Anything with 12V to charge a qasa rechargeable fan?

no 12v unless you buy two of the 44w, connect them in series

Drgreatone:
Following!!! Mind to tell us the solar company u working with? 😁😁😁

Sako

OHIsIManuEL:
Is this on jumia?
Please send link to this

you can get it in any online store or physical store

iamlammy:
Do you use this personally? How well does it blow and is it durable? Will you pick this over the qasa?

yes I use it that's why I'm talking about it

oladele239:
This is only DC while the qasa runs AC/DC.

no it is ac and dc, the breeze na die

noobody:
Brand biko?

I prefer his 25w with metal blade, this same company with qasa

feflo:
Yes but it's majorly charged by the controller which has been set to 27.6v

ok

feflo:
Migrating from two quanta 200ah to 24v 5kwh lithium

can this inverter charge the lithium battery

Let me be defining some terms. To make this log easy to carry newbies who will be learning while following up

1. H-bridge /full fridge
Basically a H-bridge is a type of switching topology that mimics the Shapes of a "H" it is characterised by a high side and a low side.

When we say High side, this section, doesn't receive 0v directly from the ground or negative of the battery..

It "source" is connected to the drain of the Lower side MOSFET.



2. Push pull
this is a very popular topology used in inverters starting from the days of square wave -modified- sine wave (yes some sine wave inverters still uses it)

It consists of a transformer with a 3 terminal primary winding.
12v-0-12v (the transformer has 2 12v windings in 1. It has 0 as the common point)

3. Drivers/buffer
A driver/buffer is simply a power amplifier/amplifications stage that Receives signal from the oscillator circuit and sends it to the MOSFET (the MOSFET bank)

4. Totem pole:
this is an amplifier/type of drive circuit that uses 2 transistors (bjt) to increase current and drive voltage too.

It usually consists of an NPN and PNP transistor.


5. Oscillator:
This simply the part of the circuit that generates the on-off signal that operates the MOSFET bank.

I have included pictures of a H-BRIDGE and totem pole

Obnoxious2001:
my contact is in my signature

ok

Obnoxious2001:
Definitely.

that's good, how do we meet

Obnoxious2001:
This is more of a feedback problem.

can it be rectify

Obnoxious2001:
Yes I do

I have one that has low ac output voltage,it read 220v on the screen but if you multi meter to check it,it will read 125v

Obnoxious2001:
Happy new month pals.
The time and moment has come .

So let's take it gradually and slow.
I definitely know folks who will like to carry out their personal repairs will be grateful I started this thread.
(Please feel free to ask and post your problems as well, If e pass my power, I go ask SNR man)

We will be starting with Error #bp
(I have used #the_error_code so it can be easy for you to find them when you search for it on the forum)

#bp = battery not present.
This is caused when the inverter can't recognise the battery it has 2 likely causes

1. When battery has been completely drained (some folks still ignore settings the right low battery voltage for the battery. Some will use lead LVD for lithium)

2. When their is short circuit in the inverter

you're doing well,do you repair sachet inverter
