If your money is not enough for solar system, you could opt for power station instead. I use this yoobao to power my laptop and fan.

judatech:
Please how does a solar generator work?

It's a storage unit that helps to distribute current to your house or office. You can use solar or electricity to charge it. Depending on the wattage it can carry A.C and fridge for couple of hours.

louken:

What if I buy the one with higher power (over 1000wh)? Can't it power fridge?

Yes it can power you fridge but you have to be mindful of what you plug into the solar gen when the fridge is connected. I will also advice you don't plug deep freezers

cunny88:

The battery is inbuilt, just fix your solar to recieve sunlight, and u r good to go.

Mind you, I only use it for TV, my phones, a laptop and a fan. Its last up to 5-6 hours after full charge

i guess additional battery will up the hours, okay thanks

sukhig solar energy storage system. Lasts about 5-6 hours after full charge, comes with a

sorry how much did u buy urs?

My Guy 350k is too small.

What you can do to help your self, if you are not totally off grid (meaning that you still usually have power once in a while)

Buy Tubular Battery. One good Tubular Battery should be around 200k, find out how much now.

And buy a good inverter around of around 100k.

Use the remaining 50k to buy wire and run its own outlets and light points. You will still have some change from the 50k.

This is called an inverter system. Charge it with light and generator fully and it can take you 1 or 2 days before it needs recharge with those little appliances. It will reduce fuel consumption.

But you will still need to be recharging with generator if there is no light.

But if you want to stay away from generator for a long time. You need like another 400k to get solar s and MPPT solar charger.

For example, I just switched on my Generator 3 days ago and that is the first time in 2 months. And it was because that day there was no sunshine and we still put laptop, TV, 4 lightbulbs, 2 fans etc on it.

Since you don't have the money, do inverter system first. Then later look for additional 400k and then connect it to solar system.

In all you will spend around 750k but you can split it into 350k for inverter, continue to use till you have another money for solar charger.

MPPT Solar charger was N155k when I bought. Don't know how much now. Don't buy PWT as someone suggested, you will not like it.

300watt solar is around 80k to 90k and you need at least 2. One cannot do it at all.

You be man 👍

Buy solar such a way that you can upgrade


Check my page for male cloth at low prices

BigDickProblems:


Thanks for this input.

Sorry, not to bother you, but can you lay emphasis on "not an optimal setup"

I bought a used 250W at 60,000.

Got it for 155k in January, u should know it will be way higher now

dangoteinlaw:
solar is a huge scam am sure the op is a solar installer looking to get clients. Solar is a major scam and those dealing on it are cashing out massively but you won't realize it is a waste of money untill you finally install one.

It is not a scam if you buy direct from China from a reliable seller.

matify83:


You may just be the one edging op to self destruction.

I'm perplexed that you can say what you just typed.

A PWM charge controller does not have the efficiency of converting excess voltage to charging current like an mppt does.

PWM charge controllers are very poor in charging when devices are used simultaneously unlike mppt chargers.

Also, for the specification @op is requesting for, increasing the voltage or numbers of the is a wasted effort because the pwm will reduce it to match the battery voltage and waste the excess hence it's low efficiency.

For op to even use 2-3 s for a 12v battery on a pwm, they must be connected in parallel to boast current and keep voltage at the level of a single or else the pwm will go up in smoke.

With all these considerations, if you still wish @op to go ahead with the obvious "white elephant" project, I wish him safe trip.

I'm totally off grid for 6 years now and I know what's at play here.

Hello bro. Can you point me in the direction of the MPPT charge controller or post a picture here. Also, what's your submission about buying a 100ah or less battery if one is to use it majorly during the afternoons. I'm looking at getting them in bits for installation later.

GerogeI:


That's why he used a 60A charge controller. At max of 8 amps per , in parallel, they add up to 48A. But those 150w s should be like 5 Amps each.

Interesting!

A PMW because of it's low efficiency will invariably reduce every voltage to about 12V averagely.

So, 12 X 48A = 576W.

