Good morning gurus in the house,

Pls can gurus help me with quote to install a solar/inverter system in my house with the following load of 1500W.
In addition to the house load, I will also install 4 number batteries.

1) How many solar panels would I need and their sizes
2) What size and type of inverter would be best for this setup
3) What size and type of Charge Controller would be best for this setup
4) What size and type of batteries would be best for this setup

Thanks as I await your responses

Just go with mctfoot's recommendations
But you will just do fine with 3.5 to 5kva inverter
Up your solar PV to about 13 or 15 kw
And if you insist on lead acid batteries you will need atleast 24 batteries assuming the loads will be on 24/7 and managing the batteries will be a lot of work and you will need to dedicate a whole room

It's when you go solar you will realize that there are more cloudy days than sunny days.

why do you all believe he is dead. its all part of the script and i:strongly believe putin knows about this as the guy had to disappear after taking the west money without killing putin

the audio self sounds doctored. was he discussing such a sensitive matter in the public, the audio sounds layered too

first of most countries listed over there are not oil producing states, secondly they have better minimum wage than Nigeria. Let this people stop all these biased comparison e no make sense

I noticed my battery discharge has increased astronomically.

Usually the Battery level do not drop more than 0.2v over night. But now i noticed it is dropping by 2.2v and up to 3V sometimes

Its not like the load has changed, it is the same load i use in the house.

Also, i decided to check the battery levels with a voltmeter and noticed one of the battery is 12.7V and the other was about 10V

What could be wrong and what do you advise i do?

The battery is an i-cell GEL Batteries,

try to charge them separately, see if there is an improvement but the 10v battery is likely shorted

GuestJoe:
Please,can someone help me look into this quotation.

Panels: STC,Rubbitec or Flames
Battery: Tubular (Addo or Houston)

This is to be used by a shop that runs from 8am-8pm and the total calculated load is 3.4kva

will the load be on simultaneously, if no; the panels will suffice else double the panel size

As for the economy mode the number of batteries is grossly underestimated. you will need at least 16 pcs of 220ah batteries

as for the lithium you will need atleast 17kw to 20kw battery.

you may not need that much back up if the loads wont fly simultaneously.

The number of panels will be seriously increased if you will run the loads simultaneously. To be totally off grid you would need would need a min of 32 400w panels

Oppsin:
That's what the man ss listed for me, how true it is as its difficult to trust anyone these days again?

you want to draw 500w from 360w panel. well it wont work. you will need a minimum of 8 pieces of 180watts panel and 4 220ah batteries incase of days with unfavourable weather.

Plus most of these 180 watts panel are actually 150 watts ideally you should have about 10 to 14 panels

you will be needing a bigger charge controller too

brightk:
i beg to disagree sir.

okay sir. its impossible for him to get beyond 2hrs. so far its a lead acid battery.

read about Peukert's law. plus he cant go beyond 50% DOD. 500watts out of a 220ah battery #12v no be joke. the battery voltage will sag so bad within minutes. That's over 50amps draw from one single lead acid battery

it will only work when the sun is up,t that's if panels are added

Oppsin:
I didn't understand the explanation, but will 12v 220AH battery be able to work for 7 hours using 500w of appliance? Thank you

I just had to add it as a note. NL no like numbers

7 what?? you cant get 2hrs self. you will need atleast 4 batteries for that except probably with solar energy complimenting, but on batteries alone, NO

pineed:
Simple answer is No.

why? care to explain. is it not combustible?

quick question..
when the CNG becomes available, hope it will be a suitable substitute for LPG??
Cooking gas dey chop money o. Its back to N750/kg in my area

solareclips:
Good day all,
Please which of these set up will last longer after full charged.
24v 3kva inverter, with 4nos of 220ah battery 2s in parallel, and 48v 3kva inverter , all same loads.
Thanks

Care to explain why

This your story no clear

A 12v solar array can't charge 24v battery

Let the masses breathe. People are already breathing as if they are on life support. This is no longer funny. In a couple of months there will be massive job cuts because companies are not meeting up their revenue generation because of low patronage.

