By Belal Khan

The inverter and UPS system market in India has witnessed consistent growth in recent years on account of the demand and supply gap in electric power supply, the expansion of industries and rising income levels of consumers. Manufacturers are aiming to tap the demand for environment-friendly, zero maintenance inverters and UPS systems, which are the latest trend in the market.

What to check prior to purchasing a UPS system and inverter

  • Built-in UPS system
  • Square wave, modified sine wave or pure sine wave
  • Size of the inverter
  • Backup duration/battery size
  • Type of battery (standard, tubular or SMF)
  • Preferable to have the same battery and inverter brands
  • Protection features
  • Innovative features like auto adjustment to
    battery, multiple charging, etc.
