essegis:


Well done sir adrusa.

I just got myself 2# 100A Felicity charge controllers but trying to program them for lithium batteries is presently proving difficult.

I wanted to adjust the float and absorption to 57v but it seems the charge controllers can't go beyond 54.6v. Actually they get the battery pack to this voltage and stay there for the remainder of the day so I'm experiencing a lot of waste in that direction.

Anyway this can be adjusted upwards?

Use the user manual.
Or press hold the button, when esc appears, move one step press hold again to change the battery type to lithium, then you can adjust your Charge and flood voltage

If you can collect your air-conditioning water without any debris and dirt. You have distilled water. You can also run the water through a filter.
I know someone that uses well water for their tubular, I won't recommend it. The person also uses a tds to ensure the water is ok.

I use the ac water for my tubular, stopped buying distilled water a long time ago . Get a tds also.

My brother, the first option you gave can be used if the AC pipe is kept from contact with dust etc. But the second option is no go area because no matter how you filter water can not remove dissolve element that will react with your battery. Distillation and filtration are two different separation techniques which are used for different purposes.

PowMr 60A (12 - 48v) mppt variant.
@dishtech thank you so much for responses, I believe the points you bulletined are the reasons my CC is still accommodating my using the 24v panels out in parallel to charge the 12v battery through the PowMr.
My panels are facing south but a angle around 30⁰, while charging and using the battery to power the house simultaneously the highest av noticed on the CC is 45A at 14v.
Hope this is fair from the whole system?

That means the maximum you generate at peak is around 630watt. If you reduce your tilt angle you will notice an improvement. But be careful not to burn your charge controller. At your present degree it will only favour summer and equinox, but very poor during winter. I.e 30°-8°=22° off. A good installation and all condition conditions being met should have highest generation in March and September when the sun will be almost perpendicular to our centre of head at noon. But with little reduction by June and December.

bbally:
Note that every charge controller has a maximum solar power it can accommodate. Since your charge is 60A at 12v system you will need not more than 750w panels.

I have a 12volt lifepo4 with 12v inverter and 6pcs of 250watts panels connected in parallel. I was thinking of changing the connection to 2s3p until I read your comment. The present final output from my panel is around 40v and 35v at my CC which charge my battery to 14.5v. will it spoil my CC if I change the panels configuration ?

I have used the Powmr you mentioned, if the solar generation is more than the charge controller, the output will be going off and on.
If your installation is not efficient, it can accommodate it. That is;
1. If your panel is not tier1 or new.
2. If your installation position and tilt angle is off angle.
3. If your cable size and distance is wrong.
If the above is not met, you can escape the damage or else you need another 60A charge controller to divide the panels into two.
For you to know what you are generating, let your battery deeply discharge, if your panel is facing south, check and start changing by 11am and see what you are going to be getting between 11am and 12am on the charge controller.
Average tilt angle in our latitude should be between 6°and 15°, with 15° deference in summer and winter.

Obnoxious2001:


It's performance is okay on 2s2p.

Thanks for your input.
I appreciate

Also check your panel position and tilt angle.
Best position is due south and angel equal to your latitude.

Obnoxious2001:
I think felicity charge controller are over hyped.

The performance is poor.

4* 250w panel (voc 36v) and I can not get up-to 35A -40A....

Am considering reconfiguring the panel to 2s2p as against 4p.....

Please share your thoughts.

Check your installation. Also what is your battery system voltage. It's recommended that when using mppt charge controller, your solar panels input voltage should be at least twice battery voltage and above. So 36v VOC panels should be 2s2p

bbally:


So, a mppt charge controller cannot convert the 48v to 12v for better charge and carry more load without depleting the battery percentage.

Don't get me wrong! I said your initial 48v system configuration can be used to charge the battery if;
1. The total wattage of your system is not more than 750watt since your charge controller is 60A

There are two different things! you misunderstood!
He was asking about configuration of 8 pieces of 380watt panels totalling 3040watts on a 100A Felicity charge controller with the inscription 195V Max. VOC. Which I advised that he should get 380w to be able to configure 3s3p if his battery system is 48v, but if his battery system is 24 will reduce his panels by one to configure 3s2p or 2s3p.
Note that every charge controller has a maximum solar power it can accommodate. Since your charge is 60A at 12v system you will need not more than 750w panels.

bbally:

At 12v the maximum solar panels used should not be more than 1200watts.
So if your battery system 48v I will advice you buy one more panel to make it 3s3p, if the system is 24v or12v your panel is more than the capacity of your charge controller if properly installed.