Let the government put the foreign exchange in check. No serious government floats her currency. Almost all storing economies of the world controls their exchange rate to an extent

LLMG:
you mean like the govt sponsored anarchy. Please direct your advice and concerns to the govt on behalf of the the harmless and peaceful protesters.

Don't mind that slow poke. There should be massive protest against the government policies. They in no way favour the masses on the short run or long run.

I was shocked when I wanted to restock rice yesternight only to find out one derica sells for 650 to 700, a bag sells around 39 to 41k.Every other items also had increased astronomically. I just lost about 50% of my purchasing power in two months of this regime. This is pure evil.

The government wants the people to bear the pains for a better tomorrow but they are enjoying jumbo packages. Nigeria can never be good if we don't call a spade a spade.

Forget tribe or religion. Hunger doesn't discriminate o.

If any idiot quotes me and say double your hustle, I'll give it to you blue black.

Like play like play revolution Wan start. The government should be swift else I see this protest degenerating into serious crisis.

When the masses have a common enemy (hunger) to revolt against it is always serious

FreeStuffsNG:
Subsidy removal on petrol has come to stay. We will adjust with time and back to our winning ways as a nation.
God bless Nigeria for ever! Check my signature for free stuffs!

Same subsidy removal he vehemently protested against? Nigerians are too docile. It's morally wrong for him to remove same subsidy he claimed doesn't exist back then. He should first apologize to Nigerians.

Acekidc4:
Problems like this is Suppose to make the Citizens become Innovative and Creative in finding alternative Workable Solutions. This is a good time for we Nigerians to be Creative instead of waiting for government everytime. How many can government do for Us?? We can do a lot of things for ourselves by ourselves. Don't wait for government wey no send una Papa.

We should do alot ourself, what then is the function of the government, what's the use of the free natural resources? It's only in Nigeria people use their money to buy cables for electricity, buy transformers, pay for repairs of the transformers, pay to acquire meters and still pay for the energy.
Go to the police station to report an incidence, you get billed. What exactly is the use of the multiple taxation. To enrich themselves?

Simply because you and your kinds are getting paid does not mean you should be totally shameless. Your likes is the reason why Nigeria will never progress. Call a spade a spade.

We should endure pains while they enjoy luxurious lifestyle. Okay o, continue we will all voice out at some point.

I'm begining to believe that some likes are being bought or the users have multiple accounts to achieve it. If not who in his or her right sense like those first two comments up there.

temi4fash:
Oh.. How do we make it stay full charged after remove the Power source?

Connect a smart charge that will maintain a float voltage. It's not as if it would drain completely if you don't keep it connected. You should only worry if you won't use the battery daily.

temi4fash:
Hello Sirs,

I was not in the house for some days, i noticed my inverter charged my batteries up to 28.6V when still connected to NEPA.

Immediately i put it on load it dropped to 26.5 and rapidly up to 25.9V and stabilises there and do not drop rapidly again.

What can be the problem?

Nothing is wrong with your batteries it's absolutely okay.

dejidotun2000:
A resistive load doesn't draw more current than an inductive load of the same rating, it's the other way round.
A resistive load of 2300W connected to a 230V AC source will draw 10A, an inductive load of same 2300W and power factor of 0.5 will draw a current that is twice what the resistive load draws.

Me I am now confused. OK this is my situation. I have a freezer that draws 0.78amps and a heater that draws 0.77amps both at 230v

My battery remains at 12.5v when it's just the freezer that is turned on but it drops to 12.3v when I put in the heater alone.

. Another scenario is that when I put on the freezer with other appliances that are not resistive that draw a sum of 2.3amps at 230v my batteries remains around 12. 4 to 12.3v but when I turn on just a small oven that draws about 2.45amps at 230v the batteries rapidly drops to 12.1v

mctfopt:
Sure. The amount of current drawn by a load is determined by its resistance and the voltage applied to it. According to Ohm's law, current is equal to voltage divided by resistance. So, for a given voltage, a load with a higher resistance will draw more current.

