Please, maximum of how many months can one mix old LA batteries with the new one?
I know the battery must come from the same manufacturer and must also be the same amps.

my brother,
it's not really advisable to mix old and new lead acid batteries but if you must
(either because of financial constraints or other reasons), it shouldn't be more than
six (6) months apart. and they must be of same spec, same brand (ideally) and try let
them be same year of manufacture.

lemme tell u a story.
Back in 2017/2018, for a business place with 1hp inverter ac, 1.5hp sumo, 12 x 250watts panels.decent phcn >12hrs daily on the avg
i had a 4 units 12v x 200ah battery initially...about 8months later, i realized that i needed a bigeer battery bank, against the better advice of people, Niyi especially...i went ahead to add 4 more new batteries to it, installed a balancer and even changed the cables to be the same size and length, used a busbar, but within 1yr of doing this...my digital voltage ddisplay caught a battery failing, i quickly replaced it, and hoped for the best....but alas within 6months..2 more started showing signs of being weak...i yet again replaced them...but u wont believe that didnt solve the problem...to cut the story short, the business later folded, and out of the 8 batteries in the setup...only about 3 were in good health.

so my first advice is....dont do it.

but if you must do it, i suggest you get adigital display for the battery...and b4 hooking them up...first use a 12v charger and charge each battery full, then hook all of then in parallel and charge them again for minimum of 48hrs/leave them to balance out themselves in parallel.

In the last few weeks the forum here has been a bit edgy with a lot of raw nerves and people all out for each others throats. I believe most of us here wish to hangout with people of like interests, some are hobbyist, some are professional installers , some are marketers with a lot of admixture in between. While I had sold used batteries to Keikie and bought used batteries from Ojeysky in the past, I will find it laughable if someone calls or views me other than an hobbyist.

Like in any public forum, if you request for advice then be prepared to receive a potpourri of advices. the onus is on the person to take what suits you. It is not by force to take any advice from anybody but I tend to really appreciate the vocal people in this forum ready always to respond to peoples questions and queries. Yes, YouTube is there and Google but thanks always for deeming it fit to take time out to respond to my questions even if you have something to sell!

I have a friend that I introduced to renewable energy. four years on, he is still very comfortable with his single 100amps 12volt battery with 2 150w panels and a cheap 20amp pwm CC. He linked his 2 DC fans, six 2w DC bulbs, CCTV, 2 Tvs and swore to me recently that his life has never been better. He has no wish whatsoever to increase anything in that setup. I respect his position and don't call him names. His setup cannot last 30 minutes for me and I sincerely cannot imagine living with that but we remain civil to each other.

Hi everyone,
I need your sincere advise.
I am about to purchase a 50amp mppt charge controller.
I intend to use it with a 200ah battery.
I understand that the maximum charging current for a 200ah battery (Lead Acid) should not be more than 30amp.

Is there anything wrong with using an oversized mppt charge controller with a battery ?

I am buying an oversized mppt charge controller for 2 reasons .
1) It is at a huge discount.
2) I plan to expand my setup in future so rather than buy a small one now, I thought I could buy the big one and use it with my small battery pending when I plan to use a huge battery bank.

Does this make sense ?
Thanks.

Thank you for your response, but what will the wattage of the solar panel be for this type of setup ?

If I was using a 30amp charge controller, I'd be using about 380watt panel for a 200ah battery.
But with a 50amp charge controller and 200ah battery, will the panel still be 380watt ?

If I use 600watt panel which is the maximum allowable input, will the mppt charger be able to limit the current going to the battery and if I use a 380watt panel with the 50amp charge controller, will it charge the battery at the same rate a 30amp cc will ?

Get the max PV possible, your 600w panel won't always generate 600w.....you can then set your mppt controller to charge at 30A

Please there's something I noticed.


Just of recent, my charge controller will be reading something like 13.2v


If I put on my laptop or plug phone, it will now drastically change to something like 10.2v

Later, it will start fluctuating between the two readings.


please what could be wrong.

this type of controllers are ultra cheap and prone to issues...no be 8k dem dey sell am so?. grin

if you can rule out the CC being the problem, check your solar panel or battery connections, either the connection is loose or the solar panel or battery is going bad

Hello, why comparing two mismatched brands

You don't compare Index brand with Gacia as one outrightly superceeds the other okay. Compare Gacia with other Chinese models .

We're always available as last resort for purchase if interested in any.

