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 grin grin 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.

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. cool

I really frown at this act.

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!!!

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!

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.

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.

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.
Technology Market / Re: Diy Lithium Ion Like-minds by ewizard1: 7:32pm On Feb 23
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.

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.

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

I understand bro. Those things are stupidly expensive these days. Your battery would be fine with the "Balanced version" BMS.

I know quite a few of you here build batteries and know your way around these cells.

That comment was for some newbies I see trying to build.

Peace.

By "Balanced Version", it means your BMS has a "BALANCER" integrated which could be a passive balancer.

All I point at is "Get an ACTIVE BALANCER" BMS integrated or standalone.

I know but since inverter can be charged with Nepa, can't solar energy charge it too?
Both can.

Laurene:
can I use solar to charge the inverter?
You actually use solar to charge the battery.

Love800:
What do u mean by inverter AC and inverter freezer?
Does it mean the main inverter dat powers the other appliances is different from inverter AC and inverter freezer?
Inverter - A DC to AC equipment that converts DC power (Battery/Solar) to AC (Alternating current) power which is required by your home appliances to work.

Inverter AC(AirConditioner) / Freezers - Appliances that consumes lesser energy and thereby efficient to be powered by the (DC-AC) Inverter.

A Highbridge inverter won't need a charge controller. Use the budget for charge controller to add up for a Highbridge inverter.
My 1cent advice.
It's... Hybrid Inverter.

You need to experience it.

With proper initial balance one is still safe.
What lithium hates is overcharging and depth of discharge. After all no lithium batteries can have exact voltages among themselves. No matter how small there is always a safe difference.
Okay.
