Another one. We don't need a charge controller.We connect the panels directly to the battery

It is in her past. I have read enough stories of men including Police men who married former prostitutes and they got some of the most loyal wives one can ever ask for. Let sleeping dogs lie. I am sure when the time is right she will tell your brother herself. Be welcoming.

victorels:
If you understand how your car battery get charged while driving, you would see that the sun is a non entity in this case.

Thank you for your contribution. That is also another school of thought to discuss.

victorels:
What matters most is the size of the inverter capacity and the battery. You only need enough solar panel to charge the number of batteries.

But If I am an engineer, I will not need solar panel to install constant power as long as the inverter and batteries are available.

Unfortunately, I am not by paper qualification.

Thank you for contributing. I will add that to the list too.
The tariffs are scheduled to increase. How would you compensate for the higher bills to charge your inverter batteries? The sun is free. Just asking

I have been having some exciting exchanges with some experts in solar. We have been trying to determine how they calculate the size of the inverter, the battery bank and the size of the PV.
I have heard 4 batteries 4 panels.
I have heard inverters catch on fire
I have heard 3 kw in panels is too much for 4 batteries. (irrespective of the size)
I have heard you can't run AC on Solar
I have heard the system voltage has no bearing in calculating the battery bank or array size.
I have heard 4 200 AH batteries equal 800 AH. It does not matter if it is 12, 24 or 48 Volts.
I have heard panels are installed facing the east. (hint: the solstices and equinox)
I have heard I can installs panels under a tree or an obstruction.
I have heard. Solar does not work when it rains or when it is cloudy
I have heard solar does not carry Microwave or AC.
I have heard that PWM controllers work very well on huge installations.
We have seen 3 kw in panels with a 20 amp controller
I have heard we tell the customer the inverter size. If he wants to pump water, use his fridge, freezer, microwave and maybe run one AC 10 kva with 8 batteries.
What matters most is the size of the inverter capacity and the battery.
You only need enough solar panel to charge the number of batteries.


Please add your misconceptions and we will take them apart daily one topic at a time.
Solar will work better if we all understand how professionals arrive at calculations

Konnektions146:
check

Thank you

I have a current limiting device that doesn't allow my installations draw past the rated current and as well protect your inverters and then avoid heavy draw from your battery bank

Can you post a picture please

how is the fused connected to inverter

The fuse or breaker is between the inverter and the battery bank.

Importance of fuse and breakers. Today I plugged in an electrical kettle and our lights went out. The wires were warm to the touch and the fuse had burnt. The microwave and iron did not burn my fuse but the electrical kettle did. It drew the batteries from 26 V to 23 Volts. You can imagine the amp draw on the system.
Can you imagine what would have happened if I did not have the fuse between the batteries and the inverter? Fuses are cheap. Your life is way to valuable to risk your installation to an amateur.

The fluctuations in the level of power generation in Nigeria can no longer be justified by the activities of gas pipeline vandals.

We have the resources for continuous improved generation, distribution and transmission, coupled with the resource to secure them.

All we lack is sincerity of purpose.

The blue print to getting it right is everywhere and accessible, if we did not have one already.

Ghana enjoys constant power supply to a greater extent. What was it they had done to get it right? If not sincerity on the part of her government that knows where to draw the line of embezzlement of public fund and thwart the establishment of social infrastructure just to enrich themselves.

Here in Nigeria, corruption is pervasive. There is no go area, even in security of human life. SMH

Ghana has 12 hours on 24 hours off. Ghana is not an apt comparison.

Barezzi:
This is hogwash!
Tsmall, don't be straitjacketed. We'll do business soon...

What is a price quote based on? Have they seen where the installation will be done? Have they done a load analysis?

targus:
Hi,

Can you please give me a specs of what i will need to achieve up to 20 hours daily use of electricity using the following appliance

1) 1, Chest Freezer.
2) 1,Double doors American Fridge Freezer
3) 2,OX standing Fan.
4) 1, 50" LCD tv
5) 1, 1.5 Pumping Machine ( everything else can be switched off when using this)
6) 10 Energy saving bulbs. (Only at Nights)
7) 1 Dstv
1 Laptop

These are my requirements and ideally, i will like to not use generator for at least a whole day if there is power outage for multiple days.

please send this to

alex.adeyemi@targusgrp.com

Alex

Hello Alex how many hours a day do you intend to use each appliance.

iykmon:
[what is the best battery for inverter.

What are you looking to accomplish? 2 V 6 V are you best bets. Flooded is my first choice and an AGM my second.
Brands that I buy Trojan Hoppecke. I was told by my US distributor to look at Fullriver. If you have coins Rolls Surrette.

When did Geometric start to do work in Brazil. Lazy reporting or an attempt to deceive?

