I have recently bought this for my home.It’s very essencial for domestic purpose.After power cut you can feel the essinciality of this. Exide is brand on which everyone can depend on it.Further I have to say this is the time to buy inverter ro get an extra discount for festive season.With this power back-up facility we can run tube lights, Fans, tv etc.We have to understand that after power cut if we want to more time back up as mentioned by co. Then you have to consume less power i.e no. Of tube lights, fans should be less.
