i'm just thinking about the impending power crisis next year; we intend to buy a genset, but i'm thinking a UPS can will the gap between the switchover from Meralco to genset.

Despite the 1-2kva rating, backup times for APC and Eaton models(as is) can only provide <10 min backup time, which i think is just too short. Using APC and Eaton's runtime calculator, to provide for 10-15 min of backup power, i'd either need to get a really expensive model(Eaton DX2000) or one with an external battery pack(APC).

imho, parang hindi sulit yung price-vs-backup time ratio, so i started this thread/ in parallel.
