This is my own experience about Su-Kam Pure Sine Wave Inverter, you will get the good quality, better electricity backup and durability with this inverter. all of the equipment of this Inverter is standard quality and its easy to install and get better electricity backup and this is very user friendly inverter.
Power consumption and battery life: there is two major problem occur first is its consume more electricity and its battery life is not very well. Its battery is okay in the early stages but after 1 year it does not make good backups.
overall Su-kam pure sine wave inverter is good inverter but best.
