LUVMINOUS INVERTER are the most popular inverter brand. I am using luminous inverter for last five years and till now I don’t had any complaint at all.
The customer services , warranty , battery backup and charging speed all are fantastic.
After full charge it can give us the backup of 6-7 hours .
As it gives longer power backup so this isn’t save electricity one should always have this doubt let me clear it out it is efficient .
It is awesome
