The item has not been shipped. Any suggestion on how to avoid the high customs duties?

What kind of goods are you shipping?

Which country is it coming in from?

These two may determine the answers you get.

rkarang:
This is also my concern. The seller told me that if checked by customs I may be asked to pay duties. This is obviously too much. My item costs around this amount too.

Which courier was used to ship the item?

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

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

Mjolnir:
1. YOUR BATTERY may have been full
2. fake panels
3. wrong cable size
4. pv spec exceed pwm cc acceptable specs.
5. fake/ substandard pwm cc

No 6. Display could be wrong. Get a clamp mater and cross check.

I've never appealed a card twice since I started buying things on AliExpress because my appeal is granted once I submit it.....

Your submitted information may not be detailed enough to warrant acceptance of the appeal.

As per delay in cash withdrawal from Bitnob card, you can chat their CC up.

Never had to appeal a card. If na juju, my own dey work wella. I just buy and it goes. No appeal. I funded my bitnob on first try with $400. Used it to buy things on Alibaba and no issue. I wonder what triggers this appeal thingie. Must be absent in my account.

I hail all our great solar gurus here.
I want to join the solar train now.
I already have a 4.2KVA 48V Genus inverter system with 4 units of 12V 200Ah Genus tubular batteries .
The next steps is to add panels and MPPT and the rest.
From what I have read here, I don’t want to over- invest and have wasted voltage capacity or underinvest.
I am buying Jinko panels from Fouani because I can access at dealer price.
I have options of 475W , 550W, 580W or 625W panels.
My installer is recommending just 6 panels to be connected in 3s2P.
Please which of the solar panel wattages above do you recommend I pick.
He also recommended 60A cc MPPT ( but I am thinking of 80A). Kindly advise

Buy as much PVs as you can without going into debt. Get a 120A charge controller for ease of future expansion. Thank you

Hybrid600:
Who has installed solar for something like this before?

What kind of solar set up will be able to power an ice block machine with 4 units of 2hp ACs ?
Each AC is estimated at 1500w and will be used during the day when there is no power and sparingly at night.

Get 60kw of PV and 120kwh of batteries. Then you are good to go.

Olamak1:
Yes, they don't!. One of the reasons I stick to them!
It's an amazing platform for now.

The other day, a message popped up on the bitnot app where they were mocking the likes of Chipper cash and Grey for charging maintenance fee.

I also remember the day I opted for their virtual card, I was surprised to see that only $1 was charged for the card, though I had already prepared my mind for $3.

They are the best for now. Just made some pretty big funding with no issues with less fees. I'll be leaving Klasha as their cost is not friendly at all.

balogunsam:
Makes sense. So is your recommendation to trim down to 4x 180w panels? The main need is just to be able to run the small fridge and computers and fan during the day. Or the fridge to run on battery overnight while computers and fan runs during the day.

Reduce to size the controller can handle or buy a bigger controller to accommodate more PV.

Obviouslyblunt:
an inquiry, do they take monthly maintenance card fee? This is something chippercash started from nowhere.

To the best of my knowledge they don't

EduTechTainMent:
You mean you exceeded the maximum wattage rating for the cc?

In his case with a 60A cc, the maximum PV wattage supported should be (12V * 60A) 720w. His installer fed the cc with (180 * 6) 1080w from the panels.

Is the cc a pwm or mppt?

In some controllers, you can exceed the maximum rated wattage with no damage to the controller, but the issue is that the excess panels are just there doing no job. Eg if the maximum rated by a 60A controller @ 12v is 720w and you have 1200w PV connected to it. At most what you'll get out of it is that 720w, the remaining 480w PV is just there outside doing no work.

jakjohnny:
How much to get the card?

$1 to create card and $1 to fund less than $100 and 1% if more than $100

adibo:
Also, I am caught in two minds, between buying a 2.4kva 24v mercury hybrid inverter and buying a 1.5kva 12v Mercury hybrid inverter. I need it for lights, charging of laptops and phones, 120w fridge, 240w washing machine and 32 inch smart TV. I heard that 24v inverters are more efficient than 12v inverters. Also, I am just considering buying the 2.4kva in order to have extra space for more load in future. What is your advice?

