okay, I guess it's normal.

Yes definitely

fuckboys:
morning Chief, please why's my charge controller reading the battery voltage different from the inverter reading of the same battery ?

Multimeter reading of battery at the terminals of battery also different from both the inverter and charge controller, please any explanation for this?

They all different by 2 units, multimeter would measure 13.6 while inverter 13.4 and charge controller 13.2.

Different degree of precision and tolerance

🤣🤣🤣

Installer destroy am ke? Wonders shall never

Exactly, you will see how unprofessional the installer is all all that but this things are bound to happen

twosquare:


If I had known, I may not have gone for it, but the deed is already done. Looks can be deceiving. I think these guys should work more on weight and portability, as some are already doing in the industry.

If owner dey express him concerns like this,
Imagine say Na the installer destroy am .

dollarnaira:
There is no way 200+ will be charged at the same time. Did the customers planned their meeting point at the same time? ;DPhones get fully charged at different hours.

I know.
But then the guy said 200+ devices

Alexta01:
Wow thanks. Let me check it out. Any counter measure against solar theft?

200+ phones is around 4000w oh.

Since you are using for business, you might end up spending up to 5m if you want to run it efficiently.

I will advise if possible maintain your gen(consider using biogas) and use solar if load is within a predetermined range.

RealSean:
ahh nawa so how much go fit over all these listed items boss? Yeah one ox fan and normal fan

You are looking at 4.5m up

RealSean:
ok thank you sir. The items I would love to cover are atleast a 42 inch TV, a mini fridge, an inverter 1.5hp ac, 2 fans, a PS4, a few bulb lights and dstv. It's pretty much all the items I use that requires electricity. Thanks in anticipation

Your load Na Wetin big man dey use .
That 1m budget, can only manage to provide power for the tv, light, DStv and fan (I want to assume the fan is not ox because wahala go dey)

How Can Nigeria’s Banks And Politicians Work Together To Promote Solar Power For Everyone?

Hi everyone,

Solar energy has the potential to transform Nigeria’s energy landscape, especially with our erratic power supply and high generator operational costs of petrol and diesel. However, adoption is still slow. I believe the government, banks, and solar companies need to collaborate more effectively.

For example, the government can provide tax breaks for solar projects, while banks can create low-interest solar loan schemes for individuals and businesses. With better political will and financial support, solar power can become affordable for most Nigerians.

What do you think? What role should politicians, banks, or private companies play in making solar energy widespread in Nigeria? Let’s discuss!

I think there is a tax wavier on solar panels already, what we need is more investments (although some companies has started providing loans for financing solar project, how the interest rates are not encouraging)


I think government should focus more on combating importation of finished solar products (this way, a lot of jobs are created, while monitoring the standard of products that goes into the market)

RealSean:
Good morning house. Due to the situation of the country and how electricity seems to be declining as the day goes by. I was thinking of opting for solar energy, I would like to know what's the best package 1 million naira can possibly get. Like a total breakdown would be much appreciated. Thanks in anticipation

Drop a Break down your load..
Irrespective of your load, the cheapest package you can go for will cost you between 750-850k.

The package will include
a mppt controller, 100A lithium battery, a unit of solar (440w) ,wires installation etc.
It will include

Inverter Cable available for Sale, call or WHATSAPP 08035537864 if you need it

Dash us the cable

Please add me to the group.
Am trying to get certification in marine engineering I don't just know where to start from

I think it's more advantageous to use 4s than 3s.
Easy compatibility with charge controller

omotoda:
You have exceeded the Max VOC rating for a 24v set up for PowMr.The max VOC is 105v.You can't go beyond 2units of 280w in series for a 24v set up.You are lucky your CC hasn't fried. What brands are your panels? I am sure they are not up to the rated capacity that's why your CC hasn't burnt!

It wasn't exceeded check the PV voltage

smitashah227:
Hello everyone,

I'm currently considering Jakson solar modules for a solar energy project and came across their product offerings on their website. I'm particularly interested in learning more about the key features and performance metrics of their solar panels.

