The bolded is what I was also suggesting, just didn't want to mention a specific brand.

Industrial stabs also are able to help in these regards.

GloriousGbola:
most premium devices can withstand fluctuating voltages. however a voltage leakage usually means that there will be voltage across your neutral. this means you may find that instead of 230v, you can have 300v or more between your live and neutral.

and that will blow your equipment. when you have a voltage leakage, usually because of a live supply coming in contact with a neutral or earth wire, the rccb / elcb trips.

i ave no faith in most of the stabilizers sold here. they are mostly only for 5-10% voltage fluctuation. if you really want a stabilizer, get a a PRAG and connect across your mains

the other thing you do to protet your electronics is a lighnting arrester - but that should be as far from your main building as possible as it can induce surges while delivering the current to ground. also for me, it should be completely seperate from the rest f your earthing as any fault can lead to the current traveling back into your system

Village people just use this neighbor. Bad charger with a faulty component most likely but why not just bring out smoke rather than destroy something else? Strange

As to your final question, I leave that for my opponents to answer.

FEGEITOK:


No contest.

However ever since one bad experience I am extremely worried about connecting poor quality equipment to my electrical circuits.

I was enjoying listening to music on my high end audio amplifier worth thousands of dollars. I was the only one who had power. My neighbor knocked and begged me to help charge her phone. The moment I connected that phone charger to the same outlet as my amplifier, my amplifier went bad. A post mortem indicated that one of the channels died.

Since then I am worried about the quality of the equipment connected to my outlets.

So while RCCBs protect against shock, I imagined all the worst things that can happen if I bought a fake RCCB.

That was why I had to be personally involved in buying the RCCB.

Might have been a coincidence but until then why didn't the amplifier fail?

Left channel is on its own. Right channel is on its own. Right channel power transistors died. If I remember correctly even a diode died. Those things aren't in Nigeria. I had to import replacements.

Left channel was still working.

But I wanted my equipment whole.

I was running off a generator at the time.

It was one of those poorly made mass market Chinese phone chargers.

If I disconnected the power supply to the right channel, the left would work.

The terms you guys use. The more I stay to read and understand the more I get confused. It seems like every device has more than 10 different names it can be identified with.

They are using animal language

For example the recent ones PRAG, RCCB. Seriously whenever I think I'm beginning to get it and I see an analysis I get even more confused.

isangjohnson:

Technical language. It's confusing. I'd see a question on what someone needs. I will imagine the setup in my head even though imperfect, but when the real responses start coming I get lost in the terms. I already saved the advice I got for the setup I'm working on but whenever I try to grasp some new analysis I get lost in the terms.

Sapiosexuality:

PRAG is a company that makes electrical equipment.

For RCCB, see post below

FEGEITOK:

My point was that if I bought an RCCB of doubtful provenance, then not only is there a risk of shock, but to my mind, my equipment is at risk.

Now, I am not under the impression that I need to save some cash to make extra profit, that is what some artisans would do. Neither am I willing to engage some heavy height electrical engineer for this to my mind very small project - the engineer will most likely use the proper RCCB but i will have to pay heavily for engaging him.

That said, since I have benefited immensely from this forum, let me also share so others can benefit as well.

If you need guidance on RCCB and ELCB and why the former is better, then please find time to watch these videos:

I feel that my earthing is in order, but to test it. I will most likely need to engage a fit and proper electrical engineer for that task

Ah okay, I think it was a combination of the charger and the Gen that spoilt your device. The generator AVR probably didn't react quick enough to the charger being plug and probably caused a fluctuation in power output which your highly sensitive sound system couldn't accommodate.

I can almost swear that if you were on PHCN or inverter when you plugged that charger, this sad event would not have happened. A dedicated UPS to sensitive equipment also helps to handle situations like this.

Hehehe Hard luck.

This is why i have a Anker Multi-charger in my house and don't use anybody's charger to charge their phones. Just give me your phone and i will charge it for you even faster probably than your chinko charger.

Since then, that has been my position too, give me your phone, I don't need your charger. Unless I know you don't go cheap with chargers then I might bend my rule for you.

You responded to my question on GA Solar but the forum ate it up.