The only thing saving this charge controller going up in flames is that it can never attain its maximum power generation.

576W is too much power to connect on the 12v system.

The rating for a 60w PWM at 12V should be around 360W or less.

You are tempting fate.

A 60A charge controller has power capacity of 60Ax12v=720W,
576W is well under the rated capacity, Moreover those 150 w s, especially used one will average 3-5Aamps, that's 30A for 6 s. 48A will be peak performance.

Your concern is not genuine. The system is properly sized. The only complaint is that you cannot expand without replacing the charge controller.

Secondly, if am running such a system (which I did for 3 years with 30A PWM controller and 3 x300w s before upgrade), I will always favour more s, above MPPT charge controllers. I only replaced my charge controller when my s exceeded the capacity, then I had genuine reason to invest in a robust 5kw solar hybrid inverter, which I still run for daytime power only.

how long in a day does your laptop and fan last?

cunny88:

Mordecai:
90k for a 250W mono solar
18k for a 30A Pwm solar charge controller
130k for a 100ah 12v gel battery
100k for a 1kva inverter

It's possible, though not an optimal setup. But it will serve till you're ready to upgrade.

Where can I get 100 ah for 130 k, what brand is it?

matify83:


Hmmm!

This is going to be a recipe for disaster.

One 250w solar at Isc of about 7A on a PWM charge controller will never take that battery to a full Bulk charge of 14.4V.

My guy will definitely have issues in less than 3 months after installation because the battery will sulphate from undercharging.

I will advise op get more funds and set-up something that will be worth the effort. An MPPT charge controller will be most appropriate because of its efficiency.
He will need about 2-3 additional s for faster charging.

My guy, just invest the 350k and do a good job later.
You are not ready yet

He is using 100 AH , require 10 to 20 amps charging ,connecting four 100 watts in parallel of 4 amps each will make up to this

BigDickProblems:
Good day guys,

I have 350k set aside for solar installation, and I intend to use it for 2 laptops, 2 Fans and my gadgets. That's all. I don't mind just a solar and one battery.

Kindly advise me if this is feasible. If yes, Where can I get this stuff. Thanks.

. You better use that money and buy biscuit.
If you don't have anything about 1.5M don't bother.

PulaPower:
80% of these so call Solar are fakes, but many Nigerians don’t know..

Just say you can't afford Solar.
I run my home exclusively on Solar

Blaze14k:
That amount is too little unless you want to purchase solar generator. A good solar generator could cost you about 550k without . We also have solar gen of about 300k with that will last couple of hours when fully charged. But if you intend buying an invert it will cost you more,, let's say about 900k or more.

Please can you help with info on this solar gen?

Emmanuel602:


Please can you help with info on this solar gen?

Solar power generator is an integrated Inverter. It generates pure sine wave electricity to carry any electronics and home appliances less than 300W, such as lights, TVs, setup boxes, audio, electric fans, blenders, fridges, computers, and medical equipment

I have learnt small...
OP you can try out the inverter style and later on upgrade.

With that amount, you can get a good product for easy buy . Which you pay up within a yr and 2 months. The solar solution can take kia of all your house hold basic needs. With solar fan . If u are interested chat me up .. for a proper set-up. Irrespective of your location in Nigeria.

this guy who are you, you seem knowledgeable in this area, will 500 to 600k suffice for me ? I intend to do an install in my house in two months time.

I doubt if it's off Grid... He needs 200A batteries and 2pcs of 250w .

Donald7610:
Don't waste your money
It won't be enough

500k to 700k. I am developing alternative storage system that will eliminate expensive batteries.

uvie66:

Yes 600k. Get 220A batteries at ones, 2 s, 1kva inverter,

What is solar generator? Any difference between solar generator and the normal solar and inverter?

Hello.
What does this solar generator mean? Is it different from our normal solar and inveter?

Hybrid600:
I prefer inverter coz I can purchase original products individually and connect myself unlike solar generator wey person no sabi the kind materials wey dem couple inside....
