Honest question though, Why the client preference for tubular instead of lithium?

Second hand value obviously

walexsos:
Pls is there anyone here who has installed a welion 6.2kw with any lithium battery before, i am having serious challenge establishing the connection between it and my firman 10.2 kw lithium battery.....it has a bms port but whenever i connecting the bms cable that comes with the inverter, it doesnt activate

.
Use user defined

nnadychuks:
pls what’s MCU

Micro controller unit

odimbannamdi:
Please does any one have this for sale? Either new or used. Also something similar, I am fine with it. I am not very sure of the quality of the ones on Jumia, plus I am on a budget and need it urgently

Go to arena.

Ask for ik component.

It's available there sells for 60k

nnadychuks:
System voltage is 00.00V but voltage on charge controller is 12.8V
I believe the inverter isn’t displaying the battery voltage, or current isn’t passing through

The MCU is probably bad or the battery sense init

nnadychuks:
Pls help
I’m tired.
It seems solar isn’t for me o…
Can someone tell me why my inverter won’t generate current?
The inverter shows battery 00.00V, while charge controller shows 12.8V

This is just few weeks after buying a new mopower inverter

What is the system Voltage?

Does the inverter invert

micxwell:
No. The specific field you studied in school; at least your reports will be based on what you studied in school.

Your Degree certificate is one of the requirements for registration and the field you're registering in should align with that certificate.

They won't register you as a Mechanical Engineer if you have over 4years experience in the field; when your Degree is in Chemical Engineering for instance; you get the drift.

Yes

micxwell:
Go and gather experience. 4years after your service year, then you can register.

The experience, can it be in any field of engineering?

Thank you

officialfestus:
yes it does.

Okay thanks

officialfestus:
It seems no one is building at the moment, I'm just waiting for my goods to arrive from aliexpress.

I am building a student power bank.
Am considering running 12v or just 3.7 with power bank module...

So I need pratical experience on this
Does the BMS below cut off the battery once it is low?


The person requested for a 50000mah Mobile phone charger anyway

[quote author=omonla5 post=131048722][/quote]Thank you chief

Please who has Ipower inverter manual.

I am trying to decode the meaning of F2 and F3 error code

Please how do I enroll/register for Coren.

I just graduated University

Bokajimike:
Hello Nairaland,

I am seeking advice on relocating to either Germany or Canada at the beginning of next year. I currently work remotely as the sole UI/UX designer for a tech company in Nigeria. I am married and in my late 20s. The idea of relocating has been on my mind for a few months now, and I have seriously been considering leaving the country. I hold a degree in Electrical Engineering.

A friend suggested that I could move through a study program, but I am not sure if I can focus on academics at the moment. I am keen to hear how others have successfully and legitimately relocated. My wife is insistent that I shouldn’t leave the country without her, so I am planning for both of us to move together.

I would appreciate any advice on how to proceed with relocating to either Germany or Canada. If you prefer to share detailed information privately, my email is in my signature.

Thank you in advance for your help.

olaztek:
It's easy to set operating current of a buck converter if the load is resistive / inductive such as a led bulb or motor, but for a battery, it's quite tricky.

The constant current provided by the buck changes in tandem with the battery voltage level. If the battery is low let's say at 10.5v, the buck will deliver a high constant current. As the battery is nearing full charge @ around 12v, the buck delivers a low constant current.

For simplicity sake, just tweak the current trimmer clockwise to the max level till you start hearing some clicks from the trimmer, set your charging voltage, and put a cooling fan above your buck converter to prevent damage from overheating.

Doing this will not make your buck converter to burn out irrespective of the solar power rating supplied to it.

Bulk doesn't have the ability to regulate its preset voltage with respect to battery voltage when using it as a charger.

It's Solar charge controller that does that

kristien4:
Na,so i tell wan yeye installer to go install 8panels(450w) each,5kva,batteries. told him it was upstairs, benin city. He charged 70k. He went to the house, saw swimming pool, saw bushbar, saw duplex/luxury. He call me say boss that client na bigman, i no fit do am for 70k again, na 150k i go collect. I ignored him, got another installer to do it for 60k. Job is a couple of months old now, no wahala no complain. Like i said, na u get ur price, u fit call 2million to install 8 panels. Appendix operation na 70k for general hospital, same operation na 400k for private. Coke na 250naira for street, for club na 3000naira.Life na choice.

Good day house....
It's been a bad thing for me....
I can't communicate freely with people.....

Like sometimes I don't know what to say...or I can just go off or start stuttering....
I need help in this area.....To be able to be jovial lively and associate able....
Please anyone who's overcome this social disorder and communication anxiety should please help provide solutions....

Thanks

A simple technique is to keep it short and ask open ended questions if you wish to contact the conversation.

