Hi,

From my experience, here is the cheat code to the simplest and easiest technique to size a perfect off grid solar ess system.

1. Calculate on average how much energy you use daily eg 15kWh ie 15 units of grid (NEPA) light

2. Get a battery that is equal in capacity to your daily average energy consumption eg 14 - 15kWh

3. Then size with pv that is half or close to half the battery storage capacity eg 7 - 7.5kW panels

4. Then get an inverter that can carry the max total load power during your daily consumption cycle (ie what is the max power you use when all your needed devices are turned on).

So let’s assume with your major appliances turned on you consume a max of 3kW (maybe when microwaving food, boiling water etc). You then get an inverter that is minimum 1.3 x the max power, so in this case a minimum of 1.3 x 3kW power = 3.9kW. So a 4kW and above inverter is good.

Example: following the above, for a 15kW average daily total consumption, you will get a 14-15kWh battery, 7-7.5kW panels and a 4 - 5kW inverter.

If you size your system with this method, you will be 100 percent off grid and will have two (2) days of autonomy i.e if rain falls and there is poor yield, your battery will still last you the night of poor yield (2 nights if you add the night before poor yield day).

What if your load demand then increases?

It’s simple if divide the new average daily load by the former average load and multiply the answer by every part of you off grid system.

Eg, if you now consume average of 20kW daily

20kW (new) / 15kW (old) = 1.33

So 1.33 x 15kWh (former battery capacity) = 20kWh for new total battery capacity

1.33 x 7.5kW panels = 10kW for total pv

1.33 x 4kW inverter = 5.3 so lets say 5.5 - 6kW inverter

So 20kWh total battery, 10kW total pv and 5.5 - 6kW inverter is what you need you system rating to be in order to accommodate the new average daily load of 20kW.

Conclusion:

This is my personal, practical and researched method. Anytime you use it on the field or personally, remember, knowledge shared is the best reward for knowledge that was gained.

Bro,the bitter truth is that your wife has left you emotionally....

Bro, you can book deriy battery with 50 percent down payment and pick up the battery when it arrives Nigeria.... At no extra interest....i referred my friend and thats how he got it... Gave him more time to hustle the remaining money... Even the 40 batteries i want now... She say i just need to pay only 3 percent and should pay the rest when it arrives Nigeria...I don't think i will say no if somebody in Nigeria offers me something similar

Dear Sir,

Shipping terms for Lithium batteries have changed a lot since you may have last checked.

Now shippers can only load a container about 1/3rd full once it contains Lithium batteries and therefore rates skyrocketed.

Please reach out to me directly to close a deal.

THIS IS THE STORY HERE....

It was on 13 October 2000, when words went
round that General Muhammadu Buhari was
leading the Arewa team to the governor’s office
to confront the state over alleged killings of
Fulani cattle rearers in Saki, Oke Ogun Area of
the state. Buhari did actually telephone the
governor that he was leading a team to his
office.
In less than 30 minutes after the general
informed the governor of his visit, we noticed
that the entire secretariat was already filled with
lorry loads of our brothers from the North. This
created some tension but we kept our calm. At
about 2 p.m., Buhari arrived in a long convoy at
the governor’s office in company of the former
governor of Lagos State, General Buba Marwa,
Alhaji Aliko Muhammed, Alhaji Abdulrazak and
Alhaji Hassan. They all wore long faces. In
fact, the anger in them was palpable as all
pleasantries extended to them were ignored.
“This is trouble” was the expression on the
faces of all of us in the governor’s office.
Shortly afterwards, the state Director of State
Security Service (SSS) and Commissioner of
Police arrived. But their presence did not
change anything particular on the fears that had
already gripped majority of us. The two security
chiefs did not come with any operatives, they
came almost alone.
Late Lam Adesina Photo NAN
The meeting was called to order after Lam
walked into the Executive Chambers.
Introductions over, Buhari spoke on their
mission to the governor’s office. Emitting fire,
the general accused Lam and the government
of Oyo State of complicity in the killing of over
68 Fulani people in Oke Ogun area and
perversion of justice.
His words: “Your Excellency, our visit here is to
discuss with you and your government our
displeasure about the incident of clashes
between two peoples… the Fulani cattle rearers
and merchants are today being harassed ,
attacked and killed like in Saki. In the month of
May, 2000, 68 bodies of Fulani cattle rearers
were recovered and buried under the
supervision and protection from a team of
Mobile Police from Oyo State Command.
“ That some arrests were made by Oyo State
Police Command in the massacre with their
immediate release without court trial. This was
said to have been ordered by Oyo State
authorities and they were so released to their
amazement. The release of the arrested
suspects gave the clear impression that the
authorities are backing and protecting them to
continue the unjust and illegal killings of Fulani
cattle rearers…”

I just hope President Buhari is a "reformed Democrat",as he claims?

