Insightful write-up, I can't find where you connected the cooling fan on ur diagram. Pls clarify. I really want to try this ASAP. THX

CharlesPhc:


The space that would be created after you remove the 7Ah battery inside the UPS, position a cooling fan there.

Why you need a cooling fan.
Because a UPS was not made to run for a long time with power, the transformer may get hot so you need the fan to keep it running under normal temperature

Dymaco:


send me the picture of thé complète set up.
that is the external charger, battery and ups connected together so as to enable me construct mine

and how long will it take to charge the battery 100%

CharlesPhc:



I just opened up a unit in my study to show you a sample of the setup. Don't mind the wires, had to pieces the UPS for you to see the fan inside.

Pics uploading soon...!!!!

happen2:
Can it be used to power freezers or fridge. Please I don't see any fan in the picture, pardon me please.

CharlesPhc:



I can show you what to do online. Its very simple and easy to setup...!!


Ok, i will share a number to call just a moment...!!!

JAMESM1:
pls drop your number so i can reach you

CharlesPhc:
Things you would need:
1. An old but working UPS (650VA or 1200VA) - Free from any computer shop or technician
2. A Deep Cycle Battery from 38AH (Keke Nape Battery N9,000) to 100AH (Truck Battery N20k)
3. A battery Charger N6,000
4. System Fan for cooling of Unit N200

Total N15,200 or N26,200


That is all you need...!!!

JayJustus:





give me your contact bro...wanna speak with you

CharlesPhc:
Connect the Battery Cables from UPS to Battery Terminals (Red to +ve and black to -ve).
Connect External Battery Charger to Battery Terminals same (Red to +ve and Black to -ve) When the battery charger is powered on, it would charge your battery.
Connect a Power extension socket from your UPS outlet (the back of your UPS) to your TV, Radio, Computer etc.

Or contact an electrician to locate your ceiling fan, power socket and bulb lines from your building distribution box and connect directly to the UPS

guy1234:
I have a couple of questions:

1. Is it a d.c fan or a.c ?

2. Car batteries are starting batteries not deep cycle ? How long will car batteries last in this setup.

investnotspend:
Nice one OP great job and thanks for solving peoples problem I just got your contact ,do you do WhatsApp on this number so we can communicate with ease ?

redcap:
OP, if you really want to help make a short how-to video on,we can even pay some token of appreciation.

CharlesPhc:


The fan is connected to the battery with a switch. The cooling unit is required when the AC current is out.
Car batteries have been tested with this and it worked perfectly. on my initial setup, i used a 38Ah (batteries found in keke tricycle) and it worked.
But deep cycle batteries are preferable

carblognaija:
I have a similar setup I have been using for close to 2 years now. Can someone pls point me how to upload pics here so I can share my setup.
OP, I stay in PH too. I'll like to know more about the webcam setup. How can we connect?

phoenixy:
Thanks for this wonderful piece op, you didn't mention how to stop the beeping sound on the UPS when using the batteries.

Secondly, how is it possible for the electronics circuit in the UPS to handle so much loads e.g fridge and TVs, when it is designed to be used for low power consuming electronics?

Pls kindly revert.

CharlesPhc:


Very good observation on the beeping sound. I pulled mine off completely so i dont hear the sound of the ups beeping.

I didnt mention fridge as part the appliances to connect

Then i also mentioned a 1200VA ups for connecting more devices
