Hello,
  • We have a 1750va UPS that's providing power to 3 computers. - It last an hour and 15 minutes usually..
  • UPS is connected to 2x Deep Cycle batteries, both brand new 100ah.
-

Question:
- Can we buy an Inverter with bigger batteries that would last us hours, and plug the UPS into the inverter? would that be safe or a good idea?

would it be safe to do that? we didn't want to plug the PCs directly into the inverter incase of small outages where inverter wouldn't be able to immediatly supply power (which outages happen here daily non stop/often)

Photos of our UPS (THIS IS FROM GOOGLE, OURS SAYS 1750VA)





Any other suggestions/Ideas? Thank you.

NEVER EVER under ANY circumstances EVER daisychain UPS's/Inverters, EVER. If you need more hold time then purchase something with longer hold time and REPLACE what already exists.
Dang, on quora or whatever some technician guy was saying it was safe to plug a PURE SINE WAVE ups to a pure sinewave Inverter but i wasn't 100% thats why i asked here :/ I guess if I use an inverter I have to sacrifice the UPS completely huh?
