Why Choose Inverter Generators?

  1. ​It uses the most advanced technology in generators
    Innovation made way to the development of smaller engines that lead to more stable electricity supply in generators. As the appliances modernize, we start seeing that almost all appliances with a motor like refrigerators and air conditioners run with the inverter technology. Generators are evolving to match this technology and supply the right amount of electricity based on what the appliances need – no overloading and fluctuation. This prolongs the life of our appliances.
  2. It is low noise
    As the delivery of electricity is enhanced by inverter technology, it lessens the strain on the engine. This will result in less noise. Manufacturers also shift to lighter yet noise-minimizing enclosures like plastic.
  3. It is ultra-portable
    As technology advances, electronic parts of generators become smaller too. Manufacturers also shift to molded plastic from all-steel frames and enclosures. A lighter generator can take the extra mile for you, literally.
  4. It is fuel efficient
    Just like inverter type appliances which let you save on electricity cost, inverter generators have regulated electricity supply, and adjust to the needs of specific appliance. Fuel efficiency does not only translate into monetary savings, but it also helps you save the environment by using less gasoline or propane.
  5. It is affordable
    Inverter generators, despite being a little pricier than non-inverter small generators are still more practical than getting the heavy duty ones. Not only it is cheaper to purchase, the replacement parts usually cost less as well.
