That's d recommended discharge per hr. They charge faster though, most likely 40-60a/hr charging current.

ojeysky:


1/20 which gives you 0.05 and then you multiply that by the battery capacity which is 11A. I would have followed this up with a few lithium campaign but make I no talk

Valto

zinodizt:
Can you recommend any vendor here for that?

There is no info on d charging current. It only state that u should discharge d 220a in 20hrs. That's 11a/h

osayuwamwen:
Pls what is the maximum charging current of this luminous 220ah battery, the battery information is written on the picture below

If u av d money, go for lifepo4

I have two 250w solar panels and 1kva inverter and a battery but the battery is currently bad and I am planning on replacing the battery. Which Battery would be recommended as I am using just one I am looking for a strong battery and moreso can I add a panel to the setup...

1. Wat kind of panels, can u snap d nameplate
2. Were dey connected in series or parallel.
3. Where are d panels facing
4. Y did u decide to go for Felicity battery, u could av gone with coupled cells if u read through their reviews on this thread.

emmy9500:
Finally installed my solar system, thanks to all the information in this group

I have a question, I have 3 panel rated 380W but my charge controller only read 340-400W the installer said it would have been higher if I used 200W panel, I am planning to add another 380W solar…. I just want to ask if the reading from the charge controller is normal

The battery can fast charge I guess. But the discharge was rate was clearly stated 0.1c

ojeysky:


Well it also means 95A and below is fine. That said using the recommended 65A that is almost 0.3C. Seem high for a lead acid that wants to last long

I think wat that means is 95a n above will damage d battery. Safe charging amps is 35-65a as written on the battery.

ojeysky:


The charge current text on the battery is blur can you indicate what is written there as it seem maximum is 95A which is quite strange to me for a lead acid

This discharge rating is quite low. It's states 200a discharge is 20hrs that's 0.1c or 10% of the capacity in 1hr. Probably that's just a paper something. Cause batteries like fullriver should be able to handle atleast 30% or 0.3c eg a discharge of 60a of dat 200a in 1 hr. It's not like I av fullriver batteries but I av 2 quanta SLA n dey do 30% of capacity discharge. Well. It best you stick to wat u av on the battery. So as not to kill it b4 it time

Milito:


What is C rating please?

Any clue from the attached pic?

You will need 2 of those if your panel is above1400w

emmy9500:
Is this type of charge controller suitable to charge a 5kw/24V lithium battery

Since u can't open the inverter yourself. It's advisable you take it to inverter repair center. N one of your battery is bad already. My guess is you don't do 50% DOD.

Good day solar gurus. Please i noticed of recent that my solar battery (two 12v200AH) after showing fully charged at 100% will suddenly start dropping down to around 70% by evening even when the solar system is off. As such, it doesn't last whenever I start using it. Please what could be the problem? I am using a 2000va/24v smarten inverter. The batteries are not up to a year & it was serving me very well before now. I also noticed the small fan at the back of the inverter is not turning & it also shows Mains not available

There are lots of videos on YouTube you need to watch and articles u need to read for you to understand things.
V-volt
A- amp
Ah- ah
W- watt
Wh- wh
U see those LA battery u dey see 200ah. It's 200a. Dey are not 200ah. 200ah means d battery can do 200a in 1 hr. Check basic electricity videos on YouTube. Read article on electricity and DC applications. All these will b made clear

ojtech8291:
I don't understand what you are stating here as a unit of battery. Unit of battery is AH. When you multiply V by AH you have VAH. Note that VA= W, so you have WH, When in 1000 up wards it becomes KWH for battery. Without the H there you are still not referring to battery.

Yes you can. But if ur choice of battery is a 12v Lead acid, don't do more than d c rating inside d batteries manual or on d body. If your going for lifepo4. Ur battery can safely go as high as 1c. But that doesn't mean you should load ur inverter pass 60-70% of it's actual capacity. U will break it in no time.

Milito:
Hello gurus,

Is it okay to use 4units of 200ah batteries with a 7.5KVA inverter?

Works on most phone. We get Tecno, Infinix, Redmi n Samsung here. N it works on all. If d one on playstore no work download from their website.

isangjohnson:

What type of Android phone will work with this App Sir?
From what I've noticed, not all Android phone work with it because it doesn't work with Tecno pova. Download and open for the first time and refuse to open subsequently unless I uninstall and install again.

