Is that why a 48v 200ah bank(10kw) should cost 1.2 million Naira? Meritsun 48v 200ah cost $1500 or 850k on alibaba. Is your battery better than meritsun?

Greedy Nigerians!

My 24v 5kw felicity battery is acting up.
It works well during the day but at night even without putting on a single bulb, it will go off. It's barely 2 years old.

I need a better recommendation of a 24v or lifepo4 ready made battery pack I can use for my system.

Up your budget so yo don't end up with mediocre set up.
My recommendations includes LFP battery, don't start with lead acid battery.

I blame @Masterdazhem for openly stating his budget here. Hopefully, he doesn't end up using someOne here as installer/suppliier because chances that they would help him spend more than that budget is very high.

once again, I constantly would keep on saying this, make una try dey avoid Lithium batteries. Even banks, Telecommunication masts, etc, companies that have deep pockets don't/rarely use Lithium batteries, YET una for Nairaland go dey TRY force am down the throat of those who don't know any better. Some of whom are evven struggling to buy 200AH batttery sef.

I have 20 pcs of 300-watts panels, use both MorningStar, and epEver MPPT chargeControllers, yet na common acid battery I dey use and have encountered NO issue.

Also, make Una dey try dey avoid Hybrid Inverters. The way dem dey spoil eh, no be here. Even the process of REPAIRs get k-Leg.

Can you give us the picture and let's see the particular model?
It works well during the day because the pv is giving the backup. Once the sun is off, the battery can't withstand the loads alone. I wish you were able to view individual cells performance.
Defective grade cells used in building the pack is the major suspect here but even at that, two years of usage is too short.
Abuse is usually brought under control via lvd either from the bms or the inverter. Dc circuit breaker if installed usually takes care of short circuit.
Two years of usage for lifepo4 battery is very bad. Lead acid battery is far better than it but one may think you bought fairly used one, probably the one with 2000 cycle life.
Sorry about the unfortunate situation!

Dam5reey:


He stated is budget for a 5KW set up.. if you don't have any suggestions to contribute stop quoting other person's opinion.

Air your own view.. instead of typing essay with nothing meaningful

Long before Solar became popular in Nigeria, I have built batttery packs out of need AND passion, hence know what it entails. Now a lot of people, who are in this line mostly for the money are cooking up al manner of things. Even laptop battery sef, a single cell could render the entire setup useless.
Now add quality of battery, among other things. What if they didn't weld the batteries well.

Even my next battery buy, I plan buying 2Volts, rather than 12-volts batteries. I still hhave no reason to go lithium foor numerous reasons one of which is stress of getting quality cells.

...annd the energy wey dem go take attend to you when you come back for servicing/complains, ain't no where the energy they used in confusing you to buy it in the first place.

so long it makes sense to me, that's all that really matters.

So with all your expertise, you were able to make recommendations to him, without having the slightest idea his load requirements.

microgiant:


Boss, see the This advert. for inverter



Then buy this panel from fouani //fouanistoredotcom/ng/en/product/jinko-475w-monofacial-solar-panel N148K X 3 #444,000

you get balance of #1,260,000 to buy battery if it is LIFEPO4 battery, you can add more later, also the panel you can add later

Due to your battery and panel capacity, you can only watch TV use energy saving bulbs like 5 and Rechargeable Fans, laptop and phone charging.

Can 2m set up your system?
How much is medium grade Lead Acid battery now? Most 5KVa and above inverters come as 48v ; so he will need 4 as minimum. And he should be ready to buy another set in 2-3 years depending on how much he cycles the battery.
I am aware that he can spend withing his budget and get a decent setup, but lithium battery afford future expansion and cater also for unpredictable usage and large power draw.
Little is better than nothing !!!
People should just learn the rules of whatever battery setup they settle for, otherwise

thought felicity say they have 5 yrs warranty?. why not take it back to them for warranty repairs. i suspect some cells inside are out of balance

bassdow:


Don't buy a readyMade battery pack. Most what's in Nigeria is composed of cheap lithium battteries, very very cheap PWM charge controller, laptopCharger, desktop PC fan, and funny paddings of carton and the likes.

Why not just buy as many solarr panels as you could afford, buy charge controller (PWM or MPPT) , buy battery, and be done with it. It's quite cheaper now and later.

Oh it's not like that. I mean ready made certified battery pack from a reputable company.

I have Felicity hybrid inverter and 2400w panels. It's just that my battery has gone bad. That's why I said I need recommendations for a good lithium or lifepo4 battery pack.

Moneyboyz:


I actually bought it brand New.
Used to work great in the past but now it's disappointing.
Is there a service center here in Lagos I can take it to? If yes I would love to take it there for inspection. If they can repair it, I will buy another pack to boost it to 10kw.

I share this school of thought...

While we are shouting embrace new technology, you will be surprised that some military technology are still based on the old methods...

Felicity is not and never has been a good brand: trustpilot[b]dort[/b]com/review/felicitysolar[b]dort[/b]com
If you want a good quality, ready made LifePo4 battery, go for Pylontech.

irrespective of what you end up buying, there's those that never/rarely loose, they're the DEALERs/SELLERs

OKAY

as for me, I tend to see nothing to change nor fix so long what I have isn't broken.

Sometimes, na when person dey find upGrade, e dey enter wahala. whyFixIfItAin'tBroken

if what you had earlier served you quite well, you ought to be looking for either same exact version, or a higher version from same company.

Also how long (in years) did your battery serve you ?
Is it out of warantee ?
Since you used hybrid inverter, are you sure it ain't the charging system that weakened it ? BMS fit smart no mean say dem no dey 4ckUp

Moneyboyz:


Battery is still in warranty, I've only used it for a year and 6 months or so.

During the day I use it with all appliances from overn to freezer to ac to pumping machine and washing machine.

At night it goes off before 2am even when I only have 1 bulb on or none at all. Sometimes it won't go off at all and have like 70 percent in the morning on same 1 bulb.

I don't even have the receipt so I'm not sure they will be willing to fix it or anything.

hmmmmmmm
