I'm not a fan of those UPS for backup power. They were designed to keep a a PC or similar device going long enough to shutdown properly during a power failure, not as a continuous power source. And the batteries need replacement every couple of years.

My issues aside, it only has about 40Wh of power so will keep the NUC going for a bit more than an hour.

Hi, what make UPS do you have?
Asking as I have a RCT 3000 VAS Line Interactive UPS and during load-shedding, it only lasts about 80min.
Only thing connected to it is
1. Rain 5g Modem
2. Dell Screen

Can it be faulty? It was only bought in May'21

I would always be wary of using a UPS for long run times. While they will work most people don't realise they are only built to run for 30 minutes, after that with the power conversion involved you will be eating below 50% of the battery. Once that starts happening you will only see it last a few months before it can no longer last more than 20-40 minutes before it completely shuts off.

That being said. It is a 3000VA at 2400W, which should really handle the 100W or so that a screen and router would use. (ignoring the long calculation involved to work out the times)

Saw those things go for R6k or so. Would rather recommend a cheaper inverter setup to some GEL batteries.

You wont be powering that PoE injector, you will be powering the PoE device itself, what device is it and do you know the PoE standard it uses?

I don't have any POE experience but your pic I can see "30V" and the spec on gizzu is 1636543306428.png

Hi, thank you for the reply. It's a small dish, mounted on the roof. Don't know what the standard PoE is.

I was thinking the same thing. Common sense is telling me it won't power the dish but I don't have a clue about these things lol. Just looking for a UPS that will keep my internet running during loadshedding.

I hear you lol. I've heard of "active" and "passive" POE. Whatever that means.

OK folks, we're looking for a DC UPS with 30V POE.

Well not necessary, the voltage readings that are listed vs the actual PoE standard are two different things. If it is the PoE af standard, you will need an af standard PoE aka 48v. Even if the device is only using 30v. Regarding backup systems, it's really not cheap or possibly to do a simple 48v backup system, you either have to go custom or just reach into the 220v power backup route.

Any chance you can give us the model name of that dish?

220V power route? Not sure what you mean by this.

Power the brick in your hand with an inverter and battery. Something like this. (only 295Wh)

or the more conventional route and power your TV etc (1200Wh):

Not sure on the exact model. All I know is that it's Cambium.

Oh noo... most of the Cambium stuff is running on 802.3af PoE which is a 44-57v but is a 48v standard. We ( @Ghostfibre ) are actually busy trying to build a custom solution for this sinch majority of the neighbourhood watch systems are all on 802.3af PoE cameras and wireless points.

It's going to be something like a step up from 12 or 24v to 48V and then feed that into a PoE injector or switch.

What @wingnut771 said. An actual inverter and battery system that outputs 220v.
