BlueStripper:
Good Morning Everyone,

My apologies for the confusion. I was so angry yesterday.

I have an independent lithium setup that's different from the lead acid setup. Each setup has its specific load assigned to it.

Like I said, I decommissioned the Fullriver batteries because they have served me for many years. I wanted a longer runtime so I switched to Tall Tubular Batteries.

My panels are 1pcs of 560 watts generic solar panel and 2 Pcs of 180 watts Africell solar panels connected in 2S1P array configuration.

For charging, sometimes I get over 900 watts of energy from the panel at full sunlight. And over 60amps from the CC to these batteries.

I believe I have answered all the questions asked.

Thank you so much

futurenix:

No voltage at the terminals using multimeter.
CC does not see the battery
Inverter does not too.

Guess it's time to send it back. Their china technical office sent a message now saying a fuse must have broken inside and should be returned to the service center.

Thought I could rectify it without tempering the screws and save to and fro 40k for waybil and time.

What is your bulk and float charging voltage on ur charge controller
u used to av a sealed lead acid now u own a flooded battery.
I assumed u didn't change the charging profile.
U series 2 180w(say 36v 10a) then parallel them with 540w(41v 13a).
U will putting 36v 23a(828w max) through ur cables(6mm).
All these are assumed figure, I no africell don't perform up to the stated capacity.

Here is where u should suspect foul play.
Ur CC displaying 900w max is misleading I'll advise u get a DC meter to know the true figure
If ure using 6mm cable (assumed) n d length is above 10meters. U will experience voltage drop
u won't get up to that 36v
Check d body of ur battery if there is a c rating written on it.
Most lead acid are charged at 10-20% of their capacity.
D cable between ur CC n battery too should b 23mm since ure moving 60a into d dem.

Good thing you are calmer now..

First thing I want to point out is your PV configuration. So I assume you connected two 180w in series then this in parallel with a 560w panel. The difference in watts between the 560w and 360w panels is too much and the 360w ones will get damaged if your battery is full and no load to push power to.

About your battery,
1. Maybe the battery is an old stock and is already failing
2. Powmr old model controller, doesn't track battery voltage very well @12v configuration. Use a standalone voltmeters to confirm what voltage the battery actually gets to at absorb and float.

Another thing is tubular batteries need to be equalized once in a while, so maybe you can manually do that by charging to around 15v. You may need to check Google to know how to manually do it, or experienced people here can chime in. I don't have much experience with tubular batteries.
Cheers

why ain't ISPs (MTN, Airtel, etc) using Lithium batteries on their network masts Banks, etc, in their setUps ?

Wonderful.
You connected Solar Panels of different capacities. That's your first woe. I know some people advice you should EVEN though people wey get sense pass us says otherWise.

How often do you top-Up the battery electrolyte OR if you ever did at all ?

Are you sure the battery was original ? That brand is a known quality brand BUT that doesn't mean there ain't FAKEs.

see eh, without much idea what actually went wrong, something is clear - your solar panel is too small. Mixing solar panels of different wattage means the least becomes the overal wattage e.g 2pcs 300W and 6pcs 150Watts either series or parallel would bring the 300W solar panel down to level of the 150W panels.

Add to the fact you would be using the setUp for other things while it's struggling to recharge the batteries, then you would understand what went wrong.

Let's presume your charge controller is PWM or MPPT that doesn't know it's work, then you see you dug your grave yourself.

Now there are charge controllers that lies a lot. Dem plenty for market. Dem lie pass Federal Government hence reason it pays to have multi-Meter, and DC meter (though pricey) handy for when you have doubts.

Also, no one knows thickness of your cables, and distance from the solar panels to charge controller. e get reason PHCN / NEPA dey transmit light at Higher voltage than current.

we never wan reason say the solar panels sef fit get dey over rated gan sef. No need because we get enough reasons above already.

bassdow:

Most premium / quality batteries would service you up to 5-years and more.

but, you don't get such long life just like that. You need play your part as well.

You don't stress the batteries.
You don't run the batteries more than 20%. in fact the less, the better.
Those wey dey do things such as "3.5KVA with 24-volts 220AH battery" go hardly see up to 3-years complete.
You maintain the batteries, ensuring they're comfortable.

meanwhile, there's a known brand that's known to last 8+ years. It's name is Trojan. Problem be say, the price go discourage you. Even at exchange rate of ₦400 per Dollar.




but mind you, even the best premium battery, could go bad in less than 1-day if abused

Update Guys,

I have added the second 560 watts panel in series to the CC and removed the 180 watts Africell panels. So it's now 2pcs of 560amps half cut solar panels.

Please see my yield as at 10:35am.

I also attached an external battery meter (kindly ignore other readings on the screen). The battery meter and my voltmeter gives me 12.9 when Powmr CC shows 13.3

N/B my freezer is currently connected to the setup and running.

Trippledots:


You are maxing out the current capacity of that CC, at that rate the CC heats up and overheat protection will be activated and the CC will enter protection mode, stop charging for that while till the CC temp drops to around 45°C before it picks again. At the end of the day, you battery will end up not charging well.

You are better of switching to a 24v system or adding a cooling fan to help keep it cool.

Talking from experience.

I am currently planning to upgrade to a 48v system, so as to keep things running cooler and also extract more power from my PV and controller.

futurenix:
Pls anyone with info on where to get this fuse model? 150A

BlueStripper:



Thank you so much Sir. Since last week I made up my mind to upgrade to a 24v system.

If anyone has a 24v system for sale, 2.5 to 3.5kva, please let me know.

Insha Allah, I am buying a bigger lithium pack from Valto. Since I tasted Lithium, mind.

I don't know which devil pushed me to buy this Tubular Batteries. I regret it Walahi.

I beg, the inverter must have low power consumption. I don't want to add more troubles to my trouble.

Insha Allah, I am buying a bigger lithium pack from Valto. Since I tasted Lithium, I have had peace of mind.

What of Deka battery?
Ever heard of that brand ?

Good day bosses, please can someone help recommend a good Solar installation training institute in Abuja .


Thanks in advance
