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.

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

alright, I think I'll buy the souer.
Thank you for your input.

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.

thank you for your contribution. 🙏

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.

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

Can u share?

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.

Hmmm
Thanks

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!

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

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

Good morning boss, did you use insulation for the covering of the pack?

Yes

did you also use something like this?

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'

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.

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

Hard back cover is good
I have used it too

for the separation of each sseries, I use a carton.

I plan on casing with junction boxes.

Hello,

Can this be connected to the the house as a whole
And can we get it carry more load and at what cost
