Juror:
Thanks for your contribution as always. I need some clarification.
I believe generally, charging each battery in it's isolated state with a 12V charger is normal but based on your experience and what you've practically done, do you attach the 12V charger to each battery's terminal without disconnecting them from the string?

Also, do you switch off solar charging for them while doing so or the solar charging continues while the individual chargers also charge the batteries while being powered from the grid or Gen?

Are you saying that all these used panels sold in alaba and oshodi are not okay?
I just bought 6 200w penels today, I hope I won't regret this.

I didn't mention Alaba or Oshodi.
If you know your way around Alaba, you'll get decent and even top grade products. A couple of the good brands have offices around there too.

A short review: A low budget value for money. Need an MPPT CC with the most basic Interface but keeps working? Then get this!! PowMrI have 3 of them in use. Works well , relatively cheap and can work for 12,24,36 or 48v systems. Works with Lithium batteries and
lead acids variants. Excellent as a back up CC too in case you need one to fall back on. Planning on getting another one soon.
Cons? Plenty !
1) No log Interface to record daily harvests , so difficult to know exactly how much you are harvesting daily. I have to rely on other ways to get this.
2) Connect points are a bit small and take max of 6mm cables
3) the supplied screws to attach the CC to the wall sometimes are too small
4) Price is getting high nowadays

Powmr is quite dependable but always try to confirm that the display voltage matches the output, sometimes they're usually off by few units.

For the old powmr, you can use 10mm, split it and connect to each of the dual terminals.

The new model's terminal should take 10mm with ease.

NiyiOmoIyunade:
Felicity have a decent 1.5Kva 12v and 2.5Kva 12v inverter.

Do you have any personal experience with these new felicity inverters especially the non hybrid types?
I've been longing to know their idle draw because I'm not sure if the transformer is iron core or toroidal (I saw a picture of it but wasn't sufficient to know).

Anyone has a personal experience should also share, thanks.

NiyiOmoIyunade:
so the only way to achieve good results is dedicate a 12v charger to each 12v battery string and let them do a thorough battery charge - whether you are equalizing flooded battery or 'controlled overcharging' GEL or AGM, this is the way to go - battery maintenance is best done at the single battery level and not in series.

The question then comes what to do with 2v and 6v standalone batteries. I have left that to the more vibrant new generation of enthusiasts to figure out

earthrealm:
10kva inverter is a no no for just 4 pieces of 12volts x 200ah batteries.
Any installer who gave you that option needs to be shot @ sunset...and shot again @ sunrise if still found moving...

Its your proposed load that will determine the size of inverter you buy.
Those inverter you posted, hope you know they usually have a high idle consumption.the bigger the inverter kva, the bigger the idle consumption.
Most.hybrids hv lower idle consumption

Are really you sure those icellpower inverters have high idle consumption?

TechGeek777:
Please guys which among the below 300W Solar Panel can Max out close to it Wattage and that can also perform well even in this endless raining season?

Auxano
Felicity
Flame
SunPower
Rubitech

Kindly help arrange the above panels base on the one that performs optimally on a scale of 1 - 5

Don't touch Rubitec panels. DON'T

olopan:
Vmpower has editable options but I will find through the manual and revert back to you soon

It is an hybrid
30A PWM controller and also transformerless

is it transformer based?
Can the voltage settings be adjusted or it just has option of choosing preset voltages ?

sharks776:
I installed 1 wakatek 5kw battery and later added another after 3 weeks. The 2 are in parallel. The last one I installed is making a kind of fuming noise when charging with grid from my Felicity inverter. So I checked the charger amps which was set at 40a. I reduced it to 30a but could still hear the fuming sound from battery number 2. I had to reduce all the way to 10a b4 it became quiet.

Pls does anyone know the right charge AC charging points for this batteries.
For now am only charging from PV.

