إذا كنت تفكر تشتري منظومة طاقة شمسية ليثيوم للبيت،
فانتبه...
أغلب الناس تقضي ساعات وهي تقارن الأسعار،
وتفاوض على الخصومات،
وتسأل عن عدد الألواح.
لكن السؤال الأهم الذي نادرا ما يُسأل:
هل البطارية التي ستشتريها
ستخدمك 10 سنوات أم ستبدأ مشاكلها بعد سنتين أو ثلاث؟
الفرق بين منظومة ناجحة
ومنظومة فاشلة غالبا يبدأ من البطارية.
أول نقطة أركز عليها دائما هي نوع الخلايا.
إذا كانت البطارية من نوع LiFePO4 فهذا يعتبر الخيار الأفضل للاستخدام المنزلي.
ليش؟
لأنها أكثر أمانا، وتتحمل درجات الحرارة بشكل أفضل،
وعمرها الافتراضي أطول بكثير مقارنة بأنواع الليثيوم الأخرى.
ثاني نقطة مهمة جدا وهي التوافق مع الإنفرتر.
كثير يشتري بطارية ممتازة ثم يكتشف أن التواصل بينها وبين الإنفرتر فيه مشاكل.
تأكد أن البطارية تدعم بروتوكولات الاتصال مثل CAN أو RS485 وأنها متوافقة مع الإنفرتر الذي عندك.
لأن نظام إدارة البطارية BMS لازم يكون قادر يتواصل مع الإنفرتر بشكل صحيح حتى تتم عملية الشحن والتفريغ بأمان وكفاءة.
ثالث نقطة لا تتجاهلها أبدا.
اسأل عن عدد دورات الشحن والتفريغ.
البطارية الجيدة اليوم تعطي أكثر من 6000 دورة.
هذا يعني سنوات طويلة من العمل قبل أن تبدأ السعة بالانخفاض بشكل ملحوظ.
أما إذا كانت الدورات قليلة فالسعر الرخيص الذي وفرته اليوم قد تدفع أضعافه لاحقا. أيضا انتبه لعمق التفريغ DoD.
البطاريات الممتازة تسمح لك باستخدام 80% إلى 90% من سعتها الحقيقية.
يعني إذا اشتريت بطارية 5 كيلووات ساعة فستستفيد من معظم طاقتها المخزنة فعليا.
ومن الأخطاء الشائعة أن البعض يشتري البطارية قبل أن يحسب احتياجه الحقيقي.
احسب استهلاك البيت أولا.
هل تحتاج 5 كيلووات ساعة؟
10 كيلووات ساعة؟
15 كيلووات ساعة؟
اختيار السعة الصحيحة يوفر عليك المال ويمنعك من الوقوع في مشكلة نقص الطاقة مستقبلا.
ولا تنس التأكد من وجود نظام BMS ذكي داخل البطارية.
هذا هو العقل الذي يحميها من الشحن الزائد والتفريغ العميق وارتفاع الحرارة وعدم توازن الخلايا.
وجود BMS قوي قد يكون الفارق بين بطارية تعيش سنوات طويلة وأخرى تتلف مبكرا. وأخيرا...
إذا وجدت بطارية LiFePO4،
بدورات تتجاوز 6000 دورة،
وعمق تفريغ 80% إلى 90%،
وتدعم CAN أو RS485،
وضمان حقيقي من 5 إلى 10 سنوات...
فأنت غالبا أمام بطارية تستحق أن تضع أموالك فيها.
Peter Obi took questions at the Africa Business Club Conference as well. It was a full session & he held his audience spellbound. You can see his obvious agility, gravitas, & sharpness. This is the type of 21st century president you need.
I tried a tweet I saw here about repelling mosquitoes by putting dried onion peels in a bowl of water in the corner of the room. Three nights later, not a single buzzing mercenary in sight.
What Our Pervasive Insecurity Requires: A Holistic not Reactive Approach.
