I consider this your advice very strange. People generally upgrade from 12V to 24V yet you are suggesting otherwise. Is there any new info about 12V systems we are not aware of?

oldienavie:

I am not suggesting 48v, I am actually wondering why you are not using 12v?
So because you have a 24V inverter you have decided to let it determine how your system will be.
I hope you are not being pennywise and pound foolish sha.

Ferdiwar:
Good morning all,
Please I am planning to go green and need your input on which is a better option between flooded and AGM/SMF batteries as I plan on getting it.

With the proper maintenance (battery rotation, equalization, etc) which amongst the 2 will last longer (I can't currently afford to get a new 24v lithium bank).

Proposed set up.
1. 1.5kva 24v luminous hybrid inverter
2. 4x 350W panels
3. 60A Techfine or Powmr MPPT CC
4. 24V 200AH to 305AH battery bank.

Any other other advice will be very much appreciated

Thank you

Flooded? be ready to be buying distilled water, and maybe also be ready to use a hydrometer to test the state of the acid

The other type AGM/SMF - not SMF means Sealed Maintenance Free, that is what I went for.

I got Quanta. I am buying Deka next. Those seemed to be the best that money could buy locally.

I also have 2 No. 1.5 KVA inverters, Schneider brand. But since there is a partnership between Schneider and Luminous and Schneider bought into the brand, I want to believe the Luminous must be that good.

I don't yet have solar panels, so no comments on the MPPT. My alternative charging source is my generator.

My batteries are 12V 200AH. Why buy any less? It means reduced backup time.

My setup is a 24V 200AH x 2.

Can't comment on how long it will last, cause my setup is not quite a year old

Tubular /flooded batteries is fine, it depends on how heavy you use your system determines how soon you refill with distilled water. Some systems is twice a year, while some is once a year to top up batteries.

There are guages on the batteries that signify which cell needs distilled water.

Don't know it is because of the weather up north, but my brother uses Tubular batteries and has had to refill more than once in a year.

What's your experience if you care to share?

Here is my experience, I have decided not to share the name of the vendor, not that with a little bit of digging and adding 2 to 2, the vendor cannot be identified.

I contacted one of the most prolific advertisers of solar panels, inverters and batteries on nairaland.

I was given pricing.

I then delayed in concluding the deal.

In the meantime, the advertiser reached out to me a few times to inquire about the deal. I did not respond.

When I was finally ready to deal, I sent the advertiser messages, but the messages were not delivered.

I conducted some tests that revealed the advertiser had blocked me.

I smiled.

I then said what nonsense!

In my line of business, clients and potential clients can ask for quotes and only buy 9 or 10 months later or even a year or more after, I never ever think of blocking them because they did not buy right away or did not respond to requests for the status of the potential order.

I then started looking for those who sell the same thing locally ( I am based in Abuja, the advertiser is based in Lagos).

I found one, but he said he didn't have it in stock, but pricing was perfect. I told him oh great.

Will buy next week.

I went to his office around 4pm and he complained that the equipment isn't in his store, that it is in the warehouse, and that it would take some time to get it, I said I would wait, he said its late that I should come back on Monday if my memory serves me right.

I sort of got the vibe that this guy does not have the equipment and is sourcing it from third parties.

So, I then started doing the same thing he did, went to the vendor site, got the list of authorized dealers, worked the numbers until I got the guy whose bread and butter is inverters, batteries and solar panels.

I ended up getting it cheaper than the cost of buying it from Lagos, and without the need to pay for shipping from Lagos.

If I wanted to buy from anyone, I would buy from those who have contributed immense intellectual capacity to this thread.

Why should I buy from someone who is only interested in come and buy from me, but when the potential buyers are asking questions, they don't answer.

It is pretty obvious, who is in it for the money and who is in it because they love the field.

If I wanted to do something this technical, I would get the vendor training and certification to back me up, any other thing, it is clear this is a way of making money and not something those advertisers do because they love the field, in fact, they will drop ship as soon as they can catch the scent of the next big thing that can bring money.

Like I said It depends on how you use you discharge your system, besides I am down south. Am sure the temp up north is a factor.

This useless Kiekie again. Even the blind can see..

He must be cursed to think everyone who contacts him must buy immediately. He is just a low life modafucker who deserves to be inside one village with no civilization.

No decorum, no wisdom, no tact, no customer support, no patience, no intelligence.

Cc samnaija.

