After years of experimentation at his workshop in the Cornish village of Callington, Jackson's eureka moment came when he developed a new formula for the electrolyte that was neither poisonous nor caustic.

'I've drunk it when demonstrating it to investors, so I can attest to the fact that it's harmless,' Jackson says.


I don't know why, but I don't take dailymail publication serious.

These guys are engineering the heck outta their harsh nature. We, in Nigeria, are still praying for good roads. WTF!

alphabbey1:
Just seeing this. My dear, up till now, I didn't see any alert. Have wisen up though. Anything I want to sell, no cash, no deal...

Glad you got some positive experience out of the ugly situation.

SolnergyPower:
BTW, how did you arrive at 35A @80%eff?

I guess since the 150w by 4 = 600w, at 80% efficiency, i.e 80% of 600w, we have 480w.

Given that the system is 12v, at bulk charging stage you should have around 14.2v for gel battery. Therefore using the Ohms law, current (I) = 480w÷14.2v = 33.80A which I guess got approximated to 35A

Edit: my bad, someone already answered it.

As if the APC is doing anything to take Nigeria out of the rot they are currently in. SMH! PDP failed Nigeria. APC is CURRENTLY FAILING Nigeria.

Topmost11:
Given the enclosed specs, can I connect the panel to the battery via the controller? I ask because battery is 12v, controller is 12/24v and panel is 18v. I know battery and controller are compatible but panel?
My question:

1.If a controller says 12v/24v, does it mean it can take voltages that are between 12 volts and 24volts(thus take 18volts) or it means it will only take either 12volts or 24volts. Thanks.

Picture is Panel specs and PWM controller(40a)specs.

The PV Vmp is 17.5v, you are good to go. Most PWM can take up to Vmp of 24v for a 12v battery system. The PV opencircuit voltage does not necessarily have to match 12v or 24v for either of the two.

I think say na only me!

Which would make the feat more remarkable!

Respect to him


But he looks older than 34 years ooo

Strenuous exercise gives you the appearance of an older person. Dude is super fit and possible not a day above his stated age. I congratulated myself for running less than a quarter of what he did under one hour. Lol.

charlsecy:
No. Bolt was a sprinter, not a marathoner.

What does the pacemaker do for him with regard to completing the feat?

For optimum performance on a long distance run in a flat terrain, each runner needs to follow their own optimum pace as opposed to a fluctuating pace. Randomly fluctuating pace consumes more energy for the same finish time. Keeping awareness of the current pace at any given point consumes mental energy which could be spent elsewhere. The relatively easiest method of sticking to a known pace is to follow a runner who is known or expected to concentrate on a specific pace known in advance

itzmoni:
Please look at my inverter and help me with any info please..new to this..would like to know if it was a good buy and how long it can go when fully charged.and loads i can put on it..thanks

Luminous is a good rugged Indian inverter. The only downside is the low charging current (~13 to 15A) which shouldn't be much of an issue since the battery you have is 150ah.

Sultty:
These police report brouhaha should be stopped nothing stops hospitals from saving lifes, haba so sad rip to d dead

I thought I read where the hospitals are told to treat gunshot and other victims wounded by robbers without requesting for the useless police report. Or is it only applicable for some states?

mcTrinity:
thanks Adrusa...

but the cable in question is still pure copper, but the flex copper (the type used in DC wiring).

the typical stranded copper (for AC wiring) is usually used for grounding... wondering if the flex copper cable can also be used.

You can use that. Just make sure you use the right size.

That's a paltry sum. Not that money could bring him back. But at least they should pay an amount that may help offset some bills and other things. Damn. This is beyond sad.

Thanks. It takes very nice pictures.

Demrich:
according to the picture above.... please give details.... inverter is 1.5/1.7, two 200ah quanta, epsolar 30a Mppt controller ? solar panels ? Cables other accessories ? As per this budget!

Heck, there's no way you can add solar panels and charge controller to the mix and the price will still be at 340k

Local man is selling

One of the best inverter out there. I envy the buyer

Topmost11:
Battery is about 6months old. I removed the battery reader and fixed the second battery reader to it and that one gave 100% and 13.1v. Presently TV and inverter are working now. When I fixed the battery reader to the old 100ah battery it read same 0% and 0.2v.

But what could have caused the anomalous reading.

It'll pay if you can get a portable clamp meter so you can successfully measure what's going on in your system. I'll recommend Uni-t clamp meters.