Can anyone share their experience with Jakson's solar modules in terms of efficiency and durability?
What makes Jakson’s modules stand out compared to other brands available in the market?
Are there any specific maintenance requirements for these panels?
How do Jakson's products perform in varying weather conditions, especially in areas with extreme temperatures?

But let's check it out

imatejammer:
I got this quote for an inverter set up to power 3 Panasonic ceiling fans and 6 energy bulbs for 6 straight hours: (No solar panels)

SMARTEN 1.5KVA INVERTER---------------------------200k
STARPLUS (TUBULAR) BATT 12V/200AH-----------260K
CHANGE OVER BREAKER------------------------------------8K
RACK -----------------------------------20K
LINE MONITOR ----------------------------------12K
INSTALLATION FEE ----------------------------------35K
T O T A L--------------------------------------------------------535K

Is this a fair quotation?
What if I want lithium battery IN THE MIX? what size and price?

I think this is fair enough.

Ray1251:
Please quick question: My solar panel (Jinko 555W Monofacial Solar Panel) has a Short Circuit Current (Isc) of 14.07A, panel's maximum fuse rating (30A), which would be connected in series. The Required breaker size would be 14.07A × 1.25 = 17.59A, meaning I would need a breaker with 20A, right?(connection from the panels to the breaker then inverter). I wanted to confirm if this calculation is correct ? installer said we would need 65a for the setup ?

What are his reasons?

bassdow:
You see that 300 watts panles eh, they are not just heavy BUT wide, and to carry am climb ladder, especially for any building more than 2-storey, na better work.

What I often do is use rope to pull it up because if e fall or hit something well enough, you don buy market BUT it never occurred to me it could stay on it's own without support.

Naim easy pass to install.

I personally feel onces the installation area I very high, smaller wattage should be used

Following this roof discussion, but let me digress no be for This thread them say installer workmanship was too expensive

Bb007:
Any idea of the cost, durability and if there is any particular brand to look out for when buying a solar water pump?

They are durable
Cost should be around 800-900k
For brands I cannot say much about it, but I mostly install Myhome

Bb007:
Please is anyone here using a solar water pump or have installed one. I am looking at installing one in an area with no light to pump water, but i can't find much information online.

Compared to setting up a small inverter system to pump the water, which will be cheaper if one is working on a budget?

What information do you seek?

Both options has its advantages

HanisahZuwy:
Please what are those happening places? I really want to be able to earn something so that I can take care of some basic needs and other things. I've tried sites for some days because I have experience in iron works, but... it was hectic, maybe because I'm not used to it. I'm into industrial cleaning, but getting houses is another thing altogether.

By iron works , you mean say you be iron bender?

No vex

tetralogyfallot:
I already have for battery packs but I'll consider for the small small consumables too sha

Your bank's where is your Lagos pick up incase one wants to buy?

frebor:
Good day DIYers, anybody have an idea where I could get a replacement? It comes from a old modified wave Mercury inverter

The MCU.....
It's hard to find but in case you find it please update us

Who has 20A buck converter for sale
Location lagos

[quote author=tetralogyfallot post=132722130][/quote]You sell that round brown insulation paper that stays at the positive terminal

mank1234:
HF inverter can be replaced in few hours for those in the city. And probably within 3 days for those in hinterland.
Who needs sachet inverter to remedy any situation?

With the way battery is improving, very soon all-in-one system, HF HV with built in battery will be the order of the day.

If you wear jeans trousers and can drop Benjamins, without grumbling definitely 1-3days will work.

If you wear Ankara with fila, satchet inverter is a very viable option.

Hi everyone,

Interest over the years has grown to see what the vocational side of our educational system can offer. Conversation with some home builders (sole proprietor) is indicating low turn out of reliable tradesmen or women to handle task.

The idea at this point is to seek out government owned or Private (Government approved) Technical /vocational schools that teach Masonry and other aspect of home building to prepare the student for employment.

