[quote author=ojeysky post=87403864]The same to you my brother, that's why I shared the URL so you can order. Stuff I ordered since Jan on AE are still enroute [/quote
Every Chinese seller these days use coronavirus as an excuse not to ship or to explain away slow shipping.

Looks good, buy and review for us

NiyiOmoIyunade:
This is why I am partial to products with local support available and also always keep a backup inverter on hand since I have severed my connection to the grid and have no generator assist.

If I had to buy and import a GK like you did, I would buy + replacement boards and other components.

Always a good plan to have a backup inverter.

Dude says Coronavirus things did not let workers resume in factory o. They don't usually pre-fabricate these batteries in warehouses. They get to manufacture them when you place orders. The guy don order tey tey, but as Corona no gree people go work, he is still stranded.

Reason I'm likely gonna opt for the 9ja manufacturer option.

Coronavirus strikes again! The virus is really dealing with the world's commerce and industry. Let's hope we see the end of it.

ceaser:
Be likely getting it from the same supplier that I got those 12v LFPs from once his consignments come in March/April.

How did it go?

ojeysky:
Yes you can but I don't want to....I like to keep my usage within 90% and 10% DoD. Actually once your battery is below 3.12v per cell you would have already taken out over 80% of the juice in the battery.

Ok. That makes sense.

ojeysky:
There are 2 things here:

1. Low voltage protect of the BMS, if and when this happens the BMS shutdown power from going out of the battery hence your inverter won't even come on. The idea is for you not to get to that stage by doing point 2 below, but if it happens, the rest button or hoping that a high solar current will be sufficient to wake up the BMS are the options

2. Voltage cut-off by the inverter, if this happens then no issues as the inverter is what has stopped output hence your battery still have juice in it and will be ready to receive charge whenever it comes up. I recommend this and currently have mine set to 24v.... unfortunately that is the highest cut-off voltage that I can set on my inverter (and I think this is applicable to most inverters).

You can hit up to 2.5v per cell with no issue ie 10v without issue if it's a 3.2v lifepo4 cell.

Will sell at 39k and 41 for 350 and 360 respectively

Ok. Thanks

Phone that computer villages boys will unlock within 30minutes, it will be more easier over there na.

Do they unlock it with data on phone still intact?

gouken2:
Why can't u guys check his phone for all his Nigeria contacts

How many people use their phones without passcode?

alramon:
believe this at your own damnation


chargers give out 1 to 3 amp which is not enough to even shock let alone kill....shock starts from 30 amp

30A won't shock you it'll burn you!

SUPERPACK:
I suspect murder or suicide here. How can a 5v USB electrocute a grown up human being, something I even put in my mouth. Even if the charger goes bad such wound looks out of it. Waiting for professionals to throw more light on the matter.

It can kill. What you did not realise is the circumstances that it can kill you. For instance, do you know whether there was a thunderstorm while he was using the phone? If the house is not earthed or the electrical earth is bad, if there was lightning strike as he slept, it can kill him especially if the charger is faulty or failing. This is the reason we are advised to ensure that our house have adequate thunder arrestor and good electrical earthing.

Most are still looking for the price, so I'll ask on their behalf, how much?

Man cannot even take a selfie in peace again

quest4s:
Done that several times
Disconnected everything connected to it reconnected again and powered it. Same thing
Even waited for an a hour at some point. Yet same thing.
Started yesterday afternoon.

If under warranty, you may need to consult the seller about the issue.

quest4s:
Problem not solved

Inverter still works fine.
Charges battery with power supply
And still powers all my appliances
But shows the Service Assistance indicator light

Disconnect and reconnect the battery.

ojeysky:
The image did not display but I guess you are referring to the same guy? Yes indeed. My personal quest for DIY is because I want a BMS that can provide me status of each cells. I have also recommended it to him, hopefully he will add it in future.

The image was only referring to here https://www.nairaland.com/390522/solar-energy-complement-fta/670#86587802

adrusa:
So, when are we going to see serious local dealers? Buying from China is a logistic nightmare.

This guy is good too, I know someone who bought from him and there's no complaint till date, ojesky can also testify too

ojeysky:
It's like you just experienced some new stuff about lithium.....was charging my battery was charging as 48A yesterday with a smile. Lifepo4 is cool, even if what I get from it is 5 years considering the performance I am getting I will still be fulfilled.
Planning a DYI Lifepo4 soon to increase my battery bank capacity.

That is one of the advantages, the ability to charge at supersonic speed and high current without fear of damage to the batteries. Lithium is just the future.

If you are still undecided here is a piece of advice, going lithium from lead acid battery is like upgrading from a horse ride to an electric vehicle.

quest4s:
service assistance light showing on luminous inverter. What does it mean?

What's the capacity, model and DC voltage of the luminous inverter in question or is the problem solved?

Bigdocemo:
Pls I Need Ur Help On The Next Step To Take. I Ordered For An Item ( Samsung Note 4 Ba3 ) On Aliexpress Jan 2nd Which Was Shipped On The 4th, Today Is The Last Day Of The Deal To Lapse. No Information Of The Item While Tracking On 17track, I Don't Really Need The Ba3 Again Cos The Phone Is In Bootloop State And I've Tried To Flash It And Yet It Didn't Come Up. My Question Goes Thus: Should I File 4 Dispute And What Are My Chances Of Winning D Dispute? Moreso, D ATM I Use In Paying 4 D Other Expired Last Month. How Will I Get The Refund I Case I Win The Dispute?

Yes, you have a high chance of winning

ojeysky:
No I have not, looking to ride on your experience first ni o
I took a quick look on the spec, it says 4A max current yet on the description it says maximum power 750w. That does not seem to add up.

Chinko just dey copy and paste specifications without regard to what is being sold.

feflo:
No sir

Ok, thanks.

Do you sell adjustable charger that can be adjusted say from 0v to like 60v?

LordGuru1:
Ok, pls send me the online link.

Here is a cool portable charger, good thing about this one is that you get to choose the voltage and current of charging. You can choose the 0-36V 28A option.

LordGuru1:
Boss, good morning sir. Where can I get the following soonest? I urgently need a 24v Lithium Battery Charger or transformerless 24v Inverter that quickly charges 24v 200AH Lithium Battery.

I don't know where they sell such in Nigeria.

spartacus11:
100Ah

Ideally, most lead acid batteries are recommended charged at C/10. That is 100AH should be charged at 100/10= 10A which is a rule of thumb rule as some can take higher current, that is where smart chargers comes in. So in your setup it may be good or bad depending on the battery chemistry and the behaviour of chargers used.

spartacus11:
Boss Dem is it advisable

I'm currently using 2 separate charger to charge a single 12v lead acid battery

Nepa go soon seize like and i needed a quick charge

Will this damage d battery

Suoer 1000w with inbuilt 10a charger is connected and foxsur 12v 8a are the 2 chargers that are currently connected to the battery

What's the capacity of the battery being charged?

What happens to buying a black contact lens?

Ok na, time to show the world your "cure" I hope it won't go the way of the HIV cure by some people in Nigeria that never saw the light of day.
