Hello ladies and Gentlemen please clear the floor for team Induction cooker!!! Well just to chip in my little contribution for those using non stick magnetic pans please pay attention when it ages or coating start to pill off its very dangerous to the health it can course cancer. If possible just buy the plane still or stainless pans. Respeck all….

Yeah, stopped using all my non stick cookware this year. I'm now team 304/314 stainless steel cookware. Health is wealth. Crazy you'd see old nonstick cookware, well peeled, on sale as Tokunbo in Nigerian markets. Knowledge, they say, is power.

Gshems:
Please guys I need suggestions for a 48v 5kva inverter and 5kw lithium battery

Get a 6kva Growatt inverter so you can overpanel in the future.

Get LVTOPSUN 5KWH or any of Valto, Reed or Deriy Battery

I love the Chinese. Sometimes they don't just give a fück about aesthetics. This is someone casually using BYD blade cells (15kwh each) and even built contraption to get it hanging off a wall

Flies wire as if he had once worked for NITEL/NEPA.

Anyways it works, that's all that matters

Famicare 3.5kva/24V with inbuilt PWM Solar Charge Controller and 2units of 220Ah Tubular battery available for sale. Total Price = N600,000.
Location: Ibadan. (Suite 54, St James Cathedral Shopping Complex, Labaowo Ogunpa, Oke Bola, Ibadan).

Is the tubular battery new?

AyarmBoye:
i understand as all the loads will be using the power the solar is generating….

I’m hardly at home during rhe day so no loads ….
My question is what if the battery get full before I return home I hope the charge controller can cut of the supply to avoid overcharging of the battery? And what happens to the power the panel keeps generating when the battery is fully charged?

The answer to all your question is actually in the name of the device- a solar charge controller. It literally means it'd control the charging coming in from your solar panels. That means once battery is full, it'd enter float (stop charging and maintain a particular pre defined voltage).

...but by the time they hear the PRICe tag, dem go jeJeLy like the sound of the FaN

😂

You have a point, premium products often come at a premium cost.

Don't be surprised that there are low frequency inverter that consumes lesser idle current as low as 20w. Make ya findings

My 4kw Schneider no load draw is 40w.

Growatt 5000ES hybrid has a no load draw of 45w.

Some LF inverters are not that wasteful.

ask4bk:
Some of these old inverters stay completely silent in normal user except when it hits like 50% of rated capacity and the fans activate.
But these new ajebo hybrid inverters will just have fan constantly on even on low load, and will increase the fan noise with more load hitting it.

These old inverters are just so robust and working for 5-7 years without any single fault

The old inverter don't usually multitask and form factor is usually bigger. Cramped in electronics deserve ventilation

Newer hybrid inverters does three functions...charge battery via mains , has a solar charge controller and inverts. All these generate heat, making that fan necessary, but if you hate fan so much, some premium inverters are out there with huge heatsinks and no fans eg Goodwe, Solis, Sigenergy etc

brightk:
Are we neglecting the amount of energy in these banks? u are converting from ac to dc, where are the losses in ur calculation....

I never knew that charging phones consumed so much power until a friend opened a charging shop near school. He runs at a minimum of 600W even on days when there aren't many phones. With 78 charging points, the wattage adds up pretty fast. He currently uses two old 220Ah tubular lead acid batteries paired with four 550W solar panels. Eventually, he will have to swap out those old batteries for lithium ones.

tziz:
Wow. Will 25mm/sq work?

16mm² can work too, you asked for the ideal size. Ideal is 35mm². But if you have 25mm², go for it.

tziz:
Please what's the ideal cable size to use from battery to Inverter for my 12v 1.5Kva Haisic Inverter?

35mm²

waleayeni1:
Fair enough. You appear to be a very diligent student of DiY, judging by the neat arrangement of your setup. I have sent you an email. Please share your WhatsApp number for a closer collaboration if you don't mind. Considering going for the bigger panels (725w) but the weight I see of those things are scary. Make e no go bring my roof down. Plus charge controller that would give me peace of mind no go cheap. With your help, I am more assured.