But his silence all this while, despite the repeated massacres, "speaks volumes"! I hope he is not still nursing the anger he had with Lam Adesina, up til today because they says "Fulani nor dey forgive or forget"!

stevedre:
How are yorubas big brothers to Igbo? Thats a hypothetical question so lets face the topic cuz same goes for the yorubas. The worse part is our parents had love for each other but we have gotten so bitter with each other to the extent we have not asked and answered a simple question, WHY DO WE HATE EACH OTHER AND WHAT DO WE STAND TO GAIN IN HATING EACH OTHER? My answer for both questions, NOTHING.
Tell me where i went wrong.

Bobo, se o ti se tan? If you no get better thing to do, go and fight for Enugu scaredy cats.

BakireBulmaker:
And what happened in Yorubaland?
Is it by any means comparable to the ibo massacre going on in the east?

totorimi:
Herdsmen indeed. How come government cannot take a stand on them just as they are want to do to Ipob. These are never Fulani herdsmen I suspect they are using that cover to infiltrate the nooks and cranny of our country to enable them unleash terror unlimited in the fullness of time.

Any community they invade must resist them with the full power they have because they are evil.

BeClever BeFOOLISH]
There is no different between their death and the death of all the IPOB members gunned down by the drunk military.
So as it is, I wish them all that you all have wished the IPOB peaceful protesters.

You know what you wished them then.. ....me I don't don't know, but whatever it were then, same to you now.. ..

I was discussing with a friend yesterday and we were going on about the spate of crime in Lagos, lamenting that things are taking a turn for the worse.
Then he began to tell me his experience with robbers who paid a visit to his compound at Ikeja last week. According to him, they seem to get smarter and smarter. They visited them with POS machines and moved from flat to flat, demanding you make transactions into their account at gunpoint. Once the transaction pulls through, they take your cards, record your pin and they are off to the next flat.

In this way, they drained virtually all the cash in his 3 accounts over the weekend.
Have you been a victim of this mode of crime, come in and share your experience.

Prec1ous:
I have an advice for all ill-spawned biafrans.

Why are you wasting time online constituting nuisance? That alone shows how myopic you all are towards your so-called promised land.

If you cannot bring something similar to the biblical plague of Moses, then get serious because you are stuck with Nigeria.

None of you all saying trash witnessed the civil and its not what you should be hoping for.

I prefer boko haram to you idiots, in there confused movement they can bite, you all are toothless bull mastiff. When one of you becomes a suicide bomber, we will know that you are serious.

Meanwhile...
-You can tear your Nigerian passport.
-Burn your Nigerian voters card and I'd card.
-LEAVE the west and North and March home.
-Destroy the Niger bridge and rename it.
-Tell your senators, honorables and ministers to leave there Nigerian duties and come home.
-Stop coming online to wail, go to Aso rock and cry there.

Declare yourself sovereign today if you are serious and stop nt is shady and foolish hypocrisy.

It hurts when I know it's the youth who are supposed to hold promise for tomorrow are the ones trading there life for a white elephant progress.

Anyone who quotes or mention me to say trash will have a short life span like the biafran dream.

Idiots.

Begonia:
Wait.

A mosque was burnt down.
No one died.
Someone apologizes to "the north"
"The north" is suddenly so mature for not retaliating.

Seriously?!

How does a mosque represent the north?
Are there not millions of Muslims from the south?
Are there not millions of Christians that are indigenous to the northern part of the country?

Am I the only one noticing that "northerners" are being commended for not retaliating violently.
Am I the only one noticing that they are being praised for not going on a murdering spree.
What does this imply?
A norm, a habit or some behavioural instinct?

Am I the only one that has noticed how sick of a country Nigeria is?
Am I the only one that has noticed how mentally damaged most of her citizens are?

It all makes me want to throw up.

Who doesn't know that Uwazuruike was compromised by the Nigerian government after he was detained and forced to sign an undertaking as a condition for his release.

Uwazuruike came back a compromised man and had since rendered MASSOB directionless, delaying the Biafran Independence.

.........................................................................................................................................................................

The FG wants Kanu to sign Same undertaking they got Uwazuruike to sign before they release him.

ccaramel: FG slams 70% duty on imported cars, 35% on buses
Wednesday, 20th November, 2013

The Federal Government has hiked the import duty payable on both new and fairly used vehicles to 70 per cent, SHIPS & PORTS DAILY can authoritatively reveal.
.........
On the other hand, as part of the policy, local auto manufacturers, like Innoson Vehicle Manufacturing Ltd, Nnewi; VON Automobile (formerly Volkswagen), Ojo; National Trucks Manufacturers, Kano; PAN Nigeria, Kaduna and other auto makers in the country, will no longer pay duties or levies on their Completely Knocked Down (CKD) sets imported from their overseas partners while Semi-Knocked Down (SKD) components for the local production of vehicles shall attract only five per cent duty without levy.
The memo explained that the new measures, coming about six weeks after the Federal Executive Council approved a far-reaching automotive industry development plan, were designed to boost activities in the industry and also attract foreign investments.
“The above measures are to create an environment to support existing assembly plants and attract other Original Equipment Manufacturers who have expressed interest in Nigeria”, the minister remarked.