The next step will be to evaluate how to make reasonable offer to the graduates or senior students (No room for child labour) for seasonal independent contractor jobs on a small scale with room for expansion and renegotiation as the project expand.

Reaching out to get pointers about technical schools where one can get masons/ home builders to employ. Either Government owned or Private (Government approved). The goal is to work with the Schools to have a pipeline of technical school to construction site jobs. This is pretty much at an infant stage. Suggestions will be greatly appreciated.


Thanks to @obnoxxious2001 and @SKydivine that have offered suggestions. I look forward to hear from everyine and make this thread a source of information for those seeking this info.

Most of this school has courses they offer:
There are government technical colleges (GTC) (most are not properly managed now), Federal science and technical college (FSTC) and college of education technical (C.O.E.T).

Considering that you tend to teach the employ, I can tell you first hand that the syllabus is first hand(I still have my notes from technical school even though I have change path).

What needs to be improved is the practical part of learning. Then probably they can allow the lower class to attend more workshop practice on Saturday.

For the employment (I think internship should be a better approach) offer them when they have finished with stipends so that way those who have graduated before and currently can learn more on the field before the normal employment.

I'm yet to see a Nigerian who thinks that External CCs are waste of Time and Money in the present day Renewable Energy Systems.

Can your charge controller invert DC to AC when your separate Inverter becomes faulty?, Of what use exactly will your Charge controller be at the point in time?

Please answer sincerely. Except of course you want to tell us about how you can still power your DC gadgets. But outside this, please educate us further.

The seperate cc will make sure your batteries are charged, while a backup inverter can do the inverting pending when the main system comes up (satchet inverters can remedy this situation)

Dam5reey1:
Well, If you use Hybrid like Deye, Growatts and co, Failure rates are very low. Dont be carried away with all these Elcheapeax Hybrid flooding the market, also unprotected installation amongst budget installs and abuse.

4 years running Hybrid zero issue...

I have no problem with hf hybrid inverters, but you can not put the transformer based inverter at a disadvantage on the ground of efficiency no Na.

Idle current is not a big problem the way it is portrayed on this thread.

Calling big names inverters, deye and the Geng. This is Nigeria.

If you create a poll here to find out how many deye or whatever has been installed so far this year you will find out they are less than 200. This is because it's mostly enterprises that will/can easily pay for it

But once you call felicity,welion,sms even Sako whey just enter market, you get hear present tire

HeavenlyBang:
Baseless take. Na you wan spoil am? Pretty much every solar setup I've seen abroad uses a hybrid inverter, and not a transformer-based one. How come those inverters aren't dying every day.

Na so dem say carburetor better pass injectors back in the day.

Omo Yankee and Nigeria no be the same.
Just the same way Yankee dey run PV combiner box even for domestic use, for Nigeria here Na ahead ahead .

Besides @jonesco already gave a valid point why they use hybrid more (net metering)


So with this few points of mine I hope I have been able to entertain you while educating the forum.
Thank you and God bless you
Shalom🙌🏾

HeavenlyBang:
Money for Felicity 120A MPPT reach to buy 3.5 KVA hybrid with 80A inbuilt normally.

At this point, there's pretty much no value in buying a standalone inverter.

Is when your hybrid inverters develop faults that you appreciate the stand alone.

Any little fault on hybrid inverter you are look at almost 100k on repair.
Besides you are left completely stranded if you don't have a redundancy plan.
(if you dey this ship go and make plans down storm is coming )

So if you do a comparative cost check, transformer based are cheaper over time

Dam5reey1:
Cable losses, connected device..

Stand alone Inverter is more expensive na. Unless you are not in market.

Cable lose is not a factor of Inverter but rather associated devices / application.

Even the HF inverter require you size the wires adequately.

I will still maintain my stand point, a lot of good product exists in the market, but no body is willing to use their money to test them.

So test brand/names make more money onces they cross the threshold.

Hogwarthtrades:
Thanks for the information, greatly appreciated. At this rate i will open a new thread for follow-up.

I will be following.
Thank you
