I checked your thread,
Which kind of calculation is this, multiplying 84Ah x 12v and the answer being in Ah instead of Wh?
You now used 70 which may be in amperes to divide 1008ah to get 14 hours.

Check your calculations as it is wrong especially the units.

Good stuff. I recently watched an expert analyze this on Bloomberg. Green energy only becomes viable if an economic activity is brought into the mix.

Ovaltine:


Interesting, my fridge takes stable 100w but need about 800w starting power which lasts for less than a second. My 5kva gen will make noise for a second or two anytime I plug the fridge.

I have been sceptical about plugging my fridge on the unit despite my research and the fact that it is a power-saving unit as well.
I use less than 25% capacity of the inverter during the day, so there is enough room for the surge requirement.

Fridge defrosting is the only reason I put on the gen. What do you say?

Specs are:
Rating: 252KWh/annum
Operating current: 0.8A
Total input power: 100w
Lamp power: 10w
Frequency: 50hz
Voltage: 220-240v

Mods, I don't know the right thread to post this. If romance section isn't the right thread, you can move it to the appropriate section.


Moved into a new apartment and realized the light isn't too good. Average of 6 to 10 hours per day and sometimes, there won't be light for like 3 days on a stretch.

I do freelance, love watching movies, I have a small fridge which serves me cold water, I need fan to cushion the heat. This implies that I need a constant light and with the epileptic light situation around, I felt I needed to do something.


My first thought was to get a generator. Average 1kva generator cost 80- 100k. I will have to be buying fuel, buying oil and also servicing the generator regularly.

I almost bought a new generator from jumia during the black Friday sales until I heard the rumors that fuel will likely to be sold for 320/ litre in 2022, I had to abort the generator plan and seek for alternative.


Then the thought of inverter came in. To figure out the specific watt to purchase, I first analyze the power rating of all my electronics.

1 dc led TV - 12v 3A which equals 36watt,
1 gotv - 12v 1A which equals 12wat,
1 dc standing fan in living room of 12v 2A which equals 24watt,
My laptop of 18v 2.3A which equals 41.4 watt,
1 table top fridge of 45watt,
6 energy saving bulbs of 5w each in entire apartment (bedroom, living room, toilet, kitchen, corridors, which equals 30watt
Phone chargers of 5v 2A which equals 10w.
1 wall fan in the bedroom of 45w

When I summed all the power ratings, I arrived at 243.4 watt in total.


So with miscellaneous appliances like woofer and the likes. I concluded And settled for 500w inverter.

hello

Pls what kinda fridge do u use..

Here's a clear one I won a use
Check out this product I found:
https://www./092-dr-92litre-single-door-refrigerator-hisense-mpg1253375.html?utm_medium=social&utm_campaign=pdpshare-apps

What do u think the power of this is..how many watts

PeaceJoyLove:


Discharging to 50% is not recommended for some batteries. Professionally will tell you that for you to enjoy it, the lowest it should reach is 70%. 50% is too low. Go and check most systems connected by real professionals and not these Nigerian technicians. Its btw 60 and 70%. Diacharging to level 50% is too dangerous. Though, it will last longer than discharging to 10% to 40%. If you want your battery remain as new as you bought it, it should be around 60 - 70%. Always aim at 70% and let it drain further on rare occassions to 60%.

jerobua:
Nice one, I commend your effort being your first DIY installation, You saved some cost but it will only be for a short while. As time goes on when you broaden your knowledge on Solar inverter electricity, you will be able to correct certain things..... I will highlight a little for you to research on
Firstly, your Solar inverter is mostly likely not a pure sine inverter and that's why it is cheap, it might even be a square wave form inverter which could damage your electronics in the long run.
A single Mono panel (180watts) won't be able to able to charge your GBM 180Ah battery sufficiently on a daily basis, this will affect the life of your battery
You could have waited a little while to buy a quality battery that hasn't stayed more than 6months, RITAR, GENUS, ADDO, QUANTA. but also know that battery purchase is also luck, it's 50/50 no matter the place or warranty given
For your GBM battery to last longer, you need to charge with a smart charger
Lastly, during raining season, you won't have enough sun, you still need a back up generator
I wish you all the best

Correct man

If it can guarantee him electricity to get his freelance work done without missing deadlines and losing customers (which I have experienced in the past), then it is a perfect investment. This is one thing I am getting having lived in Ghana and Barbados. Constant electricity is a must to be able to generate enough economic activity to work and have a good living.

