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

[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

Okay

Dam5reey:
Hybrid: with Charger and MPPT built in.
Pros
Cost saving
Easy installation
Aesthetics
Efficiency

Cons
Not modular

Non Hybrid : with Charger no controller
Pros
easy to maintain.
independent devices

Cons
High cost
not efficient

On what grounds are they not efficient?

Idle current?

For the cost it's almost the same thing.

Check out any Federal science and technical college (FSTC ) they are about 18 in the country.

Though FSTC Yaba is the most equipped of them all (they spoilt the college with politics and introduction of science education) (qualifications here is nabteb)
A lot of people going to this school now are very young people , when I mean young, small children compared to what we had back in the days.

Check also federal college of education (technical)Akoka yaba (NCE).

Goodluck in your quest

Please refer me to who sell access control materials/devices at Alaba.

Those asking how to solder on 18650s

Another alternative is to tap your soldering iron bit on the battery with the soldering lead.
This way, too much heat is not deposited on the battery

Queed:
The idea is for it to be able to fit into sizeable laptop bag. Next version will be smaller and same specks.

This stuff can't fit a laptop bag.
It will probably fit it without the laptop 😀

goran3310:
How realistic is that? In conditions of inflation, banks often fail. What will happen to your deposit then?

Your regular bank is different from an investment bank or asset management.
Some examples of this investment banks are cowry asset manager ,Stanbic IBTC Capital etc them plenty.

To answer your questions, in case of inflation, if the inflation rate is higher than your interest (the return) nothing you can do your money is devalued.

By the way there are other was to curb inflation via commodities etc

durentboi:
thanks for ur response. Please how do I save my funds in dollars

There are lot of apk and outlet that allows you save in usd.

Mind you the idea of the saving in usd is to avoid depreciation. So you can save in naira as well, but you have to ensure your naira savings or investment is able to yield 30%+( a yield over the present inflation rate).

dollarnaira:
Make una come up with options ooo.
Which one be kerosene gas. Is kerosene still in existence? No vex o. E don tey.
Update me biko

Yes it's in existence.
Just that the demand is low.

For the kerosene gas cooker, it existed at the early stage before cooking Gas became very popular.

bassdow:
Exactly reason why until Now, I still use a mixture of Kerosene stove, and Electric stove. People have advised me tire. I kept telling then soon, Cooking gas prices would rise. I was right after all; as usual.

Of course if anyOne had loaned me a Gas cylinder, I would have used GAS but wasn't willing to invest in something I knew I would drop sooner or later.

Looking to build an Oil stove which would make use of different types of oil. Just don't have time yet.

Wonder why You guys ain't using CNG for cooking yet ?

My own is, I fear for cars using CNG, as in, I hope it's adoption doesn't go round fully as Me go dey select Cars wey I go enter. Make dem no use person do Dynamite

Have you considered using a kerosene gas cooker?

@Obnoxious2001 Good morning Boss
Please can you help me with the inverter Technician phone contact in Asaba to fix my 10kva Felicity Inverter. My contact is oh8oh68396438. Thanks

No vex boss it skipped my mind.

On it

dollarnaira:
The problem with this group, is problem of generalisation. One issue with one technician equal to issues with all other technicians.

Aside from that, if you find a good repair technician, you will say it's too expensive, meanwhile people are more confident sending their appliances to the manufacturer.

There are good repair centre for your mobile phones just make sure you dey wear jeans trousers

bobmalu83:
Location: Asaba, Delta State
Model: FL-IVMP10048
Fault: 1st one input pot not working and the 2nd one the pv line is not working. One of them is sparking inside once it is On on load.

Since you are in Asaba I can refer you to someone who does repair there in Asaba.


However if the inverter is still on warranty, then service center is your option. However you go need get person whey go do the stress of going there/following up the process for you.

So choose from the 2 options

bobmalu83:
Good Day my Professionals in the House

Please i am looking for who or where to fix my 10kva 48V felicity hybrid inverter system. If you have a good technician or their company that can fix it for me i will so much appreciate it. You can drop the contact for me here so that i will reach the person. Thanks in Anticipation

Add location, model and if possible the fault

VanuatuWycombe:
More than that, baba.

I know I just wanted to understand your background

VanuatuWycombe:
- buy better wood moisture meter to check wood moisture before using such wood. Wood with moisture content of above 12% is not too good for use, although people manage 15% moisture in wood.
- Acclimatize the wood in the environment where the final material would be used.
- invest in planers like Dewalt 735 (helix’s/helica blades), Delta, Laguna etc. they are plenty.
- use balls (small rubber objects) in your woods to guide against temperature change that can cause your materials to bend or sag or fold. It also prevents rattling.

Seem you are a wood machinist?

officialfestus:
for balancer?

Yes

officialfestus:
what price?

5.5k

dollarnaira:
Be satisfied with the 15.93v i.e almost 4v per cell. No major capacity from above 4v. In fact you get more life below 4v. I don't go beyond 12.3v for 3s i.e 4.1v.

You are hitting both extremes i e max full charge and lowest discharge. Lifespan will decrease for sure.

Noted boss

How do balancers work
@officialfestus the price is not motivating me enough....

I am thinking of something cheaper .

Besides, I have been experimenting the 4s vs 3s topology and so far I can ascertain that suoer satchet inverter has a high voltage protection of 15.93v which (so any voltage above the reference Voltage highlighted above,will set the inverter into protection mode).

I am currently trying to see if there is a way I can tweak the inverter circuit to get it upto 16v.

If you have any info on this abeg I need am

olatade:
Please i need your expert opinions on this question I'm about to ask

My 60amp felicity mppt CC rating for 12 volts is 800watts, but can one install 2 units of 430 watts,making it 860 watts of solar panels for it?

Will it damage the charge controller in anyway?


It's a felicity 60amp CC

No it won't.
Just don't exceed the maximum PV voltage of the controller

Make a patent of your original design then share it( by selling it to people) this way, even if you die, you made some money from your efforts/design.

Even offer to help them set it up on a contract bases

However remember, you will not only be the one on the wanted list

bassdow:
if at end of the day, you are unAble to get such Fan, or it's out of your budget, just know that you could use a GoTv charger, or any 12-volts charger for that matter to power your rechargeAble fan and boom; e don turn AC Fan.

A lot of those rechargeAble Fans already would work as AC since they mostly have transformer or some sort of way to step-down power used in reCharging the Fan's battery.

This Na direct field experience OT.
