This Sonoff is just rubbish, mine stopped working it just 1year of use.

Anybody telling you to use lead acid in this time and age, is an e..........

Running a very old thermocool fridge since 5am till 8:05 am before leaving the house.

@Mavor, the truth is, 1.5m can't get you your stop guard. That gaming console alone, the power consumption is worth two of my 219L deep freezer!
You will need to remove that first.

Good morning all, let me shake the table small, kindly watch and give your thought

Please is the icell stand alone?

Yes, Icell-power 2.5kva, transformer based, fangpusung mppt controller etc

dollarnaira:
Have you confirmed this?

Yes, I have. It happened to Icell-power inverter. I installed it and did earthing, only for the client to call an electrician who worked on the system after 4years, since I couldn't get to him in about a week. He bypass the earthing I did, the first rain of that year knocked the inverter out. This was an installation of 4 years old.

Mavor:
Please for budgetary reasons, I am thinking of getting a 5KW SRNE inverter with 5.12kWh Lithium Phosphate Iron battery and 5.5kWp Solar panels (10 panels x 550w). My home load is a 2HP LG Dual Inverter AC, One 55 inch LG flatscreen, 2 laptops, 1 video game console, 2 standing fans, one fridge, one water dispenser and 12 energy bulbs. Please how can I efficiently manage the load application on the inverter system to prolong its lifespan and when during a 24 hour period can I switch on the AC, what appliances do I need to switch off when using the AC and how many hours in a day can I use the AC? Kindly advise please. Thank you.

Your load is too much for your battery, the minimum is 10kwh. Na you won use AC 24hrs. Pañels size is ok for a 10kwh battery.

Edited:
I read it wrong, use it during the afternoon, from 12noon to 6pm. This depends on how low you depleted your battery over night.

Good day house. Anyone that is willing should give a helping hand.
I bought products of solar system from one DE BLESSED SOLOMON GLOBAL SOLAR ENERGY from Alaba. Instead of brand new panels, he sent used but that's not my anger. My anger is he sent a nonworking mppt charge controller which I returned with him promising to replace it together with 2 extra panels he did not send that I ordered when the former once where on the way. He was giving me fake reasons since early February till now he is no more taking my calls or answering my WhatsApp messages. His name is SOLOMON CHIBUIKE OGBODO. If any one he has done such a thing to or knows how to get to him should please contact me. I have his phone and account numbers.

Sorry, I will be very rude here. This is none of our business, please!! Is he a member of this forum? When you won do business with him, did you involve us? We have people selling those things here, you choose to go your own way. Now things have gone south, Alaba is very big, I will advice you take it up with their Union. Good luck.

This issue of lightning frying Inverters, is this limited to only All in one inverters or can this happen to stand alone inverters too

It happens to them all!!

mctfopt:
That's another thing. A friend, an installer gave someone a quote for ₦2.5m for some solar solutions, the client laughed at him and said if he has ₦2.5m that he would be out of the country where there is 24/7 power.

Crooked installers get the job most of the time as compromising on quality means nothing to them. Eg using a 40A PWM to run a 5kwh PV set up. Lol

Lol, I remember when I gave a quote for an installation(ICT section) in a university, the VC and co told me it was expensive that I should reduce it. I told them no, that was the last time I heard from them. Only for them to call a big installer who did it 200k cheaper!

The 200k difference was for earthing the building and equipment.

Well, the transient current from the inverter damaged equipment worth over a million(this was when dollar cheap o, around ₦400/$).

dollarnaira:
Feel it with your hands for a description.
Rectangular or cylindrical?
Partia or longl continuity.

The cells are Poche cells, I strongly believe they are Li-ion/polymer not lifepo4. Some of the cells are probably bad.

RickyM:
After my inverter got fried, I noticed two days later that the battery started blinking red even though I’m still on four bar which isn’t right and I called to inform him and then that same night the battery tripped off so I took it to his office at Eleyele from Ekiti and he texted me days later that he’s done with it only to get it back and test it with the pure sine wave inverter I got from Valto and realize that it’s still doing the same thing and from full four bar, it will trip off and also after while trying to recharge it back up it will charge from one bar and then straight to four bar instead of charging one bar and then second bar and then the third before the fourth which is the last bar.
I called him last night immediately to inform him that the battery is still doing the same thing and he was claiming it was because it had been left idle for a while which is nothing but a lie I believe.
I’ve been calling him today since morning and he won’t pick up my phone please help me with police plugggggg

I don't know if you will be able to know the kind of cells he used, is it lifepo4 or liion(18650 cells), the type in laptop battery.

tivta:
Wetin valto do?

