I understand your frustrations, but a GOOD customer is always right. If you imbibed that philosophy, you would not have been impatient and not let the issue escalated. A simple explanation and apology would have sufficed. Next time if you don't have, tell him to source the cables somewhere else.

About your boy witnessing the measuring in front of him. My brother, in terms of business don't trust anyone, particularly a nigerian. Unless you did the measurements yourself, don't stick out your head for anybody. Those Alaba boys are magicians with both the tape rule and measuring scale. They would measure something in your front to be complete only to get home and measure it yourself and it becomes short.
Me, I have experienced it all.

I don't think Chichilas is lying or being unnecessary difficult, especially since this was the second time he is complaining on the same issue. He is genuinely upset.

Just apologise, make it up to him one way or the other. You could invite him for a drink or send him the money for a drink and forget the whole episode. It's just not worth the anger and bad feelings.

Chichilas:


It is not shocking. I said I would take this to the court of public opinion which is Nairaland because this is where I met you. You said I should do my worst. That nor be Nairaland Dey feed you. So why is it shocking you?

I am just getting started. You would be amazed how much time I would spend on your matter.

I also had the same question when I was still into solar power/alternative energy about a decade ago. It does not make sense to start with 12v DC, invert to 220v AC and then step down again to 12V DC using very expensive and sometimes fragile inverters. Why not connect the your 12v DC appliance directly to your battery or solar controller. I did a few experiments then and it worked perfectly. I bought a 12 TV and connected it directly to a 12 v battery and then connected the battery to a 200watts solar panel. (I didn't even use a solar controller). I was able to watch TV with DSTV when the sun was shining.
I didn't continue the experiments as I had numerous commitments that made me travel a lot.

Most electronic appliances like TV, Decoders, Laptops, sound systems, LED lights, etc eventually get stepped down to between 12 - 20vDC so a simple step up or step down converter would suffice.
When I have time, I will order for some bulk converters from alibaba.

I will only make comment on this issue once.

One thing I will tell you all is to pray against bad people that will disguise as friends in your life and drag you at the slightest opportunity. It's not everyone that's smiling at u that have good intentions towards u, when u r down their true intentions comes out.

This same person I have fixed his inverter for free, something that cost me over 70k (I spent that moni cos of padi padi) and he's claiming warranty on damaged MOSFETs.

I sent you cable twice yet you will say it's not complete. While going back and forth of it's complete and it's not complete, Next thing is you began threatening me on the fone and making foul statement like I can use 500k to fight for 50k, I will go on nairaland to go and ruin your reputation, I will arrange boiz to come and beat you. Who would have thought that someone I can close my eyes and spend 100k on if in distress without thinking twice will come and drag me that cable is not complete, such person will threaten to arrange boiz, such person will threaten to pull down my reputation.
You all better be careful with people that smile with you out there. They envy u in secret, one day their action will tell.
Calling me a thief and all sort of damaging things. He's saying them becos he knows I'm worth way more than all these things he's accusing me of.
Mr Reputation ruiner oya keep ruining.
I will also report this case to necessary authorities how you have threatened my life and peace. Should anything happen to me, they would hold you responsible.
You threatened anytime I come to benin you will arrange boiz to beat me up and all sort of things and also arrange for people to come and attack me in lagos. I will report all these things for posterity sake. Nothing must happen to me, you will be held responsible.

bassdow:


issue is, most of our so called Nigerian engineers, are only good at copying (verbatim) without improvements.

why invert 12-volts all the way to 240-Volts and above, only to have it steppEd down to as low as 6-volts or lower sef.

My 32-inch TV/Monitor is rated 20-volts, I run it directly on 12-volts. of course when you drop voltage, current would UP a little.

Before now, I have to open a TV, reWork it's power panel, and Create alternative port for lowVoltage which means a TV of 240-volts, would end up using less than 20-volts

Same with my Laptops, and Desktop PCs, my laptops are run directly on 12-Volts with no amplification from me.

Those that gets stuborn enough, I either tap the 12-volts directly from chargeController 12-Volts output (I tend to avoid taking directly from battery so as NOT to overDrain the battery when I'm not monitoring, and also to get clean supply, devoid of noise) OR I BOOST the 12-Volts to 19-Volts and supply it direcly to the laptop's power port and the lapTop would think it's receiving power directly from PHCN / NEPA / etc.


and I am not even an Elect/Elect graduate Ooo. I don't even have diploma in anything of such. Just childHood knowledge.

Hence reason I get disappointed when I see those who give themselves fancy names, with papers to back it up, not thinking out of the box.


All my Fans are tokunbo rechargeAble fans I bought for less than 7,000 naira at Arena in Oshodi, lagos and I removed all the converters inside it, and supply them 12-Volts direct.
those with weak Stands (since I bought them tokunbo), I convert them to wall-Fan, and I even have 2 rechargeAble ceiling Fans I converted sef and with that, I have no issues.

