In other words, you dont rate solar generators?

Yah in terms of maintenance and what you want to carry.

Okay.
Tankz so much.
I appreciate all your response.

Justinlean02:
The battery capacity is about 1020wh and can last 10hrs

I am looking at getting something as a temporary solution that can power 2 laptops and 1 standing fan plus charge 1 phone and can run at least 20 to 24 hours in a day. What do you think of the below solutions? Are they good? Never used the brands before. Which will meet my requirements? Please help. Thank you.

rinaballa:
for where?

I bought it here on nairaland

Greenscientist:


That ok nah.

I only enjoy day time 8am-6pm. My battery has spoilt but the panel is still serving me.

Can I get the breakdown of what you spent?

Used Canadian mono panel 200w - 42k
6mm cable(4mm is fine tho) 9 yards - 24k
Pwm controller - 10k
Inverter 500w - 25k
Car Battery 49k

Total - 150k

This is the second car battery I'm using.First one lasted a year an half. It's better to purchase a solar battery instead if you can afford it.

Donald7610:

The recipe is okay
You're wrong bro
7A good to charge 100a battery

I'm not disputing that 7A will not charge a 100ah battery, the crust of the matter is that it will take days to achieve a 14.4v bulk charge and the battery may never get to float especially on a pwm charger.

A battery requires a current 10 - 20% of it's rated Ampere hours to be fully charged and on a pwm with it's inefficiency, you can't use it while charging simultaneously.

uvie66:
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.

Sorry for replying late. Work calls!!

If you are sourcing the components yourself without middle men, you might just be able to set up something worthwhile with 600k.

I always advise you start off with an 80A to 120A mppt solar charge controller. If you ever need to scale up your battery bank or increase the numbers of your panels, the charge controller will not be a limiting factor.

The inverter will most definitely depend on the load you want to power.
The rule of thumb is to add 1000w to the largest single load in your home. E. G. If your pressing iron is 1200w, then you are better off with a 2.5kva inverter since you won't want to switch other gadgets off while ironing.

I hope I have done justice to your enquiry?

eacoder:




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

You are absolutely right.
However, their plan is to use one 250W solar panel which I found worrisome.

4 panels in parallel will be just fine like you suggested.

Thanks

amicdan:
60 AMP PWM CC

Thanks for the picture on the power requirement specifications for various battery connection.

Must admit I'm ignorant of the workings of the pwm save for the theory behind it.

I am however curious that a 12v can carry as much as 780W on this PWM charger.

Hope these Chinese guys won't end up burning down someone's property?

Like I alluded in an earlier post, it's the inefficiency of the pwm that stops must home going up in flames.

Very grateful for sharing.

GerogeI:

A 60A charge controller has power capacity of 60Ax12v=720W,
576W is well under the rated capacity, Moreover those 150 w panels, especially used one will average 3-5Aamps, that's 30A for 6 panels. 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 panels before upgrade), I will always favour more panels, above MPPT charge controllers. I only replaced my charge controller when my panels 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.

I give it to you sir.

Never knew the 60A PWM can carry such power on a 12v battery until someone posted its specs for me.

However, lts still difficult simultaneously drawing power from the battery and having it charged using the PWM system unlike with an mppt that can generate a charging current as high as 59A for a similar 60A charger.

The inefficiency of a pwm is responsible for most disgruntled solar energy users in Nigeria.

Thanks for your valid contribution.

My own opinion, "normal solar and inverter"

Love800:
Okay.
That means solar generator and normal solar and inverter are the same thing. No difference.

But, which one is more better and effective?

micxwell:

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.

A 100Ah battery should be your basic minimum.

Even if you intend using it mostly during the day, it still doesn't negate the fact that the battery must be fully charged each day after use.

I will advocate you get a 30A mppt charger but scalability will be difficult beyond a certain threshold in future.

diamond68:
you are talking rubbish. I had a setup with one 150kw solar panel 200 amp hour battery and 500 watt inverter and it worked perfectly the trick is to also connect it to main electricity supply so it’s powered by Nepa when there is light

You are confusing the post here.

Firstly, your system is grid charged and not solely charged using solar power.

Secondly,150KW solar panel = 1500W panel as a single panel does not exist as I know it.

Thirdly, let's agree that you meant 150W solar panel. This will have maximum generated current of 8A as Isc (short circuit current) .
Your 200Ah battery requires a charging current of at least 10% of its rating, i.e 20A to be charged effectively and efficiently.

