An inverter that can give you power during a blackout, without batteries!

Leading inverter manufacturer, Fronius, has recently released its new range of inverters – the GEN24.  Available in single and three phase models, the GEN24 is a significant advancement in inverter technology.  During normal operations it supplies your home or business with electricity and exports excess power to the grid just like its predecessors.  When there is a blackout though, this inverter really shows its difference.  With no battery installed, it can deliver 3kW of power while the sun is shining, providing a low cost solution to back up power.

The GEN24 can also have battery storage added to increase its capability and provide power at night.

Tropical Energy Solutions recently completed what we believe is the first installation of a GEN24 in Townsville.  We were very impressed and believe we will be installing many more in the future.



The integrated basic backup power supply is a power socket supplied with electricity in the event of a power outage. This allows loads to be supplied with up to 3 kW of power. The PV Point represents our low-cost backup power solution.

  • automatic activation in case of a grid outage
  • costly additional installation work is not necessary
  • supplies households with one-phase loads of up to 3 kW


The sophisticated backup power solution* works in combination with an energy storage system and supplies 1- and 3-phase loads, such as an electric cooker or a heat pump, whenever there is sufficient energy available.

  • supplies the entire household (even three-phase loads)
  • automatic switch to backup power in the event of grid failure
  • efficient energy flows due to the Multi Flow Technology, even in backup power situations

*The Full Backup option is possible with Symo GEN24 Plus 6-10 kW and Primo GEN24 Plus 3-6 kW.


Thanks to active cooling, the Fronius GEN24 Plus offers greater flexibility in terms of design and installation right from the planning stage. In addition, lower costs are incurred during operation due to less or no maintenance. Above all, however, it is the longer service life and increased yield due to better performance that speak in favour of the active cooling system:

  • longer service life
  • higher yields
  • lower maintenance costs
  • simple & flexible installation
  • flexibility in the system design


  • Simple installation & service
    Time and cost savings due to quick-release screws, push-in spring terminals and a sophisticated wall mounting system.
  • Commissioning: Fronius Solar.start
    Quick and easy commissioning via your own smartphone or tablet in just three steps.
  • Upgrades possible at any time
    Open interfaces make it easy to integrate third-party components such as home automation systems.
  • Smart monitoring with Solar.web
    Monitor, analyse and compare different PV systems quickly and conveniently on your smartphone, tablet or laptop. Solar.web helps you deliver the best service to your customers.
