Router Battery Backup

Easily 10m or more straight, more if you have to follow walls (and you have to with a flat roofed house).

Could you draw it? Or type it like ONT/Router <15m> MikroTik RouterBOARD hAP lite + DVR <15m> 1/2/3 CCTV camera(s).

Your average ONT, router, hAP lite and CCTV cameras barely draw any power compared to your DVR probably being on the heavier side of power draw, depending on the amount of drives you have etc.

I would say, depending on your exact setup, running a bluenova for the ONT and router is overkill. Look for something cheaper, like a gizzu or even a sherlotronics 3.2a CCTV setup with a cheap SLA battery. Implement forced loadshedding once a month to keep the battery alive, and you will be fine.

Difficult to comment on what one can use the bluenova's on, as there seem to be quite a bit of contention around if they are indeed able to be charged by a normal SLA charger - unfortunately quite a few of the non-inverter solutions out there are geared towards SLA batteries and not lithium/lifepo4 or whatnot.

House is sideways to street, DVR/14-analogue cameras/small switch at back <15m> Openserve ONT + router <10m> DVR/8-analogue cameras at front.

Well, I already have 2 of the 8ah Blue Novas and a 11ah one.

I'm a bit gatvol of SLAs and the premature deaths due to extended outages. If I am not home during a long outage no one (I have to rather do everything myself lol) will switch the UPSs off so they will run low, and even if I am home I want to keep it running till it can't without killing the battery since the LiFePO4 can apparently do 2000 cycles going 100% DoD.

I am aware of that contention. Maybe I should just run my Eaton UPS with the 2 x 8ah Blue Novas in it till it goes low, and see if the UPS will be able to charge it and then I probably don't have to get anything, but it would be more efficient if not going 12V > 240v > 12v.

I know my UPS could do at least do 5 hours with 2 x 9ah SLAs when they were still fresh, never tested till low level beeping started (and I was never home when it did go all the way down).

Quite a few cameras then. Would make sense to plop the two 8ah ones in your UPS, to feed the DVR/14 camera side, then get something cheap for the ont+router, or even go passive POE,given the draw (<500mA?) and the distance the voltage drop on 15m 22awg is like 6-7%?

Then you still need to find something to run the DVR/8 setup. You still have a 11ah to play with, but you would need to get clarity on how much those cameras draw, cause then you could get a 3.2/6.4a sherlo to run this side of the setup. Once again, ignoring the issue about how the bluenova would handle the SLA charger.

Alternatively you could get a proper external charger and simply charge the stuff externally after a loadshedding event.

The one advantages of the SLAs, is that you could screw up and simply have to pay R200 odd a pop to get up and running again, but one cannot afford to take the same kind of risks with a bluenova, as they are simply too expensive to replace every time...
 
Has anyone with the Ratel 860p or 430s hooked up the unit to a solar panel for charging?

Interested in hearing your experiences
 
For anyone looking to extend their DC to DC cable for the UPS, the below type of plugs fit on the router and ONT but not on the Ratels.
I will post back when I find one that fits on the Ratel UPS, then all that is needed is a piece of cable to your desired length.

These fit the Ratel and the UltraLAN:

Hi guys. Need help choosing a ups to get me through 2 hours of loadshedding.
Im currently running a telkom ONT device (12v, 1.5A) and the telkom supplied D-Link router(12v, 2A).
So total power per hour is 42Wh.
I wanted to purchase the Ratel 860p from Sinetech however they have informed me that it has been replaced by the Ratel 8100.

The 860p shows that it can run at 40W for 5 hours however the more expensive and replacement 8100 states that it can only run 20w for 2.5 hours. See links below for the full specs.
860p-> https://sinetechstore.co.za/wp-content/uploads/2020/07/OmniPower-Ratel-Micro-UPS-Range.pdf
8100-> https://sinetechstore.co.za/wp-content/uploads/2020/09/OmniPower-Ratel-Micro-UPS-Range-1.pdf

A guy working at Sinetech says the specs are incorrect and that the 8100 should give me 40w for about 4 hours.

Additionaly on this website it shows as 40w for 10 hours.

Can somebody with the knowledge read the spec sheet and advise what the correct backup time is.


Thanks in advance.
 
Friend and I have made over 60 x 4-battery lithium-ion 12 volt power supplies that we sell for R1400

It consists of a 12 volt 5 amp mains power supply. This charges 4 lithium-ion batteries with a balancing circuit, current limiting and charger. There are 2 DC power connectors for a ONT and router

This can maintain service for 4+ hours

Price is FOB Cape Town. R100 for Postnet anywhere in SA

It well out-performs the similar unit sold by Takealot for the same price

I just realised that I can plug my battery packs into my UPS instead of directly into the power socket. That should double the time to 8 hours easily.

A regular UPS cannot supply power for a much longer period than 45 - 60 mins. The components get hot and the thermal cut-out engages

An inverter is what you should have

Yeah ...ok but mine lasts for 3-4 hours so whatevs.

Does Postnet go through sapo at all?
Otherwise, I guess someone like aramex was too expensive?

Postnet does not o through SAPO, they do their own couriering point to point. Have used them as recently as last week when I bought a switch from CPT and the item arrived in 2working days (to PTA)