Aren't they lithium batteries ?
Maybe the voltage setting is higher than required.

sharks776:
That is the exact type of inverter

Ok, do you know the idle consumption/no load consumption? Have you measured it?
Please I would like to know.

olopan:
Can anyone check and see what's wrong in this installation picture?

DC breaker polarity wasn't adhered to.

olopan:
Okay! Please make me understand.

It implies extra or premium features.

sethtsadopp:
@ Olopan

Do you have alot of experience working with Deye inverter? I mean have you done several installations where you used the Deye?

Several installations using Deye ? That may be a tall order.
Is there anything peculiar with Deye that inspires such criteria?

toluxa1:
Unless there was an update few days ago. GTB limit is $100/$ as far as I know.

It exceeds most times? Especially close to the month end.

Jefferyzz:
It works on AliExpress and ebay. Avnt tried Alibaba

You use it directly on eBay or via PayPal ?

earthrealm:
Dont drain ur leadacid battery below 50% , dont leave it always partially discharged, it likes being charged full daily + dont load or charge it above 15 %, ie not more than 30amps or above 300 watts load for a single 12 volts 200 ah battery.then a good leadacid can give you 800 cycles..

Lithium battery doesnt care for any of the rules above and has 4000 cycles, before loosing 20 percent capacity.

From the above, u can see why leadacid will always disappoint, as its tough to give it what it likes

You just set out to destroy lead acid from your first character till conclusion of the post... lol

sharks776:
Hello everyone and professionals in this thread. Am having a problem with my setup and need help

My equipment
CC - Fangpusun 60a
Inverter - Felicity ivps3524 combined with charger
Battery - 2 wakatek 5kw lithium in parallel

Problem:
Both cc and inverter are set to charge at
Abs 28.8v
Flt 28.8v

However, during the day whenever the cc reads 28.8v, the bms of the battery will read 26.7v at most. This shows a difference of 1.1v in charging.

During the night, when the inverter is charging via grid and reads 28.8v the bms of the battery will be 27.3 or 4 max
I am thinking of going with the bms reading and adding at least 1v to the cc and inverter charger setting. I also came across this on YouTube

https://youtube.com/clip/UgkxoY4QXwrIJw9Va7P_grNiSQdZuhwT66at

Help me pls, I really don't want to fry this new expensive batteries

Use a trusted multimeter to take readings and compare with the bms. I'll suggest you trust the BMS more.

What brand is your CC ?
is the felicity inverter the same as the one in the attached picture?

FireTheSun:
I want to believe you have your reasons for identifying yourself as the Installer. If you did not, you can bet l wont, it is not my style of correcting someone. But you have, so that burden is no longer on me.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Now, I will MENTION and EXPLAIN a few things:

- How can you say: "we did a fine install but you had leaks"? (in the Roof, after your work)
Are Leakages in the Roof, (when l did not have them before you came to install), part of this "fine install"?

- How can l confirm to you that "we are good", when it has not rained, after the effort of the person you sent, and when you asked?
I confirmed to you that he came and did his job, "hopefully" the leakage would have been rectified, but that can only be determined after it rains again!

Yes, we had Leaks, even after his effort . Not because he did not do a good Job but because he can only do as much!
He was able to block some visible Nail holes but the damage was varied and widespread

The Roofer you sent tried his best (you should have brought along this Roofer with you, when you came to do the installation) but "Squashed" Aluminum Steptiles Roofing Sheets are impossible to be straightened up again after crushing it by walking on them without due care, anyone who had seen Steptiles Aluminum Roofing Sheets, knows this. We had Leakages from various Nail points as well..
I was "shocked" since that was my first experience of a Leaking Roof ( and angry" as well), though internally, l was blaming myself, for the choice l made.
I just decided to "learn the lessons" and concentrate effort to rectify the problem, as quickly as possible.

The "other side" could not have been repaired, when the Roofer you sent came to do the repair because, as of that moment, l never knew there were leaks on that side too (My Tenant was not around during that period when you installed the Panels on his side).

