Microtek Super Power 900 (Pure Sine Wave) vs V-Guard Nextgen 850

Two 12 V home inverters of about the same size, side by side on the specs each maker states. They differ on rating, output wave, warranty.

  • Specs from makers’ pages
  • Backup worked out the same way for both

Side by side

“Not stated” means the maker’s page doesn’t give it, not that the inverter lacks it.

What each adds to your bill

At half its comfortable load. Standby is 1% of rated watts, an assumption: no Indian brand publishes it.

Backup

Backup depends on the battery, not the inverter brand: with the same batteries and load, both give about the same hours.
