I mistakenly send 25k as airtime to my ODU line, and there is no option to buy odu data from airtel app, if you know a way out, please help me

I'm also interested. Happened to me once but I was lucky mine was 500 only. Still there.

amadika:
MTN is cooking something, I hope it comes soonest😀

If MTN introduces this ODU package hehehehe... Na speed of light I go use move 😁

Well, it all depends on the guy's financial capacity.....
But, I can assure you that out of 100 power banks and phones plugged, only 40% will be pulling the stated 25w, maybe 50% max, if you're in a student area where they use better phones and "better charger" cus you can have a device that supports fast charger, if you're using wrong cable or adaptor, max you'll be pulling is 10w.

If it's that 2kw inverter the guy can afford, let him go for it...I believe theres always a way to manage situations.

We're just giving suggestions based on experience, projections & what to expect. Of course the final decision is with him. He already stated a budget of 1.5m

Is there any way to set this G5F ODU to prioritize band selection based on network strength?

I noticed yesterday that it will continue to prioritize Band 7 even when it's down. I thought Nairaland was down for hours till I manually switched to Band 3 this morning.

AyobamiOluwole:
Now let’s do this maths you talked about a 22.5W charger charging for 1hour 40mins:

1hour 40minutes =1.67hours
Charging at 22.5Watts for 1.67hours =37.58Wh

Tell me which phone you’ve ever seen that has a capacity of 37.58Wh? If there is, it’s probably a gaming phone that is known only to gamers. Also, if a charger that is rated 22.5Watts will consume 37.58Wh (some energy are lost, I understand) to charge an 18.5Wh phone to about 95% to 100%, it means its efficiency is around 50%.

Most phones comes with Li-ion batteries of 5,000mah (5Ah just like these batteries Valto and Co sells 50Ah, 100Ah etc.) or 4,000mah (4Ah) with a nominal voltage of 3.7V. Meaning that for a big bank battery phone, it’s total capacity is :

5Ah by 3.7V = 18.5Wh
4Ah by 3.7V = 14.8 Wh

At the end, only 18.5Wh is the total consumption for big battery bank phone. So a 5000mah phone is 18.5Wh.

That a charger is rated 22.5Watts doesn’t mean it gives that continuous power rating, while some follow-come chargers are highly efficient to keep supplying the same rated power for some time (take a look at Samsung S23 below). Also, some phones don’t support fast charging, meaning that even if you buy all those inflated 😂 chargers, e no concern your phone. It will only take what it needs jejely.

Any phone charging business owner will do well to work with lower rated and efficient chargers that are designed to charge most phones without loosing so much power to losses.

You don't get the point bro.

2kva = 1.6kw because majority of inverters available have a power factor of 0.8

If the average rating of chargers is at 25w (x),(My powerbank charger is 150w), and number of phones & powerbanks (n), whenever n=100, x=2.5kw(+ or -) minus other loads. This will happen many times during the day.

With 4.2kva you're safe coz it's basically 3.5kw, which means you have more than enough room. Anything smaller, you must need to upgrade in a very short time coz your inverter will continue to shutdown many times due to overload.

As for total energy draw, that's a different case entirely dependent on solar yield and battery bank. Some chargers are smart and only pulls max rating between 1-80% & will continuously adjust based on temperature and other factors.

HIGHESTPOPORI:
I use oraimo 6 watts fast chargers for my phone charging

6 watts fast charger? Sure it's not a typo?

Fast charge starts from 18w, 22.5w PD and above( This will still take about 1hr 40 minutes to fully charge the average phone from 1%)

Even the cheapest power banks don't come with 6 watts.

The image below is the iPhone 5watts charger from so many years ago. These days they're only suitable for low power gadgets.

Where una dey see 15w chargers? Everybody just dey drop opinions lol.

The average chargers in the market right now are at least 25w, with some going as high as 40-50w power draw.

Phone charging business requires alot of energy, especially if you're located in a busy place that can do up to 100 phones and powerbanks in a day.

It's easy to throw words around like 2kva lol, try am first, body go tell u 😂. Better go and get a 4.2kva inverter if you're sure of 100 phones and above. That way nothing concern you with future upgrades. Don't be pennywise pound foolish.

WhiteAngels001:
Okay no problem.
Could you attach an estimated price for this set up?

Take Penuelseun suggestion above, as his advice is more practical if you want total dependence on solar. But in that case 1.5m won't be enough.

Go for a hybrid inverter 24v 4.2kva 330k

Get best Lithium battery deal from Mrreed 580k for 4.4kwh 24v

Get about 6 pieces of 550 or 600watts at least 700k (Panels are really big and heavy o so make sure you got roof space for it)

Budget better funds for installation and materials.

My reason for suggestion?