A resistive load is a load that simply converts electrical energy into heat. The resistance of a resistive load is constant, so the current drawn by a resistive load will be directly proportional to the voltage applied to it.

An inductive load is a load that contains an inductor. An inductor is a coil of wire that stores energy in the form of a magnetic field. When current flows through an inductor, the magnetic field builds up. When the current stops flowing, the magnetic field collapses, creating a voltage that opposes the current flow. This voltage is called back EMF.

The back EMF in an inductor delays the current flow, so the current in an inductive load is not in phase with the voltage. This is why inductive loads have a lower power factor than resistive loads.

The power factor of a load is a measure of how efficiently the load converts electrical energy into useful work. A power factor of 1 means that all of the electrical energy is converted into useful work. A power factor of less than 1 means that some of the electrical energy is lost as heat.

Because of the back EMF, an inductive load has a lower power factor than a resistive load. This means that for a given voltage, an inductive load will draw leas current than a resistive load of the same power rating.

Thanks alot

Can someone please explain why a resistive load draw more amps than inductive load of same power rating.

Hello house, can lead acid battery users share their battery's discharge character on different load
Eg 12.6v on 20watts load
12.5v on 100watts load
12.4 on 150watts load
25.2v on 30watts load etc

Please these behaviors should be based on 100% SOC. Please state the battery AMPS etc

The truth must be said! Asiwaju has outperformed beyond imaginations.

Out performed? Hmm

Biodun556:
Naira is not devalued

Dollar was scarce because Buhari fix the exchange rate

What sort of thing are u saying. It was scarce because we are not earning enough. It's simply because of balance of payments deficit.

So when the rate floats dollar supply will improve right?

imbless:
Many people in this forum is unintelligent and daft, y'all think you can buy dollar over the counter inside banks ? SMH!!
1. Naira has been devalued
2. Dollar is scarce because Nigeria is still importing more, and common sense should tell you that if a commodity is scare, and there's high demand for that commodity, the price will skyrocket,
3. Nigeria depends on nothing more than crude oil to bring in FX, our Reserves has depleted because mismanagement from previous government.

Now tell me how naira will appreciate?
Nigerians na who do una this thing?
Even some people you think is intelligent is daft!!
SMH!!

Sincerely I keep wondering how people believe it's an achievement to devalue the currency, remove subsidies etc

I'm quite surprised at the way people are trying to make devaluing your currency an achievement. For goodness sake Nigerians are really gullible people.

Praising the president for losing about 50% of the value of our currency in 2weeks. Your savings in naira just lost about half its value and you consider this wonderful.

The only thing that impresses me about this is how he is doing all these with little resistance from the masses.

Fuel sells around 500 to 600 yet we are praising him. He really has a great influence over the people or should I just say people are deliberately foolish.

Once again there is no such thing as market forces without influence. For those of you thinking competition will force prices down, you have no idea how business works. The whales will only try to eliminate the smaller fishes before going into beast mode. The whales will simply form a price rings. Take OPEC for example an association of competitors whose aim is to increase the price

Some strong economies of the world do not allow their currencies to float because of the exploitative nature of capitalism. Forget all these nonsense about these floating of the currency, it's just a condition that needs to be met to obtain further loans.

Don't get me wrong I'm not saying these moves are right or wrong, I'm just saying none of these policies are beneficial to the poor anytime soon.

Brace up for some serious inflation

bbeckky:
Good morning house. Pls how good is star plus tubular battery

How would anyone know. It's a new product buy and try. Well I currently use them and I'm hoping to get the best out of them.

There isn't any information abt the charging profile on the battery or the carton, no C ratings either. Though it is 220ah @ C/20. It Comes with 18months warranty.
