no i did everything exactly by the book. The component was in-between the fan and the board, the inverter didn't turn on at all.

Did the inverter turn on after disconnecting the fan?

If the inveter did not turn on
Meet Olet for his beautiful idea that also work.
That is if your fan stops and work with temp sensor.

dollarnaira:

no, it did not turn on. And it didn't turn on while connected through the speed governor.

It only turn on when I returned everything back the way it was before by joining the wires I cut and connecting the fans directly

Your component is the issue bc I see no reason why it should not work as the device was just to reduce the voltage of the fan. Mine was reduced from 20.6v to around 9v --- a simple buck converter is enough bc voltage will pass through. As it stands now, I doubt if any current flows through. And hope you made use of the 2 main wire from the fan and not the one with sensor?

Guys, what are the odds of a roof leak after solar panels installation and has anyone here experienced that?

earlier suggested he use 1 or 2 (zener) diodes or even a cheap resistor (either of which could easily be harvested off a faulty phone charger or any faulty electronics) if buck converter is far away BUT He choose to go the long route. Sometimes to spend money dey hungry us

it happens when it happens. Mostly when done by someone ill experienced or a mistake was made as even experts can make mistakes.

fuckboys:
yes i know. I need guidance now. The replacement fans can't handle this job.

I've coupled everything back with the old fan pending new ideas.

Earlier on I tried drawing your attention to it.

Besides, look your inverter board well, you see how difficult it is to even see the parts no, talkless of fixing .

Years from now alot of folks will be replacing their inverters.
Hopefully, it doesn't get as bad as I think it would be

Obnoxious2001:
.

what do you think is the way forward?

fuckboys:

By an original brushless fan.

If you decide to tweek it, we will need to introduce a new microcontroller, that's going to interpret the PWM signal from the main inverter

When coupled with the old fan does it resume working as usual?

Never mind I just saw your answer to someone.
One thing I can say is this, even brushless fans make a bit of noise too, if your space is kind of enclosed then you cant totally do away with fan noise

OK Thanks.

The idea doesn't sit well with my Landlord and honestly, I won't want to start battling a leaky roof afterwards. Really skeptical.

With this sachet inverter with battery charger, will thr inverter still bypass when there's grid input?

Iinnov8:
They are actually Lithium batteries (LiFePO4) made with Grade A cells. See datasheet attached. A capacity test has been done on them, see links below, and we will be conducting a live strip down test on them soon.

And yes, it can power your house. You either get an inverter, AC charger and solar charge controller (as seen in first picture below), all of which i can provide, or get an Hybrid (all-in-one) inverter. I have a Haisic 1.5kva available for 190k. See picture below

I gave an idea on this earlier, you don't need to replace the fans either. You can quote me on a dead thread with your Whatsapp for guidance

Please can you share the guidance, i also need solution to this.

You appear to be closer to @Valto hence could easily buy things from him including pureSineWave sachet inverter for about 70,000 naira

Solar Panels: A single USEd 400w mono (optionally halfCut) or 2pcs of USEd 350w mono solar panels.

Battery: Lithium or LeadAcid . If buying leadAcid, go for USEd 12v 200AH else go for brand new Lithium battery.

Charge Controller: Budget between 40,000 naira to 80,000 naira for a quality used MPPT charge controller. Go for minimum of 60Amps for future purposes

PV cable: Just use the NEPA wire. That ash colored cable that draws light from NEPA pole directly into your compound. SHould cost around 20,000 naira or more if you go for quality. For your size and budget, Copper is not worth.

installation: come and disturb us more OR stress the person who sold things to you with lots of questions + directions. make dem sef follow work.

I no go tell you to upGrade your Tv but with time, na your tongue go by himSef count ya teeth.

Don't forget, Oga Valto dey delta state.

Kindly help me with a what I'd need for my solar set up, I have a 45inches TV, 32inch TV and a 42inches TV, 4 standing fans(not OX) 15 light bulbs, 1 deep freezer. A story building house as to how much cable would be needed. Thanks in advance sir

see eh, Just assure your landLord that the roof would not have issues. then get someone experienced enough to handle the job and that's it.