On load;
Assuming the average power of each charging brick is 25w, at full usage you're pulling over 2.5kw upwards that's why a 4.2kva inverter is suggested (Some chargers pull more)

Panels;
Your panels at full yield should be giving about 3.6kw, this means you will be able to fully utilize sunlight for daytime charging while getting your 4.4kwh battery filled by night time.

Battery size;
Assuming less loads in the evening, a 4.4kwh battery should carry you till 9pm with some juice left to begin the next day. Anything less won't give you optimal service and you may still need to use alternative source of electricity.

Note: A deep freezer's load isn't really significant as consumption is very low generally.

I want to appeal to all of us to try and be respectful to others here. You may not like someone's opinion, but definitely there's something to learn from it. To people that have questions, most of these questions have been answered in a few posts back, don't be lazy, try read up make we no dey litter thread.

@ bassdow permit me to use your method of long posts for once 😁

WhiteAngels001:
First of all, I appreciate your contributions on this platform honestly, I'm very confident that with people like you actively educating poorly informed ignoramuses like us on this subject matter of solar energy, we are bound to make a better buying decision.

Secondly, just like you rightly pointed, I don't have 100 phones to charge daily, however, I intend to set up a phone charging set up at very busy and central point where people come to charge for a fee, so I estimate that I might likely get I'll to 100 people coming to charge, but that may not necessarily be realistic, however, it's better to be over prepared than otherwise hence my statement.

Lastly, I have a couple of vendors trying so hard to sell me the cola solar 2000 as the best solution for carrying a 200l deep freezer and a phone/power bank charging station but having read many of the takes here, I felt very indifferent about the suggestion hence my question.

I apologize for asking the same questions that have probably been treated here when I wasn't active here, I just don't want to make any bad buying decisions. Kindly pardon my excesses.

I have someone running this business and he surpasses 120 phones and power banks in a day. So if your location is a busy one then be prepared.

The Cola Solar can't serve you if that's the case. You need a standard inverter at least 3.5kw or there about. Get a 4kwh battery, with enough solar panels you are good to go.

Litewriter:
Boss, what type of pot do you use, a name will be better, I have same induction cooker, using it with my haisic 1.5kva inverter, being using the following come pot..... I'm looking to get pots and kettle suitable with induction cooker.
Thanks

Steel and cast iron pots. Any pot that can magnet.

cyif2003:
Good day .. y does everyone seem to say a 12 volt system is not worth it. Inverter nd bayyery wise. Most people say minimum is a 24volt system.

On a 12v system there's less room for upgrades, why?

Because at 100A, your solar charging limit is not more than 1,200w. Which means if you plan to increase your battery size in the future, you'll be stuck at this limit thereby giving you the challenge of charging efficiently. This is why higher capacity 12v batteries are not popular.

At 24v, 100A is about 2400w. This will mostly be your charging limit too for most inverters, that is why above 10kwh batteries aren't popular for 24v systems.

So basically it's mostly about charging efficiently with available sunlight. But if you don't care about future upgrades, trust me, 12v is just perfect for your needs.

SourYoghurt:
to how many?

Which battery are you using? LiFePO4 can take up to 100A. But do 80A and check.

hoover420:
I use the Haisic 1.5kva inverter. I’ll check the manual once I close from work on how to increase it. Thanks

You're welcome.

You just need to press the down arrow 5 times to menu option 6, you should see the current max pv input current, press enter, the value should start blinking, use down arrow to increase till 80A, press enter and return.

SourYoghurt:
it's 60a

Increase it. Mind you, once battery is full it will cut down yield to match load on inverter.

hoover420:
Thing is I don’t even know how to increase the charging from the inverter and I hope increasing it won’t have effect on the inverter?
Battery size is just 3.6kwh

Which inverter do you use? Check the manual you should see how it's done. Pretty easy.

And no it won't have any effect on inverter. Lithium batteries can take up to 100A depending on the battery bms.

Gshems:
Well I have 2 535w and I get 650w before 10am it only reduces when my battery is full

Most people have their pv charging current set at probably 40A max that's the reason for low yield.

SourYoghurt:
I have 3x 550w jinko for my 12v 2kva inverter and on a regular charging I get 350w, I need to mention that I treat it like an egg, max load it takes is less than 150w, but I get up to 1.2kw input from the panels when I am blending during the day. I think some of these inverters behaves like ajebo when they don't have enough loads.

