UPS / Inverter Help - For Network and PC

[ghostRgg]

So I am honestly at wit's end with random power issues, outside of loadshedding it seems there are some on-going problems here in Durban. Decided to finally look into some solutions to make life a little less miserable.

Problem 1 - A device to keep my Fibre Box, Switch and then Router online. I was told a UPS 850VA (Like this). I am looking to keep this on for at least 2-3 hours since that's how long most of these outages are out for 6 hours would be great, but the price jumps I assume?

Problem 2 - This is where I get a little more lost due to calculators and such. I need something to run my 25" Monitor, 750W PSU PC (Runs normally at around 450W Load) and the network switch I have in this room. Looking for something to power this for around an hour or so.

I haven't been able to find a calculator that really helps work out wattage for PC's and network gear into VA or Wattage loads for a UPS. So any help will be appreciated.

If all your gadgets run on 12v then rather get something that doesn't invert - they're more efficient. Just check the combined amps required for all 3.
Something like this:

PSU CCTV 12VDC 3A

Power Supply Unit with Battery Backup • 12VDC 3A UPS • with Battery Compartment for 7Ah Battery (Battery NOT Included) Overview Features Input voltage can vary from 90VAC to 265VAC without affecting the output voltage. (output voltage remains constant) Input and output fused Short circuit...

Just add 12v gate motor battery

I will have a look, I don't trust my self enough for that but I guess I can learn easily. Would probably save a few bucks for the router and network side of things. I just hope this one box is 12v.

6 Years back I bought a modified sinewave inverter (12v system) and 2x 105Ah batteries, and all this load shedding nonsense isn’t having any effect on me, I power all electronics from it, and have no downtime.

I started of by measuring each device, and then added everything. I switched everything off and monitored the complete load while switching it on. I monitored everything over a month and came to the total I need. My setup keeps everything running for 6hours.

I got myself few of the LED light bulbs that have batteries in, and if I need light, I have in every room.

(Explora, TV, Soundbar, Sub/w, Apple TV, PBX, Yealink BaseStation, Efergy Hub, ONT, Router with WiFi, Switch, NAS, pfSense, LTE Router and 2x electric recliners.)

Get an inverter with some deep cycle batteries.