Nigerians do not know what they are losing by not having enough electricity and then having to depend on noisy, environmentally damaging generators.

aariwa:
Why are people still buying generator and waiting on NEPA instead of this option.I guess it will have to do with ignorance

Ovaltine:


Good option. You refer to DC freezer.
It's such a good option.
I'll have to work on installing DC output to then.

zed7:
I'm quite impressed. I wish I had the patience to DIY. I wish more people will learn to DIY. Fix cars, do their plumbing etc.
We have too many inexperienced workmen charging too much even whilst swindling you when buying parts. Kudos!

lasthero:
Now it's time to run the connection.
The guy I got the inverter from charged me 10k for installation. I told him I will get back to him.


On getting home, I opened the battery, the inverter and the panel. They all came with a manual

The manual was easy to understand and the summary of the installation is "connect positive to positive and connect negative to negative". "Red to red and black to black".

Na so I remove my cloth, pick my screw driver and run the connection as instructed in the manuals and violla, light is here

lasthero:
Now it's time to get battery.

Considering the poor power supply in the area, I needed a battery that will serve me longer hours off grid when there is no nepa light. After searching and researching. I settled for this battery attached below (180ah/12v) for 85,000 naira

Tenshades:


Someone wants to sell a Lithium Iron Phosphate Battery of 12V 150A at 210k...

Apart from the rating difference with yours which is 12V 180A, what are the other major differences?

Thank you

syntekelite:


You said nothing about how you installed the solar panels to face the right angle for optimum sunlight

Bossman:
Absolutely! well said. As long as his bottom line is met, it's a great investment.

Yes, electricity drives everything. It's Just so unfortunate that Nigeria is in this mess!

lasthero:


I don't know much about battery. But from what I read here so far, the lithium battery is better than gel battery

lasthero:


My roofing sheet faced just one side (BQ things). So I just placed it on the roof and clip it to the surface with rope. Judging from how fast it charges the battery, I think it's sitting right. I always have my 100% charge before sunset

Chigorkizz:
Is this set up good for phone charging business?

binladen:
Good job, kindly give us update on the state of your laptop battery in 3-4month( if it ok now), the state of the GBM in 6-9month.

pocohantas:
Very impressive.

Honestly I find it weird that middle class homes still use generator in 2021. Unnecessary noise and air pollution. Some are ignorant and some do not know it could be quite affordable.


This thread should be on FP.

Bantu10:


Can I get these things u listed in a place like abuja?

ignis:
Please can anyone help me with this in kano or minna?

Bigchristo:
So how many appliances can this inverter power in your apartments? I needed something economical like this

FreeStuffsNG:

Nice and commendable. Please kindly work out the payback time by dividing the N152k by your usual daily electricity cost. If you can do that calculation, you can then start counting if you got value from the investment or not. For example, if the battery and/or the inverter pack up before your payback time then it's not cost effective
As at now, it's too early to say if it's money well spent. I commend you greatly though.

queenfav:
E no get how e wan pet am pass,GBM battery will not live up to 1 year.

charlisco:
I will upload mine later, nepa want to kill me here in warri, so I opt in for inverter, planning to get another on, I will b using at home

uuzba:


Well, since you are the one that did the installation and not the electrical guy, you must make sure you follow the basic rule of electronics. And that is, to make sure ALL THE CONNECTIONS ARE VERY TIGHT.
Nothing destroys electronics more than a lose wire that is just lose enough to allow an electric arc/spark to keep jumping across wires. That spark is called Plasma. It is neither a solid, liquid or gas. But it is as hot at 10,000 C. A tiny thing will burn and melt wires and create bigger sparks and more heat till the whole connection will burn.
I hope there's a point for Nepa to charge the inverter and batteries as well. Because you'd be surprised that you won't always get 8 hrs of Sun, Mon - Fri, January - December in this Nigeria.
