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

Penuelseun:
most inverters will go into over voltage protection if fed any voltage higher than 15.5v, the souer inverter at 3s config is your best bet if going for msw

ewizard1:

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.

ewizard1:

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.

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.

ewizard1:

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

ewizard1:
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:

Can u share?

ewizard1:

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.

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.

ewizard1:

Nice. I can set you up!

Check my siggy!

akpota:

Thanks.

eghos12:
done

officialfestus:
how's your setup fairing?
How best is it compared to a powerbank?

eghos12:


Have not used it yet. I want to arrange an array with it. Just got a pwm yesterday, I still need an inverter.

officialfestus:
Good morning boss, did you use insulation for the covering of the pack?
Cc dollarnaira

dollarnaira:

Yes
Just to keep the batteries from dangling

officialfestus:
did you also use something like this?

dollarnaira:

What exactly do want to achieve?
Used cotton clothes can be cut in different ways

officialfestus:
did you also use something like this?

officialfestus:
boss I just wan they on a safe side, I plan on using hard back book covers.
Thanks for all you do boss, you're a life saver.

dollarnaira:

What exactly do want to achieve?
Used cotton clothes can be cut in different ways.

The most important part is to get good insulator for separation of each 's'

dollarnaira:


U need sth like this if you are not casing your batteries.

officialfestus:
I plan on casing with junction boxes.