In a hasty effort to be perceived as attentive and courageous, it is reported that President Bola Tinubu has approved the recruitment of about 1000 forest guards for Oyo State. This is a further demonstration of poor leadership and attending to very serious governance and security issues with a reactive approach. It is the same reactive approach that led to the sudden removal of fuel subsidy and floating of the Naira that has caused irreparable damage to ordinary Nigerians and the economy.
While recruiting more security personnel for Oyo state and the country is important, it should be done in a more organised and well-thought-out manner. Presently, almost all the 36 states in Nigeria are experiencing different forms of insecurity, with Oyo, Plateau, Kwara, Kogi, Borno, Katsina, Anambra, Niger, Imo, and Sokoto being very alarming.
The question, such as the reactive approach of our President, is whether all the states will receive the same approval to recruit 1000 forest guards per state, that is 37, 000 forest guards for the 36 states and Abuja or is the recruitment approval based on the mood of the President? Moreover, with the approval for Oyo, what will happen to the Amotekun Corps that is trying its best to secure South-West Nigeria?. Will they be disbanded in Oyo state?
The pervasive insecurity we currently have is directly related to the failure of our ecosystem, particularly leadership. It is only failure in leadership that can lead to the death of over 10,000 innocent Nigerians since 2023, and Nigeria is ranked among the top-most terror-affected countries in the world.
Addressing our insecurity situation requires a holistic or what can be described as an ecosystem approach. With failure in leadership, there is failure in unifying our dear nation, failure in industrialisation, failure in harnessing our abundant resources in agriculture, minerals, tourism, water, sports and even oil and gas to effectively generate required revenue, growth and particularly jobs for our exponentially growing youth population.
A New and Productive Nigeria will be POssible, and we will be OK! -P0

Also, let me know which ones you've ever tried.
As I promised earlier, here's another way to know if an iPhone is in perfect condition.
Go to the App Store.
Install an app called JCID Doctor.
Now, the job of this app is to help you test all the important functionalities of your iPhone, including microphone, torch, camera, etc.
When you launch the app, you'll see some buttons below the interface: "Auto" and "Manual."
For a quick diagnosis, just use the Auto option first. Click on "Start One-Click Detection." And it'll start testing each feature one by one. Follow any instruction that pops up.
When the Auto scan ends, note that it might skip some aspects because it'll be fast.
So, you'll do the remaining tests manually, by clicking on "Manual."
For the ones in blue, it means they've been checked and they're okay. The ones in white haven't been certified yet, so you'll click them one by one and follow the instructions that come up to make sure they're functioning well.
By doing this carefully, you'll be able to know if any part of the iPhone is malfunctioning.
Please let me know if you have any questions.
You can also share screenshots below in case you tried it on your current iPhone.
Stay sharp! 🪒
Tricks to make rent payments easier in Nigeria:
1.Think of annual rent as monthly rent.
If your rent is ₦1,000,000/year, think of it as ₦83,333/month.
Save ₦84,000 monthly in a money market fund, after one year your rent is ready with extra little cash
2.Let your ideal money pay your rent.
If your annual rent is ₦1,000,000 and you have idle money of about ₦12–₦13 million, don’t withdraw the rent from your money.
Invest the ₦12–₦13 million in Treasury Bills, money market funds, or other instruments yielding 16%–20% annually.
At a 16% return, ₦12.5 million can generate about ₦2 million in a year.
Instead of touching your money, you can use part of the investment income to pay your ₦1 million rent and still have some returns left over.
Be financially aware, please.
When you’re done quibbling over my choice of words, attempt to deny the veracity without proving yourself a plonker: Nigeria has been completely DESTROYED on Tinubu’s watch, and is now living on time and resources, borrowed from generations yet unborn..

The abduction of the Chibok girls in 2014 triggered a global movement. One school abduction was enough to unite Nigerians, attract international attention, and place enormous pressure on the government through the #BringBackOurGirls campaign.
Yet, what has happened since then should trouble every Nigerian.
Under President Buhari's eight years in office, Nigeria witnessed about ten school abductions. Under President Tinubu's administration, in just three years, we have already recorded over ten school abductions.
Despite these repeated tragedies, there has been neither sustained national outrage nor significant international attention comparable to what followed Chibok.
This raises an important question: have we become so accustomed to insecurity that what once shocked our national conscience is now treated as normal?
At a time when millions of Nigerians are grappling with insecurity, poverty, and hardship, it is deeply troubling that those in power appear more focused on political calculations and preparations for the next election than on addressing the urgent challenges confronting our people.
It is, therefore, no surprise that some observers have labelled us a "Now Disgraced Nation". While we do not agree with any attempt to define our great country by its present difficulties, we must acknowledge that persistent insecurity, economic hardship, and leadership failure have damaged our reputation and standing among nations.
The answer is not denial, propaganda, or political distraction. The answer is leadership that is competent, compassionate, accountable, and genuinely committed to the welfare and security of the Nigerian people.
The Nigerian youth must not become indifferent. We must all refuse to normalise failure.

Many iPhone vendors don’t know this, and those who know it won't tell you.
Before you buy any fairly used iPhone at all, there’s a hidden Apple diagnostics trick that can help you know if the phone is in good condition.
Here's how:
1. Switch off the iPhone completely.
2. Hold both Volume Up + Volume Down buttons simultaneously.
3. Plug your charger while still holding the volume buttons.
4. Wait a few seconds while still holding the buttons.
5. The diagnostics page should appear after a while.
From there, you can test things like battery, Face ID, camera, speakers, sensors, etc.
Some supposedly “clean” iPhones already have hidden hardware faults. This process can help you spot them before you pay.
You can also check this on an iPhone you're already using, so you can know if your phone is all right.
There's also an app that can help you do this.
Maybe I'll talk about it later in another post.
Circulate this video of Peter Obi’s address at the European Union across all platforms. Share it on WhatsApp groups! Let Nigerians see what it means to represent their country abroad.
Not Tinubu, whose every outing abroad brings us embarrassment and shame!✍️
Bro, I agree that election is science, but science is not entitlement.
A united opposition cannot mean Obi must automatically collapse his ambition into Atiku’s. If unity is the goal, then everyone should come to the table with respect, numbers, structure and humility, not with the assumption that one man must be VP because another man feels more entitled to the ticket.
Obi did not fragment the opposition. He exposed the weakness of an opposition that had no serious plan beyond “let Obi join us.” People with a clear path to victory don’t spend every day blaming those who walked away.
If they really know how to win, let them build, organize and sell their candidate. Blaming Obi for life is not strategy. It is emotional blackmail.
You can’t criticise Peter Obi without sounding dvmb.
Peter Obi doesn't like struggling, preferring 'Food is Ready' politics - Wike.
But Peter Obi rejected an assured VP ticket in PDP and chose to join a mushroom party to contest the 2023 elections alongside established parties like PDP and APC with his money.
He rejected possible ADC VP ticket and joined the NDC a new party to fight Tinubu and Atiku again
𝗜 𝗷𝗼𝗶𝗻𝗲𝗱 𝗣𝗲𝘁𝗲𝗿 𝗢𝗯𝗶’𝘀 2023 𝘁𝗶𝗰𝗸𝗲𝘁 𝗼𝘂𝘁 𝗼𝗳 𝘀𝘆𝗺𝗽𝗮𝘁𝗵𝘆, 𝘀𝗮𝘆𝘀 Datti 𝗕𝗮𝗯𝗮-𝗔𝗵𝗺𝗲𝗱.
But he lost his polling unit.
Peter Obi for me is just another Buhari...
- Sola Kuti.
But Buhari was not a billionaire; Buhari was never Chairman of banks or businesses.
Peter Obi runs away from fight but he has been a bone in the throat of the APC since 2022 without backing down.
Pastor Adeboye referred to me as "ABRAHAM," and when I asked what that meant, he replied, "Watch out, the Father of Nations." Bola Ahmed Tinubu.
Lmao 😂😂😂
RCCG go wan gaslight you 😂
