Nice thread

lasthero:
Total cost:

Battery : 85k
Solar : 30k
Inverter : 35k

Total: 150,000 naira.

I bought wires 2k

Making 152,000.

My observations so far
It takes 5 to 8 hours of sunshine to charge the battery from 0 to 100% depending on the sunlight intensity.

And guess what guys. When all the house load are on it, it lasted me up to 8 hours to use up a single charge. But when I put of the fridge, the 45watt fan and when my laptop isn't in use, it takes more than 12 hours and that's exactly what I needed.

Burning 8 to 12 hours on petrol daily will send me back to my village.


Thanks for coming to my Ted talk

Running your battery flat will only lead to change of battery in a couple of months. Lead acid batteries are not meant to be fully discharged, at most 50% if you want to be using that battery in the nearest future

Yeah I know. I only did that on first use to estimate the usage duration. I don't use beyond 20% since then. And the inverter is kind of smart, it turns of AC output when battery is a bit below 20%, and leaves only the 5v and 12v DC on

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.

I looked around online on jumia, jiji and konga for ranges of 500watt inverters and chargers. After a rigorous check and comparison, I settled for this (picture attached) for 35k.

Where did you get the inverter from

BTS store at surulere.

They have store on jiji and jumia too.

Ok

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.

It seems it's out of stock.

Didn't see anywhere online

what about charge controller?

The online price is 38k. But negotiate it to 35k, they will sell. That's what I did


Also on jumia.

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.

what about charge controller?

The inverter is a 2 in 1. It has both solar charge controller and 800va - 500w inverter

you are so smart....kudos to you

Don't let it discharge beyond 50% else the batteries won't last..

Very good post. These are the kinds of informative posts I like to see on nairaland frontpage

Ikorodu, Lagos

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

Affordable laptop powerbank and Rechargeable powerbank for laptops built with litium battery

Prize range from 25,000 upward

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

Impressive

This is good

hahahahaha
weldone bro

Nigerians have accepted their fate with electricity. It is a failed country. lol, some west african countries have more stable electricity than Nigeria.

Shame.

Brotherly, Abeg what's your location? Could you help with same installation for a fee?

Not trying to rain on OPs parade. I just did a 1.5kw setup and looking to monitor its performance. Biggest expense is often the Solar and the Charge Controller. If you want a reference I can give you one and you start the conversation with them. I've know this person for at least 7 years as a former colleague. He is good

This is a very nice thread. I hope to install something similar in my (parent's) house someday. Thanks OP for the knowledge.

This is impressive and highly enlightening...

Just imagine how much one needs to spend just to augment power supply in a nation that supplies stable power to neighboring Nomads!

The next challenge is how to charge the battery.
I have two options, charge with light or with sun.

I thought about it. To charge with light, It will add to the consuming units. And also, the light isn't even stable. Here is sun on the other hand, completely free from baba God and it shines every single day.

I decided to opt for the green and free route, solar energy.

I bought the solar (150w mono) attached for 30k

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

I just did a solar setup yesterday and I have been evaluating. It's nice to see the inverter start charging from 7am until 6pm. If you want a I can share my solar guy's for you to get a quote
