CountinBlessins:
If this happens that means power supply bout to go super crazy

if you pump 50,000MW, Nigeria will still lack electricity

What do you mean by good hotel?
What will stop me from getting the return of my investment in bad hotel?

in a good hotel you can raise the rates higher, 500 naira per Kwh sef is nothing. they have customers that cannot stay one second without AC... And thats premium if you ask me... Plenty hotels nowadays they only on gen in the evening... Upon say e cost...

jonescosmos:
Nope.
It's because the solar panel energy is oversized and the Grid has been made the last option to draw energy from.
So the inverter draws as much power as possible from the panels, Charges Battery if the SOC is less than 60%, Powers up the smartLaod interface which is where Water heaters and ACs are connected. With one ACs connected to the UPS Load interface.
If at night time and the battery SOC drops to 40%, the SmartLaod Interface shuts off, and if the Battery SOC drops further to 20% and the sun is not up, Grid interface is turned on to handle the energy demands till sun up.
Take a look at the attached picture. It's 10Am and am grabbed more than 6Kw from the panels already.
It goes up to like 15kw sometimes.

you suppose buy one electric vehicle de dump energy i tell you.

isangjohnson:
6 people.
500w max during the day and 300w max at night.

you go need like 60KWH battery to comfortably run a full day without nepa or sunshine.

Oga TechGeek777,
Please come and do this business analysis for us.
If 9m is used for the installation, how long will It take us to get our money back at the selling rate of #200 per kWh?

what size of system can you achieve with 9million first of all... Only battery don finish that money o

isangjohnson:
I was equally working on the cost of installation, considering the high cost of materials and how long it would take to get back the invested cash.
Many of us are looking for short term business.

lol, if its in a good hotel you can get your money back very quick....

isangjohnson:
Please contact me via my mobile phone Sir.

i have replied your email check your inbox

jonescosmos:
I get light but my inverter simply ignores it. Take a look at the attached picture.

but wait, is it because of the low voltage that happened days back?

durodee:
I am entranced. Do you happen to have a rough idea of the cost of the prepaid meter?

https://smartechpower.com/product-centre/
This link takes you to his website, all his products are listed there with prices

isangjohnson:
Thanks for this information. We're progressing...

i have one engineer for all these things sha... Even if you want prepaid water meter and gas meter him de do. Bilaad estate abuja na central cooking gas de feed all the houses,, just recharge and use... Even the central generator no be flat fee, prepaid meter too.

jonescosmos:

this your power plant wey suppose de supply the grid.

Obnoxious2001:
Where did you get this from

website of Nigeria ministry of power, they update every 24 hours

jonescosmos:
It's only them that knows where they sent 99,299.89MWh to oo.
Perhaps they can break it down further to show how many Mega Watts that was sent to each states. And let the states confirm the numbers.

lol, u get light abi you no get light? This days if you see 12 hours na thanks giving

ojesymsym:
Any literature to point me to, to learn more about this?

https://developer.flutterwave.com/docs/making-payments/bill-payments/


Its just to copy the API of end point payment from Flutterwave to your website, then the software vends the code after a successful payment transaction.

ojesymsym:
Are these meter able to integrate directly with flutterwave so that each payment automatically updates the meter? I would love to know how this works

yes, there is an administrator software for PC for all configurations.

if you love numbers like me....the Nigerian national grid performance for wednesday and friday ....

isangjohnson:
What type of prepaid meter is he using?
For power draw limit, I guess he's allocating current limiter switch to each room.

oh there are simple single phase pre paid meters{lots of chinese made to choose from} that are available for sale in the nigerian markets,that you can connect to a payment platform like flutterwave, and you get credited as a landlord each time the tenants buy units....as for power management, that one is a very easy and cheap to solve, just use a smart circuit breaker ,one for each room, set power limit from the app, and you will be notified over the internet each time the tenant crosses the threshold. i attached a screenshot from the one i am using.

isangjohnson:
Na this one I dey generate and waste my power daily in Uyo.

lol, u for de sell energy give your neighbour(s).

FEGEITOK:
Interesting idea.

BUT

150 watts is too small. It should be a minimum of 1000 watts per room.

As a person who visits Akwa Ibom frequently, I understand just how poor the power situation there is. As limited as the power he delivers is, he is a godsend to those students.

I knew how frustrating it was to be a student without electricity and I had up to 2 generators at a point, and to guarantee constant light, I sometimes never stopped the gen even to refuel (as risky as that was I will admit). I recall how after the generator would run non-stop between 3 and 5 days the sound would change, then I would have to put it off so it could rest to continue the battle later.

Thanks for sharing.

1000 watts per room would baloon the budget for the project without joy, but also the student will be charged very high per unit. And they will abuse it, Electric iron, electric cooker... Washing machine... His inverters will work extra and his battery will bleed. Currently at 60 rooms the maximum draw from the students will be 9KW (9000 watts)..,and i think he using two units of 10kva each inverter for everything. At 1000 watts per room, without surge the peak consumption will be 60KW...its not like he cannot do it o.... But e no go hostel again o... Na to call am apartments o... And u know how much apartment de charge per day. E choke. Dis one na make dem just charge phone, on light, plug laptop and sleep with fan.

FEGEITOK:
I agree with you, the next deal I close and get paid for, I must upgrade my capacity in PV and batteries to 12kW.

Here in Abuja, their 18 to 20 hours of electricity is no more due to sabotage.

