Good morning all, I'm experiencing an issue with my Welion inverter. It had a short circuit this morning, causing both input and output currents to shut down. Currently, I'm getting an error code 08. How can I sort it out?

Bus voltage too high?

I don't think there's anything you can do to it.

Try to reset the inverter

Good morning all. I am back again. I have two Mercury tubular batteries which I installed around March last year. They are serving me very well and I have not experienced any day of darkness since I installed them, either morning or night, even during days of rainfall. My inverter is a 24v Mercury inverter.

However, with all the information I have been reading here, I am planning on switching to a Lithium battery. I don't want to spend up to a million naira on the battery upgrade because my load demand is not much but I also want to be future-proof with whatever I buy. I generally consume at most 300w continuously, which is my fridge, TV, fans, and bulbs.

I am thinking of buying a 3.6kwh lithium battery but my brother is advising that I go for a 5kwh battery which will be above a million naira.

My first question is: will the number of hours the 3.6kwh lithium battery last be much different from the current tubular batteries I have? How many hours am I likely to get from the 3.6kwh battery with a load of 300w? Is the upgrade from two tubular batteries to a 3.6kwh battery worth it?

Secondly, what will be your advice regarding the best brand to buy? From what I have seen, the options are buying from Mr Valto, or buying Cworth batteries or Haisic batteries. Which will be the most cost-effective and reliable option? Yes, I want a cheaper option but also an option that won't make me regret a few years later due to the performance of the battery

Sorry for the long message

If it serves you, use it then upgrade after they have served their useful life.


Unless you have another location to use the tubular battery, I see no reason you should be upgrading it

Machiny:
let's say one has 4000w panel and load of 600w.

Would run the load well

HeavenlyBang:
Using an inverter without a battery of any sort is impractical in Nigeria.

What happens when sun suddenly goes down or there's cloud cover and your panels can't supply the needed power instantaneously?

Inverters marketed as being usable without batteries are only valid in countries where grid supply is constant. So when any of the above happens, the inverter draws power from grid to fill up the gap.

This is not totally true.

If your pv is sufficient to run your load, it works as per design.

Nigerian electrician hates to ground a house.

It's appealing the level of no protection they put up while wiring the house.

87% of Nigerian electrician needs to go back to tech school for a one month intensive course on electrical protection.

Nothing makes me sad to see multiple houses without basic electrical earth and lightning protection.

Is not as if they don't know, is just that they will still do something shabby and call it protection, so they end up pocketing the money....

This is how they complete the workmanship >: .

Don't ask me how I know

officialfestus:
7s 2.4kw in progress.

Please what's update on this, how can I reach out?

I will like to find out cost of this assembly and other technical details

aaforke:
My people.
What is the best recommendation for a 1.5kva set up
?.
My 1kva luminous just developed fault, I have a decent tubular battery.
I just got 2 africell 330 watts panel. I am just confused as to which inverter I should go for. Ideally I want to be on the tubular for now then replace much later with a lithium battery.

Please Inverter recommendations Biko.

Bless

Buy satchet inverter, I don't know if you have external chargers.

mctfopt:
Crossed an installation yesterday. More than 30 solar panels mounted directly to the roof. No roof mounting kit, cables running bare on the roof.


Often a product of "I can do it cheaper" group of companies.

Well, it works. Until it doesn't.

Funniest thing about this is doing maintenance on it will be very tedious.

But till then

bassdow:
quite agree with you BUT paying millions to an installer, doesn't automatically make an Installer good enough. Na your work to employ services of a good installer, then negotiate with them. Sometimes, na even the Cheap one that might end up serving you more.

Exactly.
Check it cost of materials 5m
Workmanship 200k
The roof very high.


Solar installation is following the electrical wiring trend .

Na who dey sell market they gat am clear

FEGEITOK:
SRNE and Schneider.

Rest of the house, the amplifier and the fan are on the SRNE.

Smart TV is on the Schneider

Hybrid or TF based?

Try and switch/set the inverter to ups.

It ought to solve that problem

FEGEITOK:
What is the phenomenon called in which if you turn off a fan or an amplifier the smart TV blinks for a millisecond?

What is the reason why that happens when my inverter is powering the smart TV and the fan or the smart TV and the amplifier?

What type of inverter?

HeavenlyBang:
Terrible quote.

For one, we do not recommend tubular batteries on this thread anymore.

- Switch that inverter to a 5KW 48v one. Buy from Growatt or SRNE or Felicity. Same price.

- Buy a 5kwh 48v Lithium battery. You can buy from Valto here, or Deriy, or talk to Dam5reey1. Same price or even cheaper than what you've been quoted.

- Buy six 620w Jinko panels from Fouani. 830k.

Solar cable you need is 6mm and they don't cost more than 4k per yard. That's 80k. Also no need for a battery rack with a lithium battery.

Buy all of these yourself. Let the installer buy the other accessories and you pay for installation. You should save yourself about 150k doing this and you'd have a significantly better setup.

