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

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.

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.

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

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.

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.

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.

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

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.

That's why he used a 60A charge controller. At max of 8 amps per panel, in parallel, they add up to 48A. But those 150w panels 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.

I don't know why Nigerians will always come online to lie to scare others , solar get levels
While most people might be correct that your 300k is too low , but it is not totally true

Let's see

12v 150w solar panel is around 50k for my area anambra state but for Lagos it is way cheaper

You will need just three - so that even when small sunshine your battery is full under 3 hours

3 12v 150w panel 50k*3 = 150k

60A pwm controller this is very important you will learn why in future and based on price of 30a it is foolishness that will make you not buy 60A controller

1 60A pwm controller = 28k

1 pure wave inverter 500watts or even lower like 300watts = 30k lower if you see 300watts

Na here it gets a little dicey

Go for 75a or 100a battery
If you go for 100a depending on location u might need extra 20k to 30k
But for 75a battery you won't need extra money

Remember money for wire and to pay installer , circuit breakers are not included


You 300k will get you a well and able doing solar setup that will work well during the day but not that long for night highest 2 to 3 hours in the night

If you want put to 8hours or more in the future just buy one extra panel and 200a battery and add to the setup and you are good to go


No be AI writeup be this na real life experience I have done years back and still doing it

A picture attached below is one I did last year ending total coz was 550k

6panels , 200a battery, 1k inverter , 60a controller
I buy controller and inverter for AliExpress both didn't even cost up to 60k then na for panel and battery these people take chop me






I'm curious to know how you connected 6 x 150W solar panels to a 12v battery without surpassing the power setting for 12v on a PWM charge controller?

You are wrong! Stop misleading ignorant peps with things you know nothing about. Even 200w monocrystalline panel charges 100 ah ba3 for 10.5 to 14.any full charge in 6-7 hours here

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 panel 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 panels 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 panel 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.

90k for a 250W mono solar panel
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.

Hmmm!

This is going to be a recipe for disaster.

One 250w solar panel 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 panels for faster charging.

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