We assisted an Installer this 8kw, 30kwh storage and 7kw peak panel to add some magic touches

Communication with battery and inverter done.
Inverter has Wifi for monitoring..

Can you do a remote shut down of the Felicity inverter via the WiFi monitoring app? If no, what features does it have?

What could be responsible for this burn and cracks?
This is a 6yr panel but two of my panels suddenly one after the other developed this syndrome.

Is this panel by chance still functional?

Low quality, often cheaper than premium PVs, are prone to failure after some years of service. This failure is attributed to low quality part used to make the solar panels which makes them cheaper than the premium brand. Most that I know of fails after 3 years. This one even tried to get to 6 years.

I wouldn't use the solar panels if I'm you. Best to discard it to replace it.

On the other hand you can always check to see if the solar panels are correctly installed. Check out a good case of bad connection that may lead to catastrophic failure here:

Welcome to the Alpha ESS

My man it looks like it's strictly sales you are into. After sales service is not in any way part of the job description right?

I wish people who build houses could give provision to having the house powered by renewable energy and thus make provision for some of these things like output DBs, input source and PV conduit point. Your people had to go through hell to provide this. Good job especially on the wall cracking which was just enough as was needed.

Budget Back up...
Inverter 2kva 1.6Kw
Battery 3.7KWH.. capacity test results 3.84kwh...
Video coming soon..

This Sako is 12v? Nice

Haykay2001:
Hv u or anyone here used Kartel panels before? Does it come close to jinko and co?

Nah, wouldn't even try to use it for any serious ptoject

ManAdii:
Wow, great update.

What's your review about these cworth panels?.
I wanted to get one but was skeptical since they're relatively new in the market.

Get Jinko or Longi or original Canadian solar

kristien4:
Please @all, i have a little problem with my battery. They are 2 pieces of 10kwh lifepo4 connected in parallel, when being used, they dont drain uniformly, one battery could be at 87% the other at 95% . Is this normal?

Increase the size of the parallel cable or use a busbar to do the parallel.

if u want to discredit someone,please do it in a way no one suspects u of been envious.......

Please can we allow people share their experience on this platform without attacking the messenger? Some may have things to share, which they may be reluctant to share, if they see attacks on people who share their experience.

OgogoroFreak:
Which of these inverters should I go for and why?

Growatt any day.

ANTIFA:
I don't even understand, at first they said Lagos air, now they said they came but I wasn't around... No call no nothing but it has updated.

Go to the NIPOST office nearest to you and pick your package. NIPOST don't do home delivery on AliExpress packages. When you see "unsuccessful delivery" it means your package is in their post office, it doesn't literally mean they tried to deliver and you weren't home

BigDickProblems:
Can you share the temperature of your room via your phone app. That can actually give a clue as to such a high temperature.
Bro in 35 degree celcius, you’ll sweat in a not-well ventilated room not to talk of 49 degree. Battery health is paramount.

The temperature is not the room temperature. It's the temperature of the component inside the inverter (MosFETs).

Simple preventive maintenance does wonders to longevity of equipment

HeavenlyBang:
Laying your panels flat on a roof is an easy lifehack until they start hitting 80°C.

How is the controller still working

ManAdii:
These Sako issues I have read here was why I was hell bent on buying a TBB inverter again I wanted to upgrade my inverter to 3kw.

Even though I saw cheaper options which was half the price of the one I finally got.

I used their 1.2kva for 2 years without any problems. I resold it and the buyer is still using it until now.

I used the 1.2kva to power my home appliances including my refrigerator.

Any product that can give 5 years of warranty is no joke.

The cworth battery I got I just hope it won't disappoint since it's still a relatively new brand in the market.

Care to share the cost of these TBB inverters?

fashrola:
This product link will take you to their store

https://a.aliexpress.com/_mrVUHob

Lol. The price gave it away. Unless it's a toy shaped like this. This power station is sold from $770 in Alibaba

dollarnaira:
Baba do low budget stand alones.
PowMr 100k
100ah 240k
Satchet inverter 3kva 100k
Active Balancer 10k
400w × 2 = 220k
Cable

But most guys want beautiful boxes.
The above is a mini killer, ugly but working.

Hi, is the PowMr 100ah now 240k?

Haykay2001:
Hv been asking them for their service center address in lag, no single reply.. Just so sad..

@sakopower help here

fashrola:
In all you do ensure you stay away from this shop

they are scammers (Pix attached)

Please drop the shop link.

Though the only thing a shop in AliExpress can do is waste my time, they can't really scam me.