Index 200a .. 195,000 unit price . 190k "8 units above" "1 year warranty"
Gacia 200a .... 130,000 "6 months warranty "
Ritar 200a ..... 193,000 "1 year warranty "
Ritar 150a ..... 165,000 "1 year warranty "

I got my Cells (4 Replacement Cells) from the Alibaba Seller called Shenzen Dery New Energy Company.
I initially purchased 34 Units of 280Ah but four of them were damaged in transit, which is what the Seller, Selina Li, has just replaced.
The freight Forwarder she used this time around, did also not give us any issues as he responded promptly to our queries.

I am raising this here because l like to give Credit to those (Seller or Installer) who strive to do their chosen job, RESPONSIBLY and with INTEGRITY, for which a customer pays.

This Seller replaced the 4, 280Ah Cells, all the way from China, at "No Cost" to me (except the Dispatch delivery to my House) and to my surprise, even included a Letter of Apology and a beautiful, cuddly Souvenir Gift!
Just look at that! Imagine if all Sellers/Installers/Service providers exhibit this sort of attitude?

It shows Humility; it shows an intention to protect the Company's Name and Brand, at all cost; it shows Competence in their ability to deliver to the Clients expectation; it shows that the Seller Understands what is required to be done, to achieve Excellence, it shows the Seller Appreciates the Business of the Client, etc.

Now, tell me, why wont l recommend such Seller to anyone, putting my own integrity on the line?
Unlike one Service provider here who you give a job to and end-up causing damage that is worth twenty times in Cost, to the job you gave him!

The Replacement cells came well packaged and protected and they are top grade Cells.
Just so we know, this is a Chinese Seller on Alibaba, that l have never met (I read some negative comments about Chinese Sellers) while this incompetent and quack "Nigerian" installer is all over the thread showing his lack of integrity and competence.

Others who also had their purchase (in the Group Buy) delivered by the same Seller, will read this and attest to how their items were packaged.

I have attached pictures of mine, as proof.
If this Seller can go all out to replace a damaged product and apologize for it, then l am certain that your Money is in good hands, if you buy anything from Selina Li, Shenzen Dery New Energy Company

I am not denying there were leaks. Wen we had that issue way back, both parties came together to resolve this issue. This is as far back as 11 months. If he still has issues, cant he reach out to me and we discuss how to fix it as men. I don't run away from repairs. He didn't tell me anything until wen he made that post. Infact it was when he made that post I'm just knowing he has issues.

I will call him and send a roofer to access the damages.

Thanks for your input.


You keep lying in Public and it shows you have zero Credibility.
You told me you are a University Graduate, so it will be wrong of me, to assume you to know the meaning and import of those words l highlighted in your Post.

1) The Damage you caused to my Roof, by your Quackery and Incompetence, is more than just Leaks!
Leaks can be plugged but the Damage is majorly CRUSHED ROOFING SHEETS, caused by your CARELESS and INEXPERIENCED walking around, on my Roof, with FOUR other men.

2) You said you RESOLVED the issue when l contact you about it, in September or so?.
The question is: How does asking a Roofer to plug about some of the 15 leakages in my Roof, RESOLVE the issue of Crushed, Damaged Roofing Sheets?
How does that "plugging of some Leaks" back them, amount to a COMPLETE RESOLUTION of the Damage you caused with your quackery?

3) My Roofing sheets are still crushed as l type this, leading to secondary problems.
The only lasting Solution/Resolution is to REPLACE the AFFECTED Roofing Sheets (about 75% of the Roof Area, in the three locations you installed Panels, on the Roof).
So, when you say you have "resolved" the issue, l would ask: Did you replace the CRUSHED Roofing Sheets?
The answer is "NO", so what is all the noise you are making online?

I have asked a Roofer to assess the damage and the Roofer that told me the best solution is to remove the damage Roofing Sheets and replace them with New Ones. He added that the more we keep climbing the Roof to plug leakages (which keeps re-occurring within those crushed areas), the more damage we will have and the more leakages we will get!
That is obvious and reasonable, to any reasonable person.

I dont need another Roofer to climb and walk on my Roof (and potentially damage it even more), for any, additional "assessment", at this moment except to Replace the damaged Roofing Sheets. There is enough "pictorial evidence" of the situation of the Roof, which l have already provided.

Since you have been sounding-off, l can refer you to the Company that produced my Roofing Sheets, in the Dopemu area of Lagos, you can pay them for the Roofing Sheets, while l take delivery of them and ask the Roofer to remove the damaged ones and replace them with the New ones or l can buy it while you credit my Account for the Cost.

You can even pay for the "Accessories and Workmanship" but stop coming here to mouth-off that you have resolved the problem.

As far as l am concerned, [color=#990000]you @Zeestone99 / Mazine Group was asked to install Panels on my Roof but in the process, you damaged my Roof, through your Incompetence and Quackery[/color] ... and the damages are still there, for all to see.