715w panels are pretty huge and heavy (37kg)

But it's all good.

It works ok. Just get a tier one panel: Jinko, Longi, Trina, etc.

xtremeidea:
Hello Guys, please what Voltage protector do you guys use? i got one Joyelec like this and it's not cutting but allowing voltage over 240 pass through. i have done the settings multiple times.

Try POSMITH.

You may get lucky. If all failed, get a servo AVR and call it a day

waleayeni1:
Thank you for the prompt response. This your setup is too clean. Are you by any chance an installer? You are my lastest favourite person on nairaland at the moment. Abeg permit me to be your curious student at this time. What is your Solar array strength. What is the size of your battery bank. Is there any part of the system that you wish you had done better? What is the relative cost of the components used outside the inverter? I would be ecstatic to get your feedback

My solar array ain't that much. Just 9 panels. 4 nos Jinko 380w and other random 5nos 250w panels. Battery is 14.3kwh, I built it myself. I like to DIY things...with enough patience you can do virtually anything....except, maybe, surgery on yourself

I wish I could add more panels, but sadly I can't.

Tdoctor:
This setup is beautiful. Where did you get the wire pipes (the name just fled my head)?

AC PVC duct pipe, a leftover of a big job done by a friend.

waleayeni1:
Thank you for your support thus far. It turns out that the 4048 i got is bad. Do you know any trusted repairer in Lagos that can assist to fix it? Also. please i would appreciate it if you can snap and send your setup so i can replicate with my SW 4024.

I don't know of any other trusted repairer unless you'd visit Schneider head office in Lagos at Ikeja Off Adeniyi Jones 1 Tunde Gafar Close. I'm sure you'd get info on repairs there.

isentropic:
Guys,
I just installed 12KVA felicity inverter with 15Kwh felicity battery.12 X 440W jinko panels connected in series to PV1 and 10 X 590W jinko panels connected in parallel (5-5 in Parallel) to PV2. The inverter has an inbuilt mppt so no need for external charge controller.Anything to be worried of.Just seeking opinions incase I missed something

Isn't that 12 panels in series close to 480v for the panels in series? Or am I missing something here?

Are you not better off connecting the 590w all 10 in series? That should be about 442v. Pretty close to the 450v which I think is the closest you could safely get to these 450v-500v high voltage hybrid inverter.

Been almost 2 years I got my parcels routed via NIPOST. Is this luck or what? The NIPOST friends I made sometimes call to check on me. They are wondering why they no longer see me around. Nowadays it's just me and Speedaf these days- maximum of 20 days wait time on almost every package. Well, lemme not jinx it

Diamondroyal:
Please does anyone have idea about shipping cost to return an item (tablet)back to aliexpress preferably through speedaf.
Thank you.

Has Speedaf starting shipping things TO China?

I doubt they do.

Try other option like DHL, but be ready for their cutthroat prices.

hardeycute:
i think i prefer having my view like this than having someone post irrelevant long epistles.

GarkiAccessory:
Boss long time
It's been long I place order on AliExpress

Please how do you guys get around the the high prohibitive free shipping fees?

I buy things more than $10 so I somehow enjoy their "free shipping" which I'm sure is still factored into the price of the goods.

HawkTuahGirl:
You people funny sha.

You can buy panel as high as 150k. Every solar system that make sense is within 1m and above.

To pay a working man 10k is now problem.

Nigerians hate to pay blue-collar workers, even those who could afford it. Oya na DIY they won't. They are always out looking for who they'd pay a slave wage.

A friend of mine studied biology in the US, but his skills range from networking to renewable energy. He has more tools and expertise than most professionals because he actually took the time to learn how to do it himself.

A typical Nigerian wouldn’t do that; they’d rather call an 'expert' and expect free labor. It’s wild how some of us operate.

That's a big move. Job well done.

Congratulations to the owners.

