We Have Assemble Some Defensive Stocks As We Prepare For Offensive
Dividend paying/stocks with sone fundamentals are good as defence against the bears.

How do we play the defense as well

Omo I just dey check the site every second....

Thank God it's back

Give me a figure, if you laptop wattage is this it will last for this number of hours. With that I can make an estimate.

On a 45w laptop, you have about 5hrs backup.
On 65w laptop you have about 3hrs backup.

The good thing about it is you can use it for other light appliances.

freddie009:
How long would it last and what's the cost?

It depends on your laptop wattage.

Lesser wattage longer duration
Budget is less than 100k

sintolord:
I concur with you. For those who think Landlords who refuse solar panels on there roof are unreasonable should go to the market & find out how much it cost to roof the same house & imaging about 15% to 20% of the cost to fix the damaged sections of roof, then they will see & understand what the landlord see & understand.

Another option is to put down caution fee of about 500k or more Incase of any damage on the roof.

as we are blaming installers, lets remember some landlords no dey use better roof take roof their house,
if you are a seasoned installer you would understand where am driving at ( some dey manage wood self, i am always very careful about installing bigger wattage solar panel (above 450) because maneuverability require apt experience )

some aluminum roofing sheets are just too light, like i fit tear am as if i wan open biscuit nylon.

this caution fee don reach to rent new house
would landlord agree to refund if you keep to your own end of the bargain

I need a solar installer located in benin, and where can i get original jinko panels...anyone with a sure contact??

In case you don't find in benin, am in warri and am available

bassdow:
How do you know.

Speaking of professional, the meaning of that word "professional" has really been diluted.
Currently in talk with a landlord who's been replacing batteriies and upgrading one thing or the other. Met him recenty, have known him for over 2-yyears but since he's a distant neigbour (12-streets away), our interaction is just greeting, though I sometimes buy things from their shop.

Something happened recently that brought us a bit closer, but before then, while buying something from their shop, already asked the wife why they run their freezer on solar (since I could see 2 small panels on the roof), and would kill the battteries faster BUT she said No, that there are more panels at other side of the roof. I argued a bit but left it at that.

Later (probably 1-month later) I got to learn of issues from the husband because He's been battling solar wahala.
Asking him, He gladly told me the individual capacities of all the panels on his roof as 2pcs 150watts, and 2pcs 250watts and I was like wow. Did you install yourself and He said No, An installer bought and installed them, though they both went to the market to buy them.

I was like, what sort of installer is that that would do such rubbish job.

He said He heard from his wife that I know about solar, and that what I said about their solar seems true.

Further asking, i got to discover He has had to upgrade his inverter from 12-volts to 24-volts, upgrade his charge controller from PWM to MPPT. I was like wowww.

Further asking him while we were walking back since we met on the way, revealed that initially, he bought 1pcs brand new 200AH dryCell battery but when it became weak, he was adviced to buy another and add to it, so they bought a used 200Ah battery, and paired it in series to the already weak battery and again, I shouted in surprise, asking him Are you sure You are not the one who installed all these things to which hee asked would he lie to me.

So he begged I come next day to take a look and fix things. He somehow had faith in me despite not seeing anything i have done before. Just that, most things I said earlier without knowing anything about their setup was more than true + since I am like a ghost in my vicinity, people barely knows Me. if you don't see me passBy, you hardly would see me again till maybe I passBy aggain and e no dey pass greetings and I don waka.

Well next morning, I came and was just speechless. The charge controller of 140,000 naira was a used one with MPPT bolded written on it. it's very obvious it's been opened for repairs. it's equally obious it ain't MPPT.
Now the 2 batteries were 1 fake brand (alaba battery) and was bought brand new, the other was Ritar and was bought used.

i told him, even a secondary School student who ready physics knows you don't mix old and new battery, let alone this kind of nonesense.

At end of the day, made him realise the entire setuup was rubbish and the batteries would keep dying because the solar panels are too small to fully charge the batteriies.