When I have very weak Solar-Battery, I don't just Dispose them off, I redeploy them to another position.
That's I have 3 sets of Solar panels - those that charges brand new solar batteries, those that I use for some other things, and those that charges weak / almost dead solar batteries.
Now those weak or dead solar batteries are the ones I use in powering all those FANs (I've got 9 presently), and (LED) Lights, made out of rechargeable Torch-Lights. I keep on using them till they're 150% useLess to me, then I look for those who buy them as scrap.

The only thing that really uses full light in my apartment is the chest-Freezer and I power than only during the day when the sun is out.

Even my outDoor Tv antena, I had to open it up, remove the transformer and resistor inside it, and replaced the Power-Cable with USB cable. Since the transformer is 6-volts output, I supply it either 6-volts or 5-volts from the USB port from back of my TV. Even my laptop USB port sef powers my outdoor TV antenna that has rotator. Only thing is - when I supply it 6-volts, when I press rotate button, it would rotate, BUT when I supply it 5-volts, it doesn't. well I rarely have reason to rotate it sef.

Now that's how far I have gone in converting things.


Imagine If I choose to open a shop, na to dey build UNIQUE power solutions, not all these followFollow things being sold everywhere

wirinet:


I go to Arena regularly, can you please link me up with where you get those fans? I need some urgently.

I am also not an engineer, I in fact studied architecture, but I have always been fascinated by electronics.

Incidentally, I was just discussing with my wife about the uselessness of our certificates this morning. Normally universities should be an ivory tower for looking for solutions to the countries problems, but Nigerian universities are just certificate awarding institutions with zero input on the countries technological and even social problems. Its only in Nigeria that you will find so many doctors and professors of engineering, but no single solution professed to solve basic engineering problems. What exactly they are professing is a mystery.
You that is not a professor and not even a master of electronics and electrical engineering can think of a simple solution to our power problems, but we have hundreds of professors and thousands of masters of electronics engineering and they are suffering the same power issues as every one else.

bassdow:


I don't care it's inBuilt battery is missing or bad or weak or even if the panel inside it is BURNT. I also don't care it's stand is broken - I go just transform am to wall-fan. in fact the more isues it has, the more I would cut more money out of the little I am willing to pay. na me know wetin I wan use am do.

Good day house. I currently have 300k to buy batteries for my CyberPower inverter.

Please I need guidance on the best type of battery to get for maximum benefits.

Load is a 200watts freezer, 1 tv, laptop, 2 fans, 3 bulbs.

samnaija:


If your budget is 300k for batteries, buy 2 tubular batteries. I am assuming the inverter is 24v. Nigeria hard whatever you have you manage. Note 12v system is not has efficient has 24v system.

Herdamorlar:

Thank you. I just want to power my tv, one ox fan and 5 5watt bulb.
I attached the pictures of the back of the tv and the fan. What advice will you give on this because I don't have much to get more batteries at this time though my plan is to increase the battery every 2months.
Also do I need to use solar controller when charging using only electricity can't from the inverter?

incogni2o:


Its likely due to.you using an.hybrid inverter.

A Blue Carbon battery I installed have also been drained about 3 times now.

I think its a bit lazy for the company to.allow the battery go so low before triggering it off

Inverter charges it via generator and it comes up back.

Get a non hybrid inverter to charge it.

its under warranty though, I could assist you how to return it to be checked

brightk:
Not all inverters have this function. But i think u can program this by using a user defined setting esp on hybrids. This is one thing abt lifepo4 customization. If i cant interact with the bms to allow for certain voltage disconnect then am not buying. Its either the inverter disconnects the battery from operating further or the bms can do that. Btw wat is the bsttery voltage?. Did u check the voltage @ the terminals to ascertain if there is still power across d terminals abi e don enter 0v

Buy a hybrid or transformer based inverter with a low voltage disconnect (lvd).
I have transformer based inverter with lvd that can work for lithium.
It's on the list on my advert but u won't see it.
U rather buy what u like and cause problems then come online to ask for solutions.

Obnoxious2001:


No Wahala..
Afraid dey hold some of us when we see price.. ..
Besides I already know the solution, however I was look for an already made system that can work independently with a preset voltage level.....

I was thinking of coming up with a simple analog comparator circuit, to notify the user when it has gotten to 24.5v

But enjoyment too sweet they fit ignore am, so I wanted a cutoff system instead of a notification system.

ojesymsym:
I read that the iPhone 15 has a feature that limits battery to just 80% to prolong the life of the battery. I thought this was bad practice years ago, has this changed? If so, can we adapt it to renewable energy?

bassdow:


it's HARDly efficient, charging a battery using an inverter. Often, I suggest getting an external charger. And for very large battery banks, it's even much more difficult, relying on the inverter, no matter how much you bought it inverter.

and now, it's much more efficient, and cheaper, kukuma getting solar panel(s) to handle the charging

brightk:
dat guy de use piple money de experiment. ..a bloody tif. Make e try am com post anything 4 here first. E nor go fit confront me 4 here sef.

bassdow:
Not just iPhones, but Laptops, and most devices using Lithium batteries.

They all have BMS, which helps you manage the battery. that your laptop says Battery low, does not mean you can't still run it a little more longer. BUT the BMS knows when to cut off to prolong battery life.

same when Battery temperature gets hot or too warm