I did not say the "repairs" will cost over #2M.
What l said was that l will have to replace the Roofing Sheets with new ones, at over #2Million.
Replacement => Put in fresh Roofing sheets.
Repair => Call Roofer to be looking for Holes to plug.

But he cant push-back-out and straighten all the depressions caused by your Legs marching (carelessly) on the Steptile Aluminum Roofing Sheets, can he?.
Somethings, when damaged, can never go back to their original form, even after repair. What you do is replace them, if you want to go back to your initial state before the damage.
That is current state of the problem now.

When it rains, depending on the intensity of the rain, those "Foot Depressions" act like BOWLS, they store rain water and then when full, the Water overflows in a direction of least resistance, without following the grooves, (as it would have done in an undamaged Roofing Sheet) which can be anywhere on the roof!
Roofing sheets on a Roof are meant to have smooth grooves and slanted in a particular direction so that water flows down as it drops on it, without accumulating in "big depressions" created by squashing of 10 People's feet walking on the Roof .....without a care or as if it is made of Wood! I explained all these to you back then. I took pictures and sent them to you.

The Roofer you sent did try to "push-back-out" some of these Squashed Depressions on the Steptile Roofing Sheets, (from inside the Ceiling) but in most cases, they only got worse because Steptile Roofing Sheet are not supposed to be pushed in and out, due to the designs on them and the Depressions were just too many.

l am the sort of person that likes inconveniencing people, including my tenant, with a leaking Roof.
How does someone pay me premium Money for a House and he has to be collecting water in his Bedroom, Kitchen, etc, because the House Owner installed Solar Panels?
What l wont take, l wont do to others and l have promised him that once l am back in the country from my Travels, l will replace All the Roofing Sheets in that area that were depressed with your feet and leaking, with new ones.
By my estimate, it will cost over #2Million to complete the job. That is what l wrote.
If your intention is to contest the amount, then go and find out how much they sell a length of 0.55 gauge Aluminum Steptile Roofing sheet and multiply by how many will cover the area, (add accessories like Nails, Flyband, rent Ladder, etc to it and include workmanship).
Add the cost of damaged, suspended Ceilings to it (areas where the Water leaked unto the suspended Ceilings and they buckled, after getting soaked)

But l am sure you would have learned some lessons from that job, which is the crucial thing.

- Like not having too many people on the Roof, at the same time. Just the minimum required.
At that time you were doing my Installation, you had yourself and four other guys on my Roof a few times though most times, you were on the ground.! It was as if my Roof was being used as a 'teaching experiment'.
As you guys were working and walking around on the Roof, l could hear the sound of "Crushing of the Roofing Sheet", with each Step taken, as they were walking on it!
I am sure you remember how l was raising the Alarm that you guys will damage this Roof? The Crushing sound was so evident from inside the House! You kept assuring me nothing will happen and l believed you, against my instincts.
I want to believe such wont happen in the future, when you install for others.
Experienced Installers should know how to delicately walk on the Roof without Squashing the Aluminum Steptile Roofing Sheet, those things are kind of fragile.

Like l said, another installer (just Three people, only Two were on the Roof, One was Down) recently installed additional Five Panels (655W each) earlier this year, all the area he worked on, not a single leak and the rain has been brutal this year, so it is not about the material or style of Roof, it is just "inexperienced" Workmanship.

Remember you told me l have to buy another Inverter, if l were to add those New, Five Panels?
Well, we did not have to buy any other Inverter, the New Installer l engaged just re-arranged the whole configuration and it is pumping out Power mercilessly..
We are completely off-grid in the last four Months-plus and Electric Cooker, Washing Machine, Submersible Pumps, Freezers and all other Home appliances are under normal use, though we do stagger and Submersible Pump not to run around 2pm only.
Why did l mention this? It appears there is a "knowledge gap", when you told me l cant add those New Panels to the existing ones, unless l buy a Second Inverter (which l would have done, if you came that day as l had called Gennextechnologies office immediately).
You said you needed to run them New Panels separately on a separate Inverter, for them to work.
As God will have it, l did not have to buy another Inverter.