When I told him the battery has never filled, he disagreed but when He asked the wife, She said battery bar indicator keeps moving till 7pm when there's no more sun and it stops. And I told him that confirms the batteires are never fully charged.

Later he called the person and put phone on speak annd asked how much he solld the second MPPT charge controller and the man said 145,000 naira. he said he was making recommendations to a friend and wanted him to hear the price himself.

Right now, the man is just speechless. They no longer uuse freezer on it. Just 1 Tv with 1 standing fan and some energy saving bulbs, yet as soon as the sun is out, the inverter doesnt take up to 2-hours to start making noise. the next it goes off.

Now the man is making plans to start all over again. Just this time around, he wouldn't go through them

na professionals dey like bear Engr.

HanisahZuwy:
Please nairalanders, patronize my younger sister. She has business with Monie Point. She's into the business of selling/registration of Monie Point POS machines. She sells the machines and also registers accounts. In case you or someone you know wants to have a Monie Point POS machine (s), or register/have an account with Monie Point, she can do that for you.

Please, I would appreciate if you can patronize her and also recommend her to people you know who might need these services.


Her location is Abuja, FCT. But, the machine can be sent to you anywhere you are, as soon the necessary registrations are done.

She also has a pickup point in Anambra state, for those in the Eastern part of the country.

For more enquiries, you can quote me.

Thanks!

how do i get a moniepoint ATM card

[quote author=keeper303 post=127386799][/quote]there will be no power at the output.
some inverters with display might on and display low battery...
different manufacturer different design....

This guy almost chew me raw 100%.

He say na youth

bassdow:
yea you're right.

What I meant is, it's way easier buying genuine leadAcid battery, than Lithium battery because at least we could seek with brand name, thhen go through the task of confirming thhe battery isn't repackaged.
For Lithium, we mostly are at mercy of the dealer. Not like we could go and buy a particular brand of lithium battery. Maybe if we start having established companies / brands who sells such, then would make it easier, else you're forced to rely on a dealer, who either hhave no track record, or don't mind much should their reputattion get soiled.

Even solar panel gan sef, a lot of people buy used PV as brand new. dem no know say most dealers get brand new stickers, all they need do is wash the solar panels thoroughly, then sort them accordingly.

Finally person Don break this table...

I was telling one of my Oga from this thread most New panels na. Chinko whey my brothers dey tidy..

I have installed a lot of them and I can tell you most of thrm are fragile just inspect the. Wire e get 1 company I no wan spoil their business

Yampotatocarrot:
Okay, thanks

If one has an inverter as a standalone, how will it be charged, or is it like car battery?

How do I know the watts of the appliances, laptops, phones, fan and bulbs?

you charge it using battery chargers via nepa/gen or you can adopt other means of charging such as wind etc

keeper303:
Please I also have a question. I have a solar setup of 2nos Luminous flooded batteries with 1600v 24v luminous inverter. The inverter is bad but I acquired another one but it is 1500v luminous. I wish to repair the bad 1600v 24v inverter and use it with 1 luminous battery. Will it work?

no you have to use 2 12v batteries to achieve the 24v

Yampotatocarrot:
Sorry my question might sound childish, but abeg I no know am

Is there a difference between using an inverter and the solar stuff, or do they come together?

Is it the inverter that determines how long the light lasts or the solar panels? Let's say one wants to use it in an office with just one ceiling fan and two sockets, for three laptops and, say 5 phones, how will one go about it?

Also, in an apartment with two sockets for one laptop and three phones at a time, how will it work?

In the apartment, will one need to get an electrician to rewire the house again, considering it's a rented apartment?

Thanks in advance to you and all that'll contribute

No worries you questions are permitted that's the only way we can keep pushing this thread.

To your question, yes you can have an inverter backup system without having a solar system (we basically refer to the solar panels as the solar system since it gives room to recharge the batteries without nepa or gen)

What the inverter does is convert the dc voltage from the battery to Ac voltage which appliances in the house uses.

You may need to provide the wattage of the appliances you want to run, it would aid the design of the system.

No there will be no need for an electrician.
The only time an electrician would be needed is for load separation and possibly point separation.

