Best for average homes ( 3-4) rooms
850W is enough to hold power for 4-5 hours with 160AH battery. It is too good if battery ?? is also of Luminous. It helps for warranty process if both are of luminous.
It has been working in my house for 2 years without any damage or fault.
According to me its 850W inverter but it will be good to consume 400-500 watt power. It will increase your life of battery also.
After all according to me combination of luminous inverter and battery is too good and I satisfied with it. I hope it it keep works in future.
Thanks
