you know where I can source that from?

It has yellow, blue, red and black wires. 12v

Try take a clear pix:
Terminal
Spec

But wait o
You recently upgraded to 24v right?
Where is 12v coming from?

Good morning sirs
I am experiencing a problem with my Felicity IVEM4850 inverter and need assistance (I am based in Ago-Iwoye). My setup includes 8S2P PV panels (Voc ≈ 44 V per panel). The inverter was working perfectly, with a PV input of around 251 V and supplying power to my loads. This morning, when I switched off the main utility (grid), I noticed that the PV display on the inverter immediately went off, even though the PV panels were still connected and producing power. At the same time, my freezer turned off, while a bulb light connected to the inverter remained on.
The inverter continued operating for about five minutes before it shut down completely. When I tried switching it on again, it immediately displayed a red warning light, emitted an alarm, and showed Error 29 on the screen.
Weeks ago, I had also noticed that in the morning, the inverter sometimes displayed PV voltage even when PV was disconnected, which I now believe may have been an early warning of a developing fault.

the fan itself is a 12v dc source .

I will take a picture when I get home

I'm thinking of ordering brushless fans from aliexpress to swap out the current ones in there.

But the fans in the inverter has 4wires while the ones I'm seeing are 2 wires.

Better u get it around as used.

4850 abi 5048
IVEM5048 voc is 280v max

Are you sure the Voc is 44v? Jinko 670w Vmp is roughly 43, Voc is 51v. So confirm the wattage and brand.

its is IVEM 5048, and the voc is 450 V (the solar panels are 275 W, and the VOC is between 44.3 and 44.4 V).

Ok but
This 5048 is 90 to 280Vac

Baba if you restart the system and it acts the same way, just take your inverter to Felicity Repair center.

That is AC input voltage range, not DC

Thank you, sir. The issue is not based in Lagos.

Yes
Dc

Omo this inverter noise wan kill me, newly improved haisic inverter my ass. I no dey fit sleep well for night again.

Between the haisic and bread which one of them makes more noise?

Abeg all these inverters na from the same factory from china, same internal components different brand packaging.

Both Haisic and bread always have their fans running 24/7 and loud also.

My Haisic is mostly quiet unless on high load..

It's even still relatively quiet when using submersible pump 1.5hp

U only notice the noise from usage of microwave and high loads of which the noise comes back down after u turn it off.

Another instance where I face loud fan noise is when charging at high current... Say 50 amps and above. The higher u go, the louder it is.

Mine is super ventilated o, I guess that plays a major role.. Like it receives enough amount of cool air from a large window close by.

Friends I need 24v 50ah lifepo4 batter

Guess it's that model that comes in white and black/grayish varients. na so small thing, dem Fan go dey blow like Fat orobo wey pursue pregnant goat.

But that sound isn't often steady. It comes then goes down BUT it can be loud enough to become a disturbance especially if installed close to sleeping area.

When you try to discourage some clients BUT they think they know better. Me ma no kukuma sabi go for just aesthetics. in fact that's often last on my list.

don't just compare brands, compare across same capacity also

Spoke with someone who imports (i mean the actual importers) things abroad and He said a lot of brand new solar panels are mass produced from China and in China, they don't have factories everywhere. they just concentrate factories within a particular region unlike other countries where you could have Solar panel factory in Oshodi, Ajah, Surulere, Sango, etc; According to him, if you see a solar panel factory in Oshodi, all other similar factories would all be situated in same Oshodi even if all they do is manufacture things required in manufacturing Solar panels.

Then I thought of it, not everyOne buys Tokunbo TeleVision due to lack of money for brand new, some do because it's got better quality than brand new ones readily available.

Also notice a lot of used solar panels today have prices close to that of brand new ones.

why not enter Oshodi or Alaba ? or send person message if you got no time

shoul you take your time on it, you would understand why it's 4 wires and not 2 and how to probably get around it.

na why I love science and engineering; no room to disturb God / god, you're forced to think for yourself one way or the other. No God/god help me do...

HawkTuahGirl:
I m not an installer, I m a user. But I install the system myself, almost the same system. One jinko 550w is enough but raining season will humble you.

I will suggest in addition:

A single 715 panel instead.
If you have small Nepa light, buy 20A Battery Charger o.
You get generator, keep am, no sell am. One day, sun and nepa will fail you and business must go on.
And that 100A cworth battery no worth am, go for 145A or 150A

Walai I feel you talk from experience

Me I know say I go buy gen support am.
What type of inverter are you using?

I am using 3k pure sine. The very one suggested here.

Ohh i see. Na to change the fan be that, i will do same to my own.

I guess yours is different from the one fuckboys use

Baba don't tink twice go for Lithium lifepo4 it is the best but make sure u do a proper research on the brand make you nor go buy lithium battery wen nor complete watin they write for paper

Mykcool:
Please more review on the highlighted, I plan on changing mine by months end.

How many phones do you project to charge at a time? Because a 12v system is not suitable for commercial phone charging, best you increase your budget and go for 24v. I am talking from experience as I have to upgrade a customer's system from 3000w 24v satchet inverter to 4.2kw 24v hybrid system with 4pcs 455w solar panels as the satchet inverter cannot cope with the numerous load of power banks and phones brought in for charging

Projecting 20 ( phones and powerbank) min.
150a cworth, 3k inverter. Ive decided to slow down and get it right. For now, the panel will be 1 pcs of 550w jinko. Younger don dey lok as the weapon fashion against her. With the way I dey call monies.
