Omotoda (better person), getting another cc no be biscuit for street oo. .

Boss, yes e nor easy coughing out another 91k but it's still better than wasting 2 420watts panel in his present set up.The 2 in parallel will contribute less than 20am in his set up while he has potential.of getting max 60 amps with a separate cc.His battery is 314ah so it can conveniently chest it

fuckboys:
please the charge controller went over 800w and then stops charging, what could be the issue. It's not throwing any codes

If you have reconnected the charge controller severally and same thing still happens,then it is most likely from your BMS.This is one of the advantages of smart bms to enable you see what is going on inside the pack.Try discharging the battery and let's see if it will wake up.Most likely one of the cells has gone above the over voltage cell protection value and BMS charge function is set to off.

I also think you are doing an overkill with your total PV input on the controller.

Get another controller and do 2s of the panels.

fuckboys:
why do suggest avoiding the inverter compressor?

Must new model LG and Samsung Fridge/Freezers come with inverter compressors.

My brother,personally I liike to keep things simple.Personal experience with inverter freezer don show me shege.I prefer the old,conventional manual compressor freezer type.After all the power consumption for me is okay .

mctfopt:
Go with Scanfrost. I have a non inverter 250L Scanfrost freezer that draws a maximum of 160w. Freezer keeps everything frozen all day long after running for 8 hours daily (8am to 4pm)

I agree. I use this too and its awesome. Avoid the inverter compressor though

Intellab:
How do I confirm this is 314ah lifepo4? These are batteries from Valto.

Did you you tamper with the BMS settings?Call Valto,he will send the correct settings to you.

Its not a big issue

Hello, @bolded; who?

@Mrreed

Dam5reey1:
Haisic Batteries does not look like Grade B. Though I didn't get full pictures more like Gotion, Hithium, Grade Cells 280AH complete..

The Real Grade B will be revealed soon

We carry chair, siddon dey wait!

Mrreed:
You say?

Technically I don't consider this 800k a really good deal because someone here builds same 24v 280ah with Grade A cells and smart BMS for #840k.So why pay 800k for Grade B cells ,with no smart BMS?

Dam5reey1:
That's a Plus, the Cells was well packed, protected and padded, which prevents it from issues, that may arrive from Terminal connections.

I am talking from a perspective of Experience, from resolving issues from clients, Laser welding best, Rubber on each cell, also casing serves as compression..

It's not smart BMS.. but Has Bluetooth for Serial Number Identification.

What does this mean please?

fuckboys:
The eagle has landed thanks to dare for showing us good deals

Does this Haisic have a smart bms? Can you monitor cell performance via app?

fuckboys:
omo you go need like 6kva of solar power to power this setup

You can say that again. to ensure optimal charging of the battery.That's a massive battery bank.

For the tubular lovers,see your 'fraudulent'calculations

Ahyjo:
Good morning. Please in a system with 6 x 225W and a PWM CC, what’s the best setup to harness the best out of these panels either in 24V or 12V as both setups are possible due to the availability of inverters in both voltages?

Get MPPT and use the 24v inverter

numericalguy:
The inverter is a Luminous 24v/1.5KVA and does not have editable settings

Though I have solar panels and an MPPT charge controller

Guy,go ahead .Nothing do you!I use my Luminous Zelios with my LFP,no issues

abuzz33:
Not correct. A quality tubular battery will give you 1500 cycles at 80% discharge. That's why it's called deep cycle. At 80% discharge a 220ah 24v will give you 4,224w.

Luminous has great batteries. I ran their inverlast batteries for 4 years straight from 6pm -7am and they still held up to 80% capacity.

Oya guy,go and buy tubular and enjoy!!

Alueheal:
budget 540k

Talk to Dam5reey.He posted a Joykoo 2.5kw for 540k or so.You can also talk to Mrreed,he can build 2.5,kw for you for less but with HDF casing.You have a solution already

numericalguy:
It has a switch with two positions namely:-
1) Regulated UPS
2) Unregulated UPS

This is not for charging. This switch is for either inverter mode or ups mode,what some label as wide or narrow use.

If you don't gave option for battery selection, you can try it but be sure your LFP has a monitoring app.You won't have issues with the charging current.Indian inverters of that capacity hardly exceed 20amp charging current..Its the charging voltage that we are concerned about.I believe you should be fine .Like Dam5reey will say,you can do it for science

abuzz33:
2 tubular batteries will give you 4kwh. A lifepo4 battery of that size will cost you 900k. That's affordability factor.

If Nigeria produced batteries like India a 200ah 12v tubular battery would cost less then 250k. Meaning that 2 would cost 500k.

Two tubular of 220ah * 24v will give you 5280 watts but the caveat is you are only safe discharging 50% which is just 2.5kw same as LFP which can be discharged to zero, has higher charge acceptance,less bulky and greater number of cycles.Let's not go back
please. We have been through this calculations/ analysis before.The best you can get from a well maintained tubular us 1500 cycles and that's provided you do about 50% DOD.How about the mess they create? Let's move on to Canaan. We left Egypt a long time ago

numericalguy:
For someone like me with an existing system and my gel batries are no longer serving.
Will I need to change my inverter as i once heard that Lithium batteries cannot work with regular inverters that are commonly used to charge lead-acid batteries.

