Router Battery Backup

[Tomtomtom]

Can anyone recommend a decent quality +/- 200W inverter?
I just need to run my printer and maybe a quick boot of my desktop to get a file from time to time during load shedding and I’ll get one of those 7Ah lithium gate motor batteries to run it.

Do you have an old PC UPS lying around? They aren't designed for > 5 min runtime so you might want to add a fan.

Not sure about the charging situation and as noted the current draw could be too high for lithium. Maybe a ~50 Ah car battery is in budget.

Link to the battery please?

Got the battery at the same place as the inverter - Brights ‘brick ‘n mortar’ store.

Sorry this might not be the best place to ask this, if not which thread would I do better asking on?

Just buy a cheapie ups and put 2x LFP drop-in replacements in there. Cheap (well, maybe not so cheap these days), quick, easy. (The 7Ah ones you mentioned, but a UPS will need 2, which should solve your high-current issue)
Caveat - remember to balance charge the batteries by connecting them together first - else they won't even out and you'll get rubbish runtime.

Thanks.

Confirmed in this thread (Gizzu GPS300 or Ecoflow River
https://r.tapatalk.com/shareLink/topic?share_fid=11467&share_tid=1217647&url=https://mybroadband.co.za/forum/index.php?threads/Gizzu-GPS300-or-Ecoflow-River.1217647/&share_type=t&link_source=app) that the Ecoflow is not suitable for inline use.

I looked at the Delta Max and even the new Delta 2 but their UPS mode (EPS as they call it ) takes nearly 30ms to switch over from mains to battery.

Your laptop should be fine but a desktop or server needs something in the 12ms range.

I've ended up with an overspecced (and probably overpriced for what it does) solution but on the upside, it works. For the load that I'll be putting on it (around 60W) it should run for 6-8 hours on the 12V/50Ah battery.

12V/50Ah battery (see pic) connected to an ACDC 600W Inverter (built-in 10A Charger and two 3 prong style output plugs) (Link) - permanently connected to power - when LS hits, seamless cutover and the switches (Unifi US-8-60W + Unifi US-8), 4 x AP's (2 x UAP-AC-LR + 2 x USP-AC-Lite) and Unifi Cloudkey don't miss a beat - when the power comes back on the inverter starts charging the battery again - so far, after a 2 hour LS session, the battery recharges within 40 minutes.

In the end, the solution cost me 7K (4K for the battery, 3K for the inverter) - the cost can likely be brought down by going with a smaller battery and a smaller inverter but I ran out of time and patience looking for a cheaper appropriate combination that would do the job.

It's rudimentary though in terms of being able to monitor (can't monitor increments of charge - it's either 'red' (charging) or 'green' (fully charged) and the inverter will beep and shut down if the battery is depleted.

Overall, needs must and I'm happy that it works (the network stays up and fully operational) but it's certainly not the most cost-effective solution I could have gotten nor does it give me the option of fine-grained monitoring and management.

This could look after a TV and streaming stick for load shedding.

200W? 15.6A?
I would assume he meant 200W at 230v = 1A or less?

200W is 200W. It doesn't matter if it's the AC side or the DC side, a watt is a watt. The battery has to supply that 200W. The battery is 12.8V. 200W divide 12.8V = 15.6A DC, but yes, it would be 1A on the AC side which is irrelevant if the battery cuts out.

Nope he means 200W coming out of the battery -- usually around 13V. It's the battery that has a discharge limit.

where did you buy the inverter and battery?

Looking for a UPS to power my internet for 4 hour loadshedding. 9v router and 12v ONT box. Are these any good? Any other suggestions?

I use the Netogy on a 12v router and 12v ONT, I've not seen it drop lower than 50% during a 4 hour session. Recharge to full takes about 90 minutes.

 

[Dade Murphy]

Thanks. Any idea if it can charge a laptop with a USB C input? Or any other UPSs in general?

In theory, it has a 19V output, just not sure there's enough capacity. It's like trying to charge your phone off the router UPS. It will charge your phone, but then you have an empty UPS with no internet.

Rather get a USB C battery bank with Power delivery, just make sure the output wattage is sufficient to power or charge your laptop

 

[airborne]

Interestinglu I see Winx sells cables for USB C to many different 19v laptops, even if you have an older model you can power it with a USB C Power delivery battery bank or power supply.

I have 2 of these Netogy jobs - one handles the router and ONT, the other powers my laptop - on a permanent basis. My laptop (HP Pavilion, 19v input) doesn't even have a battery installed, but it uses a conventional round power plug with central (sense) pin for input. I don't know if you could achieve the same via USB C - you might have to mod the cable so the laptop thinks it's the official charger/power supply.

The Netogy keeps my laptop alive for a 4 hour loadshedding session.

Would not mind a mini ups thingy to keep my laptop running furing load shedding. Needs 19 volts ....
