I have the same setup but I power the router and fiber box directly from battery.
No inverter used.

I tried to UPS route. It's highly inefficient. converting the UPS 12V battery to 220V. Then plugging your router adapter in there to take it back down to 12V!.
I've solved the issue by simply powering my wifi router and Fibre router straight from 12V in the first place! The cheapest , most reliable option is to use a Alarm or CCTV backup system. They go for around R400 (Excl the R190 battery) and will provide power to your routers for roughly 6-7 hours!

Simply cut off the routers Power adapter power point off (or buy a new lead) and screw the two wires onto the product below. Voila that simple.

Here's a link to the product I'm referring to:

I need to look at this, does anyone know if it could work for ubiquiti devices? (Will need to get home to check out adaptor ratings etc)

To keep my internet available, I need to keep the ONT, a USG, and 8 port POE switch which feeds two Poe aps running. If I can somehow also power two of my Pi's, it could be awesome.

While I know a UPS is the easy solution , it could also power my CCTV then, I don't have space to put even a Small UPS in the room - I don't want a UPS in a cupboard.

POE uses 48v, that could be a problem. I have POE security cameras on the system.

I use a 220v UPS, I know it is not efficient, but I just use larger batteries.

For just a modem and router the 12v solution could work well.

I just want to reply to this again because the assumption is actually a little irritating.


This is the VUMA unit and ASUS router that's being used.

Maybe your unit needs a battery replacement or was not fully charged. I dunno.
Or it could be that yours just doesn't hold a full charge for too long and drops quite significantly even after a short period of not being charged.

Have you bothered to check the battery levels (as below) when you make use of yours?

Inverter UPS's like this one use a lot of power, even when there is a small load.
They hammer their batteries and so after a short time the batteries are dead and will produce little backup time as is cited in this post.
(This is why you see so many UPS's being used as door stops or forgotten lying in the corner)

Has anyone used a Midas charger as a power supply 24/7 though?

I've only found these charger options... Still unsure whether to throw R4k at a backup battery in case Im not around much longer.

Alarm/CCTV backups up to 3.5A..nothing higher - R400
Midas charger 5A=R330.
Ctek charger 5A=R1800.

how is it connected to the fibre box and the router box as each has its own power point which has its own plug?
 
what is the red item? and how does each thing plug into each other when the power is off, and is that a normal plug end of the multi plug which is plugged into the white plug of the inverter? multiplug is a good idea. there are so many battery chargers on midas website to choose from, which do you suggest?

A bit of a kludge but it gets the job done.

does the red+black wire that goes from the battery charger to theinverter come with the battery charger, and is that a normal 2 prong black plug on the other side of the inverter? can this run a router and fibre for 2.5

Red is battery charger from Midas. Cheapie 4/6 amp. Clips from inverter straight onto battery. Normal white plug into uk plug on inverter . Clip charger onto battery when power is back for an hour or so.
 
I have a standard Tescom 700va UPS I use to power my routers during LS. Is there any reason why I shouldn't connect a second battery in parallel to increase the standby time? @Chuckmyster @Geoff.D maybe you guys know?
 
I'm trying to figure a way to build my own backup battery system considering that a UPS isn't as efficient as running the router and ONT straight from the battery. Laptop charger or DSTV explora/pvr power supply with a dc to dc step down converter which will keep the battery from over charging when the battery is full but I'm trying to figure out how to have automatic switchover without losing power. :unsure:

Maybe I should ditch the dc o dc step down and rather use something like this :unsure:
