The price tag is negotiable

With the amount of prayer coming out of Africa and especially Nigeria daily, it might just be that, that's what is kinda keeping us from this epidemic since our various governments have failed us.
Just imagine what will happen if this virus gets into Africa, especially Nigeria, especially in the north with high human population and poor health care and hygiene mixed with dry windy weather.
At this point all we can do is to hope and pray that this doesn't get into Africa especially Nigeria.
Our government, police, Boko Haram and Fulani herdsmen are enough epidemic, adding this virus will just be triple jeopardy.

I have a strong feeling that this virus is man made to control the rapidly growing population of the world and its depleting resources.


God help us all!

because of him today there is Amotekun in south west ,even if you dont like him but you can see through him the plans of hausa fulani people against southern people

Please, can you explain this your set up and the what's the total capacity
Explian better please

LifePO4 are still overrated, Expensive and complicated at the stage..

Until it becomes widely used that any inverter can charge it effectively like the Lead acid, till then

Just do proper sizing, Lead acid is more than sufficient at 30-50% DOD and complete charge.

Indeed 2020 will bring “interesting times” in the independent power economy of Nigeria. Note that the Chinese saying “may you live in interesting times”, is not meant as wish-you-well and easy fortune; it is a caution for preparedness and fortitude.

In the coming manna of LiFePO4, there will be hierarchy of quality and competency in the components, wiring, and software programming of the “energy storage systems” (ESS). LiFePO4 and other lithium based batteries are part of ESS, they are aspects of integrated systems; they are not stand-alone boxes that can just replace your existing lead-acid battery, kWh for kWh.

Beware the “affordable” lithium battery! These will likely flood Nigeria soon as they will be priced at or below ₦250,000 per 2.4kWh, attractive enough to compare with the ₦120,000 - ₦175,000 price points of the average-to-leading 12v 200ah lead-acid batteries. Many of these "drop-in, lead-acid-replacement" lithiums are sold in sealed enclosures , with battery management systems (BMS) that are either inadequate in their tolerance of variable current draw, high operating temperatures, frequent power surges and outages, or simply lack a means of communicating with external controls , or of reprogramming the BMS to suit the particular strengths or deficiencies of the intended battery charger .

How do you plan on managing the tight-margins on charge/discharge voltages demanded by lithium-based batteries or ambient operating temperatures above 35ºC in high humidity / high dust conditions?! In fact, you will likely need to ditch all you used to hold important for handling lead-acid-batteries, and throw away your lead-acid battery charger that claims to have a “lithium algorithm”, if you are to minimise expe₦sive lessons.

On the other hand, the price of lead-acid batteries should lower to more realistic levels. For years, the lead-acid battery mafia has managed to hold prices artificially high. That old game plan may change because the majority of the incoming LiFePO4, which will likely use grade B cells, zero warranties, and compromised BMSes to achieve affordable prices, may yet still deliver superior performance per kWh to compare with the over-rated AGMs or the finicky Gels, or the space-hugging FLAs.

But, please, don’t believe in “LiFePO4 can deliver over 3000 daily cycles at 100% DOD”!

ojeysky:
Thanks I didn't even pay close attention to the voltage..... that's at least 3x300w. I guess DC pump is not yet an option for borehole then

ojeysky:
Anyone using this kind of DC pumping machine? I like to specifically know if it's a worthwhile investment or whether going the normal AC pumping is better

NiyiOmoIyunade:
The tubes might be a more efficient energy transfer mechanism than a DC element immersed in water.

I believe solar shop in Lagos VI have the kind of water heater you seek where PV panels provide power to a DC element which then transfers its heat into the water.

I use a 300L Ariston with the panels and tube attached to the tank.

Its airborne does not mean the virus is floating in the air around us.

The carrier can cough around u and it will be transmitted through the air

motionarena:
Good step by the Chinese government.

If it where to Nigeria we will be extinct by now. Someone will know he/she is infected and will still go to the market and enter public transport.

Thats how i contacted chicken pox during my IT.
I boarded molue as i turned my head, I saw the guy sitting next to me with pox and powder over his face.

I codedly left his side but it was too late i was already infected.

Had to stay home for two weeks.

NICKEL IRON BATTERIES!

Good day forumites ,

Who knows about Nickel iron batteries or why not really in use down here esp for solar application. I hear a lot about lithiums but some don't know nickel iom is one of the best batteries ever. Beats Lithium Ion by 200% designed by Thomas Edison !

It's basically one of the cheapest batteries per kwh cost. Minimum lifespan is 30+. The first one built by him is still working AFTER 100 years "see snapshot below"

It's mostly used in the oil and gas industry here in Nigeria. They are flooded but the electrolyte are replaced every 10 years but only 1% capacity is lost after that 10yrs. . Simple charge profile just like lead-acid unlike the BMS profile for lithium iron . It also works in very harsh temperature from as low as -30° to as high as 90°C . Mind you, the cost is cheaper than lithium Ion battery.

The only reason why it's not being sold is because of







YOU, ME & THE POWER CABALS.

We no go chop again.
100 years? Nooooo

ICraft:
I believe your Battery is Lithium ion Phosphate (LifePO4). your max voltage per cell is considerably lower, about 3.6v per cell. I use Lithium Ion. Max charge voltage per cell is 4.2v. I set my BMS to shut down Charging once any cell pack reaches that set voltage (4.1v). I don't do float charge

ojeysky:
I agree that putting the lithium consistently at 100% DOD will certainly affect life span in the long run (just as doing 50% lead will as well). However the intention was to give a capacity equivalent else I will actually say the better DOD spot for a lead acid will be 20/30% while that of lithium is good at 70/80%. That way the lead acid may be able to survive up to 75% life span of a lithium. It still won't last the years of a good lithium but should be close.

That said, am curious at your lithium voltage figures, do you mean your batteries actually hold voltage at 4.1v? As that seem like a max charge voltage to me (though I don't even get the high in my case).

ojeysky:
Folks if you can, go lithium FP mine has been throwing great performance thus far!

Blindersoff:
Yes o and Jonathan led us to recession and thus the devaluing of the naira. Thank God for Buhari sha

Trex4:
sarakki tell me the truth. Why all of a sudden you started critizing Buhari?

adrusa:
Below is a schematic I pulled from the internet. The contactor is wired as shown. The two switches, red and green are the two switches that control the contactor. When they are both on, the contactor closes and supply power to the pump. To use it for float switch or as a switch, you keep one of the two switches closed by connecting the terminals together without a switch in-between. Then you connect the float switch (or any other switch) to the second switch. When your tank is full, it pushes up your float switch and makes it horizontal. This will disconnect the contact in the float switch and switch off the contactor. When the float switch drops and becomes vertical, the contacts will be made and switch on your pump. I actually leave the other switch connected so that I can turn off the contactor/pump whenever I wish. If you don't connect the second switch, you will have no control over the pump, only the float switch will do the control.

HETER LIFEPO4 BATTERY NEEDED

THE 480WH MODEL

WITH OR WITHOUT CHARGER

JUO:
please note 0.5hp ac sumo is 700w. Just get 24/36v dc sumo, consumption is around 200-320w. Your best bet is 24v/200-320w, you can parallel 2pcs of 24v/200w to achieve this, no inverter, battery, controller is needed. Just avoid ac pump. This option is cheaper