Sense of humour is another thing

swagifted:
Whats the worst that can go wrong in buying a fairly used inverter.... I mean is there anyway to check the mileage?

Inverter no be motor .
You will have to rely on what the seller is telling you

Ogarexmas:
Who has used this and how long does it last. I want to use it to power just my Hisense 43inch smart tv. And does it need much installation since I know nothing about it.

I don't think this is the current price.

Besides the system is for very light load

AdexAyanfe:
Thanks boss. The buck converter module works so well. I went for a buck converter above 5a. I will consider a better pmw or even mppt when I'm upgrading to a bigger set-up. Thanks boss. I appreciate everyone.

Do you discharge from your BMS or directly from your battery?

I have this set of batteries I assembled and I have been wondering which is best

4th May,2024

After so many I dey road dey come from SNR man.

We ended up mounting the 9pcs of 580w panels on the roof.
Just I and emeritus D great .

Low-key I was looking for who would assist us considering I was on the roof (asbestos) and emeritus on the ground. But it seem emeritus has finally put his weight lifting to good use .

2nd May,2024

Location: Apala

4640wp solar panels installed.
7kwh battery
3.5kva felicity hybrid inverter


Earlier on the 1st of May, I visited this site to survey it before heading to leventies. We completed the job over there and commenced the job on this current location.

On this day we prepared the protection system (the earth pit) @brightk brought in a colleague from PHCN that supervised the whole procedure and Standard.
(Modified: we made use of gem, although the PHCN guy was not in agreement with us, he like money whey I fit use chop , then he shared an alternative they used, cow dung and dongoyaro leaves. Surprise? So I was)

After the whole preparations, it started raining and we called it a day.

We just dash the ladder owner free money .

Obnoxious2001:
I got in with my journeyman and we started preparing the mounting rack ( we used interlock aluminium profile for this job, from experience I think they have better stability when trying to nail them into the roof)

We did some calculations to manage material my oga you dey owe me . So we ended up using 3pcs of aluminium profile to mount 8pcs of the 550w solar panel.

Preparing the railing was not the problem self, pulling the panels up the roof was too stress full (all my body done break forget I said I was made for this 😭😭).

There where some many challenges with the ridge board has broken and some of the wood.

So we had to swap position (who dem dey lead sometimes no know Wetin leader they see) with me myself taking the most risky position on the roof.
We dont have pictures of the process just minor clips here and there.

But am grateful, am able to come back to this thread to document it
.
Shout out to all the key people involved in the project.

Hopefully, we I will be sharing update on battery and inverter system.
We are having some down time procuring the batteries

May 1st 2024.

Who remembers this 2 storey we worked on earlier?
We went back to that same location, but this time around we are to remove the solar panels and re-install them.

Initially the scope of the job was to bring it down totally then raise it back up.
I was like that is a lot of risk I will be exposing my team to(as we dey find money we still dey pray to see the next day Hale and hearty).

We discussed with the carpenter and came to a compromise that we will move the items around then roof simultaneously as they worked.

28th April 2024.

A colleague of mine reached out to me that there was a government project that needed to be executed before on Monday.

Been familiar with government projects timing, I wasn't expecting it to be as soon as possible(i was informed on Thursday).

On Saturday the 27th, 8 able and capable bodied men headed out to Benin to commence the project.

We arrived Benin bypass at around 12pm, then boarded another bus to our apartment (yes there was provision for accommodation, but it was very far from the location that we had just spent a night then ditched it).

We used the opportunity to get all the railing, nails and bolts for the installation

On Sunday, the job commenced .
The weather was not friendly at all as we worked under the harsh weather conditions ( we were trying to meet up with the commissioning date which was Monday 29th 2024)

We worked day and night, because we were to mount 48pcs of solar 420w solar panels(10kwp of PV per location), 2pcs 15kwh felicity lithium battery and 4pcs of 7.5kva inverter at 2 different people location.

I have attached some images of the day and night life of the job.

One good thing this job did was expose me to other ways of mounting bigger wattage of panels, because brainstorming and coming to agreement took a whole lot of time but it was worth every part of it.

24th April 2024.
Location: Alegbo

Small set up for a moderate load.

The client wanted a fridge running on it just in the afternoon( I have included the name plate of the fridge)
The fridge is supposed to run 5hrs daily
We finally ended up going or a 1.5kva inverter 12v, 1pcs tubular battery and 3pcs 300w solar panel.

25th April 2024
Location: DSC steel town

1080wp of PV (6 unit of 180w though the client claimed they are 250w )

As usual we headed out myself and emeritus D great.

Before then I had supplied the almighty 60A powmr mppt solar charge, (I still have a unit available in warri if you need it).

The client procured his solar panels, wire then he reached us out again for the installation.

As usually we delivered.

Before we started, we had doubt that the space available on the roof will be sufficient, after so many back and forth, we delivered it as usual
