@litaninja

Let me correct one phrase.

You know networking inside out, should replace the phase that are into networking which I used earlier.


Everything you said up there is valid.

I started by fixing PCs ( hardware) to software to running networks to supplying software to enterprises to architecting complete solutions from scratch incorporating software, hardware and consultancy.

Before I sell a solution, I actually personally play with it and have a working knowledge of the same.

My point is that knowing the basics and knowing them well is non-negotiable.

I use cybersecurity to get in some doors, but I am versed in several aspects of IT and I keep learning. My biggest grossing deal wasn't a cybersecurity deal, but cybersecurity opened the doors for me.

When I started, I bought books on subjects as diverse as open source intelligence techniques, database security, website security, web hacking, networking, windows server administration, computer evidence collection and preservation, Oracle hacking and devoured them, Official Certified Ethical Hacker also.

When these certifications came out, I bought the Official Study Guides books: Certified Wireless Security Professional (CWSP) and Certified Wireless Network Administrator(CWNP).

You need a foundation without which you cannot understand certain concepts. Money does not just appear from nowhere.

How do I reach you?

The guarantors are fill in based on agreed terms before start of process

isangjohnson:
For defaulters, I'm just wondering how you would be able to recover your money.

You can reach out to me for this, we offer a plan in line with this, should you meet the criterias.

icjunior:
Light just got bad in my area and I need solar panels all of a sudden,any organization into solar panels loan😁

No, only fan and heater with control

isangjohnson:
Does standing hair dryer machine have compressor?

I studied and used both for clients at different times and they perform very good with decent energy harvest.

Either one works well, choose which your budget covers.

We can also get them for you from our authorized dealers

icjunior:
Can I get yingli or Era solar panels?

Are they good options?

Very well then!

Puvo:
I’d prefer something I can easily get access to you guys if I encounter any issue. Lagos too far

It can be sent to what ever your location is across the country.

In fact, the components are more of a plug and play rather than one that will rack your brain.

A layman can even put the whole setup together with Bare knowledge.

We can also offer you a virtual update and follow up, when faced with difficulty

Puvo:
Too far

Thank you

odimbannamdi:
Nice one, bro! Weldone!

Lagos

Puvo:
What’s your location

Thanks for shedding more light on this, I always thought only those INEC battery have a custom made charger.

Valto:
dedicated 12v 30A lifepo4 lithium battery chargers available @ 35k displays red light when charging,turns to green when battery is full.

Love the detailed findings

I wanted to mentioned earlier that it was the change over that caught fire due to the four screw holes under it.

I also think by now people should know that
Your max. Charge current plus estimated max. Load when converte to power should be divided by expected AC voltage to know what their ac breaker should be.

More power to your elbows

jonescosmos:
Nice for you to call my attention to this incident. This issue happened when I had a single Unit 16KW Deye Inverter. I would itemize my responses.

1. Those HIMEL breakers came with the Inverter, and they worked perfectly well. I made a comparison with the ones I later bought by myself and noticed that in fact these 2 that shipped with the inverter are original.

2. The AC-In breaker did not cause the fire. As a matter of fact, it did its job perfectly, if you look at the picture again, you will notice that it tripped, preventing further damage.

3. The issue was caused by the HAGER changeover between the AC-IN Breaker and the AC-IN Current Limiter. The Hager switch I suspect must have overheated and caught fire eventually.

4. THE MAIN CAUSE AS I INVESTIGATED: This 16KW DEYE Inverter had 290A Charging power. The night before I ramped up the charging rate from 120A to 240A because I added another battery (15KW Felicity) and the Datasheet shows that battery needs 120A charging rate and if you have X number of the batteries you should use X*120A setting on your inverter.

5. There was no grid at the time when I did this change. So early in the morning when the grid came and battery started charging, kids’ school preparing also started, Kitchen Cooker unit and Water Heater kicked on, Two Children's Water Heaters Kicked on, and the Overall Amperage on the AC-IN circuit ramped Up to around 72A which sat there for about five minutes or so, The HAGER Switch had gathered heat I guess and started melting. The HIMEL Breaker shut down, but the switch continued to melt internally and eventually inflamed.

