It's actually becoming more frustrating how sellers would want to intentionally defraud you and end up blaming their boys!!!

Innocent boys that's following their oga's directive would be dragged.
A customer paid for specific items and specific rating. You received the fully agreed price. Then you send nonsense and want your customer to believe it was a mistake from your boys... What business has the customer with your boys!

And the funny things is that, these sellers would want you to end up managing whatever they sent to you.
I mean, they'll feel that after the whole delay and probably, you're also desperate and need the items urgently, you wouldn't want to go through the stress of returning the items.
Because they would even tell you that you'll bear the cost of the returning waybill. And then they'll make it look like as you're returning those items, there might be delay in getting a replacement or a refund...
All manner of nonsenses and condiments gimmicks!

In my solar business lifetime, I've dumbed like 3 suppliers who never ever, in their widest imagination, believed I'll dumb them.
Yet, I've had one particular supplier I've been using right from the beginning.
Sometimes, even after I've paid, hell call to refund my money because either the exact spec of what I ordered for ended up not being available or complete, or he doesn't trust the quality of the ones available. His boys have also been sending my goods, when he's too busy to do it himself and there have never been issue, because he gives them detail instructions to avoid error.

All these recent "abeg no vex, na my boys error" are very unserious.

And it's also very annoying when a seller is readily available and responds fast when you're negotiating and sending money, but after that he takes the role of Mr President and becomes too busy with coordinating the affairs of the country.. Mtcheeeew

Still unfortunate how some sellers don't understand that integrity is very key in business sustainability. Honesty is non-negotiable.

House gurus good to see the flag is still firing. It has been a minute since I last posted here but I do check from time to time.

I do have a question. So moving to a new place in Abuja and the choice where to install panels on the roof poses a dilemma for me.

The house roof is at about 17 degrees inclination on both side.

The problem is one side aligns south east while the other aligns north West. The little I know about solar panel direction is. As much as possible align to the South. If not then south west or west. I always feel directly facing east or north should be avoided. (Unless your panel is flat in which case it don't matter )

In my case the west which would have been ideal faces north and the eastern side of the roof faces south.

What do gurus in the house advise.

Good morning Bigrovar,

I want to assume that you don't have much space in your compound to execute a ground mount, hence this dilemma; otherwise you could do a ground mount and orient/incline your array properly

However, if you're looking at roof mount, I don't actually know the size of your array. If you have 12 or more PV modules, I'll recommend you simply split them into two streams of Array... One stream on South-East and second stream on North-West. And then incline them approximately.
This, in my PERSONAL opinion, should be a good option.

NB: kindly note that two streams of PV Array on two different orientations would require each stream to have its independent CC (whether standalone or incorporated into a hybrid inverter)

Cheers

Dam5reey:
This Debate has been discussed, I don't just understand your Analysis..

I will take Felicity Lithium over your German Varta or Exide LA
LA will still be LA, if you use it at 80% DOD, it's won't last as long as Felicity.

Problem with LA is the Cycles life and DOD.

With Lithium you will still Discharge at 90% DOD without fears.. Funny enough the voltage will still be in a Good range..

HI Dam5reey...

Please, this isn't a debate at all.. Just making observation and trying to keep the thread healthy.

Now, the bolded is quite laughable. Varta has a designed lifespan of 10-15years and I've seen a man that, as at last year, his Varta batteries are 8years and still going.

I have 2 clients that have used their Ritar and Quanta for 6years 3months and 7years respectively before changing. These are facts. And yes, they don't cycle below 50% and both are using Magnum inverter

Now, who have you seen that have used Felicity lithium beyond 3years, that gave you the confidence to make the statement?

Yes, there are folks that have used Lithium even beyond 5years and counting. But felicity lithium? I strongly doubt

So please, that your bolded statement seems to come from a sentimental perspective, and that makes it a fallacy.
My problem now is not Lithium VS LeadAcid. It's specifically your statement. LA battery has proven to last very well when cycled at or above 50% DoD. As far as am concerned, there's No PROVEN record of longevity as far as felicity lithium is concerned.

Tell me that you've seen good performance with it compared to LA battery in terms of charge and discharge current, voltage stability even under heavy loads, among other; and I'll fully agree...
But until you're able to have a prove that felicity lithium has lasted even upto 5years, your statement is false, unfounded, and very misleading.

