Automatic change over

Havesomesense:
I have 500,000 naira for rent, I want to relocate from Lagos, which state can I rent a good flat for with N500,000.

You guys should advice me.

Modified
Which of these states can I get a comfortable flat with 500k and is also good for business.
1. Delta (Asaba)
2. Oyo (Ibadan)
3. Kaduna
4. Abia (Aba)

Delta State is a low budget Lagos State but you see when it comes to housing all I have to say is Omo (you might probably have to stay at the outskirt to get affordable housing)

But that aside I think is a very strategic state and I have been wondering why people/organisation ain't thinking of the state.

justasitis:
Thanks for your input, the Mercury 2.4VA inverter has the Charge Current Regulator at the back- 10A and 20A depending on the battery capacity connected.

Use a lower current to charge it

ajabani4allah:
The charging system is designed for lead acid battery not for li-ion or lifepo4 battery

For inverter that don't have editable settings
Look out for
1. the maximum charge voltage
2. The charging current (this is very important)
If your charge current is too Much, you BMS may then to flicker.

I think this inverter has a charge current regulator 10A and 20A button behind the inverter.

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 .

After we had earlier installed the solar panels, we installed the battery and inverter on this day after @brightk was on malaria 🦟 break.
Battery was gotten from. @valto

May 8th 2024
We commence the installation of the accessories (the heating element) And fixing the housing etc.

The job requires careful maneuver and mind to work at height .
This particular site had a lot of wind and breeze son of Man was very careful

Feed your eyes and ask questions if you have any

May 6th 2024.
On that day, we( emeritus ,I and Solar guy)journeyed from warri to ughelli afesire precisely to install a solar water heater.

We got to the site planned the structure (we used am existing overhead tank, the owner does want anything on the roof) supervised the process.

Structure is set we head back to base to prepare for the installation proper

4months down the line...
Let me update the thread

@ Dam5reey1 @dollarnaira @ Obnoxious2001
What could be the reason PV input is zero on my Felicity 3kva inverter (pv reading 37V testing using multimeter)

Check if you have met the minimum required PV input voltage

KingGeedorah:
Thanks for the feedback

Can l have a situation where l keep the old generator cable but run a cable just for the solar inverter, where the solar inverter only powers lights and selected sockets.

You need an electrician at this point.

preyeamaorutobi:
Thank you sir for your response. I was told I need a 24V inverter to be able to run my fridge that was why I was thinking of upgrading the inverter to 2.5kva. I don't know if I'm in the right track but if getting just a another battery will solve the problem then I will be very happy.

Your inverter is 1.5kva which Is adequate to provided power for the fridge. You just need more current (battery) so you don't damage your existing battery ( i no wan dey explain in details)


Your 60A mppt controller would not function to its maximum abilities since your system is a low voltage system so pwm are better

preyeamaorutobi:
Good afternoon, great people. I found out about this wonderful solar forum just last night, and I took my time to read some comments. I really appreciate everyone here for their time invested in answering questions.

Please, I'm a newbie on this. I just got these solar systems.
Glow Energy 1.5kVA 12V Inverter
Glow Energy 220ah 12V Battery
Felicity Mppt Charge Controller 60ah,
100W Panel 6, and 300W Panel 2.


I got them about two weeks ago, and I found out that it can't power my inverter fridge with these specs.

Rating 220-240v, 50/60Hz Rated current: 1.15A Defrosting input: 220v/230-2240v Rated input of heater cord: 95w Annual energy consumption: 235 kW/year Rated power input: 65w Dimensions: 555 (W) x 585 (D) x 1520 (H) mm

I use the system for my
50-inch smart TV 120W
1 laptop lighting.
Power bank.

I never knew it wouldn't be able to power my fridge; I felt it would because it is an inverter fridge. My mistake was not doing proper research before getting it. So please, what will you advise I do or change to enable it to power the fridge and also a washing machine of 7.5 kg?

Why can't you run your fridge?

You just need an extra battery connected to the system then a pwm controller.

Unless you are having convictions to sell everything off and start afresh (that's if you are planning to run future upgrade)

Don't be surprised if the government introduced Solar tax.

They are collecting it already Na.

Mackin:
Is there anyone who has used City & Guilds of London to register under COREN? What category of membership would COREN offer for Level 5 City & Guilds in Mechanical Engineering?

Speaking of city and guilds, are you certified?

Am looking for where to take the course

bleexInc:
Thanks a lot for the response. I hardly drain the battery. Maybe once or twice a month in the last six month. Where can I get the external charger in Lagos.
The battery was gotten brand new from D2H. It’s a 24V system.

But souer 12v 30A charger. X2
1 for each battery

bleexInc:
What do you mean by external charger

Seperate charger

bleexInc:
Hello House; kindly assist.
I have an inverter setup with 2 Amaron quanta 200AH battery and 1.5kva luminous inverter that I have been using for about 18month now. I use nepa light to charge it.
It use to have backup light of about 6 - 10hours when I started using it. My major load is my 65inches TV and 3fans with bulbs.
Now, the setup get fully charge in less than 2hours and get drained in less than 2hours.
What could be the problem.