My aim, in not mentioning the identity of the Installer (which drew the ire of some people here), is to mention the problem so the installer or anyone in such position, can learn from such mistakes, without damaging the image or brand of such offending Installer. I have No Apology for that decision, that is who l am

I never raised the issue here, until l was "wowed" by the Installation of that many panels by @Chris and even at that, l still kept your identity PRIVATE, with someone abusing me over it!. Having worked for me and our discussions about 'Unilag', you obviously knew, as an elderly person, exercising control over one's anger, even when l feel offended, is not unusual, would l ask you to come and replace the Roof that was damaged? (I remember explaining the issue of "vicarious liability" to you, on phone)
Being Vindictive, is not one of my attributes moreover, l passed those stages, a long time ago, l dont know who my own grown-up children will meet, in far flung places.

I hope this brings Closure to the whole matter, now that the Installer has identified himself.

I perfectly understand your perspective and share some of your views and suggestions too.
I believe the Aluminium's streptile profile too complicated things, it's one of the many factors that should be considered. Installation environments would always differ, adaptation is important.

samnaija:
Thanks for the enlightenment , it is an eye opener. Two sides to a story. It takes a true professional to speak out. You even paid for the repairs you try..

I can attest that zeestone99 takes care of issues or tries to compensate when issues arise, with products.

earthrealm:
get a 12v 200ah to 280ah lithium battery for about 300k to 400k abd forget about buying battery for the next 10 to 15yrs. or get a 100ah model for less than 200k if funds is a constraint
@valto advertised some units a while ago

Calm down with Lithium evangelism, at least understand his system before throwing in any solution.

dbshaywhy:
Good evening professionals in the house, my 1 year old deep cycle inverter battery is totally down, as confirmed by a technician yesterday morning...

Am now contemplating either i buy a new generator instead of another inverter battery that won't last more than a year, but still, am considering the economical aspect of the inverter system...

Please, your heartful advice will be highly appreciated.

Give more details about your system, panel configuration, load profile/appliances in use and period etc.

ebocoms:
Good day Everyone,

Please I need review in making decision on the following Solar Panel brands. Which is durable and have better yield:

a. JA Solar

b. ERA

c. Jinko

Thank you.

I can confirm JA Solar and Jinko.
On different installations and they give optimum harvest.

durodee:
Obviously nothing in life is perfect.
I have been using Gennex products for about 6 years now. I have both the 3.4kva and 5kva Hybrid. The 5kva was just commissioned in February 2021 in another facility and working well. However, the earlier 3.4kva has been beleaguered with repair needs and despite two visits back to Gennex ( lasting months each time before I could get my inverter back and about 100k spent on logistics and repair costs) it's presently down again after working for only 4 months or so after last repair. Total active service less than 3 years.
I am just tired of the inverter sef. Always board issues.
The same load I was using it for, a 2kva Prag and a 2.5kva Felicity (transformer models) have both carried it without stress at different times.
Presently, it's the 2kva Prag holding forth

Is the felicity inverter you're referring to, the IVPS model? The type in the picture I attached to this reply? Do you know it's idle/no load consumption?

Anybody have experience with this felicity inverter and it's idle/no load consumption?

Hello house,

I purchased a PowMr 60A MPPT CC barely two months ago for my parents setup, unfortunately they called me that the display stopped working and they are not able to ascertain if the batteries are charging. Their installer also travelled so he hasnt been able to go take a look. Please any advice on what to do? Or anyone experience such? Thanks

Had similar experience, the CC was actually still charging but client required visibility so I had to sort out the client with a new CC, I'm expecting a replacement LCD to replace the bad one, hopefully it works.

Am not even sure dat gionee has carlcare center in ibandan

There are also rumors that Tecno P5 lags so what da heck?! both are 512mb so its expected. The main thing is how to manage 'em