JUO:
Well I posted it for you to doubt. That was the main purpose of posting and I attached a picture for proof. Why don't you tell us 20a cc can't do more than 520w. Finally I have seen over 570w and 21a on my 20a cc

What is the system voltage? Remember that during the bulk and absorb stage your batteries will see over 29 volts. 29 * 20 = 580 watts. (assumption is based on 24 volts)

seyekan:
Pls house at what volt is a 24 volt system really full?

Look to the manual that came with the battery. The number varies depending on the battery

Nepa has been delivering between 98 and 287 volts. Our system continues to produce 230 v. This is why it pays to buy quality. There is no stabilizer in the house.

Sveen:
These racist sets of peeps, no wonder they're always at war, wicked refugee racists. Imagine their hostility, they are seeking help from other nations, yet they have the guts to racially discriminate the blacks; even in their dying times.

I am looking at the picture I don't see anyone getting pushed. He is too far away from the dinghy and is standing. The image is not representative of a person that was pushed.

Tough time for the banking sector. Emefiele is blocking most avenue of income making for banks : harmonization of CRR for both public and private fund, TSA, Near-elimination of ATM withdrawal charges, and the proposed COT reduction... thereby straining the earning powers of banks.


** There definitely will be massive lay out this year and next year....


** Aggressive deposit mobilisation and targets.

Bank could actually start to lend money to businesses. They have been going after the cheap and easy money. Those items don't grown the economy.

The government has played an out sized role in the economy of Nigeria. This has stifled growth and creativity on the part of our banks. The new regime's tightening of monetary policy and controlling liquidity is welcome. The private sector and not government should be the driver of growth.

Looks like very good quality work. Might be cheaper to do this than repaint our old car

I wrote a piece on LinkedIn titled quality vs price.

People always look at price first but in the long run that cheap item costs you three times more.

Happy reading.

Quality Vs Price; which matters more?

Thirteen years ago, I purchased a Mercedes Benz ML320. At the time it was a combination of the need to impress my clients and a flight to quality. I would still be driving the car today if not for an accident that forced the insurance company to declare it a total loss. It had about 250,000 miles on the odometer. It never left me stranded and outside of routine service it had no problems. I have been driving around in a 2007 Chevy Cobalt and the build quality is poor, the ownership experience is lacking and as an appliance it is not really that good. There are constant service and repair issues that need to be addressed. Trim pieces fall off every month, the steering rack might need to be replaced and the check engine light has a mind of it own.

We compete in a Nigerian solar market where no real standards have been established. Customers have yet to develop a strong brand following. In the Inverter market, you have brands manufactured by Chinese and Indian companies. The Europeans have yet to establish a foothold in the Nigerian market. The Chinese and Indian inverters hold a price advantage that appeals to most Nigerians. They can participate in solar or back up power at a fraction of the established market costs. The downside is equipment that does not perform. The chargers are grossly inadequate, they don't have enough cooling and the power and surge ratings on some are bogus.

The effect of poor quality inverters are:

Premature replacement of batteries
Inverters that trip when an inductive load is added to them.
Inverters that over heat, fail or catch on fire.
You saved money up front but you are buying expensive batteries every year and you risk burning down your house. Spend the money upfront. A good quality should have good cooling ability, a strong charger (60 amps+) ,very good surge ratings and a good warranty and support.

Spend the money upfront and get years of reliable trouble free from your inverters

A few days ago I put up a post saying that Lithium Phosphate or Lithium Ion batteries would be technology of choice in Nigeria within the next 24 months.
Even though your upfront cost might be higher you actual cost is lower. You can go below a 90% SOC. On your traditional batteries you are only allowed to go down to 50% if you don't want to ruin the batteries.
They have longer cycles. (number of time you can charge and discharge them) Up to 3000 vs 1200 for your regular sealed gel batteries.
We hope to have some to test before the end of the year and we will report our experiences to you.

Friends...a word of caution. 3 phase power supply in Nigeria is 380 to 415Vac but in North America it is 230Vac.

The equipment to be powered should be carefully examined and the right voltage applied to avert damages.

Bros in North America the voltage for three phase varies. For light industrial 120/208 and fother industrial applications 277/480. It is up to 600 volts for even larger applications. We very rarely see 230 v. Our central air conditioning and clothes dryers might run 240V.

dezo:
I have 3 phase air compressors i would like to power.Really didn't realise i would be getting 480v and not 230v. Maybe i would be better off getting the sukam colossal series 3 phase. Thanks

Your air compressors have three individual 230 V lines coming in? I got a call from someone telling me that all 3 phases in Nigeria are 230 each. My apologies

Then go do your research as local government generates revenue from it.

I did not argue with him. I have all the little certificates that they issued. It is not unique to Lagos.

dezo:
Hello house. is there anyone here that can connect 3 outback inverters to produce 3 phase? Please reply. Thanx

I have not done it yet. The instruction manuals that come with it are very easy to follow. Why do you want to connect three phase? Three phase in the US is 480 V not 220/230. Make sure that is what you are trying to accomplish
