Today I think powercuts are very often in villages and small towns but inverter gives us support in case of powercuts.
Luminous inverters are very good in powerbacks and gives un interpetted power back ups.
They are the best at low cost which having online service warranty 1 year and offline service warranty for 2 years.Battery fully charged gives power backup of nearly 6-7 hours on full load.
I havebeen using this inverter for more than 5years till the day I have not got any service related problem.so my suggestion is to buy only luminous inverter to make your life easy.