Valto didn't do anything ooo. The guy was afraid initially to deal with valto, due to his past experience with one mumu in Ibadan.

amicdan:
Ok Boss, it’s not parallel ? So I need to correct it to parallel right? Thanks boss.

Yes you need to do that. Negative wires together at one end, and positive wires together at the other end (that's parallel).

amicdan:
Hi everyone,

I have 2 335 watt panels with :
1. Maximum power voltage ( 37.6 V ).
2. Maximum power current ( 8.91 A ).

* If the 2 panels are connected in series,
Output = 8.91 A and 75.2 Volts

* If the 2 panels are connected in parallel,
Output = 17.82 A and 37.6 Volts

Just to confirm if the above calculation is correct?

My 60 amps PWM is delivering a maximum of 8.7 A at peak and voltage as high as 65 volts during float with the panels in parallel connection.

This is a 12V setup ( 220 amps tubular battery and battery hardly gets full in a day without usage during the day.

Just to confirm if my connection was done right.

Your connection was done wrong, those panels are connected in series and not in parallel.

The correct one is your second option
17.8A and 37.6V

Hello everyone,

I had an installer complete a 2.5KVA solar at my home. However, a piece of the battery cap broke and has been crusting leading to at least 1 episode of power outage. I fear that this would recur and of course, the installer is MIA, lots of excuses and stories. I am trying to fix this and a picture is attached, kindly advise.

Where can I buy the cap and is it a DIY replacement or do I have a bigger challenge?

Installation is less than 6 months old by the way. That's one heck of an installer for you.

I can't remember, I think someone here did something like this years back on this forum.

RickyM:
Good morning and happy Sunday to y’all great people out here🫡🫡🫡
I want to narrate my horrible experience with a guy known as BlueCross in Eleyele Ibadan right opposite Anwar’u Islam Grammar School, it will be a quite long story but I will make it short as much as I can.
Met him around June 2023 on jiji and we talked about doing a solar solution that is capable of charging my gadgets only, although the post of his I saw on jiji states that the solution can run a TV for 5hrs and it’s the same solution I requested for. His guy came around and installed it but then with just my 33W charger, the solution will trip off after 2hrs of charging when the sun already went down of which I contact him and made him realize this isn’t what we agreed on but I let it slide.
In October, I saw his whatsapp status one day with 10kwh battery just built by him so I said I would love half the capacity of that which is 5kwh I believe as I want to make use of it to run freezer for ice block business.
He gave me quote and I said he should take the one I had before and then I’ll add funds to it which we both agreed.
He said he will deliver within two weeks max and I paid him but more than 2months after before he came to do the installation giving me excuses of not being able to get his hands on the inverter he wanted to use for me.
Eventually he came and do the installation and after charging the battery full then I plug in my 110W freezer alone from exactly 4:30pm to run the test and behold the battery trip off at exactly 11:46pm in the same night which means it only lasted 7hrs 16minutes.
I contacted him and made him realize this can never be a 5kwh battery as there is no way it will only lasted for 7hrs as I expect nothing less than 30hrs at least from it.
Does anyone here has a police connect in that area or close by?
I do not mind spending my last kobo to make this guy realize the fraud that he is because I am frustrated by all of his doings.

Now I understand your apprehension with valto!!

mctfopt:
You still do, but risk of damage is now significantly reduced.

THANK YOU SIR.

You just summarised all my story!!

Decentlyproud:
Does it mean those that are off grid should have no worry about thunderstorm and rain??

Take it slow, Nobody is completely free. If you are doing solar, safety first, good earthing is not negotiable. If you stay in an area that does not experience direct hit by lightning aka Thor, most of the power surges come from the grid lines. So, eliminate that first and do propare earthing system for all your installation. Our grid is the number one weak link in the system.

RickyM:
Got the battery pack delivered today…Haven’t tested, my inverter got fried by lightning and it’s been at Felicity company since Tuesday.

Sorry to hear about the inverter. Was it connected to the grid? I keep saying this, and will say it again: if you don't have resources to install/correct the earthing system in our house, please don't charge/connect your inverter via grid. If you must charge via grid, you MUST be there to monitor it. Once you sense rain or a storm coming, DISCONNECT YOUR SYSTEM COMPLETELY FROM THE GRID.

obinna37:
Pls house, some one want to buy 420w solar panel,he is considering between bifacial and monofacial which is better,I have tested the two, bifacial is reading high in voltage and current

Bifacial is not for us here.

