hi all,due to lesser rain fall in our native we have power cut for whole day:(,Thinking of buying a inverter which can provide backup for a tv,stb,pc & 5-6 cfls for 4-5 hrs.
Need a vfm solution and pure sine wave inverters is preferred as cfls start whining:annoyed: using non sine wave ups.

we get power only for 8-12hrs will this be sufficient to recharge the batteries.

8-12 hours of power at a voltage where the inverter doesn't switch to battery backup is usually more than sufficient to charge the batteries. The time for a full charge depends on the number of batteries and the AH rating. Google for inverter battery charging calculators. Not sure about the recent Sukam Sine wave inverters, but those from a couple of years ago had a high pitched metallic whine that remains audible all the time (even when it is delivering power via the mains) along with a rather noisy fan that operates whenever the inverter is charging and/or needs a cool down. I'd suggest taking a test-drive from the dealer. Keep in mind that what sounds quiet in a noisy store will sound a lot louder in a quiet home.
 
Friend told Microtek are worst so stay away from it.

Can any one suggest good models from Su-kam or APC ? Is there anything good in 10000 Rs range ?
 
@ivhere,how much did pay for the inverter & batteries.Can you post the how much backup you are getting with what capacity battery.

Sine Wave ones from APC are available in 650, 850 and 1000VA range.
I use APC BI850Sine Home UPS with Exide IT500 battery.

The budget 10k is for inverter only or complete set with battery?
 
ivhere, backup calculation guide is really helpful.
Btw, i'm using luminous 800VA pure sine wave inverter with okaya 120Ah tubular battery. currently using it for 3 cfl's & 2 fans.
Total costed me @ 14700/- with 36 months warranty.

scudmissile07, i'll suggest you to purchase 1.5 KVA inverter as your requirement is high and may also increase in future.

Don't know about newer models but earlier models were good... Still using one since +2.5 years... :)
 
guys,now one more problem i forgot to mention in the earlier post.The input voltage we get is around 170-180v during 3 phase power(for 4hrs) & 210 -220v in single phase(for 5hrs) it fluctuates in between,will it able to fully charge the batteries(2 *100ah)with this power & voltage input.
 
Inverter should work fine at 180v and it only needs single phase power. Get the inverter installed first and if you face any problem due to voltage problems you could buy a stabilizer later.