If not for your grid charging, your battery would have been long dead from undercharging.

We don't play TRICKS here

I approached a guy close to my neighbor and he told me 1 million naira for inverter at my place

That's too high

Harfisco:



That's too high

Yea is too high.... all I need is just to power my laptop, Samsung 42inches tv, 2 standing fan and light.

Just need a reasonable offer to help with

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 panel and one battery.

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

With 350k you will get a solar Generator that will carry your basic home Appliances, i am available to guide you more

The benefits of MPPT is not debatable, however cost has to balance budget, for a funding strapped enthusiast. Rather than going for a small MPPT charge controller, build up you solar panels with PMW, when sufficient, buy a high capacity 5 kW MPPT or Hybrid

Harfisco:

Just incase you'll able to get a pocket friendly solar system... please do feel free to reach out and I'll too will reach out if am able to get one

Thanks to all the gurus for the info. I have at least 6 to 8 hrs electricity in my area so I don't want panels yet. What is the best type and rating of charger will charge a 220ah tabular ba3?

Thanks

fashrola:


What's the brand name and model?

I bought it unbranded as a sample. But its manufactured by Fouyan Electronic, you will see many adverts with third party OEM branding. Here is a link

https://x.alibaba.com/AwIpTb?ck=pdp

Caveat: This system will only bypass battery to give you maximum solar output only when the sun is high and intense. If the weather is gloomy or low cast, as if its about to rain, it will turn off and start beeping alarm for battery. I use it with a changeover ßwitch

How many Panels does this hybrid inverter need to adequately supply power direct at day and if i need little power by night to power fans, a laptop and charge phones, can 1 220Ah Tubular battery serve. Thanks

GerogeI:


Yes, that's what we knew previously, that inverters require either a battery or a reference voltage to work. Am not sure why.

But I own a Chinese inverter that will gladly bypass the battery once the Sun is reasonably bright at around 8 -10am. So I now reserve my old dead batteries are for refrigerator in day time, at night - phones and lighting.

Can you please share more information about this your inverter, picture inclusive and how to get it thanks.

Harfisco:

Vicky2k:

Every thing depends on how you configur it, bearing two limits in mind.

1 - The minimum voltage for the 5kw version is 120volts. Maximum is 500volts. If you do not have enough panels to get 120volt, the controller will not even power on. Each 300w panel can give you at least 30v, so you need about 4 before this inverter will power up. It has a 2kw version with less voltage requirements

Also 500volt maximum means you can put panels in series and parallel, but your real upper limit is the 80Amps maximum current.

As for night use. It takes 48 volts. So one single battery cannot work on the 5kw version. The 2 kW models uses 24 volts. Its better to buy 4 units of 50ah or 100 AH batteries than a single 220AH.

To keep costs low, you can use 4 car batteries, for light and phones, but if you add fan and laptop the car batteries will not last long. You can use discarded car batteries as long as they can maintain 12v.

Knowledge Transfer
Let me also tell you how to resolve badly sulphates batteries. This mean the battery is still internally not corroded, but has sulphur deposits.
Go to pharmacy, by epson salt. Mix with rain water and put small quantities in each battery cell. Get an inverter welding machine, connect positive to battery positive and negative to battery negative. Pump the battery with 50 A current for 4 mins, allow it to cool for 5mins. Repeat, and gradually be increasing the current till you get to 80Amp. You can also use a battery charger, but most will not give more than 20A current. After 5 to 10 cycles your battery should be as good as new if the internal parts are not corroded and falling apart.
Note doing this longer than 3 to 4 mins will either burnout your inverter welding machine or cause over heating and possible explosion of your battery. So stick to the timing. It works for deep cycle batteries too.

The inverter is rated 500w, but you should know most investers have an efficiency rate between 70 - 90 percent.. So the highest load I have connect to it is my blender rated 350w(only mostly during the day or at full charge)

I'm guessing your question is about what devices I connect to the system. It's mainly my laptop 50 w
Rechargeable fan 25w
Phone and other small devices around 20w

I use for about 5 hours( although I don't usually leave my laptop connected once it's full)

So with a 500w inverter, you can plug in any device as it doesn't exceed 350w.

For higher loads, purchase a higher rated inverter 1kv or more. But u should know more loads will consume more power so you have to invest in batteries and ultimately more solar panels.
