U'll need to buy an mppt charge controller. Get any of the guru in d house to help u reinstall ur system

Dreamflyin:
Load should be around 700-800w.

Free energy coils?looool. What a nice wiring!

darediamond:
I have th time today to show you my mini Solar Gen. As you can see in the shots, it is a small panel which I refuse to upgrade because I will soon Forget TOTOLLY ABOUT SOLAR GENERATOR LET ALONE THE ALL TIME USELESS GOVERMENTBSUPPLIED POWER VIA another useless vendor name P.H.C.N

The machine with which I am making my new Free Energy Coils is the Distinct fourth.

Advancing away from solar to concentrated electromagnetic flux? What a joke! U want to create a perpetual motion machine?

darediamond:
I have just replied to a Thomas like you.
Find the reply.
I am advancing away from Solar to become totally indepent in Power Generation.
Attached is an Homemade Machine which fabricated myself and which is meant to make Special Concentrated Flux Electromagnetic Radiant Energy Producer.

Its not well installed else it will last the whole night. Be specific on what 30% load means. How many wattage of load? Or what's the capacity rating of ur inverter? On sunny days what's the average charging current at noon day you've observed? These questions will help De know what's wrong with ur system.

Dreamflyin:
If the Sun is up, it takes me up till 5pm and goes off at 30% load. Without sunlight on batteries, it lasts just 2hrs. Now the whole ish is acting up, its just 30mins.

Nice panel installation but pretty rough connection though.

Nice short clip u gt .. Will try upload some tho !

Forget this grammer, Bubu's incompetence is legendary. The SS/SE do not like him but that is not responsible for his ineptitude, it is inherent

Bolustic:
Dear Op,

From which credible poll did you read that Nigerians have lost trust in the President? The truth is the people who voted him knows the rot of 16 years wouldn't be cleaned in 2 years.

How would you claim you trust someone and still give his opponent over 82% of your votes?

It's better you say the people of SS/SE don't trust him. They never lost trust in PMB coz they never trusted him.

From this statement it shows you have baseless hatred for GEJ. funny thing is that you are a nobody. Nobody in you village has ever achieved half of what GEJ achieved. Yeye dey smell

DropShot:
What have you achieved with your wailing, protesting, destruction and the ultimatums?

No president, past, present or future, can be worse than the Ineffectual Buffoon. Deal with it!

A once presidential candidate who doesn't know what subsidy means! I'm sure he can now define what subsidy is

Let's not go to the extreme here. The op said he can get up to 6hours currently from the batteries but wants to buy more meaning the batteries are not that bad! You make it seems as if we are talking about a battery that is behaving like a capacitor .

mank1234:
That's not entirely true. If you've a 12V battery of which say 2 cell are dead, it will be never charge up to 12V. If connected in parallel with healthy battery, the setup will appear to be optimmaly charged at full charge but as soon as the charging source is removed, the voltage of the setup will reduce to below 12V. The dead cells will slowly convert the excess energy of the other batteries to heat till it reaches it settling voltage. It will pull it down all the time.

Try this with a dead battery/ new battery and you'll agree to my proposition. Charge them fully, remove the charging source and load and watch what happens within 1hr.

Rocket science!

When you connect the old and new battery together in parallel, the pulling down of the new battery by the old one is just an initial occurrence only and it depends on the state of charge of the old one..there may be no pulling down if they are at same potential. When they say don't mix old and new batteries, its for series arrangement cos the strength of a chain is its weakest link but not in parallel per se. This is not rocket science.

mank1234:
Battery charging process is a function of many parameters whether connected in parallel or series: voltage, current, time and temperature.

In series, same current pass through the old and new batteries and is limited by the old battery due to its higher internal resistance. (The new battery will likely not be affected)

In parallel, the old battery drags the voltage of the newer battery down: this processs involves a sudden discharge of high current (from new bat to old bat) which if done repeatedly tends to reduce the strength of the new battery.

In bank of series and prallel setup, it is more complicated. While some may be undercharging or overcharging. Remember electricity always flows through path of least resistance and in this case newer battery.

It's advisable not to mix batteries of different charge level(ditto old and new batteries)

Maturity at its peak.

