The Alternative Energy Thread - Generators, Solar, UPS, Wind

[Zyrak]

i use DESI made ups for all purposes, my DSL as well as wifi router, charging laptop, lights, fans etc.....and working smooth. never feel any problem at all

[faiz.aslam.121]

I use a desi ups too
When I first got to pakistan it fried my genuine laptop charger, got the capacitor replaced to a more heavy duty one which works awesome now:p
I can run LED-tvs, 2 laptops (without battery) PTCL wifi routers and 3 energy savers for roughly 3 hours and that has been confirmed by the installer.
I believe it is all about installing it properly and fine tune it too. Good luck:)
I've got 1000 watt battery so yeah.

Branded UPS are dry battery ones. Which will give you approx backup time of 20 mins on full load and an hour at nost at minimal load.

On another note DONT EVER ryn ur expensive led/lcd and hifi systems on desi ups. It has been discussed alot search for it.

my branded Digitech UPS fried my laptop charger!! Thank God nothing happened to laptop!!

[waqastariq]

Thank you for all your responses, but none answers the questions I asked.

My question is how much backup time (estimate), will this APC UPS (750VA) give me? What-if I go the extra mile and buy this one? APC Smart-UPS 1500VA LCD 230V : Power Accessories | Dell UK the backup time will double?

Also how long will the battery last, I mean before I have to change them again?

That is not true. When Wateen launched 5~6 years ago they were giving away a UPS with the device for 1,000 extra, I had this device (it had dry battery) untill last year (when the battery died) and it used to give a backup of 8hrs+ when I ran my router on it.

Brother read my reply again, I said with full load it will give you maximum of 10 minutes while at minimal load it can give you an hour. But with very low load as you mentioned that you were running only router than yes it can give you such backup which you claim.

I'm also looking one for my Router and Access Point. I heard that desi UPS's have square waves which is dangerous for electric appliances. Correct me if I'm wrong.

Here is the thread.....

Honnex ups is the best !!

[abzia]

Brother, If the backup time is low, battery is the culprit, not the UPS. However what I use and suggest is a DC UPS for this purpose. Since router runs on DC, there is no DC-AC-DC inversion required through UPS inverter, hence less discharge for the same output. OK, now thats what you need to do.

1. Get 12V-9Ah dry battery, will cost you around 1k max.
2. Connect it to the same UPS you've got now.
3. Take terminal out form Battery directly and plug those into your router.
4. Enjoy the DIY satisfaction

Additionally:
1. Check polarity and rating on your router's adapter, It should be 12V (otherwise a little more circuitry is required).
2. Check battery charging voltage it shouldn't rise above 15V during charging, thats how much usual 12V electronics can bare. I'm using my wi-tribe wifi router at 14.5V, and its giving better coverage than its own adapter.
3. It should give you around 9 hours of backup if router is rated at 1A. If you need to extend this further, add another battery in parallel.

How about Wingle?

I simply plug it into the power socket connected to a typical residential Homage UPS. It draws very less power! Occasionally plug my lappy to the same UPS without any issue.

[versatilegenious]

Homage UPS is the best in buisness. We have 13 users of it in our family and alhumdulillAllah everyone is satisfied with its performance.

How much is the battery used? Because i think may be battery is the culprit in your case.

[cooldude1987]

any1 tried it yet .. to me it`s best in the market as compared to Homage or other brands

[Vajih102]

APC is the best brand in the country man! You've made an excellent choice.

[saadzzz]

AGS is the best......

[Siddique18]

AGS Battteries are Best As compared to Other Available in MArket.