Beautiful pictures, abeg which camera did you use to shoot this? Awesome.

akpota:
boss mctfopt please post your number.

You can send me PM..

TechCapon:
but inverters are quite expensive. Unless a law is passed, police can't really force them to install the cctv.

No one can legally force hoteliers to install cctv, but if I have one I will install it to forestall spending so much in police. All you have to do is show police the footage and continue your business. Also, if criminals know you have one, they won't try to murder anyone in your hotel. The cost of the cctv will be paid if you do not have to shut down your business to enable our ineffective police to carry out "investigation" which will end with the owner coughing out large sums of money and losing money in the period the hotel will be shut down.

TechCapon:
is it hotels that are struggling to fuel generator that will install cctv?

There are cheap cctv that 60k can get one. You can always power these cctvs with inverter. That way you have something for the police in the event of a crime. If you cannot afford these, you are better off not running such business.

Topmost11:
So I should go for the 24v 2.5kva inverter rather than the 12v 1.5kva? Been thinking to go for the 12v 1.5kv

That will be better than a 12v system considering you plan on acquiring more panels since there is the need to add a refrigerator to the mix.

Topmost11:
Sorry for being banned. It happens.
My inverter is indeed 12v so I cant connect in series to avoid ending with 24v connection. My inverter capacity is 900v so it can't carry the fridge hence my quest for a new one.
If I ignore the "follow come" cc, then I can buy the 1.5kva (which is same 12v) connect to mppt cc to power my fridge and other appliances. I will buy one more 200ah battery and 4 more panels.
Then remove two mismatched panels, take this present inverter and pwm cc and mismatched panels and install for my mother. Two panels and 100ah battery is okay for my mum. She hardly watches TV, but needs power for light and phone charging

I'll recommend you get a 24v inverter system so you can push above 800w panel if you get your hands on a 60A MPPT Solar Charge Controller. 12v system heavily restricts you in the case of running any load greater than 100w. I always suggest you use a 12v system for extremely light loads especially bulbs and phone charging. To enable you run more solar panels you've got to think about getting off the 12v system.

Topmost11:
@mctfopt.
If I am correct, my present panels at 8a×4=32a in parallel has exceeds the capacity of the 50a pwm cc in it. And I still want to get 4 more panels. I am expecting a 60a mppt powermr cc. I know that will work with my present inverter but I am concerned about my fridge(inverter capacity can't carry fridge) Transformer in our area has been down for months now so fridge is redundant now.

Question is will the new inverter still need the mppt cc you talked about as it already has its own being hybrid? Thanks

You can use an external charge controller on a hybrid inverter. All you have to do is to ignore connecting the PV wires to the inverter's PV slot but rather connect it to the external charge controller's slot. I still don't understand why you should connect the 4 panels in parallel, are you running a 12v system while using a PWM charge controller? If your inverter's capacity is up to 1.5kva, it can handle most fridge in the market that is 200w or less. I was banned by the anti-spam bot yesterday in this section for reasons best known to it. I'm back.

It's all about the money for most of these "activists"

olaolu11:
Because its 24v, I am getting two 200ah batteries for a start and upgrade to 4 by year-end by God's grace.

I checked on the specs of the said inverter. I noticed it has a 50A PWM solar charge controller. I can only advice you try to match the solar panel's PV voltage to the battery voltage which for example about 17Vdc at max power for 12V systems or about 28Vdc for 24V systems.

You can always get another four 150w panels to increase capacity to 1200w. But left for me, I'll rather get an MPPT controller and connect all four arrays in series. Goodluck.

olaolu11:
Pls advice on this inverter.
1. How good is it?
2. Will it carry my fridge for about 4 hrs ?
3. I have 4 *150w panels presently, how many more 150 w panels do I buy?
4. The best configuration to connect the panels(all at joined in parallel presently)
Thanks

How many batteries do you plan to use and what is the capacity of the batteries?

durumibaka:
from the attached when battery is full the voltage is 3o.ov and when battery cable is removed from cc the voltage will be 34.8v.
my setup is 3oowatts×3, 2oa cc and 18ah×2 deep cycle battery, b4 installation at around 5 in d evening each panel gave us 34v or 35v but my problem is even at noon the voltage is not usually more than 3o.ov when the battery are full. please explaination for this?..

What do you mean by this "and when battery cable is removed from cc"? Why do you have to do this?