Cheers

obimind:
The future is now Sir. I am a living testimony that Lifepo4 is the sure way to go. I ventured into using inverter since 2013 though I added solar panels to my set up in 2015. I must confess that my major challenge all these years have been the early failure of my LA batteries. At a time I decided never to buy new batteries from Alaba bcus they don't exceed six months of usage before they pack up. I decided to start buying fairly used batteries that were put for auction by banks which never helped either but at least served slightly longer than the brand new deep cycle LA batteries. My turnaround in Renewable materialised when I reached out to EFURO who gave me a link to a guy who have been in this forum but on the quiet side. He is based in Lokoja (Kogi) state. His core is assembling and coupling of Lithium Ion and Lipo4 cells. To cut the long story short I was able to reach him on phone and we talked at length. After explaining my plights to him he assured me that if I can take a bold step by going lithium my story will change for the better. At first I thought it was just the usual market strategy which we Nigerians are used to but after due consultations with another guy that strictly sells lithium cells in Kano his name on this forum is (Tetralogyfallot) he sells lithium cells but does not build he still referred me to the Lokoja guy. That gave me the confidence to have a firm deal with him. All these are history right now bcus as I speak he was able to build a lifepo4 bank of 6,000 watts for me. Its been two months now since I started using that battery and I must confess that my experience at the performance of that battery has been amazing. I must emphasise that owing to the high cost of brand new lifepo4 cells I was not able to go for such. He rather coupled a grade B cells for me and attached a reliable BMS to it, but to my amazement that battery is performing way above my expectation. When he did a capacity test before sending the battery to my location I discovered that he was able to pull over 400 watts continiously for over 10 hours without the battery shuting down. He attached a battery meter to the battery which helped me and is still helping me to monitor the battery without stress.

Good evening Mr. Obimind....

I think we can actually always try to share experiences with certain type(s) of RE item technology without completely painting one type black, especially a type that has proven and is still proving reliable.

This forum deals with facts and details. And as far as this your story goes, it's completely devoid of details.

A lot of newbies and guests come in to this forum to get enlightened and its bad if they always tend to meet misleading stories

I'll go straight to my observation in your story. I strongly believe that the problems you had with your LA batteries (as far back as 2013, 2014 etc) weren't because they were LA technology. I believe they were as a result of misuse; in fact, consistent misuse.
Details that you didn't tell us here are the size of your battery bank and the load that you use. You also didn't tell us how you cycle it and how appropriately you were charging them.

We all know that LA has a big fault when it comes to maximum current you can pull from it at any time, and recommended DoD.

Imagine drawing 30ADC from a 20hr 200AH LA battery bank. Even the likes of Varta or US Trojan or Quanta would die within months.
Draw same 30A from a 200AH Li battery bank, and the battery would be smiling, and the voltage won't even dip. Drawing 30A from a 200Ah Li battery bank is even a "misuse"

I deal on both LA and Li and I always explain the Pros and Cons of each to new clients and allow them make their choice.

Folks are still using same LA, going to more than 5years and yet to change their batteries.

LA technology does not forgive abuse and misuse of any kind. Folks that understands it and are willing to abide by its "regulations" are still venturing into it happily. So, if you had consistently misused yours, don't come and dump unfounded conclusions here without facts and details of what actually happened, especially detail of your load, charging, and usage.

Just 2 months into Li technology and you're already concluding. I'll strongly advise you to study that guy very well and use it properly, otherwise you'll come back tomorrow to blame Lithium and now testify about NiCad technology...
Remember that those years, LA battery was amazing to you too until something started going wrong.

This is not for debate, as plenty have already been done, but to prevent new guys that are still trying to find their way around RE world from being mislead by your post.

Cheers

ojeysky:
Funny part is that cost of lifepo4 is almost (if not same) with a good lead acid nowadays (usable capacity wise)

Permit me to state that this statement is flawed and misleading sir...

You might want to be specific. You stated "good lead acid"... But didn't specify whether the Lithium counterpart is also "good" or one of the numerous low-grades

Are you saying that, for the same usable capacity, a pylontech lithium is almost same price as a Felicity or Luminous LA?... Very laughable

For same quality, Lithium is still far higher in price. Compare pylontech or BYD Lithium with the likes of Varta LA...etc.

There are extremely cheap lithium batteries with extreme low quality flooding the market.

Tomorrow, you'll see a 12V 100Ah Lithium going for 90k and someone would say its almost or same price with LA. Even when the real capacity and quality of the battery is very questionable

You sound like you can compare Felicity Lithium with German Varta or Exide LA. They can never be mate... Cheers

Thanks for your advice.

Are those diagrams in order and which setup from the two is the best for southern weather?

In diagram one, could the two pv arrays charge the battery bank simultaneously?

Is HA02 installation really necessary for tubular batteries?

Where could MNDC115 or 300 be installed in that diagram?

