: Things to Consider When Buying an Pure Sine Wave UPS Inverter

Pure sine wave ups inverters can seem complex and unbearable, especially if you are not an electrician. However, with some general guidelines, it is easy to understand the most important differences between inverters and why one inverter may better meet your needs than another.

  • Use. First of all, does the inverter need to be portable? For example, for use in a RV or boat? Or, if you use an inverter in combination with a solar array, finding an inverter that can combine solar energy with grid power can save a lot of energy and time. In addition,considering what and how many appliances and devices you plan to power off an inverter will play a large role in determining the wattage and surge power capabilities that you need.
  • Wattage. The wattage provided by your ups inverter is one of its most important specifications, because this number determines how much power you can supply and how many devices you can supply in a single time. Before choosing an inverter, take a look at the power requirements of the device you plan to use most often compared with the inverter, the inverter needs to output at least the power required by each device, and at least the sum of the power required by the device you intend to power at the same time.
  • Continuous power and surge power. Inverter power ratings are usually measured in watts and include the power they output continuously over a period of minutes to hours (called continuous power) and the additional power they output over a period of seconds (called surge power). Continuous power determines how many devices you can power at once. Surge power is a very important consideration if you are using motor driven equipment. Motor-driven equipment usually requires more power to start than to run after starting.
