No stress your self the best option remains to buy a real brushless fan.

If you decide to remove the fan, it will affect the inverter. The inverter is designed such that it receives signals from the fan (around 5v). It's through that signal is able to tell when a fan is connected or not.

It seem lot of folks are complaining about the fan noise, there should be a way out anyway.

Experiments and give us feedback anyway

I have made my research and you're wrong chief.

I'm not disconnecting the fan totally, I'll only run the power line of the fan through the governor. The fan has 4 wires. The sensor and signal wire are still connected to the inverter

So if it can only lower the speed of the fan at night, I'm okay cos night is my only issue.

Exactly. Stucked at highest of 400w on a very good sunny day? On top say I get big panels. A supposed 1260 PV 420wx3

bassdow:
Wouldn't a resistor in series or a standard (or Zener) diode do the work ?

Rather than completely disconnect the Fan, you limit it's voltage so it runs slower.

Most times, when a device relies on Fans to get cooled, they don't often have (enough) heatSink to dissipate that heat. You better off with a slow fan than completely switching it off.

Assuming you got an external charge controller, we for use the load's timer so it only comes up on set time.

200ah is around 354k
300ah is 442k

fuckboys:
putting expensive brushless fans that would still run 24/7 on high speed.

This is actually the best cos it controls the speed using ambient temperature, lowers the fan noise and will also prolong the fans life cos it won’t be running at full speed all the time anymore.

Pls where can one get this battery? Original

Gshems:
that's lead acid for you. When I was using 100ah I had similar issues. I thought it was my charge controller but na the battery dey limit the current

Obnoxious2001:
Your idea actually works if it's a 2 pin fan(just + &-)
What you have not considered is that the fan needs input voltage to to be able to
Send signal and it needs to receive signal too.

Red = +12v
Black= -12v
Yellow= tach signal from the fan
Blue= speed control signal


A better approach will be to use an external PWM signal to control the present fans

I am quite sure the device you ordered will likely connect the power to the fan when a certain temperature threshold is met

prince4pro2:
Thanks for this eye opener. I will soon join lithium.this month is exactly I year I started this journey after discovering this forum

capnies:
All original Sony tvs atleast I know from 40" uses external adopters.

But you'll need boost converter

fuckboys:
No, what the governor does is increases voltage to the fan from 1-12v and at constant current of 1a depending on the ambient temperature.


I’m 100% certain it’s going to work.

Yes there’s yellow wire a tach sensor, this actually sends signals to the inverter to shut down in case of fan failure

Yes there’s a blue speed control wire, now this wire doesn’t matter anymore if the power to the fan isn’t controlled by the inverter anymore. This wire will remain and tell the inverter to send full 12v (highest speed) to the fan which the inverter can’t do anymore cos it doesn’t control power to the fan.

Now this is where the governor comes, anything with motor actuality increases or decreases speed depending on the speed of current passing through it which is voltage. The governor increases voltage to the fan when the temperature rises.

Appreciation to Mr Reed..
Got in touch with him about a 48v8kwh battery he had and i assumed the price on his page without confirming from him. It was after making payment we noticed difference was abt 200k. We spoke and he agreed I'd balance him afterwards once client pays balance. He trusted me and sent the battery down and still readily/happily helped with answers when I got stuck during installation.
Installation has bin completed and balance settled.
Thank you very much sir, I really appreciate you.
It was nice doing business with you

capnies:
F

How.much total so others would not make the same mistake.

I KEEP SAYING THAT WE ARE THE CAUSE OF OUR POVERTY STATE, BECAUSE IF WE ARE HONEST, AND TRUSTWORTHY BUSINEESS WILL MOVE SMOOTHLY AND ALL OF US WILL BENEFIT.

GOD BLESS MRREED
GOD BLESS YOU
GOD BLESS THEY PEOPLE THAT FORMED THIS THREAD
GOD BLESS THE OWNER OF NAIRALAND

Phethar007:
Hi guys...I want to get an inverter for my place and I just want to know who I can talk to better that as a good reputation on the forum...

AyobamiOluwole:
I am not a seller nor an installer, I am mainly here to correct some madness.

In all you do, avoid the 400k guy and some other guy who said he will do the same if he was given the opportunity.

So far so good I’ve come to know about some folks whom many have mentioned to have a good reputation:
• MrReed
• Valto
• Damrey5 (I too like this guy for his tear down videos 🤩) Abi what’s that his name
• Dollarnaira (I don’t know if he sells)
That’s all I can remember for now. I don’t know if Seun has anything to say about inverters though.


Sha apply wisdom in all you do.

Pls @all is 4 piece of 535watt of original jinko panel enough to charge my 8kwh battery quickly and also run my refrigerator during the day?

na you dey overComplicate things trying to follow the crowd

For such requirement that closes by 5pm or thereAbout, the following once again should be a good enough start;

2pcs USEd 350w solar panels = 40,000 * 2 = 80,000 naira
USEd 24v 3.5kva or 3kva (sachet or hybrid or standard) inverter = 130,000 naira
USEd charge controller (only when not using hybrid inverter)= 60,000 naira
PV cable (poor man's own) = 20,000 naira
Brand new lithium based battery or USEd leadAcid battery 24v = 300,000 naira

installation costs = As the spirit leads

going 12v would only save you few pennies now BUT cost you more later

if you could afford 4pcs of solar panels, better.

if e still expensive for your sister, check to be sure you not trying to help her while helping yourself.

bassdow:
YES but if you can afford to add extra 2 to make it 6, better.
