A lot more people are embracing alternative source of power and as it is worth every penny. I always recommend Lithium battery for portability and longetivity, i assembled LiFePo4 battery for inverter and Laptop use as external battery. Presently we have 3 size capacities 300wh, 480wh and 1260wh and they have been making the difference for our clients. We are reachable on 080653..16307 www.cooldipo.com

Good job and highly commendable. However, it seems like you didn’t get a charge controller for the solar . Connecting an MPPT charge controller between the solar and battery will regulate the rate of power the solar sends to your battery for charging. This will, in turn, help to improve the battery’s longevity.

You can consider getting the MPPT charge controller anytime you have some spare cash. Kudos for a job well done.

Pls how much is the mppt?

Which way to go bro?

akpota:
boss I am a solar guy who loves DIY and done a lot of stuff like this.
You could even go cheaper if I saw this post before. But please don’t drain deep cycle to 0%. I would advice keep it within 50% depth of discharge(DOD).
Anyways me I don leave una for deep cycle batteries wahala lolz.

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

This is so educative and informative. Nice of you

@Op, where did you hang the solar s

Well done.
The first few days of Solar are always exciting, since you are entering a new phase of getting Electricity.

But the issues start a few Months later (if you Battery is the likes of GBM) or about two years after, if your load is beyond your Battery capacity and you are drawing down the battery heavily.

As long as you can use Inverter Appliances (Fridge, LED Bulbs, Fan) and a good battery, you may be able to enjoy the setup for some years.
But if anyone tells you that it is cheaper to run on renewable Energy, na lie o.

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

A series connection of the s with mppt will do just that.

Post bookmarked.

Which battery be the best and can last at most 4yrs under supervised usage?

Quanta or exide.The latest Mpower indian battery is good too, one of 220ah.

This is mine...got it for 6 months now...can go 12 hours with jux my fan and balbs on.

Good information.

Skillsnigeria:
That's good, you should have bought original battery brand and not gbm. But you can still manage it

Pls name me a good battery brand

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

If you are in ibadan.We do installation of inverters

lasthero:


Ikorodu, Lagos

Where in ikorodu ?

Hello, please can you put the system on charge and go out to work? What happens if the battery over charge?. Finally, is it safe to use the system while charging?

Watch out, APC gov't will find a way to make this process more difficult

What can I say?

Excellent!!!

airsaylongcome:


The problem is that solar s are not very efficient converting solar to electricity. The best you can get is 23% efficiency which is very bad to be honest. But considering the free availability of solar and potential cost of petrol in the new year, it makes a lot of sense to tap whatever you can from solar.

My own worry is that make state or federal governments no go dey bill people for owning solar s like Lagos was planning to bill people for boreholes

E go soon get to that level... The government like stealing from her citizens

It's waaay cheaper, I have my own set up with two 200ah batteries, my own can charge with both solar & NEPA..I have being using same battery for almost 4 years now, not much decline, but I intend to swap them with new ones when they clock 5

Ajibam:


Hey Bro

can you share more details about this and tag how I can get all of them?

alright bro first of all let me tell you this setup has its limitations. its an energy storing setup and you can only store so much energy unless you want to go crazy and buy 100 batteries and link them all up. do you have space for 100 batteries ? and do you have the money for 100 batteries ? each battery is like 90k. and so as you can see ? you can only store so much energy with this setup and as such this setup is meant for minimalist living meaning someone who wants electricity to run for 24 hours so that they can power their laptop and lights and fans even when nepa has strike again. its advisable to only power these low power items with this setup. trying to power an ac with this unit will destroy the battery quickly. and so now that i have explained the limitations here is what you do. got the most powerful battery deep cycle which i believe is 200ah. then buy an inverter. i have a 500 watts inverter. connect them together positive to positive, negative to negative. then connect the battery to the mains and your appliances to the inverter. and thats it. 24 7 electricity forever assuming nepa does not take your light for more than 2 days at a time ( if nepa takes it for more than 2 days all the juice in this setup will be drained unless you buy more batteries and connect it parralel ). and if light comes back your unit starts charging again and when it goes your unit takes over powering your gadgets without missing a beat. and you can be like OP and introduce solar s to the unit. monocrystalline ones in which case when they take light for more than 2 days you are not affected. everything you get from konga.com is where i got mine from in 2019

Ajeh you have done the best thing, your type is needed for minister of finance not some goro chewing almajiris from lifeless mannequin in aso rock.

Pls name me a good battery brand

There many original battery brand, but they are more expensive than the fake ones, you can buy original quanta, ritar, full river and others original brand which I don't want to mention here, make he no be like say I dey for them.

Ovaltine:
Your DIY mentality is commendable.
I am sure it wasn't as simple as red to red or black to black but you still nailed it.

The wiring can be neater.
I suppose you ran a continuity test on the whole system and you separated your heavy load via wiring as well. You don't want a visitor to mistakenly plug a 2500w steam iron into your unit.

Oh. I see there is a socket. Does this mean an extension is sending power to your appliances?

I recently did a 3kva 24v PSW Beaver, 2x 200ah 12v Gel Ritar , 2x 300w mono installation.

I had to pay the optional installation fee despite my strong background in electricals. Its just easier to pay experts these days.

What did it cost you to set this up?

can i get or link of where u bought inverter and battery?

lasthero:
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.

You should take power factor and inverter efficiency into consideration. Power factor for reactive loads and maybe a 25% derating

airsaylongcome:


For inverter setups, the absolute best batteries would be Lithium batteries that you can discharge to a depth of 90%. But they are damned expensive. And scarce die to tech shortage from Covid.

Cost is not the only issue, they often develop BMS

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

Get solar freezer and stay worry free

Can you install for me. I can get the materials.

But can you install for me in Benin City & Ibadan, Oyo State?

Let me know, then send me your number!

Ogbrave:
This is mine...got it for 6 months now...can go 12 hours with jux my fan and balbs on.

I see just one battery. What's the capacity?

Is the battery connected to any solar s? If yes, how many? And what's their respective wat?