After he buy everything he go come dey proce installer 100k .

Nobody talks about this stuff on this thread.

If you are going to spend on what has been recommended (the recommendation is Valery valid) be will to spend well on a good installer.

Is funny a lot of people will spend good money on equipment the spoil it with cheap installation....

Inverter will damage then you will hear this product is not good

Good morning house,
Please refer me to where I can buy fuse/fuse holder for solar panels in arena or anywhere within Lagos State.

Thank you 🙏🏾

obinna37:
I thought it's better to use 12v solar panel on 12v system if you're using pwm charge controller,pls correct me if I'm wrong

You are correct.

obinna37:
what of if the 250w solar panels are 24v,will it work well with pwm charge controller

Yes.

Elizkid:
Thanks so much

Since I’ll be using a sachet inverter and a pwm, will it be enough to charge the 100ah Lifepo4 with 200w load simultaneously?

Also forgive my dumb question, why do people buy tubular batteries when the lifepo4 equivalent is only slightly higher in price? Is there a disadvantage to using lifepo4? I’m asking cause I’ve only used Tubular and Lead since 2020. I don’t know much about these things.


Lastly, which is better? Four 250w Canadian-used poly panels? Or one 650w Jinko mono panel?

Again, forgive my dumb questions please.

If you Will be using a pwm cc, the 250w is okay just make sure the cc is the type that's compatible for lithium battery.

Buying a mppt for 12v Wil limit you to just 800w of PV.

Will the 4 unit of 250w run the 200w load and charge yes.

So it's your decision

Uyinosa:
1. What is the budget for a household that has Big fan (1), medium fan(2), Bulbs (6), Laptop (2), TV( 55 (inches). Note that all the bulbs will not be switch on at night.

2. Another option - Same above, + one fridge

Choice: Solar
High quality is my priority. I reside in lagos

Add wattage to the load it will help you easily get guidelines

fuckboys:
i confirmed today chief, was already blazing 80w at 35v of total panel voltage earlier this morning.

👍🏾

fuckboys:
sms is 80a 400v max pv input. Also has a nominal voltage of 250v.

This has a more broad pv input voltage, from 30-500.

First confirm if it will charge at 30v.

fuckboys:
i ordered this from jumia, is it the original?

This Na change over oh

fuckboys:
there is an output on the battery, no thats not the inverter I'm using, it's sukam falcon plus 1.5kva

Inverter get problem 💯

fuckboys:
morning chief, please I have custom built lfp battery with the upper bigger terminals as the inverter or discharge ports, and the small bottom terminals as the charging ports like solar and chargers.

It's a 105ah battery capacity, can i add a cworth 100ah lfp battery to it in parallel to increase my capacity? Can they be compatible?

If yes, which of the terminals do I run the parallel connection from?

If this is the inverter you are using, there's is a likely hood that the Inverter has developed fault.

The "main trip" notification is probably when the inverter cannot sense input from utility.


For your battery, confirm there's output on the battery terminal.

If there's is output, try to discharge it and charge it again.

Oshomo12:
I sent them an email already, like two days ago, but no reply yet.

Okay. Can you drop the address?

Oshomo12:
Good morning all, I have one 2kva 12V Sako inverter that drops charging to as low as 2A or should I say, the charging current starts dropping immediately it starts charging, no matter the level of the battery discharge (LiFePo4). Even though the charging current is set to 50A, PHCN charging for now, no solar panels added yet. The inverter will need to be restarted like 2 to 3 times before it starts ramping up the charging to 47A. Any fix or settings to correct this issue?

Send to service centre that's the only solution

icjunior:
Please who uses smarten inverter here,mine just started tripping off with this message "Short circuit,please check wiring" The batteries are fine.


I don't know what that means,but I noticed recently that my appliances would sometimes shock me,off and on happening.

Disconnect your load and restart the inverter.

If it works fine, it's your load.

If it doesn't, it's a problem on the board

Currently this page is on 2016.

Can we push it to the present time 2025

officialfestus:
50p 3s in progress.

Boss how do you calculate the gauge/size of your battery strips?

dollarnaira:
Final result:
68.4ah
759.24wh

How much did you buy the meter you used for the test .

I will like to get one

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

It's not for the charging.

I think this is for the input from mains.

It's good someone has actually experimented the lithium battery with Indian inverters.

@brightk

Ahyjo:
please I need a reliable plug here to get these and a good dc cable from.

@linnov8

numericalguy:
Good morning gurus in the house,

My Gel type of batteries are no longer serving me and I searched for their replacement with no succes.

My Issues are as follows.

1) How do I get good gel type of 12v/200ah batteries
2) In the event that I am unable to get the gel type batteries. How do I identify good and genuine tubular batteries (12v/200ah) as there seems to be so much fake and substandard batteries in the market these days.

Gel batteries are expensive.
However you can go with quanta, it's agm (I think this is the most expensive presently around 400k)
