Presently I am using UPS model “BNT 500A”. Its working finely but I want to extend its backup time by connecting my (180AH battery )externally. Possible ??

Charging more than one battery can overload the UPS?

The hoffed asked:


I have a normal 1000VA Line Interactive Power Center UPS. I’m thinking of adding more batteries (12V) in parallel to extend the backup time. Will extending too much (like five batteries) cause the UPS’s charging circuit to overload and burn or will it just increase the UPS’s power consumption.

Recommendation on inverter battery?

I have recently bought an 1400KV microtek inverter, need to get the right battery. My current usage needs would be just about 120 watts, however needs could increase and looking for backup time of 6-8 hours. Any recommendation on the optimal battery configuration and pricing would be very much appreciated. Any dealer contact in chennai would be helpful.

Thanks
