I agree "she will go far" but you will agree with me that she will need money for transportation.

LOL!!

Coolgent:
Wow that's good.
Can it power one AC from evening to morning?

That wouldn't be possible with my set up but not impossible with a much larger set up.

Olympic exercise book was my favorite those days

2A, 2B, 2C and 2D Olympic exercise books.

How time flies,

There is dignity in labour.

This may even be the job that saw her through school and puts food on the family table.

The dad is old and looks frail now and sure needs some helping hand with his enterprise.

I salute her courage.

She will go far

Well done boss,
Pls, can I connect 3 300watt panel in parallel to a 60A pwm charge controller without Frying the controller.

Yes but it is a waste of wattage as all the energy produced by the 3 panels in parallel is reduced to around 12 - 16 volt maximum and a summation of the current of each individual panel.

I conducted an experiment of connecting 4 Canadian solar panels at 350w each [ all parallel] to a 60W pwm charge controller during the course of this post.

The maximum charging current I ever recorded was 20A.

With an mppt charge controller of same amperage, your current can go as high as 40 - 59A depending on the time of the day.
Charging time is also reduced and you attain float charge even before 2pm daily.

Always ensure that your batteries are fully charged before use.

Using the effort he used to understand the clotting cascade and origins and insertions of muscles is like training in high altitude and then coming down to sea level to perform aerobics.

Kudos to you sir.

He told us he was going to "widen the tax net and reduce our purchasing power".

It wasn't a Freudian slip as he was enveloped by "courage" on day 1 to announce the demise of fuel subsidy and has not looked back ever since, churning out weekly policies that further emasculate the people.

With the new cyber security tax, vat tax, and transfer tax set for implementation, we are in for a hellish ride as the government seeks to "Widen the tax net and reduce our purchasing power"

I wonder how the crew will cope if this ship runs out of battery power in the middle of the ocean

Backup generators.

Impressive feat though

It was a fun filled childhood with you ovularia, ramota, jegede sokoya and of course natty and zebby. Not forgetting clarus and his co-worker gringory

You made us happy back then as we looked forward to every episode of the popular sitcom on NTA.

RIP Ovularia peterside

Which kind yeye ozempic

Ozempic is a diabetes drug which some misuse for weight loss purposes with severe side effects
Pls don’t advertise OZEMPIC for weight loss , it’s not everyone that lose weight with the aid of drugs

Ozempic is not FDA-approved for treating weight loss. However, Wegovy, a medication that contains higher amounts of semaglutide than Ozempic, is FDA-approved for chronic weight management in individuals with a body mass index (BMI) of 30 and higher or 27 and higher in individuals with a weight-related health condition

Matheusmartin:
...
Which yeye exercise and dieting??


If he's not sick,he probably Shed so much weight in the shortest possible time with the help of the wonder drug OZEMPIC.

Don't mind them.

They are using dieting and exercise to deceive the gullible.

They are mostly on Wegovy and Ozempic, the Semaglutide originally for management of Type 2 diabetes but found to be very effective in drastic weight loss with little side effects.

Our popular talk host billionaire - Oprah Winfield and the richest man on earth "Oga" Musk are rumoured to be on it.
One of the Kardashians is also on Ozempic.

High probability for debt forgiveness and write-off.

Invariably, it is the other bands (B to E) that have been impacted negatively by the unending power rationing and blackouts as emphasis has been shifted to providing Band A feeders with sufficient power to avoid downgrading and loss of revenue.

This is one of many unintended consequences of the tariff dichotomy that was either not envisaged ab initio or stealthily hidden in plain sight from consumers until it dawned on us that we just had a hair cut in absentia.

Like our typical "fire brigade" attitude to things generally, I believe notice was given to the occupants of the building but our characteristic lackadaisical posture made him delay until "Babylon" came calling.

He should have moved his things into storage a long time ago while he sought out his housing predicament.

For this to be happening the second time only shows who he is.

Voodoo is real but you have to be at your best to maintain its strict laws.

One slip and you are a dead man walking.

It always fails anyway!

Sammybase, you are too big for this.

There is absolutely no wisdom selling your future to karma for a porridge you do not really need.

God's blessings are in hundred folds. So does karma take its toll in hundreds of folds.

You have heaped burning coal into your bossom.

Restitute or suffer the consequences.

All the parameters measured were normal until the morphological appearance showed otherwise.

However, with total abnormality of 38%, it means 62% are healthy cells which is nothing to worry about.


Go and sin no more

What a pity!

Greed was at the center of this disgrace.

Hope others learn a lesson from this misadventure.

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

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.

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.

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.

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

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?

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.

E still dey body!

They were the "break dancers" of yester-years when men were boys.
