Luminous its big name in inverter industry. last two year I am using luminous inverter its really amazing no problem at all. its easy to use, all indication displayed in his display screen.
when main supply is on he indicate "main on" when main supply is cut off in a micro second he provide battery supply and do beep beep sound five time.
when main supply coming inverter start charging the battery, very silently and indicate charging display. when battery full display automatically turn off.
there is two mode one is "ups" and other is "eco" for only computer you select ups and for home select eco. its setting is very easy one small button behind inverter for select those mode.
if some time overload and inverter trip there is small push button for removed trip behind inverter.
also battery low and battery water(acid) level low indication on display.
I think there is no problem to buy it. its very very good also luminous provided 2 years guarantee, so don’t worry close your eyes and buy it. its safe, less power consuming, reliable, silent, solid metal body, and super easy to use with no maintenance cost so grab it.
(tip: for installation call certificated electrical person. do not attempt if you are not trained person its harmful for you also for inverter)
