auwal8377:

Hello, my JBD BMS will not allow charge or discharge and this happened after my 24V LIFEPO4 battery drained to zero percent (0%) (from Xiaoxing app). When the BMS is connected to the SCC, the voltage will rise quickly and register full charge delivering 0 amps. I charge it directly via the SCC to about 36% and still the BMS did not start. When I connected the load via inverter the voltage of 26.1V quickly drained to 17.3v and the inverter disconnected.
The specs of the BMS is (AP 20S006 20S 200A).
I tested charging the battery pack directly with SCC and also discharging with an inverter and it works.
It means it is the BMS that is the issue. I tried jump starting but it did not work or I didn't do it correctly.
Kindly help with the solution.
Attached is the picture of the BMS model too.
Thanks

Speedy recovery valto, i pray you get well soon and do what you are best at.

odimbannamdi:
Please, let's put Valto in prayers. He is seriously sick and has little access his phones

Cost without the trident thingy and the accompanying materials, assuming more than one pit is used for more effectiveness.

TechGeek777:


Does this price include lightening protection to the ground?

With grounding

TechGeek777:


Thanks for your responses so far, but I don't understand this your statement bolded.

When is it likely to go through the panel to the ground?

Is it without grounding or with grounding?

100-200k

For a simple one

Valentinooo:
Anybody has an idea of the cost of installing thunder arrestor. I think I need one

What is the charge controller or inverter you are looking to protect's voltage?

Myself50:


Something like this

In my opinion, Yes!

The risk is high if it goes through the panels to the ground.

TechGeek777:


Does it mean it's better not to ground it if there's no arrestor close by?

Thanks

tipsy242:


Good day, the inverter has already been sold. Thanks

A lightning arrestor or trident install at the highest point on a property to be protected with a very low path of resistance to the ground.

This is to allow for a point where lightning can go instead of through your house as that one nah fire or die sef

Ideally, PV shouldn't but if it is grounded, with no lightning arrestor close by, it could be an attractor of lightning at times.

TechGeek777:

Boss, what can then protect one from direct strike?

Does pv attract lightening?

If you have the means, get another cable to supplement the existing one from the panels to the charge controller.

This is so you don't lose your current as heat due to cable size.

JoeSef0:
I already used an 8mm wires to run the solar into the house, does it mean I'll change that to 16mm or i just need to change the wire i used in connecting the panels together on the roof?

Would you be willing to sell the equipment separately?

I am interested in the inverter only.

tipsy242:
I have a 1kva inverter and 220mah Mpower Tubular fairly used battery for sale (bought newly January 2022). Selling price is 130k (30k Inverter and 100k battery). Reason for sale is because I'm getting an upgraded inverter setup with two identical batteries and i was advised not to use two new batteries with used one.
Kindly WhatsApp +2348104591211 if interested.

Get a 16mm² guage wire and connect all the solar panels in parallel since it is a PWM controller

A 12V panel is already 18V Vmp, which will charge your batteries just fine; at 24V, you will be losing a ton of power due to higher potential differences.

JoeSef0:
My bosses here, I have a question

5 12v 180w solar panels to be connected in series to get 24v
How'd you go about the connection
Remember you need 2 panel's to make 24v.
The system is a 12v (inverter and battery) charge controller is an automatic (12-48v) 60a

Picture not attached!

Please note that a DC SPD cannot protect you from a direct strike but rather the EMI derivative of the lightning strike at some distance close to you.

Myself50:
Good evening house, this dc spd, can they protect the inverter when thunder strikes? Assuming the house does not have thunder arrestor.

@zeestone

Yes! it is working fine.

Typically, solar panels will produce 85-70% at peak of their working conditions locally here.

You were doing 78% of your capacity, i'd say that's a good one.

Congrats though! Enjoy !!

kristien4:
Thanks bro. The thing is i upgraded my panels yesterday.. 6pieces 580w solar panel. 2 panels connected in series into 3 places. Thats 2_2_2 in series, all paralled together. I just put it under heavy load. My growatt charge controller displayed 2730watts pv input.. 18amps pv and 90v pv. Its a 48v inverter... 4 pieces 12v LA battery is series..
Each panel 51v
13amps
580w. Just wanted to be sure its working fine. Under the heavy load, pv input amps stays at 18amps, While batt says 43amps. Was thinking the pv amps would get to 30amps and above or something. I should just believe everything is fine since I'm getting 2730watts from 3480w panel on heavy load.

Yes! you can.

Since this move is likely to be observed manually, try to note or track the movement of the sun through the day and check if the better part of the sun moves over the proposed solar installation.

Meklex:
Can I mount solar panels on my balcony? It's facing south east. Can it be able to generate enough juice?

Good day,

I will strongly advise not getting your equipment from the US based on
* warranty claims
* Aftersales support and other factors too relating with sub-region
* Voltage output differences.
* Logistics (Shipping cost)

Plus, quality is kind of relative to how much you can spend on a robust product. There are products available locally found in the EU and US markets known worldwide for their strong performance. For the lithium batteries, good brands here give their best too.

To answer your question
You need to have a solar consultant who will go on to recommend products that you can research and make an educated and informed decision on.

I hope this helps.

Nahum777:
Hi guys, I live in the US, but I want to implement solar for my family back home in Nigeria. I am scared that the quality isn't up to what we get in the US. Especially the Lithium Ion Phospate batteries. I was thinking of sending the materials from the US, but the cost will be outrageous. Also, the US uses 120V while Nigeria uses 220V.

My question here is, do you guys have reliable sellers in Nigeria I can buy from? And what brand do you guys recommend? Is there any reliable website you guys buy from? My family lives in Lagos Nigeria.

Your answers will be greatly appreciated.

The rough estimate of your system setup will be in the range of 16–17 million.

Attached below is the load estimation. The loads can be dropped to make room for competitive pricing. I am open and available to discuss more with you.

Akbil:


3nos x 1.5hp ACs
18w x 15nos LED Light fittings, 5nos laptops, 40w x 8nos security lighting, 250l deep freezer, water treatment plant, microwave, 8nos x 55w standing fans, etc.

two-story building. The roof top measures around 10m x 12m

Thanks for the heads up, i'll see to it and revert back so you can make adjustments

Okay!

There is a link on my bio (can't post it bcoz of spam bot), use it via your PC and input the loads as they will be used in reality.

* Share the screenshot of the final results

* Share installation location information with respect to the building

* Share a picture of the roof ( location on Google maps is not needed now due to privacy)

Akbil:


I'll appreciate if you can provide the questions here so everyone can review. Later we can go private

Can you please reach to me via the contact number on my bio or profile

There are more information to discuss to come to a refined solution

Akbil:


Good morning.

I need complete solar system for a Duplex with 3nos inverter acs.

Please give estimate and bulk park pricing.

Happy new month fellas

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 Solar 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.

norblinks:
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.