Please, does this means that a panel array in 48v connection CANNOT BE USE TO CHARGE A 12V system with a POWMR 60A for instance

If the system was for 48v and the panels total watts is more than 750watts at good installation and optimal generation it will affect your charge controller

TechGeek777:


The (Voc): 41.30V.
Full Specs ==>
Maximum Power(Pmax): 380W
Maximum Power Voltage (Vmp): 34.74V
Maximum Power Current (Imp): 10.94A
Open-circuit Voltage (Voc): 41.30V
Short-circuit Current (Isc): 11.68A

On the other hand there's a 100A Felicity CC with below details,
Max Pv Input Voltage = 195V
PV Array MPPT Vol Range = 160-170V

My question now is, can Felicity 100A with above spec take the 8 panels using 4s2p config?

Or should I use Techfine 60A/80A with (Max PV Voltage: 150V) and go for 9 panels using 3s3p config?

Please I need the one that will produce optimally so I know the total number of panels to purchase and the exact CC to go for.

Forget about the 195v written on the Felicity charge controller. Don't give it input voltage more than 125v or else it will bring out fault light at every peak generation.
Since your VOC is 41.30v so I recommend 3s i.e 3x41.3= 123.9v.
Also since your charge controller is 100A,
At 48v the maximum solar panels used should not be more than 4800watts,
At 24v the maximum solar panels used should not be more than 2400watts.
At 12v the maximum solar panels used should not be more than 1200watts.
So if your battery system 48v I will advice you buy one more panel to make it 3s3p, if the system is 24v or12v your panel is more than the capacity of your charge controller if properly installed.

temi4fash:
Please i have a 2KVA 24V Genus Proton Inverter, I noticed it stopped charging my batteries up to 26V - 27V, At some point it would not go beyond 25V. Now it does not even charge the batteries at all. It comes on but just shows overload trip even with no load on it.

I use 2 nos of 200A 12V Gel deep cycle batteries

Can the inverter be repaired?
Can any one help recommend some one who can?
I also want to install 4 nos of 300W solar Panels, Any ideas what i need to look out for?

Thank you very much for the knowledge sharing here

Sorry am just seeing this post now! Has it been fixed? I can fix it.

isangjohnson:

Do you sale all at once or any number needed?
I would've loved to pick two.
How long has he used the batteries?

I will sale as individual can buy. The battery was installed December last year, that is one year.

It was replaced by 40kwh LiFeO4

Eight ( pieces of fairly used 200AH quanta battery for sale at Abuja for 65k. It can be returned for full refund if not satisfied with performance after one week. Reason for selling is because the owner want to replace with higher capacity lithium battery. Contact: 080-6765-two-six-39.

Is there any one in Abuja that has this light? I need 8pcs Urgently please.

Good morning all, who has 32s120A Daly BMS

Good morning @All please who sale 96v lithium battery or 48v that can be serries here?

Valto:
if u believe they coupled 16pcs of real grade A 300ah cells, with nice box and good bms, and still sell it for 1.5m,then u can believe anything

Bros take it easy just sell your products. Real grade is Eva grade the best? I think they have improved on their capacity even though it's not up to yet.

coldcandy:


I can see Felicity lithium battery.
People here said they are not honest with their spec ooo....

Yes their spec are always over rated, the 10kva maybe 8kva in actual, the 15kwh battery be around 12.5-13kwh in actual

15kwh lithium battery, 10kva inverter, 120A charge controller, 4770w solar panels installed at Katampe Abuja.

Penuelseun:
Oga lithium battery has two charge settings, bulk which is CC-CV and float which comes up when your battery is fully charged. Leaving your lithium battery in a high state of charge always is detrimental to the health of your battery in the long run

Bros when you select lithium battery mode on charge controller it's automatically selects absorption and float take it or leave it am not here to argue.

Penuelseun:
Absorb should be 13.8v while float should be 13.6v, you can contact their office, they should be able to set the inverter for you before shipping

Lithium battery does not have settings for absorption and float, it just one setting, if it is pwm set both settings the same but most mppt has direct setting for lithium battery

saint2ace:


Sorry if I sounded "harsh" in my response, that was not the intent.
On ur other comments, your points are duly noted..... Cheers

Cheers

saint2ace:


Bros you go wear glasses oh, all the cells I see are same specd, the difference being that he wrapped some cells in insulation tape thus the colour differentials.