W=V*A
12v*220a=10,560w or 10.56kw
Note that cause u physical have 4 12v batteries doesn't mean you have 10kwh as most lead acid is rated 0.3-0.6c which means ur 10kw battery can safely pull 3-6kwh out of the 10kw you have on ground.
Kw- kilowatt
Kwh- kilowatt hour

Milito:


Please how is this calculated?

Wat kind of panels, are they new?
Wat kind of battery, are they new?
Wat kind of inverter
Ur charge controller amps is too small, b it pwm or mppt, so u don't av a charge controller.

damianking1:
I have a 3pcs 306watts solar panel

Please what can this batteries carry and how long can it be used.

E gree 65k?

In need of 5/6kg cylinder. Kindly quote if u av within Lagos/ibadan

Ur panels is facing north? Place them on the other side of the roof den.

osayuwamwen:
Yes it's a 12v system, am using choice solar panels

He's green 🍏. You can proceed

Kabawhat:



Good evening house am trying to buy PowMr 60 Ah MPPT solar controller from this my OGA =odimbannamdi and making an upfront payment


Abegi who has done business with him in the past ooooh

When u get the type of cable used. If it's a DC cable...10mm.. den u can cancel out cable aspect. Next is to the amps generated by each panel n d type of connected don for them. The panels might b those used panels sold as new.
They might series all those panels. Given the fact that the CC can take up to 500vdc. But if those panels are not generating enough amps each. The high volts will just b figure head.

Elcapitan0:

We will find out on cable size and specifications used and communicate. The orientation was not so bad as it was installed on an flat roof. I'll try upload a pics for further clarification.
P.S The sun rises from the other end of the roof and sets on the side of the roof where the panels are.

100k? For wat exactly. This shows you didn't even take any moment to read few pages back. Ur budget can't buy any decent battery alone, talkless of other components. Kindly read some pages back to know prices of items needed.

wayisshut:


I am looking @ at budget between 80- 100k

Sunking can power 5 cctv for 5hrs... Neva
How much is ur budget for d setup fess

wayisshut:
hello my people. I am looking for a very cost effective way to hook up a small solar system to power only a cctv setup. Just 5 cctv cameras, a router, dvr , power plug. for about 5 to 7 hrs during the day. not totally offgrid anyway sometimes our "NEPA" is available. Can sunking power box suffice?

Enter Jiji n check for different inverter prices. Message dem to confirm price.
There are few of principles I can't begin to explain inorder to answer this oda question. But I'll say this. if u will use 400w panel go for yingli. It's 120k or so. Mppt CC ofcourse

ianian:
I want to upgrade my 12v system to 24v as I wanna add a solar setup to help PHCN charging. I already have 2 X 220ah batteries.

I need help, I need know the price range of an afriipower 2.5kva 24v

I read somewhere here that 2 pieces of 400watts panel is preferred to 4 pieces of 200watts. (What is the cost of one 400watts panel please)

Lastly, do you advice a pwm or mppt for this setup. Thanks

E should not add any panel. Best is for him to bring those panels down n test them one after d other.. something is wrong somewhere. It's either the panels orientation is poor or some of d panels are bad or cable problem.

Elcapitan0:
Hello guys. Please i have an issuei need your expertiseon. My friend have a 5kva 48v felicity hybrid inverter with 8 400w panel. The problem he is encountering is that most times, the panels does not fully charge on a well sunny day as the maximum he ever got was 800w showing with not too serious usage . He is of the opinion adding more panels which I told him to hold on for now. On the spec sheet of his inverter, i saw max solar voltage to be 145V and i saw an 'off grid' hybrid 5kva felicity inverter with 500V max solar voltage.
(Don't know if they are different). Please guys what can be done?
The last pics was the off geid inverter i saw

I won't advice u buy used imported panels..

Kabawhat:
Is this deal worth it


Solar panels US used not brand new 180 watts

Mono 38k
Poly 35

U should be less concerned with the peak power as this is d surge rating. Continuous draw is all that matters. Don't go above 900w as advised.

osayuwamwen:
They wrote 4.5kva as peak power

Lol

mctfopt:


At least the installed used trunk. The things I've seen where the installation looks like olden days NITEL cable lines

His work no neat at all. Especially the way e placed the PVC Trunks.

osayuwamwen:
No installer

Ur setup is ok for starter. Did u do all that ursef?

osayuwamwen:
Thought they said mppt controller are better, am using 60a Felicity controller