Get an external charger.

ajabani4allah:
Bro, that inverter is not strong enough to tolerate leaving it 24/7 on, it will spoil in no time. Get PSW sachet inverter for this

You must have had bad experiences with satchet inverters, those inverters are durable and can run 247. They have the same architecture with PSW just different output stage.( In Psw the outstage has a microcontroller that generates spwm that is linked to the output MOSFET)

ajabani4allah:
That part "put off the inverter" pls can you shed more light on this? I have a 10A 8pin DIY relay I am using but it can only transfer the load but not put off the inverter. Can the relay achieve this? I need something that can also put off the inverter when I am on grid to save my battery from ideal power consumption of the inverter

You will need 2 relays
Or a double pole double throw relay

One will attend to the load transfer then the other one will take care of the inverter.

I understand you don't have the materials or need to do a diy project at present. For example The guy doing his own up there might need it for himself (hence the justification for his spendings) OR someone paid him to build a battery backup and he chose to document his build for us here to learn. That's what a diy thread is about.

I don't expect you to run out and buy parts to discribe a build to whoever asks for help here . . . it's just that I expect you to first list out materials the person needs and bit of the process to be followed to achieve what the person wants to achieve.

It's all good sha, I'm enjoying the thread. I myself M in the middle of a build concerning something else but I need a battery backup hence my interest in this thread.

No wahala chief.
Keep following and contributing....

Document the project you are building now .

You never can tell who might need it too

FourQu:
Even if I'm not a newbie don't you believe there might be other newbies looking at the thread to see if they can learn one or two things from people like you?

Why hide knowledge behind a pay wall on a DIY thread? See the guy documenting his own build up there, that is exactly what a diy thread is supposed to be comprised of.

People building stuffs and posting updates for OTHERS TO LEARN from

If you will fund the process,I don't have problem in doing it.

The person documenting is not telling you how much he is spending.

I have explained the process of achieving that changeover switch and charging stuff....

If you need to see the whole hardware, money would be spent. I get satchet inverter we fit use (you made me to go and check my scraps)

FourQu:
So you've never come across the word 'newbie' before?

You no dey sound like newbie.

You be SNR man

Even newbie self dey get patience to learn and follow the process.

As newbie, if you can fund the project you can learn and build yours yourself

FourQu:
It's like you don't understand what DIY means

D o
I t
Y ourself

It means I want to do it by myself. I want to buy the needed materials by myself. I want to connect everything by myself. I want to install it by myself. i understand the risks involved and still want to LEARN HOW TO DO IT FOR MYSELF !!!

If anybody feels it's too much then they can contact you for help, but FIRST offering to only help someone achieve a task here for a fee is against the core values of DIY you need to share with people how you do stuffs so they can then go ahead to Do It For Themselves . . . You get?

I no understand una. Go to DIY forums or threads on all other websites and check how it's done. Why are the Nigerians method always different

Leveraging people experience on A DIY is also against the ethics of DIY.

Because think about it, why do I have to share my experience if you decide to DO IT YOURSELF (DIY).

By DIY you learn everything yourself and ask questions when you are stuck.

You never do anything you dey ask question and process?.

Take your time and extract information research them then implement.

Those diy forums you are calling Will still ask for your progress.

FourQu:
Thank you 😊

This is exactly what the thread was intended for 💯

Now a DIY enthusiast would know how to begin their tinkering and what materials to have on hand

No go burn your house you will be exposed to high voltage be careful
Goodluck on your quest.

Scientheosopher:
You're wrong!

Some people, like me, are here to learn so that we won't be cheated.

You pay to learn, you no pay, you will all learn from experience.

FourQu:
Is that why you deliberately left out mentioning the parts that cost the said amount? 🤔

I mean, you said you did yours right? You must have a parts list or schematic don't you? unless sharing is an issue i don't see why you'd make it harder for someone else to be able to do what you claimed you did

After all, this is a DIY aka hobbyist thread

I have not done it yet.

But it's something that I can do .


For the parts you will need a relays, resistor, capacitors, diode, transistor, Vero board, soldering led.

Inverter uses the same thing just that it's microcontroller controlled.

The block diagram is something like this

Mains=> rectifiers> switch=> relays =>out put

The relay will be having 2 power sources

FourQu:
This is a DIY thread

Stop telling people to pay you for stuffs 😒 everybody here wants to DIY

I only told him the cost.
Just like say it will cost you 100k to get a 60A lithium battery build.

saint2ace:
Can you share steps and resources to achieve this?

If you are good with electronics, you can put together a relay circuit to do the switching when there is mains.

Check youtube

sonickay:
I have an external charger connected to a socket linked to permanently to grid. When I am going out, I change over to inverter while the external the charger plugged in to grid to charge the inverter.

I will like setup to switch back and forth whenever there is grid power.

I am in Lagos

When do you want it done. It should cost around 20k to add that feature to the inverter.

sonickay:
suoer2kv modified sine wave

I can build an automatic change over for you. It will transfer load,put of the inverter and activate your charger (that's of if you have an external charger)
