I personally don't advice you use a pressing iron (1000w-3000w) on a 6kva inverter in suster

as a catholic, i don't like what mbaka did in the last election





sincerely speaking, mbaka screwed up. i least expected him to say all what he said in the last election, the church should be separated from politics



i still believe in his prophecies though

mbaka is here With me at attending to urhobo weed

most you who have not experience Nestle interview hear these. nestle does not use dragnet for their test. last year when they conducted maintenance technician interview, it was a kind of discussion class though, current affairs and general knowledge. its not even a competence test. years back 2012, it was same for trainee technician. now i believe the same pattern will follow to o. so lets hope and pray. last year again, some did a kind of questionnaire, you , nestle is not predictable. dragnet questions are not worth learn or hustling for. just ground yourselves on the needful. Goodluck all the way when it finally comes out.

Brother your case is very simple. All you need to do is to go to the office of the directorate of public prosecution with your lawyer and write that the court is not doing the needful, I believe this case should have a bail out terms . Then if the DPP office is not doing anything, then write for a case transfer to High court because the magistrate court lacks the competence to try such case. So the earlier you act the better it is for you. I believe the state is the one trying your dad. So you can petition them if the needful is not done. Sir I implore you to act now. A case is capable of being transfered to another court or state if the prosecuting state is not ready to try the defendant. Godd luck as the lord grants your dad freedom.

*****AVOID ERNEST NGWU*******
This guy claims to repair inverters. We took 4 Inverters to him for repairs. He claims that the board and Mosfetts were blown. On the 5 kw units he claimed that the charging port was bad and the other had issues that he could not explain.
He denied repairing the 5 kw units that we never gave him 5 kw units. I have them and one of the readers here took it back to the client with me.
The defective charger port still does not charge the batteries.
The other inverter that we took back to a client last night the ATF function does not work, the charger light comes on but it does not charge the batteries. The fans in the inverter don't work. The most glaring was that the display on one of the inverters was no working and he did not notice it. So far two out 3 are bad. We made him return the 4 th.
HE IS A FRAUD, A LIAR, A CHEAT.

Please avoid Ernest Ngwu at all cost. He is a quack and has no clue what he is doing. We avoided repairing inverters in the past and our first attempt has ended in failure.

Richmond74 I respect your take on this issue. chris8196[b]

Richmond74 I respect your take on this issue. chris8196 making it a public thing is not the best. I have few questions for you. As an installer, when you get to an office where inverters are being repaired, you will definitely know. I don't blame any on this issue. There is this you need understand on the issue of installation and repair. Too many persons rush into installation without understanding what and what are obtainable inside a rugged inverter. At least if you know what are found there and their functions, you can comfortably know who is real of fake. I will make a serious disclosure here . The recent inverters do have a particular problem either inverting problem or charging problem. In some cases unable to start ON. The cause is this : in recent technology of inverter, we use H-bridge inverter system than is powered from the mosfet drives. The oscillators are programmable in that they use micro controllers like the ATMEGA, PIC or DSPIC. All this are mostly programmed with C# language. You can copy the program out if you understand what I mean. The mosfet does 3 works(as-switch,amplifier and chargers) the chargers are smart that's why they can charge on three stages (bulk,absorption and float). So when the mosfet allows a current which is above its rated current , it will fry despite all odds . There are virtually so many microchips inside the inverter that does different jobs like powering the lcd, sensing the voltage, overload, and short. There is another circuit known as the feed back. When the feed back is down, sir the inverter will always drop in voltage when there is increase in load. Very bad. The rectifiers are the bridge diodes and the voltage regulator IC's ( the 78** series) . So sir you need to understand why some inverters are transformerless yet the same power with the bulky transformer sinewave inverters.

I rest my case
Good afternoon house

This is exactly the way I was smiling at same age when I heard my dad telling my mum am the one to inherit his bureau de change company

Share your interview experience for those who attended so those who didn't will be updated! Thanks and congratulations to as many who will finally fill this space, I believe my fellow brothers in NL will be in charge of this position.

yes you can, there is what we call TNC system of earthing and this is the type you need do for your system and it is very effective for inverters and solar system. i have done that on the product and will recommend you do same. battery terminal grounding is best when the voltage is very high like 360v in some 20kva inverters. follow richmond74 and chris81964

Braaad:
Thank you very much for your response sir... One more question please...
can I loop the AC and chassis ground together or should the chassis have and solar array have a separate grounding?? Thanks in advance for your response

Noneroone:
He waited for the dust to clear

a governor for that matter

my western brothers are very brave

ambode akpa amu ( I mean he is just a penis)

thanks for this, i have argued with a so called installer over this issue of luminous low charging current, he insisted my FLA battery is inferior or bad due to the system unable to charge the battery. i went on proving it with a DC clamp meter yet he wasn't convinced. Richmond74 kudos again

richmon74:
Theres is no way you can talk about Luminous when you are talking about flooded battery.
First of all it charges battery at 16amps and secondly it can't disulphide (equalize). So among the two PRAG might be your only choice.

