I have a bluetti power station and wanna pair it with an external lifepo4 battery. The aim is to increase the Wh capacity.

1. Is it a good combination?

2. How will I charge the battery since I don't have an inverter?

3. Will I need a charge controller for the battery?

If your location is Lagos, I can look at it for you.
Contact details in sig.

Good evening to y'all, please I need your help. My diy 1kw trips off whenever it tries to power the UPS, but the 44ah is doing well.
Please what could be the problem?
Cc penuelseun dollarnaira

Check the voltage as it tries to power the ups. See if there's a rapid voltage drop before the trip.

madaleeda:
See the battery

Would be nice if you compress these batteries. They are polymer pouch cells and tend to swell as they cycle.

officialfestus:
My build powers my blue gate UPS now, thanks to you all.
Dollarnaira, penuelseun and ewizard1.

Nice!

Welcome on-Lithium-board.

mvphenryeto5:
Bro you are using sachet inverter to power Ac while some people here said sachet inverter can't power a freezer

A true rated power sachet inverter can power AC.

dollarnaira:
With the right mosfets replaced,it will work

Not always Mosfet... could be the oscillating driver circuit is fried, and most technicians don't bother much with that.

If it has visited several technicians and still didn't work, then it's past Mosfet issue.

gifted65:
What do you suggest I do now?

Pay a better installer for rejuvenation.

Trippledots:
The installer did this for you free?? Why are cables flying everywhere?

Meanwhile your system is too small for the load you are putting on it.

A proper installation might cost too much for him.

mvphenryeto5:
Yes

I was glad I didn't!

mvphenryeto5:
There's no how you can enjoy a used sealed lead acid battery cos you don't know how it was used, it might have only 20-30% efficiency left, to enjoy Lead acid you have to buy it brand New from reputable brand

Okay, you meant I should have gone for brand new Lead Acid?

Reading these several Lithium vs Tubular takes...

Sincerely, not everyone can afford Lithium at a go, but my worry is the way these Tubular now flood our market. It leaves something to be worried about.

If not exaggerating, there'll be over 200 different brands of these Tubulars available in Nigeria currently and that's where a lot would simply sink there hard earned money on thrash.

I also started with 2 pcs used Sealed Lead Acid battery few years back before I tried assembling a small Lithium battery for myself and currently see those LA batteries as simply waste of money.

So my honest opinion is people going for these Tubulars should reach for reputable brands to effectively enjoy their invested worth.

800V - 1000V HVDC.

We don't want to start reading news like "Solar Installer electrocuted while working." ooo!!!

I am unapologetically a hybrid fan, till next life, Take it or leave it, standalone systems are gradually becoming obsolete.

E be like you dey produce Hybrid!

Because...

Ferdiwar:
The 1st guy wanted to run it 2s3p or 2s2p.

Yea the 2nd guy is humble and I love the fact that he resisted the urge to step on the panels while mounting them.

I really frown at this act.

jonescosmos:
I had gone to correct an installation last year where an installer connected 2units of Felicity LPBF48300 in series, to 2 Units of Growatt which were in parallel originally.

Imagine this!!!

Samafroxy22:
still available?

Currently not. Thanks.

Johnchrix:
we are in 2024 kindly chat me on what's app for latest prices

Very funny though

Please can this thing be true or scam

I detest that term "fuel-less generator"

maclawrence02:
I've always been fascinated by all these DIY Setups but a total novice. I will like to delve into it, I don't mind paying to get a good graps of it all. Anyone to teach and guide me? I will really appreciate it.

Nice. I can set you up!

Check my siggy!

dollarnaira:
Can u share?

Firstly, the input current at such lower voltage would be higher and require costlier components.

Secondly, the High side Mosfets gate driver might not switch effectively leading to shorting mosfets.

I once successfully modified a TL494 driver based modified sine wave inverter and it worked.

Searching for 12v inverters that would match a 3s Li-ion setup led me to studying the sachet inverter circuitry and I realised why.

dollarnaira:
True bro
I have an msw dat shuts down at 9.45 and the 2nd one 9.78v.

But truth is from 10.5 to 9.78v is roughly 30mins from my test on a 40w load or so.

10.5v to 9.78v is different from 10.5v to 9v
The 9.45v is a better one.

Greenfaces:
I need cells

What quantity and capacity do you need?

luvlyoracle:
I need 12v inverter pls

TBB 12v 1000W available. 170K

dollarnaira:
Buy ooooo
Any 12v will work.
Soure is modified that's all.

A 3s LV is at 9v (3v/cell), 12v inverters would shut down at max 10.5v; (3.5v/cell)

"Any 12v inverter" would work but not efficient.

officialfestus:
I'm skeptical about buying that souer inverter.

I just hope it will work for the 3s battery configuration.

Your best option is a locally built DSP inverter that can be programed to work perfectly with your 4S. No market brand 12v inverter would do.

Greenfaces:
If 15k is not too much for the pdf and getber files for this modified square wave inverter, please discuss with me.

Why not improve to get it Pure Sine Wave, a lot would reject MSW inverters.

mctfopt:
They say a picture is worth a thousand words

I read that line and chuckled.

toscotech:
My inverter is 3.5kva 24v soccer power

How many 135ah lifepo4 cells will get

You'll need 8pcs cell for 24v Inverter.

[quote author=officialfestus post=128559342][/quote]Okay. Yes, you're better off with this.