If all batteries are same brand, same rating, same age, and same technology, just parallel them into one single 24V 400Ah bank

Two PV Arrays can charge same battery bank, as long as the system is properly designed.
I have two PV Arrays on a single 24V 400Ah battery bank with 2 sets of inverters connected to the battery bank.
The two PV Arrays ALWAYS charge at the same time.
You just have to know what you're doing

This HA02 matter has been tackled severally. It's your choice. Just make sure you install it as you're installing the batteries... Not later.
And if you're paralleling all 4 batteries, use on HA02, then link the midpoint of string one to the string two

MNSPD DC should be installed at the downstream of the PV array; at the Line side of the PV-CC Isolation Breaker
MNSPD AC should be installed at the line side of the Inverter AC Input Isolation Breaker.

ojesymsym:
If you must try this model, you should be thinking of North and South, West does not even come into the equation at all at any time of the year.
It is better not to install solar at all than to have your panels facing West

This is soooo wrongly wrong boss... The wrongness of this statement cannot be overemphasized!!! Lolzzz
On a lighter note...

For 4 years plus, my PV Array setup is split into two: East and West. Even with fridge, TV, fan ON, battery can still float around 6:10pm, depending on sun intensity of course. You can NEVER have that with South or North Orientation, irrespective of sun intensity

That Sunset charging is usually very advantageous...

I mostly split Arrays for clients into South and West; or East and West... Other times, I just allow everything on the south. But if I must split, West MUST be a consideration. In fact, I split because of that West Orientation; that sunset charging helps the battery a long way through the night. Only few times have I used South and North due to constraints

So, if you're going for single PV Array on one Orientation, definitely South is priority... If you're splitting into dual arrays, West Orientation is inevitable; i.e South & West or East & West.
Cheers

Edit: I see Oshomo12 and Dam5reey already reacted to that... Cheers

samnaija:
Thanks very informative, pls pics2. Is the outer parallel cable between the strings not necessary. Also if I get u correctly in this kind of setup one battery balancer can serve two strings . Thanks again.

Hi Samnaija,

The outer cable is the looping cable, to parallel all the strings together. For Pic 2 methodology, you longer need to loop. Each string is independently cabled to a common bus where they are paralleled. Hope it's clear

And YES, one Balancer can serve two strings, PROVIDED that both strings are interlinked as indicated by the dotted lines... Cheers

mctfopt:
Thanks a lot for your explanation. Please can you add schema to help buttress this explanation?

Hi mctfopt,
I doubt every member need migrate to email to be enlightened. It's a vital info that everyone need to have access to.

Kindly find attached (Pic 1) what should be his layout based on the details he provided. With the looping method ensure the battery bank cables for +ve and - ve sides are NOT taken from the same string. Take one from the 1st string and the other from the last string. The first string shows the connections for a typical HA02 Battery Equalizer (or Balancer). The blue dotted lines are the links to form the "one giant bank". It ensure a more balanced setup, as he's rightly said. It must not necessarily be same size as the battery serial interconnecting links. The battery serial interconnecting link cable can be 35mm.sq or 50mm.sq, whereas the parallel interlink cable can just 6mm.sq or 10mm.sq (in Efuro's case). I also use 10mm.sq or 16mm.sq

Please, credit should go to oga Niyi... Sometime ago, I was faced with a serious unbalanced issue in a new setup for a client and Niyi took out time to explain this interlinking between paralleled strings. I've seen it depicted in HA02 manual but never give it a thought, until Niyi made it easy.
Accordingly, you can use 1#, instead of 2#, HA02 for a 2-string battery bank.

Moreover, Pic 2 is a better method to parallel the strings. Each string is independently paralleled with same length and same size cable to a common busbar... Cheers

Thanks for your inputs.
I am avoiding the hybrids because i am hoping i will use premium (maximized) CC and other solar components whenever i am ready to convert to Solar.
I have a mercury 2.4kva MSW inverter( In use since 2017) , it has a float charge of 13.5v which is similar to what Quanta requires. So i guess i am stuck with it until i am able to set up the solar components. (That means no pure sine wave yet ).

In addition to the bolded, you really need to Confirm the boost/absorb charge voltage of the Inverter.

As you might have known, Quanta specified 13.8V as their boost charge voltage and a maximum voltage of 14.2V (though I personally normally set the absorb voltage of the charging sources at 14.0V)

Just to add too, don't kill those Quanta with that MSW inverter... Better to change your inverter before you get those Quanta

Hi.
Please i need help with the following about microtek 2.3kva inverter, kindly assist with any of the questions you can answer.

a) Can the microtek inverter charge batteries when it is switched off but connected to PHCN light?( I heard that prag 2.5kva doesn't)
b.)Is the idle consumption for the inverter high?
c) Are there issues with microtek inverters?
( I want to use it with 2 200ah quanta batteries to be charged by NEPA light)
@mcTrinity, @ other competent installers, @ mictotek users and product sellers.
Thanks.

Just as has been suggested, since you're charging strictly from NEPA, you're better off with an inverter with a customizable charge profile. Quanta Battery has a very sensitive charge profile

Though I do use Quanta with Indian inverters, but always in a setup with solar integration; and charging is 95% via solar. That allows me to set the charging profiles for the Quanta on the CC
