Ok, thanks.

feflo:


I think the major challenge will be the charger. It will be extremely difficult to get an effective charger for your 12v 400ah battery bank. It's professionally better to go for a 24vdc system as earlier advised.

Alright, thanks.

Penuelseun:
not small, but will put a strain on the ups if using it for a long time

I experienced the worst side of lithium ion batteries on the 5th of December 2019. It exploded and completely razed my store room.

My observations and lessons learnt will be posted on here later.

agh eeeyaaa... How did it happen? Did u use any unspecified charger or what?.... Damn... A great loss niyen o.. God shall replenish with better package...

Feflo, is this price still valid and should I still contact femi for this?

feflo:


All available, 200ah @ 40k
Converted UPS @ 25k without charger

Contact Femi on 08023662352 or 08165304602

Thanks

feflo:


24vdc 250watts fairly new solar panel @ 35k
12vdc 100ah brand new battery @ 40k
12/24vdc pwm controller @ 30k
650va converted UPS @ 10k
Solar mount materials @ 4k

Thanks

mctfopt:


I like how you make all these super affordable. Great job

Same PWM controller that is less than 5k on AliExpress with shipping.
Only thing I'd buy off him is batteries and solar panels.

Penuelseun:
Sorry about that, didn't the battery have a bms, and how did you charge it before this happened?

The prices are still valid sir.

Femi and Feflo is thesame. Femi is the personal name while Feflo is the business name.

Many Thanks

Yes. Some are less than 5k.

Oh boy!.. So sorry!... I'll show dis to one of my friend that keeps arguing that li-ion is safe yen yen yen....as if there are no risks. But first I'll like to know what happened.

I use a li-ion pack dat was designed without a bms.. Nonsense builder, story for another day...but my only consolation is that it was designed for 16v or so, but i charge to max 14.5v.....or maybe i should just decommission the thing sef.

terrible, and i learnt the fire cant be put off, conventional fire fighting methods like water, foam cant put if off. you just gotta let it burn, till it exhausts its fuel supply.
someone shared a link few months ago, in the usa..the fire service came, and just stood by to let the fire burn out, after isolating the burning structure from other nearby houses

Sorry about that, just got to see this. Lithium as with all emerging technology still needs a lot more attention given to it to operate it safely. We've got lithium in our laptops and phones and none of these two are having issues with explosion after the Samsung exploding battery saga.

I guess the one that got burnt was the one you mentioned here: https://www.nairaland.com/1389975/worlds-smallest-power-inverter/62#79087256

Lithium is the future of energy storage, the technology will get safer and more rugged with time.

OMG. How did it happen? Overcharge I think?

Trippledots:

This is the trick to be safe with lithium without a BMS after a proper building.

What could cause A P C UPS overload and over current lights to be blinking when connected with smart charger.

This happens when the battery is almost full.

Thanks for your concern, i will personally still use lithium but with a lot of precaution.

I was able to put it off miraculously using normal car fire extinguishers.

Many Thanks sir, really appreciate your concern, very well said sir, lithium is the future of energy and we will be unable to avoid it in the nearest future.

Part of the issue that caused the fire.

Thanks

Sorry for the late, tied up with some project, It could be caused by one of two things:

1. Overload light blinking could be as a result of failing internal circuitry

2. The condition of your batteries, since it occurs as the battery is almost full, i suspect one or both of your batteries are failing and the light blinking could be the over-voltage light. You have to measure your battery voltage as it approaches full voltage.

Thanks

It's a pure sinewave inverter. Tested and trusted.
Thanks

How much is the inverter.

ModelX:
Yes. Some are less than 5k.

not all aliexpress items are good product, some are substandard product,, not all that glitters are gold,,
even some fake mppt charge controllers u see on aliexpress thinking that they are original,, when u open up the case ,on the circuit ,yoi will discover that its fake because it lacks thed basic component of an mppt controller

Solar charge controller, 12 - 48vdc 60amps @ 70k

Greetings to the house, I just collected a bluegate ups from my office yesterday to configure to inverter, but there's no battery inside, so it's difficult for me to know if it's 12v or 24v, please I need opinion.
It's a 1500kva
Model number is 1570 va

Bluegate 1.5kva is always a 24v system with 2 batteries.

U can see how big the space in the ups is cos it houses 2 batteries instead of one.

So connect 2 batteries in series and u're good to go

Cheers

Remember to add an external charger if you are using batteries above 7ah on it.

Ok, thanks.