Good afternoon my people, is there a sub-pump machine with a soft start?

babaegun:
My dashboard today...

Solar is sweet..

All thanks to Oga Dapsyra (Senior Mentor), Bigbrovar (Senior Mentor), Ojesky (Senior Mentor, node-red master), isangjohnson (assisted me in getting a good price with my Eve batteries.) & zeestone99 (soft spoken, gentle and very reliable shipping Master. He got my Eve batteries to Abuja seamlessly ).

AC 24/7. Life is good.

You are welcome back!


sincerely, I hate those flames solar panels, they degrade fast with time.

RickyM:
Actually he said the BMS he wanted to use was misbehaving so he ordered another one that will be delivered on Monday.

Oh, that's ok. He will definitely deliver.

RickyM:
Delivery date shifted by 24hrs he said.

It depends on your location, from my side, the driver couldn't move on time due to the traffic coming down.

Relax your mind, you will enjoy it.

oloet:
Baba let me use this analogy....
Why person go dey compare windows laptop battery to a MacBook Pro battery 🤭

You are not very nice!!

RickyM:
That sounds pretty impressive I must say.
An update‼️‼️
We agreed on 7.1kwh battery pack and 60% of the agreed price is paid, he promised that I’d get it by Monday…I’m looking forward to that now.

That's nice, I paid him full and never bothered to call him. He was just disturbing me with messages nii

When lifepo4 started here on this forum, I spoke for it but when I needed to replace my bank then, funds was not available, so I thought and wished. I went for lead acid, quanta (I can never use any brand of flooded, be it Trojan or so). I used my quanta well, I have a meter to check my ah in and out. I hardly go below 65%[I use around 30-35% of the capacity). 4 years is almost here of using it, the capacity has dropped to 30%.

If you must use lead acid, go the route of 2v.

Morning if you read this thread from the beginning, you will notice the change in battery technology in Nigeria.

About 10 to 12 years ago , generally Nigerians were using gel maintenance free batteries, while those that have money used agm batteries.

I was stuck with gel batteries. Agm
Of course was better but cost more.

All of a sudden flooded batteries became the new baby ( trojan and one American battery ).
Of course new battery tech will initially cost someone a kidney to get.

But a few of us on this forum were on this new battery (flooded batteries) , and we all dreamed to acquire these batteries.

All of a sudden tubular batteries walks in with a cheaper version of flooded batteries. I was on my last lap of my maintenance free batteries.

It was far cheaper than the original flooded, but same tech. I joined tubular immediately and so did most nigerians leaving behind gel batteries , agm and even original flooded batteries.

Then the new battery tech in Nigeria, lithium far better than original flooded, agm and tubular batteries. But like i mentioned earlier new tech wil cost an arm , a leg with even kidney this time. I am very confident a cheaper version of lithium will come along soon. And nigerians will do the needful and migrate. Till then we go manage our tubular batteries. My respect goes to those already on lithium it is not an easy fit to achieve.. someone has to break in new technology.

The point is, to get me wrong, flooded lead acid batteries should NEVER come to the picture in the first instance!! Cos , it a bettery chemistry been faced out. No body on other side of this world still use flooded batteries. Its was an aberration to start using it here as a new born tech. Immediately they stopped using it out there, they started dumping it here. Flooded batteries were installed out side the living environment of any animal, not to talk of human being!!

Our people started installing it in a human being living rooms! What does that make us?

Uniquewise:
Really?

Solar panels are 300w * 8

Kindly Google search the symbol for AC and DC, compare it the the symbol after your 400v ~ written on that breaker.

RickyM:
I am trying to believe so…I am in talk with him for 24v 280Ah

He dares not f....k. up!!
The cells I got from him are well balanced too, no funny behaviour so far! The people I got it for used it to 2% at a time, but charged it up to 100% with 0.002 deviation at the end.

RickyM:
Since there is no way to really figure out the true Ampere of a battery then it’s hard to even trust DYI as I paid a guy to make 24v 5kwh battery for me and it won’t even run my 110w freezer more than 7hrs which is just outright scam to me and that’s why I am looking to buy a ready made to add to this in parallel since I just got this last month.
Trusting DYI has became an issue for me but yet still I believe there are true people out there.
Do you care to help with Valto number?

Valto's cells capacity checks out. I have bought and tested his cells to full capacity.