This tussle Don quench u wan come ignite am

Godfrey858:
My budget is around 700

To power those load you mentioned I don't think so 700k can get u a good 12v backup system

oweniwe:
Funny.

But the real reason I asked is cos I'm into phone charging biz using solar.

My PV array is very small and using inverter UPS and plugging so many chargers into the it is stressing the battery.

That's why I was wondering if there's a way I can open a charger and soldier wire from maybe charge controller to the chargers motherboard board and and it'll charge phones without hassles so I don't have to use inverter again

Cc: bassdow

U will need a special circuit to achieve this..

bassdow:
yea not small to charge the batteries, but powering the freezer [even] during the day, means the Solar panel is expected to provide a bulk of needed current hence my saying even the solar panels are small, irrespective of wether chargeController is PWM or MPPT.

You need consider loses both from chargeController, Inverter, Cables, even the panel sef might be overRated, + output of the solarr panels ain't often always at optimum levels.

trust me, those batteries no go last long because they would be overWorked like Nigerian private school teachers

Loses is always constant.
Batteries will do very fine if The quality is adequate

Please drop your contact number

Oh lie oh seas lie lie lie fine seas fine one.

I hope you can decode it.

bassdow:
me gan sef, seeing a 12volts system powering a Freezer is some how. Even if it works, you would overStress the batteries faster than necessary.
And the 2pcs of 345Watts solar panels sef is small.

I don't think 345w is small to charge the battery...
Like there is mppt controller.
Even on pwm, the panels will be adequate

isangjohnson:
If you have good installer in Benin, please let me know.
I designed a small 12v 160ah lifepo4 battery with 1.2kva 12v Tbb inverter, 80A Felicity Mppt CC and 2 pcs of 345w Jinko pv to power 120w freezer during the day and 45w LG tv, about 3 ceiling fans of 14w each and few lighting points (energy saving bulbs) at night for my friend.
The guy called two different installers and he was told the system will not power the stated loads.

Which side of benin are you.
I can handle the project for you.

Am in warri

isangjohnson:
10.5 Lvd is not bad 12v LFP battery bank.

Confirm if the battery can easily wake if it gets to that point

3kva gennex hybrid inverter for sale.
Price 270k negotiable ...
Location warri. Delta state

abcabc234:
u talk too much without making any meaninful impact... u do dis u do dat... are u more sound dan the manufactureres of hybrid inverters........

Boss small small.
Na him competence you dey question not his opinion .

dacool1:
Please electrical gurus, which should one factor when calculating how much back-up is needed,ie how long the batteries will operate, real power or apperent power of the loads?

Apparent power.
The apparent power puts into consideration the pf Which is always considered in energy transmission.

isangjohnson:
Please what is capacity of this inverter?
Does it have Lvd?
What is the idle power consumption?
I know it's 24v system and I want to use it with lifepo4 battery

LVD is 10.5.
It's not suitable for lithium battery.
Except your modify it externally.

You add a low battery cut off of the lithuim battery you want connect

bassdow:
says who.

I blame @Masterdazhem for openly stating his budget here. Hopefully, he doesn't end up using someOne here as installer/suppliier because chances that they would help him spend more than that budget is very high.

once again, I constantly would keep on saying this, make una try dey avoid Lithium batteries. Even banks, Telecommunication masts, etc, companies that have deep pockets don't/rarely use Lithium batteries, YET una for Nairaland go dey TRY force am down the throat of those who don't know any better. Some of whom are evven struggling to buy 200AH batttery sef.

I have 20 pcs of 300-watts panels, use both MorningStar, and epEver MPPT chargeControllers, yet na common acid battery I dey use and have encountered NO issue.

Also, make Una dey try dey avoid Hybrid Inverters. The way dem dey spoil eh, no be here. Even the process of REPAIRs get k-Leg.

That One paid more, doesn't necessarily mean they would get something much better.

I share this school of thought...

While we are shouting embrace new technology, you will be surprised that some military technology are still based on the old methods...