Does your inverter have adjustable setting at the back for SMF,Tubular or flat plate batteries?.If it does use SMF,if not it will have either HC ( High Charging) or Normal Charging ( NC).I use Luminous Zelios 1.5kva for LFP and no issues. Its charging current is about 18amps and with SMF setting the max charging voltage is 28.8v which is still fine.I have solar set up with it though but the one in my Madam office has no solar and it works fine as well.

abuzz33:
Tubular batteries are affordable which us the no 1 reason. The premium batteries like luminous provide at least 4 years of deep discharge at 80% and over 7 years at 50% discharge. I have experienced it. For small setups lead acid is good enough.

How are they affordable? GSR 240ah is 290k,Luminous is around 300-320k?

What is the price of Lithium? I am beginning to believe some people just drop comments to set us back.If you can afford 2 tubular batteries ,then you can afford Lithium! Period!!!

Alueheal:
300k each tubular battery

Guy with 600k you will get llitjium.battery 25.6v 100 ah.Cworth is 555k,Valto should be within the 600k range, @Mrreed Lifepo4 of same capacity is #420k. and if you can wait,Deriy battery is about 385k.So you see you have more than enough options for LFP that will give you same capacity as 2 tubular batteries and last linger,charges faster

Please delete the thought of tubular from your subconscious mind .The enemy wants to have you but we will pray for you

Please leave tubular forever.

Alueheal:
Please who can recommend a good 2.5 KVA Inverter 24v and a good tubular battery brand..
I don't have money for lithium battery please take note. Thanks

2.5kvs inverter - Luminous/ Genus/ Euronet

Tubular batteries - GSR ,Haustrom,Luminous

Please note that presently good quality tubular batteries are more expensive than Lithium.So state your budget for the batteries and I am sure you will get something worth your money in the Lithium space.

bassdow:
All brands have such.
Just so we are clear, what i meant is, there are inVerters that supports multiple voltages e.g 12-volts / 24-volts / 48-volts.
So it's often better you go with one that supports more than 1 voltage e.g 12-volt / 24-volts OR 24-volt / 48-volt OR 12-volts / 24-volts / 48-volts.

That way, your major (or only) reason for upgrading your INVERTER wouldn't be because it does not support your battery configuration.

Same applies to Charge Controllers

I am just knowing this too. Perhaps not in Nigeria

HeavenlyBang:
Spot on. I don't really understand some of the agenda here.

One say na just 200k difference. How much is minimum wage?

Then all the talk about Hithium and Eve and whatnot. Lmao, even Cworth's obvious Grade B batteries are an excellent deal for plenty of people. 180k for Cworth Grade B vs 300k for Powmr Grade A is a very easy choice for most people.

My brother don't mind our people.Like @ dollarnaira will say,solar journey na individual journey. Budget based on your requirements and pocket.

HeavenlyBang:
Instead of doing "you can", how about you actually say how it can be done.

Na person carry the Deriy batteries come here, since then e just be like say e dey vex some people.

If you have an update on how to make solar cheaper for people, then share and quit meaningless tirades. I no dey understand this thread sometimes.

Bros ,as in you get it shey! We are after cheaper solar alternatives.Shikena!.People are just something else.Someone gave us cheaper and quality alternatives people are exhibiting hate up and down.Who here will sell 25.6v 2.5kw for #384k? Yet that's Deriy's price. In fact I got mine for #358,500 before the dollar rate moved and they had to do price adjustment. And its doing great.J also have Valto's 2.5kw ,doing great also.The aim is let's get cheaper alternatives and everyone can make their choice.

HeavenlyBang:
Which is weird because surely we want higher voltage than current. I think Jinko's setup is best. 550w = 41 X 13a or so.

Abi? I thought so too

fuckboys:
but this is a Cworth 420w panel

Maybe there is nothing to bother about then but I know my Felicity 260 w panels of close to 4 years have about 36.. something volt as VOC so I was only wondering why higher warrage will have same VOC .Perhaps the experts can shed light on this

Bruteality1:
Is this solar panel compatible for a 48v inverter?

Yes it is compatible for any inverter.However,I will be bothered why a 550w panel will have just 36v as VOC.My 260 watts Felicity panel has 36v VOC so something isn't right about that panel.

bkuranga:
Can you please recommend a different controller that can accommodate the 3 panels and maybe also give room for future upgrade?

Such controllers wont come cheap; you will be looking at 100amp to 120amp. Best thing is to buy a single unit of panel more and do your connection as 2s2p

Guys, are cworth inverters low frequency inverters? If not what other brands of inverters are low frequency ?

Any side effect in combining different lifepo4 battery of same voltage in parallel. Say combining Cworth 25.6v100ah in parallel with say SMS 25.6v 100ah?

BigDickProblems:
Just a quick question Guys.

Please is it recommended to set your charging voltage at around 17V to 18V for a 12.8V battery?

If no, what are the repercussions. Thanks.

The question is why would you want to do that on your LFP. In fact your BMS would not even allow it to get to those voltage range before shutting down due to OVER voltage protection .Max charge voltage for LFP is 3.65v per cell which is why most 12v LFP chargers are rated 14.6v, even though it is not recommended to charge up to the max voltage allowable.

Mrreed:
If you can afford to spend the total here, here is a better option
There is a brand "Haisic" that sells
25.6v 8kwh for 800k (as contained in their spec sheet, it's a Grade B battery)
24v 4kva transformerless inverter 340-350k
590w Jinko panel x4 is better
6mm cable, breakers, SPD and the box will cost you less than 160k if you are staying in a bungalow and will be installing the system close to your DB

Is he not better with your own 25.6v 7kw Grade A cell for 840k if he doesn't mind wooden box?Abi has your price change ni?