Doesn't matter the roof type Gerrad, slate, zinc, aluminium, etc.

That shouldn't be reason you not enjoying Solar life except there are things you not letting us in on.

To be on extra safe side, tell the installer to go along with flashBand should in case there's anywhere that might get a little dent no matter how small.

@Olumighty123 , a single quote is more than enough. No need SPAMing the entire thread

You didn't state if you stay at ground floor or upStairs.

how many litres is your freezer ? is it the old school type or the energy saving type or inverter models ?

The Televisions, are they flatscreen or the old school box type ?

if you are on the ground floor (downStairs), you would need approximately 25m of PV cable BUT if upStairs, then half should do.

You also didn't state your budget. If you had checked past comments, should have picked up one or 2 things from them. Myself learnt by reading and practicalizing. I no carry knowledge come this world.

yes it did start working at normal, the inverter came on immediately.

have suggested He takes it elsewhere so it doesn't disturb his peace.

if he hapens to stay upStairs, balcony is good enough or put am for passage BUT if na self that is contained, well...

alternatively, leave the system open so enough breezer gets into it; AND if it wouldn't start without the FAN, just trick it into thinking there's a Fan.
or just use (Zener) diode or small resistor to drop the voltage enough that the system continues to see the FAN but it's slow enough your PEACE remains intact.

No need allowing something simple and basic turn complex

JoeSef0:

Good question.

No, it doesn't do so as a follow-come feature. It is a budget setup afterall. But it can be made possible using a relay switch to automatically transfer your load to grid, if available.

However, if the charger is connected to a separate socket that is NOT powered by the inverter, but pulled out from the point grid or gen enters your house so that the socket/charger only comes on when there is nepa or gen light, then you can have a system that runs without your intervention to a great extent.

Your battery will immediately begin charging as soon as there is grid input, even though the inverter is on and still powering your loads. And as long as your loads doesnt exceed the amps rating of the charger, the batter will be getting charged while your loads are still being powered. You can then manually switch to nepa light at your convenience.

Not good enough

Soldering 18650s isn't even the best approach. He should invest in an inexpensive spot welder. The rechargeable one I got 4 years ago for 25k is still going strong.

He should use nickel strips or even copper strips for goodness sake.

Is there a BMS in this thing 😳? Cos that pack is a fire hazard waiting to happen. 18650s aren't so forgiving with irregular charging and thermal runways unlike their counterpart in the phosphate chemistry.

Marykhay:
Seun stop banning me na

😫

Abeg dollarnaira, Valto, Mrreed and other builders, please what configuration is this? I just opened the system.

This is supposed to be 4S2P for 768Wh system.

dollarnaira:
Exactly!
Why you dey hit points this morning bros.

My full copper Belgium Ethernet cable is just there looking for more pv to be added. Shey bi na here all us gather dey.

If you don't have sense don't use Inverter

Hmmm. You adapted ethernet cable as your PV solar cable?

Toh.

Marykhay:
Good morning Chiefs,

I’m having a head start with my issue.

With regards to this system I posted earlier, these are the readings I got from the 4S configuration using the BMS connection the builder did:

Battery 0 -> Battery 1 = 3.18V

Battery 1 -> Battery 2 = 3.18V

Battery 2 -> Battery 3= 3.18V

Battery 3 -> Battery 4 = 3.2V

The problem, like I mentioned earlier, was that the 768Wh 12.8V capacity does not even get to half of what it should be. I guess this result is giving me a conclusion already.

But I need to hear from experienced builders:
@dollarnaira
@Mrreed (you no even dey reason my matter 😭)
@Valto (Senior man, at least say anything)
@capnies

Please what do you think is wrong with this system?
A. Weak or refurbished cells?
B. Unbalanced cells (I don’t know if the imbalance in the reading is negligible) causing the system to not reach its complete capacity?

This may come in handy, not as a pack for your inverter cos the UPS rating doesn't support that high inverter current draw. But it can function well as a backup for your router & DC fan. Charges on 12v DC supply. Typically 3s2p 18650 config, but you can parallel each cell for extended capacity in which case the case/slip-on cover will become redundant.

Been using mine for 3 years as a back up for router & 5v tuya hub.
