Generators compared to Inverter and battery based, Backup Power Systems

Some turn to generators for backup power solutions, but there is a better way, and this is: batteries and inverters.
Generators are OK as a short term quick and dirty solution, but for long term regular power failures an inverter with batteries are much better.

Inverter with batteries

  • Very quiet operation
  • No air pollution
  • Requires no maintenance
  • Use solar power or Eskom power to charge batteries
  • Automatically and immediately supplies power when there is a power failure.
  • Clean safe power for expensive sensitive equipment such as medical devices and electronics.


  • Can be very noisy
  • Cause air pollution and makes smoke.
  • Can be difficult to start
  • Must be kept filled up with fuel
  • Requires regular maintenance
  • Consumes a lot of expensive fuel
  • Can be complicated and dangerous to connect to home DB