Increase your pv charging current for maximum yield. Probably stuck at 40A.

hoover420:
I got this particular panel and I thought it was just small panel till it got delivered. Infact I had to wait till everyone was out and in the evening before I installed because I know if the landlady see it, she might not accept to get it installed. Now the installer is telling me that I’ll need atleast 2 to allow my inverter to charge fast. I was like which kind wahala be this one. A 1.5kva inverter though.
Now my question is, can I get a lower panel like 200 watt to compliment it or I’ll have to buy that exact 535 watt bi facial panel again?
Meanwhile since I installed it 5 days ago, the highest it has produced is 250 watt and lower, I don’t know it it is due to the weather or that is the highest it would be generating

Check your inverter settings and increase charging current to about 80A (This should improve your output from panel)
Either way you still need extra same panel to charge efficiently.

What's your battery size?

Ebubemg:
Omo if u have the opportunity go for fiber, real unlimited

MTN fiberX?

williams85:
can you confirm the allocated data for the 3 months, let it no be the same for 1 month.

There's usually no allocated data till you hit 1Tb FUP. In this case I guess no one knows where the FUP applies yet, but my wild guess is still 1Tb.

Fremlin:
I'm installing it myself boss, so I understand

Be careful sha if it's on a roof top. And make sure to have like 2 extra hands for assistance.

Fremlin:
Just got the 725w jinko bifacial panel today...

It's too big, infact, it's over big.....


Installer fit fall why trying to bring them up to the roof

I think it's important people know how big and heavy these panels are especially if you're a tenant.

Even the 535w bifacial is so heavy omo.

AyobamiOluwole:
The way some of you say things with confidence, one begins to question their sanity. Lols BMS kor CMS ni.

He is correct. Your pack cannot function EFFICIENTLY if;
Batteries are of significantly different age
From different manufacturers.
Totally different bms.

That's why it's not recommended. Doesn't mean it won't work, but eventually to your own detriment.

AyobamiOluwole:
Has anyone ever run their Fridge on a modified sine wave satchet inverter before?

How was the experience? Is it advisable?


For more context:
It’s an LG REFRIGERATOR of 199Litres.

Not advisable

Gshems:
Is this true?

It's highly not recommended

People using alternative routers, do you get up to 50mbps? Asking coz I have an X25 pro lying around.

Meanwhile I experienced more network problems with the x25 pro when using unlimited 20mbps than I ever did with my ODU. So for me I doubt it will be really worth it.

All speed test results will be great yet streaming is still messy. Airtel and their magic 😂

fuckboys:
capped at 1tb each month or capped at 1tb in the whole 3 months duration?

Cos I'm thinking of doing it cos it's more value for money.

I don't trust Airtel enough. Not risking it 😂

morikee:
I'm 100% sure it will be capped at 1TB

Got same feeling

bassdow:
doubt there's any other recommendations better than what's been given above.

Once again, except you trust your Lithium battery sources, don't buy lithium. Lithium is better than leadAcid batteries e.g Tubular BUT fakes plenty for market. and knowing ORIGINALs ain't often easy for newbies; unlike Tubular / SLA batteries one could just tell you the brand to go for.

And going by those 2 quotations written on paper, na ordinary batteries + solar panels dem go give you.

Also you didn't state if your sister plans running any of the freezers overNight or at late hour.

Also if possible, make the battery 48v even if it means going for a smaller capacity one. Already gave you price range of both Lithium and Tubular batteries and those lithium batteries are from above average quality ones; not those cheap ones in the market.

if you could confirm the freezers runs overNight or late into the Night, we would know if to reduce the battery capacity.

Also, like I often tell people, don't buy any solar panel less than 300w and if buying brand new solar panels, ensure it's at least 450w or 500w / 550w and it's halfCut; not the old ordinary ones stiill be sold everywhere.

Give examples of fake lithium brands wey FULL market.

No other battery chemistry has more transparency compared to lithium as tests are abound and you can just choose from the available ones based on your budget.

For your 'quality' tubular brands can you point us to independent capacity test results to prove your claim? Or make we just 'trust me bro?'

adibo:
Good morning all. Just trying to get advice from those who are more experienced. I am currently able to use my 8kwh lithium battery from 100% in the evening to around 60/70% the next morning. After which, my panels charge the batteries back up and the cycle continues.

Is it OK if I continue using my lithium battery this way and just remain off grid? Cus I have not recharged my prepaid meter for about 2 days now, been using only the solar. My general loads are washing machine every few days, 120w fridge, 100w TV, fans and bulbs, 300w iron, induction cooker (used few times and mostly during the day and at lower wattage of 300w to 800w). I hardly exceed 300w/400w of continuous use.

I am asking because an installer was also advising that I keep on using nepa as the main source of light and keep the solar as back up for when there is no light, in order to preserve my inverter battery. So, what will you advise I do? Continue using nepa light as main and inverter as backup or I should just remain off grid since the inverter and battery can comfortably take everything in my house?

Enjoy your set up Chief. You have no need for Nepa except when Solar yield is poor and you can't charge your batteries full.
