Does this reset with power cut? Or it has a rechargeable battery?

It has a rechargeable battery and we need not reset it after power cut

I need to use this switch use as my main swicth. I need to off/cut my grid power at night and on at morning. Is that will work?

It will in case your load on the mains is less than the rating of the relay in this timer, then it will work. But in case the load is more then you will have to use a contactor in between this timer and the mains