Encitee3991:
Not supporting such reviews, but comment on delivery issues is part of product review. Only that many are more concerned about their shipping experience rather than actual product
There are 3 main aspect of order review.
>product rating
>seller communication
>shipping experience.

Bro, that's the only review they give!

That's the ONLY thing they often say.

I like that you can talk about ship time in review, but making it the only review is now something I see often in Nigerian review. Nothing about the product they bought.

Olamak1:
Imagine!
The person in the screenshot actually received his item, yet decided to drop a 3 - star reviews for the store simply because he was yet to test the product.

What he should have done was to confirm receipt of the order immediately and then wait for 2 or more days before adding the reviews (by then, he'd have been through with the testing).

I’m honestly shook, bro. How did he even find time to drop a 3-star review when he hasn’t even tested the thing yet? It makes zero sense. I keep seeing reviews like this from Nigerians - stuff like “It arrived late,” “It arrived fast,” or “Don’t use NIPOST next time.” None of that has anything to do with the actual product! So now, people like me who actually want to know if the item’s worth buying are left guessing. It’s kinda sad - like, five of my countrymen left full-on blank reviews and I still have no clue if this thing even works.

Abeg make una dey leave better review

SolomonGrundy:
Thanks. When the charging stops the AC disappears, then it tries to reconnect back again.

Above setting should help

SolomonGrundy:
So, I did switch it to Li, immediately I did that, the red light (fault) started blinking. Reverted the settings to USE and it returned to normal.

Oh. I see. There is no communication between your battery and inverter.

Action: Change Setting 03 to APL (Appliance).

19 Bulk (CV) Voltage 28.2V Charges cells to ~3.52V (safe, full charge).

20 Float Voltage 27.0V Maintains battery without stress (~3.37V/cell). If this issue continued after this setting, change Float to be the same with Bulk voltage (28.2V).

21 Low DC Cut-off 24.5V

Quick Question: When the charging stops, does the "AC" icon on the screen disappear or flash, or does the battery icon simply stop moving? Knowing this will tell us if it's a voltage stability issue or a software setting issue.

SolomonGrundy:
It's on USE type. But i don't have the parameters. Also, i checked the settings and I saw that maximum utility charging current was set at 20A. Is that okay?

Set to Li

Charging utility current at 20A is ok

SolomonGrundy:
It's a 24v lithium phosphate battery.

Yes, it recognises mains, but immediately it starts charging with mains, it automatically disconnects. And the cycle repeat itself until I put off the mains breaker.

I have no idea. How do I access the charging profile settings?

Ok.

Setting 05 Battery Type

Set to USE (User-Defined) to manually enter voltages.

Other options: AGM, Flooded, or LI (Lithium).

Select Li for lithium

SolomonGrundy:
Thanks for the response. I just checked now and this is what I saw. Seems it's already on that SNU. Pic attached

What type of battery are you using?

Does the inverter recognize mains input?

What is the battery charging profile settings?

SolomonGrundy:
Good day everyone!

I have a little challenge with my growatt 3kva inverter. Since I installed it, it has refused to charge my batteries using the grid, so basically I only charge using solar. However, considering the raining season is almost upon us, I wanna get it fix ASAP.

Anytime I connect it to the grid, it does connect quite well but as the battery is about to start charging, it automatically disconnects. I've tried it several times, but the issue still persist.

For context, the grid supply voltage reads between 230 - 240, therefore it's not a case of low voltage or high voltage.

Pls, does anyone know why it refuses to charge?

Check Program 14, I think, in Settings. These are the priority settings:

CSO (Solar Priority): Uses Solar first. Grid only kicks in when the sun is down or too weak. (Best for lower bills).

CUT (Utility Priority): Uses Grid first. Solar only acts as a backup if the power goes out. (Best if solar is very limited).

SNU (Solar & Utility): Uses Both simultaneously. Charges the battery as fast as possible. (Best for unstable power areas).

OSO (Only Solar): Uses Solar only. The grid will never charge the battery. (Best for 100% off-grid setups).

You may likely be in OSO which only allows for solar charging. Change to SNU
