• Operate using reliable and sturdy power transformers.
  • Can operate at a peak power level of 300% of nominal power level for several seconds. They also operate at a cooler temperature.
  • Are ideal for inductive loads and run well with high surge loads and higher power spikes.
  • Are reliable and stable with strong shock resistance.
  • Have a lower efficiency than HF inverter and the no-load loss is higher.
  • Have a wide range of technical features and capabilities.
  • Larger and more bulky due to power transformer.
  • More expensive than high frequency inverter.
  • Relatively simple internal structure makes them easy to repair.
  • Generally carry a 5 year warranty (with optional extended warranties available).


  • Operate using electronic switching.
  • Can operate at a peak power level of 200% of nominal power level but only for a small fraction of a second.
  • Are therefore more likely to burn out when driving inductive loads (water pumps, refrigerators etc).
  • Have a much lower safety performance.
  • Have a high conversion efficiency and the no-load loss is low.
  • Have less technical features and capabilities than LF inverters.
  • Smaller footprint than LF inverter, and therefore also weigh less.
  • Less expensive than low frequency inverter.
  • Due to complex circuitry and many components, they are difficult to repair.
  • Generally carry a 2 year warranty.
In our inverter section you will find both low and high frequency inverters. Low-frequency inverters have the advantage over high-frequency inverters in two fields: peak power capacity, and reliability. Low-frequency inverters are designed to deal with higher power spikes for longer periods of time than high-frequency inverters. read more on this at our inverter section

I did quite a bit of due diligence before embarking on a solar system and choosing a company to do it for us. I consulted Electricians & Electrical Engineers and time and again SSS and the products they recommend were highlighted. Ray Nolan gave excellent technical advice to suit our budget & needs. Lee Naidoo and his team did an excellent installation. Great Installation & brilliant service SSS team! Eugene Marais

The guys at Approved Solar provided a very high quality and professional service They were extremely helpful, providing answers when needed and keeping us up to date. The installation far exceeded my expectations and unlike what is the norm these days the service provided was above and beyond. I would have no hesitation recommending any solution recommened by these guys.
