APC 1500VA OR 1300VA Backup System?

Anonymous user · ‎2021-06-29

Hi all,

I'm planning to buy a backup system, but I do not know which one to get. Please give me some input.

What I am planning to use it for:
1) I have a SONY LCD TV 40"
2) PC
3) Linksys Router
4) Ethernet External HD
5) Another External HD that I sometimes turn it on.
6) A Printer that is hook onto all the time (small printer)

All these six (6) devices will be plug into the APC Backup System. Which one will work best for me? Last week, I encountered two electric shortage within my apartment, because of the Microwave and the Heater turn on. Therefore, I need one of these APC.

Will APC 1300VA work? Or it doesn't have enough WATT for all of my six items above? Thank you in advance ...

Aeries

The fact that you are having "electrical shortages" in relation to your microwave and heater competing for power, leads me to beleive your electrical circuits are undersized/over taxed for your load. Adding a UPS to this configuration would certainly help, however, you will likely notice the UPS clicking due to power sags.

I would recommend a UPS which is Line Interactive and capable of correcting under voltages without using your batteries power. This way the battery will remain at 100% of it's capacity in case a complete outage does occurs(tripped breaker).

Based on the varying load listed above, I would recommend atleast a 1500va UPS. Without knowing the exact specifications of the load equipment, it would be difficult to confirm whether or not the 1500va UPS could support the entire load.

Any idea how many watts each of your load pulls? Most importantly your TV, I can figure out an estimate for the rest. Also, if there is a power loss, how long would you like your load to stay on for?

Wow, been a few months ago. I boutht the 1500VA. Plug all the accessories into the backup. I occasionally have power shortage in the apartment, because of the heater, hair dryer and microwave. LOL.
But the 1500VA keeps my 40 inches LCD TV alive and my computers. That's good.

The drawback is, once the power goes out, the battery only support 18 mins. LOL. But that should be enough time to turn off everything or switch the power back on.

GREAT ... 😃