Please can you post again, and post any links as pictures or without the dots so I can respond

I beg to disagree.
One day , at my business, the 5kva inverter kept tripping with overload fault showing. This was an inverter that had no issues with 1.5HP submersible pump and an 1HP AC together on a normal day.
I will switch it back on, check the load (@700w) observe for a while, get back to my office and about 10mins later it will trip again.
Out of frustration,i went to the DB and I started isolating the building, section by section until we found one area that anytime we switch it on, then the inverter trips.
I then called my electrician who came, checked , and could not find the problem. Soon the same issues resurfaced somewhere else .
So we searched socket by socket only to discover a useless phone charger was the culprit. One of my staff, oblivious to my dilemma, wanted to charge her phone . She will plug it, power will go, she will remove the charger use her phone awhile then plug it again when power comes. When i isolated a section of the building, she jejely moved to another part of the building to charge her phone . That day was not funny.
I made sure i destroyed that charger that day before someone go give me heart attack

Apart from killing one of the channels of the amplifier, plugging in that charger gave an effect that seemed like it wanted to suck the life out of the generator, I don't know how else to explain it.

The sound of the generator changed and the lights blinking made it clear that something catastrophic had occurred.

Looked for spares locally and all the spares were fakes, not exact substitutes or unobtanium

Now imagine that a little act of kindness resulted in having to consult Electrical Electronic Engineers on forums and via email, buy the service manual of the amplifier in the US and ship to Nigeria, study electronics so as to read and understand the service manual, test component by component, report back to those Electrical Electronic Engineers online, buy the equipment to help me remove and replace the failed components, get feedback from those Electrical Electronic Engineers on which of those components to use as it, and which to replace with something better, import the replacement components, study component datasheets and compare with the original components in situ, then they told me that to balance everything, I need to perform the same surgery to the left channel.

It was very clear to me that such a mistake must not be allowed to repeat itself.

As far as I am concerned, you did very well to destroy that charger

this is interesting and disturbing at the same time - chinko chargers are so poorly designed that they are tripping off generators. and these things do not draw up to 1A of current. the other day i was in an argument with someone who was going on about how the chinese are helping us with these low priced products. i was arguing that they are shit and give far more problems than benefits. i would never have thought the problem was from a charger.

now if i say no one should use any strange charger in the house - lesson teachers et al - it will be as if i am doing oversabi

moral of the story - buy all those extensions with 2.1A outlets and distribute them liberally around the house. i have done that, so no one who comes ever needs to use their charger - just ask for a wire and you're good to go.

unfortunately, as usual, this cannot be guaranteed when one is out of the house,

That your staff is just behaving like village people, unconsciously though.

Good evening gurus in the house,


I had solar panels, inverter and batteries installed in my two houses by same installer but I noticed that there is no form of protection (Like Circuit breakers, lightening arrestors) in any of the two installations. I'm a bit worried and want to know what is to be done.

I am an Electrical Engineer and I expect to find some form of protection on the two systems.


Thanks as I await your inputs

Donarsy:


Have you called smksolar office for better understanding of the system? The solution to this problem is from the setting on the inverter, kindly go through the manual for guidance. Or call smksolar for solution.

Could youpost the solution if you know.
Sent email to smk solar about the issue no response. Same as their phoneline i saw online.

Or post smk solar nigeria phone nos you reached them on.

I hv same issue.have dumped the inverter for now. Very useless thing

jajajajaja Lord have mercy.
I could testify as well, I was having a degree programme done about 6 years back and lived in a student hostel off-campus. I was the only one in the whole community with a solar system 247 power supply.

Close people do come into my apt to charge while strangers charges outside and monitors their phone . On this day, my inverter went off, I knew it must be from their endless power extension, so I disconnected the socket and told them charging is over, switched on my inverter and it worked normally.

Then this next door neighbor lady approached, bros, abeg I need this phone charged, so I told her to plug it in and come back, voila.... She's the culprit, this time my inverter smoked and I nearly cried. So I asked Her, did she recently plug outside too, she said yes it was when she plugged that the inverter went off earlier. Mo gbe....

I tested 1600w qasa electric kettle today with nepa light. Though I didn't check the litre but the water was boiled at exactly 8 minutes.
I want to buy and be using it for day and night on solar.
Does anyone know another product with lower watt?
Night consumption is my little concern, though my battery bank is sufficient for such load.

. 15kwh LFP doesn't need pity for 1600w loads running for just 8 minutes, even though I intend to run it for 2hrs or more. I was only trying to check if I could see another product with a lower watt.

I'm not so sure, but I think 1600w for eight minute burst isn't too much of night use. Well may be based on the bank sha. My heater (I didn't bother to check the watt on it) sucks a massive 2200w during use for approximately same duration. The voltage on the battery bank still stays right where it started off.

Toh, 1600w for 2 hours for off-sun use is huge ó. But wait, you wan dey boil water for 2 hours 😲