On the issue of cell explosion, I believe u're over reacting, there are 2 variables that might lead to that, one being abuse or puncture to the cells themselves thereby causing a short, the second and also relevant to your observation being overcharge. On the first, most builds I've seen are isolated and non mobile, so hardware rupture is eliminated, on the second; a controlled charging source solves that problem especially since amp draw from the cells are at a very low C-rate........

Why using a kind of hash word on me? You would have bought the glasses for me!
Ask the person that own the battery to confirm their capacities before making the above comments
Second battery explosion results from over charge as you have alluded to, two battery of different capacities causes imbalance in the charging hence, one cells voltage will reach it maximum charge voltage before the other which can lead to explosion. Also the cell with lower capacity can get to it's minimum voltage when drained before the other hence can lead to premature death of that cell.

dollarnaira:

Unpack all and run a group of 3 sets.
Charge each set full(balance), allow dem to rest for few weeks to check for voltage drop then connect dem as 3s. You will enjoy it well.
The challenge is how to get a charger that can do 4.2v.

Time bomb below

The batteries am seeing has two different capacities rating of 2600mah 2000mah if both cells are of the same health condition will not Ballance hence can lead to explosion or fire hazards.

Moneyboyz:
Top BMS, has anyone used it around here?
Hopefully it balances this battery.

Long time! Did you solder the cells because it's as if the wire linking the cells has different resistance hence you are seeing cell "6" lagging behind, though your BMS has average balancing current, did you balance charge the individual cells before assembling? If no, try to charge cell "6" to push the voltage closer.

oldienavie:
Hi everyone, I want to setup a solar charging station for phone power banks.
Something cheap decent and straightforward.
This setup is only going to be used for charging power banks so I only need a usb 3.0 output and nothing else.

I did some researching already and this is what I think it will require, kindly feel free to correct me.

1 solar panel ===> Charge controller ==> usb 3.0 ==> power bank.

I dont know what these ratings should be
Can some one validate this and provide cost estimates as well.

Thank you all.

It's either you are going to use
1. 6volt solar panels or
2. Solar panel --charger controller --battery---12v/5v charger----powerbank or
3. Solar panels---- buck converter----- power bank.
I hope the power bank is a 5v power bank?

Good evening house.
Is there any professional installer in Abuja on this forum?
Pls I need one urgently, kindly drop your digit.

codeME:
hello,
What will 300k be able to setup if i have a working old PRAG 2KVA - 24Volts. Location Abuja. Needed vey urgently.
and what type of battery are now best for solar/inverters?
Advice needed.
Thanks.

1. 300k will give you 2 tubular battery at 250k or 260k. To be charged with Grid supplies (NEPA)
Or if you can up your budget by 235k will give you ;
Batteries X 2, 600w or 640w solar panels( though not sufficient but at least for a start), 60A charge controller and cables for the installation.
2. Best batteries are lithium batteries but mostly expensive at the initial cost but pays in the long run.
Am in Abuja. 080-676526-three, nine.

durodee:
Good evening house. Is there a way to repair broken panels? There is a project ongoing somewhere and I noticed as the panels were being offloaded that some panels had broken glasses. Is there any way the could still be useful? They are 450w panels and quite a number of them.
I am wondering if one can cover with new glass and seal the edges to prevent egress of water if that will work?
Just thinking ........

I can repair it for you if you are living Abuja.

abbeymighty:
Hello house, please what is the difference between using one 12v tubular bat3 and two 12v tubular bat3 in parallel?. Also two 12v tubular bat3 in series to make it 24v.
Thanks in anticipation for your response

1. 1+1>1, that is 2 bat3 gives you more energy for use.
2. Energy in bat3 parallel is equal to energy for bat3 in series.
If you have 12v Inverter and 12v panels (150w or 180w) with pwm charge controller or mppt with any type of panels go with 12v parallel connection,
But if you have 24v Inverter with solar panels above 24v ( 250w and above) with pwm charge controller, go for series connection.
Every type of connection has their pros and cons.
Also basic use Inverter like 1kva and below uses 12v.

Kingdemu:
What's the average lifespan of a solar panel pls?

25yrs.