Any tubular battery that requires topping up once a month is either being charged poorly, with less than 14.3v or isnt carrying any serious load or isnt being cycled regularly...ie rarely goes above 20% DOD,.....2 to 4x a year is normal topping regime.

Too frequent topping like once a month accompanied with battery getting hot to touch is a sign of a dying battery

Internet Father, in your mind, you are old enough to be someone's father. The internet keeps making morons pompous. Since you don't owe me any explanation, we also have no use for your unsolicited reviews. It is fools like you that has kept Nigeria where it is. You want to buy a foreign product, you go read reviews. You want to buy a Nigerian product, nobody wants to say anything bad about anyone. Now, your roof is 2 million naira for just one side. How much did you roof your house again? 6 million naira? Liar. Are you scared the installer will give you a slap over the internet?

Again, if you cannot name who did a bad job, crawl back into your hole and hide. If you are truly a father, your kids must be ashamed of their cowardly father!!

Would this house want me to release transcripts /receipts of the conversation between me and the advertiser?

From the story you told, the guy only blocked you which led to him missing a trade. Not like he defrauded you or insulted you. Right?
Your gain, his loss. So why stretch it further.

Because people are asking for reviews.

Reviews on products and reviews on sellers.

It would serve that purpose.

It can be done without adding to the length of the thread. The poll is open for 48 hours. If those in favor of the release exceed those who are against it, it will be released, and vice versa.

It might also help vendors to realize that when you operate in the public eye, you may need to be circumspect in your dealings with clients and potential clients.

It might also steer clients towards more reasonable vendors.

i cannot overemphasize the frustration most of us experience with dodgy hustlers

i stopped using inverters in 2014/15 because i got tired of battery whackamole. this set lasts 18 months, next set last 6 months. because they are batteries, there is no way of telling if they are used or not. all you need to do is clean them up, tweak and sell as new
and then you have the people who rebadge 100ah batteries as 200ah batteries

so yes, i think we would all like connects to reliable sellers [with caveat and disclaimer because, las las, na still naija we dey, and i have seen character vaporize on this platform]

even on nairaland the trend i have always seen is after a client is frustrated and calls out a dodgy vendor, after the issue is resolved, the thread goes down the memory hole , so the vendor is able to continue as before with another unsuspecting client

When people complain of failures of equipment I just laugh. You cannot eat your cake and have it. Many will come request for quotes and will tell you it's too expensive, next thing they will get something cheaper(mostly from people that cannot offer after sale technical service) that works for a while and then pack up. I will say this again, solar power is not cheap. We already addressed this in previous threads.
2 to 3 pages back, someone just bought sunfit batteries, some will buy that stupid yohako controller etc and that's because it's cheap. Many users here just want to eat their cake and have it. If it's too cheap just run.

this has always been the way
why is why FEGEITOK advocates PATIENCE and taking your time.

the irony is that so many of these low quality items you have mentioned would be sold at the price of the high end items, complete with false guarantees

we know how it goes

To me sha solar is still affordable it depends on wat u want to power. No b everybody wan power electric iron, kettle, hot plate, ac, and the likes. Most just need sth to push light, tv, lappy etc.

I still feel uncomfortable for someone to get an installer to install a 12v system. Why? No b to follow instruction manual or online diy?

i just dey laugh since.
we know dem now.
thank God you have not been ripped off ur hard-earn funds.
1. on this forum dey (marketers) are out to rip u off if u dont do ur findings well. 2. even at dat, u rarely enjoy warranty within valid period! 3. as a diy forum, dey hardly make any review of their products for instance difference btw series of growatt inverters or real monitoring of sort.
just blind list of product with their outrageous prices that may scare off new entrants.

What it means is that, you'd spend more and probably have more difficulty getting your setup than if you were to go 12V....

Having said that, I am not a solar expert but you didn't tell me a reason for going 24V instead of the more common 12V.

If you are powering an industrial complex your savings/gains might be significant if you choose 24V but if you are just powering items in a 3 bedroom flat, not sure it will make much difference from 12V which will be easier to source and probably much cheaper components.

The panels are also going to be 24v

Using a 12V system will make me to run the batteries in parallel and charging it will take time and might end up dieing as a result of lack of adequate charging.

2ndly 12V system will limit the number of panels I will use (60A charge controller max out at 800W on 12V system while with 24V I can go up to 1.6KW). Which will not enough for what I want

U r misunderstanding me sir. I'm not talking about the size of the project but quality of materials/equipments. There is a certain minimum you shouldn't go below if you don't want headache and you want value for your money.
