More than a month ago, @Leun reached out to discuss a possible solar solution, which we first need to be on the same page.
We referred him to our Off-grid energy calculator (link in bio).
After careful planning and several conversations.

We executed the installation with a 5KW Growatt, 580W Jinko and 7.5KWh Lithium ion Xtra power battery.

Thank you for your trust that we at @Rendezvous [color=#000000]Solar[/color] can deliver on your project and your hospitality. Gracias

Looking forward to discussing further

FEGEITOK:
I like to do business with those who have a command of the subject/product they are dealing on.

That is what I do so that is what I look out for.

I will meet you on WhatsApp for further discussion.

You have done justice to the subject matter.

Thank you.

Good day bosses, please can someone help recommend a good Solar installation training institute in Abuja .


Thanks in advance

NO, I will recommend an MCCB when you want a CB between an inverter and battery or where appropriate amperage is needed.

Except you have a powerplant of several PV arrays connected, an MCB of 125A would suit for a 100A charge controller

And a max. Of 63A series for PV to charge controller

FEGEITOK:
Would you recommend the use of MCCB in between a charge controller/inverter and solar panels OR between batteries and a charge controller/inverter OR BOTH?

An MCB is a miniature circuit breaker while an MCCB is a molded case circuit breaker molded as like with ceramic attached is a picture too

bassdow:
You for try add pictures of MCCB and MCB in case we sabi am with another name. Who knows, maybe we don use am gan sef but no know say e name na MCCB or MCB.

The thing is you can't see an MCB of 160A, MCB the big types stop at 125A that's why their model is xxxx125 while smaller MCB are of model xxx63 meaning that is the maximum you can go for their amperage range

FEGEITOK:
The MCCB is several times higher than the MCB

Researched it.

2 pole 40A AC MCB -4,000

2 pole 160A DC MCCB -54,000 (different from MCB, please check for difference between MCB and MCCB)

BOTH breakers are FEEO.

FEGEITOK:
I want to put another inverter online as an upgrade to my existing renewable energy setup.

I need pricing for 2P-40A AC circuit breaker, 2P-160A DC circuit breaker.

Please provide both pricing and brand name

Interesting! That must have caused some serious data breach

FEGEITOK:
I used to encounter trojans. I remember finding a set of files that was responsible for siphoning data from a certain government machine to the outside world via email. Long time ago.

I have since stopped doing that kind of IT so NO, neither have I come across it in a client's establishment.

Short answer is NO!

Ordinary fixed rooftop of top equipment is problem for some due to cost, not to talk of solar tracking array, the reality is that i don't see it being economical solution here in Nigeria, my POV

FEGEITOK:
Is anyone doing this in Nigeria?

Tracking the sun makes solar panels more efficient on land and water

This is what I call painstaking troubleshooting, I am not vast in knowledge of computer but I took on myself to know a bit if this and a bit of that when It comes to I.T

I told a friend one time that the quickest way to gather knowledge and experience is by working with the big players, because there are always new toys to play with at one point which you may not be exposed to if working for yourself.

As a rule of thumb, I avoid certain things that would run me into trouble with computers.

BTW have you ever gotten off of a ransomware before?

FEGEITOK:
Speaking of the value of knowing your stuff inside out.

Only those with ideas and understanding will appreciate the wealth of knowledge shared in this post and the prerequisite conversation, that alone sef is enough to get you kicked in the right direction.

FEGEITOK:
@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

Without the solar system nko

500,000

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