Its not as if the battery will charge itself...abi na perpetual motion machine?

tivta:
Like I said, this is a lifetime investment, what guarantee do you have that you would be able to afford changing the battery in 6 years? Remember the battery has 80 percent dod with 11000 recharge cycle. I understand if there is no money to buy it but as long as when can buy range Rover, throw parties etc we should be able to save for a pproduct that will guarantee power for at least 30 years. You even forgot to add the extra cost of charge controllers for the solar panels

This is not mixing old and new batteries together and that's d beauty of the string connection. In a series connection, u get higher voltage n higher efficiency from reduced loses due to low current flow however, a weak cell adversely affects the output of the bank. Parallel connection involves higher current n lower voltage hence more loses but the charging is better as each battery is exposed to same charging voltage. The series-parallel combine these unique advantages to give better overall performance. Even if you open the laptop battery, u'll see same series-parallel arrangement. In summary, the analogy I gave with d trailer tyres explains it all. He just need to make sure the old ones are in one string n d new ones in another string.

bigrovar:
with all due respect oga Dmerciful, nothing will kill is battery more. Mixing old (weak) batteries with new one is never advisable not with any connection string.. especially when it is a parallel connection. that is just a no no.

1- Parallel connection are to be avoiding even in the best of conditions its always better to thrive for higher voltage than then to achieve greater current via parallel connection. The problems lies with how hard it is to get the batteries in a parallel setup to having equal charge where you use a bus bar (more money) and ensure the wiring to the batteries are equal, since you can not determine internal resistance of each batteries.. one battery would still get more charge than the other. This would allow

1 the battery with least charge become a load on the stronger battery thus bringing the whole battery setup down.
2. Stronger battery gets over charged during the charging process has it gets full before the other battery in the setup. It will get over charged and over worked while the other batteries get undercharged. In the end the whole bank will fail in less time than estimated.

2. You are mixing strong battery with old one. and putting it in a parallel connection. It is just not the optimal and efficient way to go.

My advise would be that OP first do an audit of his consumption and load. The first thing u do before throwing money at a problem is find out actually what the problem is. In this case the problem is you want regular power. First thing is to do an energy audit. You will find out energy audit is the cheapest activity required when you take the step to solar or inverter.. it is the cheapest and the one that is most likely to save you the most money.

Calculate the load you want to put on your inverter, and how many hours you want them on per day.
e.g I want to have my tv on my inverter. My tv is 70w (you can read the tv power rating or better still buy a watt meter - less than 10k on konga -) and I need it to run for 10 hours

70 * 10 = 700wh

Fan 50w, runs for 10 hours = 500w

in total 700+500 = 1200wh.

in this example 1200wh is what you require from your system (this is just an example) from this figure you will determine how much battery you need.

if you are running a 24v system (which is more efficient.. higher the voltage more efficient) you will divide 1200 by 24

1200/24= 50

50AH is the amount u need. if that is all the load you require, then you can buy a 100 or 150AH battery. this would ensure that you daily use is between the recommended 50% or less depth of discharge to ensure your battery last long and allows you recoup your investment.

Doing an audit also allows you know how much panel u would require to keep your battery at full charge daily because it would make you know how much energy you need to produce to replace what is used everyday.

my 2 cents

Connect the old batteries in 1 string of 24v. Connect the new batteries in another string of 24v. Then parallel these 2 strings to have 24v, 400ah. Then connect to the inverter. This way the inverter charges them same time and saves you the extra work of manually switch to charge. Also because the new ones are stronger, they bear much of the load as it is more difficult for their terminal potential to drop due to load hence they do more work. They old ones won't load the new ones. Its just like a trailer with many tyres, the ones that are more inflated will carry more of the load. Only disadvantage is that it gives you false belief that you have 4 batteries when you have 2.7 batteries per se

obimind:
I have a 1.5kva inverter with 2 batteries rated at 200ah each. Presently my batteries are weak but still serves me for like 6 hours when fully charged. I intend buying two more batteries so that I can have two separate battery bank. Now this is my plan: I intend running the weak battery bank during the day time then run the new battery bank at nite. Now my problem is... Can I use one inverter to run the two battery banks separately? I'm trying to avoid a situation where the old battery will be acting as load to the new. Advice from kind hearted readers will be appreciated.

Still doesn't justifies the cost. How can you buy 1 battery of 12v 200ah for 700k? If you spend that money on buying more panels so that during the day ur ORDINARY deep cycle batteries is discharged 20% max...they will last for 6 years. Choosing what form of energy source to purchase also has cost consideration as a factor. You cannot use a tractor to clear a plot of land.

tivta:
It is a once in a lifetime expenditure, remember the cost of electricity will keep on increasing, I believe anyone who wants to be independent from public power will save to buy it instead of range Rover or parties...

Are you powering a street?

durodee:
I have 2. One with pwm 50amp and another with 60amp mppt.
I have a total of 4.5kw panels of Mono 1.53kw, poly 1.04kw and thin films 2.0kw. Five inverters of one 5kw, two 2.4kw, one 1.4kva and one 800va (my backup ), all pure sine wave. Two 60amp 24v external chargers. Three mppt CCs that are alive and well- one 60amp and two 30amp minus the hybrids.