PRAG offers you battery type selections which keeps your charging as close as possible to the battery manufactures specs and also gives you the DOD switch which is a great feature for renewable energy battery maintenance. I wrote about this in details in my last review of PRAG inverters.

just send me a direct mail to optimixim@gmail.com or sensewill@yahoo.com or call me at 08167327440. at your service sir

just solar

Just me

sir like i said , i don't have time for persons like you mr man. my picture have said it all and my signature a proof. i don't claim guru but not to stoop low for your discussion sir. if you need more clarifications on the reasons why 33kv, 11kv was transmitted to theor local. he said they do have enough public autonomy sir. so go and sleep. i guess you are in lagos, come to ipaja transmission station and ask of me sir. they will direct you to my work point........ i hate it when one criticizes with no facts........ answer it if you think you are electrically good......

gists:
Better! If you knew this before why did you ask the fo0lish question and you call yourself a NEPA staff. OR can safely assume you just checked on the net? If that is the case, I am happy I have forced you to read.

As a professional in the engineering field, I have interacted with many discipline engineers (mechanical, civil, electrical, pipeline, chemical, telecoms) and I can talk reasonably well in many of the disciplines. So most times, I know when someone makes a nonsensical statement like yours.

gists:
YOU SHOULD BE SACKED!!
And I seriously mean that!! If you cannot identify the voltage level by looking at the lines. Half almajiri education from gej university is worse that disease. No wonder our electricity industry is this messed up if people like you are the ones managing our technical issues. This is even common knowledge that many non-technical people know that are different poles (with different heights) for distribution and transmission. And you a supposed NEPA/PHCN staff cannot tell the voltage level by mere looking at the pole/lines.
I thought I was talking to a learned person - no wonder your initial post betrayed you even when you tried to sound brilliant.

u see the in-depth of your myopic disease. I asked you a question, you have messed your self up sir. All transmission system voltage can be identified by the following factors: the number of rings on the insulation disc, the length of the insulation, the shape of the grid, the number of lines running through the grid sir. Hahahahaha olodo. I pity persons like you who don't know that they are olodo! Pls go and learn I am busy with engineers sir. Olodite.

https://en.m.wikipedia.org/wiki/Overhead_power_line. Open the link sir and stop this your cheap advert ok. Back to work olodite

more pictures sir

what determines the power is not the voltage sir rather the transmission transformer power which have a designation for the transmission line which denotes the power. Note i never said power is unlimited rather i made a simple point with-respect to OP's comment and grievances. i will not argue further with you . i worked with Nigerian Nepa for five years. look at my picture and enjoy. BTF can you identify voltages on power line by just looking at the grid? i pity you and your university theory. come and learn learner..... i rest my case for technologists.

gists:
Prof. It just show how ignorant you are. You tried to sound brilliant but your post betrayed you. So in you own wisdom, power-lines don't have capacities or limits? Can you just keep adding streets/estates/communities to it? While this particular case may not have been overload problem, you can't rule it out as well as disturbances/faults on the line caused by them. Ask yourself why then do we need the 11kV lines at all? Why don't we all connect to 33kV or 132kV lines or better still why don't we connect to the 330kV since these lines are (according to you) "power unlimited" and have power flowing though them more reliably that the 11kV lines. Surely the conductors have enough capacity to handle the current and the voltage at this level is even higher - thus reducing the heat.
What they fail to teach you in numerous gej universities (glorified kindergarten) is that there is classification and separation of consumers. No sane PHCN official will connect you to these lines just because you want to have steady power or because the line can carry the load. Some are dedicated for transmission, some are dedicated for industrial consumers and the other for rest of us.

With all the heavy load the industries use as you pointed out, how many times have their transformers or other equipment failed compared to the numerous transformer and other explosion on consumer lines. Forget the fact that many of the industries run of generators, ask yourself how many times have you heard Guiness, Cadbury, Nestle, 7UP, Dangote etc have to shut down production because of a fault that was caused by another manufacturer on their distribution line?

The point is, they connected to 33kV line which is for of all illegal - except if that is what was planned and installed for that community otherwise I can bet they have either somehow introduced series faults or caused some overload on the line (which the OP will not be aware of)

gists:
@the bolded.
YOu are part of the problem. You are not supposed to take power from the 33kV line. That set of powerlines is reserved for industries. The bulk of the faults on electric installations come from end users (i.e residential users) . You individual consumers have brought down that line with so many faults (which is typical of residential lines). Other reason could be that that line has been overloaded. It was supposed to serve heavy loads from the industries and it now has to carry more load than it was originally designed for. Also note that your community may not be the only one connected to that line. Other near-by communities too will be encouraged to do the same illegal connection thereby compounding the problem.

So, face the consequence of your action and the PHCN official that connected you to the industrial line should be prosecuted.

I term this your post trash in electrical transmission line, there are some areas where double line doesn't need to go to a particular local, if the 33kva is for industries, why can't it handle residence, the industries run inductive loads(motors) which have a high starting current, yet the line handles the load effectively, let me ask: do you know why voltage is stepped so high in a transmission line? When the voltage is high, the current gets lower, there by heat generation will be at minimal.

Power = voltage X current

Heat =(I^2)R

You see the consumer is not the fault sir. If enough power is generated, the cables can handle as millions of volts as possible with low current kept constant, the whole nigeria will be powered. If you are in doubt, I will prove. Our presidiot mama mmadu bu garri ( somebody's mama is garri) is as dumb as his maloooo!