6. Results from N0.5 above was gotten from my Smart Energy Meter I has Installed after NEPA Meter. So, I replaced the AC-IN Breaker because I saw that my AC-IN Current ramped above 63A just before the issue. My choice of 125A was that DEYE in the Inverter User manual recommended a 200A Grid Breaker. The reason why the Inverter was shipped with a 63A breaker remained a mystery to me.

7. The exposed wires from the ferrules were due to the heat that resulted from the fire.

8. I can beat my chest about my Screw contact torque and tell you It wasn't the case at all. People find it difficult to loosen bolts, nuts, screws, etc., that I tighten because I torque to specification and most people lac appropriate torque tools.

I hope I have been able to clear the doubts here.

It won't work ... It is an off-grid inverter. NEPA can't charge through the inverter. Except you have an independent lithium suitable charger

Puvo:
Without the solar system nko

500,000

adebayo3449:
Good day my ogas here.

Please kindly help out.

(Picture attached)
I'm planning to set up a system where by I'll be able to use 150 watts fridge for 7hrs during the day from 6am in the morning to 1pm in the afternoon and also use 60 watts from 7pm in the evening till 7am in the morning.

(Since you use less than 1KWp, a PWM isn't bad, if trying to work on budget)
Please what is the cheapest way to achieve this. Is this possible with 12v and a good mttp charge controller?

If yes or no, please I beg you to suggest the type of panels, battery, breakers and the size needed.
Thanks so much

Also, I don't want to charge with Nepa light at all, except during cloudy days.

Please help

Target is to achieve this with the cheapest means possible without compromising quality (target is to change ba3 once in 3 yrs, hopefully I'll have enough money to expand before then).

(When a 24V solar panels are used, you have no choice but to use MPPT charge controller)
Also another question(another setup).
Is it advisable to use a single 600 watts panel on roof or use two 300 watts for a 12v setup.

Thanks so much

olopan:
I'd like to commend Valto for his thoughtful ideas in his business, the battery box done for a 280Ah used for a member here was quite rugged and robust in it's structure.

No rickety sounds, all joint very solid and no gap for large particles of dust to enter.

It even held up to 60+ kg body weight and it withstood such heavy weights of the battery, all i can say is well done to him. This is my review of his build, and the circult breaker used was sized appropriately.

Guys check out this twitter post on rooftop types to avoid when planning to install Solar on your building rooftops.

https://twitter.com/oloyeadeniran/status/1693350994086658509?s=20

Nice installation you have there with a well built support too, you can get the panels to generate more by up to 5% if the ground below is more reflective by flooring or back filling with white sand i.e. if the above has not been done.

Justice629:
Apologies accepted and below is the array mount.
Bright cloudy days are when bifacial truly excels not dark cloudy ones.

They have office or warehouse around testing ground ...or Jericho side.

I can't remember right now.

You can use Google with info I mentioned above

yemi2plus:
Please I need recommendation on reliable Luminous Battery sellers, preferably in Ibadan.

Thank you!

Pardon me, but the pictures you posted was my reference, which looks like they were placed on a roof, anyway my sincerest apologies.

Justice629:
Am amazed by how you reached the conclusion that my array is roof mounted :, it has always been ground mounted.

Assuming they are new, you wasted their potential.

Bificial panels are not meant to be installed like a regular panel as they use the albedo of the surrounding to generate more power (i.e. reflection of light to the back of the panel), thereby generating more power.

If you wish to really do the work. Your roof top is definitely not the 1st choice, secondly if that's your only space then installing them conventionally too isn't your preferred installation methods.

Wish you all the best.

Justice629:
Original tier 1 JASolar bifacial panels installed with similar results as my old questionable panel grade in this dark cloudy days.

It's for a training, I will discuss with them

cluewebhost:
Working perfectly.
30k
It was initially 60pcs, I've installed/sold most and have 4 surplus.

How much and is it still working?