Haykay2001:
Not just those 2 model at all.. Will advice ppl to stay away from sako for now.. I have been having issues with their inverter and battery.. . One of the cell in their battery is very low.. Been asking for solution how to balance it but nothing is forth coming.. The inverter itself have been giving issues since the day of Instllation.. That was early Nov 2024 less than 3 mths ago.. Now battery is no longer balance. I was told i need a load to lower the high voltage, which i know nothing abt.. I dont build battery. For the last 3days now they stopped responding to messages.
I asked for their service center in Lagos so that i can send it for repair still no reply at all.. Items of less than 3mths and the customer is messaging me every single day.. Always on my neck.. 6.2kva paired with 10kwh battery.
Anyone with solution should kindly help me out abeg.. 🙏 🙏 🙏

What is V1 to V4 readings? Batteries are out of balance. I wish their BMS has an active balance function. Also most of these batteries are welded, not bolted or screwed on, so servicing them is super hard without special tools.

Best bet is to return it to them.

Let them handle it. It's still under warranty.

Hello house 👋🏾

I have a problem with my 8kva felicity inverter and my installer isn’t even coming to check it.

It trips off load all the time. I bought 8 unit of 600W panels, only 7 was connected, 1 was broken. At 100% capacity, it supposed to give me 4.2kW but I know that it’s not possible. I’d be receiving 3.5 - 4kW but I don’t get up to 500W total wattage from it. The 4 wet batteries are starplus products.

Now it doesn’t work effectively except I connect it to NEPA, but I should not be on NEPA because I’m not paying for it. I was even disconnected from NEPA which is very much ok, my solar energy system is supposed to be sufficient for me without NEPA.

The installer has refused to show up. What do you advise?

I’m in Lagos, in case you suggest another experienced installer and you can share their contact with me.

StarPlus is a low-quality tubular battery. That being said, I think you need another installer to check what the other installer did on the roof.

If the 8kVA is of the Felicity hybrid type, and the VoC of the solar panel is below 50V, the 7 panels should be connected in series. Before this is done, the installer should check each individual solar panel to confirm they are okay. You should get at least 2.5kW from this setup if positioned on the south-facing side of the roof, and the roof inclination is not too steep. The best roof inclination angle is one that is almost flat.

Dam5reey1:
They are reliable, however, 30-400V MPPTs, are less efficient compared to 120-450V ones

But that wider range is an advantage too 😀

kristien4:
Anyone has any idea on any good servo stabilizer, bought prag 30kva, and it got bad within few months, has anyone used himel or Mercury brand of servo stabilizer??

Try Stavol.

zenith4biz:
The guy should have consulted, he can get 3000w pure sine wave inverter on nairaland for that amount even on AliExpress

Chinese are masters on deceptive advertising. They know how to hide details by careful "omission". They paste pure sine wave everywhere on their pure sine wave inverters, and then on their modified types they don't post anything. Crazy way of doing business.

vicarsenal:
My TEMU order of a 3000w Pure Sine wave Inverter took 13 days to arrive at my pick up station in Ado-Ekiti.. TEMU means business... Kudos to them. Paid via bank transfer.. Just easy shopping...

zenith4biz:
This not pure sine wave inverter

Ok. Thought as much. Thanks

vicarsenal:
That's the pictures

Price: ₦105000

Wow, this looks cool. Also you may need to recheck if this is truly pure sine wave, because from the little I know of China and their antics, is when they "omit" some details on a package just know that package may very LIKELY be lacking the attribute.

Notice the absence of "pure sine wave" anywhere on that package? That may deliberately mean this is not one. Anyways you just gotta crosscheck and confirm if this is the case.

Please if no trouble, kindly share a picture of it. How much did you get it?

HeavenlyBang:
Doesn't that depend entirely on the specifications of the MPPT?

Emm... did you read the part where I asked for the max VoC of the MPPT?

kristien4:
@all, pls what guage of wire should be used for 100amps dc current, for battery to inverter. Can 16amps cable work?

I'll do at least 50mm²

Teophilus96:
My findings is that my Felicity MPPT is not set well, I believe. The controller reads my battery as full, whereas the PWM keeps charging it because I was able to set it better.

My panels are 3parrallel connection of 200watts panels. It’s a LifePo4 battery. I am not just getting the settings of my MPPT controller yet. Can you help?

Especially with the Absorbtion voltage and Float voltage. It’s not like I don’t know these things I have set the values appropriately (14.4V and 13.6V respectively) but they didn’t help. I have tweaked in a lot of ways but still experiencing the same thing.

So what I do now like I saw someone here do too, was use the MPPT to charge it fast to that point where it will no longer charge the battery, and then continue charging with PWM for full charge and then connect back to MPPT for proper voltage regulation. This is what I’ll keep doing till I get it right.

But I’ll really appreciate if you can help me as well as I have seen you have such a vast knowledge on these things. Thanks.

MPPT tends to perform better if connected in series. If you mentioned your MPPT max VoC and your solar panel VoC that could help. PWM on the other hand tends to perform better the closer the PV input voltage is to the system voltage.

fuckboys:
he didn't start using renewable energy today, HE CURRENTLY SWITCHED TO A LIFEPO4 BATTERY probably after previously using some older battery technology.

Oh, that's even cooler.