Seriously, do people sell solar energy in estates now? And at that rate?

it depends, my friend has a private student hostel in Uyo, generator is banned, he installed solar and installed prepaid meter in every room...When we last spoke he was selling at about 200 naira per kwh.. And you can't draw more than 150 watts at once,the guy no de ever get vacant room..... But at the moment, i am discussing with another company to come and do the same for me in UNN nsukka for a private student hostel, meanwhile the same company have given me there rate, its 100 naira from 8am to 4pm (when its sunny), and 158 naira from 4pm to 8am the next day.

FEGEITOK:
Clearly the distribution companies do not want to miss any part of the latest cake being cooked by the current administration

am telling you, its unfortunate that disneyland have there own twin 75MW solar power plant, totalling 150MW , abuja, kogi, nassarwa and niger state de share 469 MW, [ average is 117MW per state]....na only solar fit save us quickly... I have done the maths, if you are using 1kva generator, (i pass my neighbour)... With the current price of fuel, it will cost 700 naira minimum to consume 1 unit of electricity...yet some people are selling solar energy for 150 to 250 naira per unit in some estates... Pennywise if you ask me.

i knew it will come to this eventually, ....in the afternoon they will just turn off thermal energy source and switch to solar.

If you pay your taxes do you need to go to parallel market?

DEXTROVERT:
This
Will result to
Policy summersault

Many
Will
Now
Run
To
Parallel market

So
As
The
Demand for parallel dollar increase
The price goes up.

It would have been better
To divert parallel market customers to bank
Where they get dollars at official rate.
So few will patronize them

For example, with POS everywhere, we don't go to ATM or quene at banks to withdraw money.

Obnoxious2001:
Do you buy already made controllers or you design from scratch

controller ke, there are ready to use systems o, on the low side we have tuya and ewelink products, on the high side control 4, crestron, savant.

Watianoengineer:
Glo remains the best Nigeria. Their berekete bonus is massive and their airtime bonus calls all networks. I have been using Glo for 20years and I have no regrets.

dem no gree sell 45gb/6k

tivta:
whats your view on felicity lithium batteries

to be honest, its as good as it costs... Anything that will perform more than it on the same rating must cost minimum times two of felicity... Na only this battery from BYD i fit suggest for person wey sabi brutalise and abuse Electricity and I will go and sleep. I have worked in two houses in abuja that uses it, and they are both electricity brutalists... To give you an insight, one of them is a four bedroom with two units of 4 Ton central AC... Then 5 units of 1.5 HP individual split AC... There is a swimming pool machine...washing machine, bore hole... The list goes on... Maximum load is about 35kw in that house...the full battery bank is about 120Kwh (8 units).... Yet...its been Over two years and the man no de slow down... You can't abuse felicity like that..... If you want to enjoy felicity, just take am jeje.. For example, you see that 15kwh battery from felicity , I always tell people never to draw more than 3kw at once.

Obnoxious2001:
Na to come learn work engineer

omo, everything de YouTube this days i no go lie....but na the zeal to do breaking, do piping, climb ladder... Run wire... Crimp wire...etc be the main koko.

FEGEITOK:
R=

You seem to know a lot of what is happening.

Saw your project. Are you an end user or an installer?

am a smart home engineer... So we mix with renewable everyday, plus I have a small setup of my own.

only 20 sold, not impressed. try another vendor

jidobaba:
Good deal fellas?

funny thing is that, in europe and US, people install solar to get electricity cheaper on the long run as electricity bills continue to surge, now in most cases, electricity is cheap at night(when your battery makes sense as no sunshine)...people have been programmed to use hybrids to do more tasks in the afternoon with solar power direct and manage the battery till midnight when cheap rate kick in that will last in some cases 4 to 6 hours max..in nigeria now,the next subsidy to go is electricity subsidy, the minister have already said that the plan is 3 years from now...and then nigeria will see cost reflective tarriffs...i am predicting 350 to 500 naira minimum per unit...na only HYBRID fit save person by then sha,unless you wan de run into your expensive lithium lifespan...

jonescosmos:
I am unapologetically a hybrid fan, till next life, Take it or leave it, standalone systems are gradually becoming obsolete.

Deye and Sunsynk and a few other brands are taking the lead. Their inbuilt MPPT are the best so far, they will suck the juice out of your panels before considering any other source.
The configurable Gen-Port option makes it possible to have your heavy loads turned off and on according to the battery SOC and available energy from the Sun.
Configurable "Time of Use" makes it possible to tell the inverter when to use Grid to charge your battery.
Configurable Protections from unsafe Grid sources are the bomb. For example you can set the inverter to ignore grid if the incoming Ac voltage is not within 200V and 230V. You can also tell it to wait for some time (say 1-5minutes) before accepting grid when "Nepa brings light".

We now have Hybrids with 1000HVDC (High Voltage DC Input) both on battery Input and PV inputs, meaning that they do little or no energy conversion or inversion on the DC circuits. Say you have battery banks of 1000VDC that can charge with 200-1000VDC source, and PV array of 800-1000VDC, so your HV Hybrid Inverter just passes the Voltage to the battery terminals without worrying itself. Blue Carbon has such function where you connect the PV directly to the Battery, Oh yes you heard me right. No external CC or Hybrid required because the MPPT is built into the Battery.
Many of these functions are not yet available on the Voltronic based Inverters.
People should not be discouraged from getting Hybrids, rather you point out the functions and safety features to look out for when considering a Hybrid Inverter.
To Prospective Hybrid users: Do a good Earthing, Get a good Stabilizer is possible, Check out the interesting features of the Hybrid Inverter you are about to buy. If all pans out, go for it.
Truth is, Hybrids are here to stay.
Please let's stop instigating fear into people who are contemplating on startups with smart systems.