@ Op...remaining small for you to call Dino Ipob elder

There are many factors that can affect this setup.
1. A 50w panel can produce 4A when its at its peak power. 4A will take 150/4 =25hrs to fully charge. Now consider you have about 7 hrs of sunlight and due to the variable angle of sunlight you get maximum of 60% averagely from the panel which is 2.4A. With this fact, it will take about 2.4Ax7hrs/day x 9days =150AH of steady sunlight charging for d battery to full.
2. It also depends on how you position the panel to get max sunlight.
3. You need a charge controller to regulate the charging and also give you visibility of what's going on,
In summary, you need to change your battery and get about 200w*2 solar panel and an mppt charge controller to effectively charge ur battery as even a new battery degrades within a short time if consistently undercharge. Since where you stay now has poor mains supply, u need effective solar charging.....cutting corners will be a waste of money.

BasedOnB:
Please help with this.

I have a basic inverter set up which i've been using for a
couple of years without hassles. My inverter is a falcon
series 800va 12v sukam inverter, and my current battery is
a 150 Ah 12v monilite ('Networking') battery. The battery
doesn't last for long anymore but i still get 3-4 hrs on the
average from it with my led tv/decoder combo after a full
charge (PHCN).

I recently moved to an area with non-existent PHCN supply,
and so i decided to incorporate a solar panel into the set up
to charge the battery. I got a 50W 12V panel and connected
it to the battery. The problem is the battery doesn't last long
@ all. I didn't use the battery for about 5 days in the hope of
getting a full charge. After 5 days, the battery didn't last for
2 hrs after loading my led tv (45W).

Right now, it doesn't even last long enough for me to charge my phone. It is that bad. Please what could be wrong?

The guy that sold the panel to me said i need to get a solar
charge controller to charge the battery, but i seriously doubt if it will have any effect whatsoever. I feel the battery isn't just getting enough energy from the 50W solar panel.

Is the solar panel too small for the battery? The inverter isn't a solar inverter, but i've been using it since 2012 without issues.

I would appreciate your responses please.

People worship a man that is just like them calling him father of their race! He was using tax payers/ND oil money to gallivant New York instead of touring is ceremonial kingdom. You voted for a tyrant who does not follow rule of law and now you want the oni who is not a judge to free ur thief but hold Dasuki....yeye dey smell.

Will soon be an illusion? Which planet are you living in? Which change? The one going from bad to worst?

Yes, he dresses well. I learnt he owns a popular media outfit that promotes fashion and styles.

I prefer this Kachukwu to run things at high levels to to some of these unknown for any laurels figures.

Buhari, please be guarded by excellence and performance in your appointment otherwise the much touted and awaited change will be an illusion.

All the best Mr Kachukwu!

This is not even federalism. Its a unitary system called federal system. There is no progress unless we change this system.

aariwa:
This federalism system of government is not working .Our people should be given an opportunity to vote in a referendum for a change from federalism to confederal system,so that we would have a weak Central government and strong states

If you choose to monitor it urself and have d time fine...but if left unmonitored and there power supply for a long time the battery can swell due to overcharging and the risk of explosion for sealed batteries is there.

durodee:
I think a fuller explanation will be of help. This type of charger is a bulk charger and has its use. I use it 4hours a day connected to a 24v 600amp setup with the rest of the charging done by my 1400w solar panels on 60amp MPPT CC.
To use that charger only or use it without good monitoring is extremely dangerous for you batteries. To leave your batteries empty /drained for long is also bad.
I will rather have this than nothing.

This is not a smart charger. It will ruin ur batteries!

viazi:
That's the charger!

missed fp by a whisker

There will be retribution and then restoration this northernisation policy by Bubu. Just a matter of time!

Bubu plans to destroy Nigeria knowingly or unknowingly. Just too dull to know.

Keep being surprised...who cares!

Tnycee:
I'm not pained bro....was just surprised at your response. Just surprised.

Truth is because you're not really attracted to d guy. If he is d kind of man u dream about, forget this story!

LuveU2:
Ive had to call it off with a guy after he tried giving me money immediately past our first date.

Firstly, its cheapening
Secondly, disrespectful and rude
Thirdly, it just shows i made a mistake dating a boy.

Well, as for the Op, sluts would always be sluts and they must live too.

Don't know the cost but most likely in Alaba you'll see it.

netotse:
Evening guys,

I'm wondering if anyone here knows the cost of the 'AC board' for the attached inverter. I've also attached a picture of the board.

I'd like to know the cost and location if possible.

Thanks.