Dear Professionals

I need to design system for 240kw, 20kva Inverter - Out door enclosure for lithium LifePO4 battery

Which brand will you advise on batteries, Inverter and other components (I was thinking of felicity because of their presence in Nigeria incase of aftersales support and warranty.

Thanks

You are better off sourcing cells and DIYing the battery side of it. You can always source inverter here.

I'd advice guys to be careful with this person. Must you spam the thread just because you want ro render assistance? In fact, with what you'd done here, you must have got a skeleton in your cupboard. If not, you'd know that a single post is enough to convey your message.

For this, you've committed a ban-able offence!

The guy reminds me of all those "customer care" guys you see so much on crypto twitter comment section with @gmail.com email addresses spamming comment section luring noobs to contact them to retrieve lost crypto. Lol

He forgot we've been on that space for so long seeing scam baits is just another day.

adrusa:
True, but some low life inverters will not shutdown gracefully, they will blow a few mosfets if overloaded. I wonder why?

Their life is low.

redgem:
But if price of dollar should go up, you'd still sell old stocks at new price right?

This is just basic economics, not like I'm selling anything. You don't expect people with old stock to suddenly drop the prices of goods bought at ₦1700/₦1900 simply because there is a ₦200 drop in the price of dollars.

TechGeek777:
Nice, I pray dollar continue to crash for massive discount.

Other vendors should review their prices.

1350 now for $1.

Oh yeah, but old stock must be sold before the review

Boss, even with large bank, lead acid battery can still be properly charged and managed very well.
Once you get the basic things right, every other thing takes care of itself.
This issue of comparing LA battery with the Lfp has been discussed extensively some years back in this forum.
George_D has large LA battery bank and he has used it for about 6 years then. Maybe, it's up to 10 years now.
He's one of the founder of this forum and I really learned from his knowledge and I'll always appreciate him.

With regards to George D, it is pertinent to note that big banks of lead acid battery in series is a different ball game to big banks of lead acid battery in a series-parallel connection.

Also the inverter with this combo too plays a big role.

That said, I would not personally recommend big banks of lead acid battery where the energy needs is high.

But as they said each user should know what works best for them, but in my experience the need to use LA battery (especially for a 12v LA battery) where the energy is high is not something I would recommend, especially for 48v system and below.

Obnoxious2001:
Location?

Anywhere in Nigeria is cool.

Have anyone have a good metal fabricator that can build custom designed DIY battery box like those in this attached images?

isangjohnson:
There is nothing wrong tubular batteries. I've a friend who has used his for 5 years now and they are still waxing strong. He bought them from the right source and he's baby sitting them as well as derating the capacity he's using...
Some people love buying products they're familiar with while some like going for new innovation....
It's a matter of choice.

In small capacity say under 6 batteries, I see nothing wrong too. But if you really need energy to require up to 20, that's where I'll recommend going lithium. I've seen cases of this type of system dying way before their time due to issue mostly related to charging. Most of these large banks like this miss out on proper charging. Going the lithium route would've been a better alternative when you need energy this huge.

Hello.. @all... my growatts 5kva inverter has a max of 22amp(Isc) can i connect it to a pv array of 28amp(isc) since its amps not voltage, and just expect it to extract its 22amps from the 28amps array without blowing things up?

It won't blow up, but I'll tell you what will happen. If the panel is producing less than 22A everything just works normally, but when the production peaks above 22A the inverter will enter error mode and shut down. This can happen as many times in a day until you reduce the input current to less than 22A. So, it is recommended not to exceed the voltage or current rating of the inverter.

Get an additional growatt inverter and connect both in parallel or get an external charge controller to handle the excess PV panels.

My first lifepo4 was gotten in 2019. Battery is still kicking. Dunno if I'll get 3000 cycles, but the performance appear to be the same as in 2019. No regrets.

Still kicking
