How much is the Daly BMS with BT? Were you offered locally in China? I won't mind guineapigging it.

$160/$170 for 200A 8s and 16s plus around $50 freight and PayPal fee

Okay this one is 4S, I got the BMS-ANT which has a wider range.....now waiting on AliExpress to deliver

Oh, you later got that ANT version. Cool. This one has other range, just not as versatile as the ANT. But many that bought this says it rocks. Let's hope it'll enter Naija just as we wrap up lockdown

But since nothing is coming in now, what is the point in buying? Why not wait till this is over. I thought you had a local seller. Thanks.

Things are coming in. You just don't get to see access it. Some of these things can't be sourced locally, you just don't have option but to buy it outside. So, dependent on your level of acceptable risk, you can buy now and collect whenever they call off the lockdown. These products will take up to five weeks to get here. Do you think the lockdown will extend to that time? No one really knows, but I'm sure they'll be riot if it continues the way it is for another five weeks.

Panel is 18k at Alaba, I learnt. Original panel is 45k but how do I identify "original" when stickers can be placed on a Chinese panel and sent to you as Canadian panel? So I decided to stick by my inferior panel. Isn't it serving me? I got the panels high but later got direct link to a seller at alaba. Be careful, though. A "friend" got the first two for me at 23k each only for me to realise it is sold for 17k when I got direct link. I got the last pair for 39k per pair excluding shipping. There are several sellers on this platform. I have transacted with a few but some are that are "evil". As my law lecturer will say, caveat emptor, ie--buyer beware.

Get your panel in pairs, there is something called panel mismatch. I'm sure gurus in the house will shed more light, and reasons for it. I am a novice but an unrepentant DIYer.

Browse mercurydirect.com.ng for current battery price. It is 112k presently. That is 12v elite battery.

Thank you so very much Sir. I've learnt from you, and thank you for the vivid explanation

It's one OX fan o and one Rechargable Mist fan. The OX is not the industrial type though, it's the normal one, is that the one you are referring to? Any idea on the watts?

Can you recommend standing fans to use?

My current fan (OX AC 230V 50HZ 70W) makes a very loud annoying noise whenever I'm on inverter (Mercury 1.2 modified sine wave with Luminous battery)

Your inverter is not pure sine wave that's why. Not all equipment flow well with modified sine waves so it's better to improve your inverter to pure sine instead of buying another fan.

I seem to be in the same shoes, got a 12v 4000w pure sine wave off grid inverter from Jumia global, but on testing it the noise coming from my TV speakers was something else. But once I change it back to grid power or my prag inverter the noise disappears.

I'm contemplating returning it back to Jumia and getting a refund, but I need to be very sure before doing that as all my fans are DC fan and I don't have any coil based equipment to further test and confirm.

Can anyone advise on a means of confirmation to know for sure it's pure or modified sine wave.

Attached is a picture of the said inverter.

The inverter is not pure sine wave.Get rid of it before it spoils your TV.I had similar issues when I was using Mercury modified sine wave.Humming noise from my Samsung 43'' TV and ceiling fans.The TV eventually developed issues.Just go for truly pure sine wave jeje!!

Thanks for the recommendation, I'll try to get a pure sine wave instead. Wish I knew this before buying it though, I'll probably end up with an inverter I'm not using.

As omotoda pointed out, I believe the problem is with inverter, probably best to switch to pure sine wave.

It's unfortunate cos I actually wanted a pure sine wave inverter and it has a sticker of pure sine wave boldly imprinted on it.

I have a 1500w capacity of a similar Chinese inverter brand that works well. This is just unfortunate. But if I can't get a means of confirming the true sine wave of the inverter, I'll just return it and count my losses.

From comparing your picture to images online, what i saw says your fan is ox standing fan "sf-1618". If that is correct, then your fan is 56 watts.

As has been said earlier, modified sine wave inverters are not the best. Aside technicalities, the characteristics humming noise is always a problem. I will advise that no matter what a seller says, do an independent review of hat you want to buy before making the purchase. Many sellers come to my place of work to advertise varied products; all i do is check the product name and details, pick up my phone and verify the claims of the seller against what i am able to find out. Then i will begin to ask him questions. I patronize aliexpress a lot but before i make a purchase, i look at review of past purchasers of the product. I was once tempted to buy an inverter like that but after asking questions, the seller introduced another product that is a true pure sine wave. It was more than double the initial price. But i also learnt the hard way.


70 watts for a standing fan is on the high side to me. While searching for a low wattfan to buy, i discovered addrakk, qasa, century and boscon. I settled for boscon because it was the best sturdy wise(why buy fan that doesnt look strong and sturdy?) Qasa has lower power consumption(33watts)but doesnt look strong enough compared to boscon(40watts). Its blade is 18 inches as against 16 inches that is common. It was advertised for 22k-24k online but I got it for 17k haven connected to seller at alaba. Will post picture later.

Get qasa AC/DC fan. Max consumption is ~26watts

That is 16 inches blade. Its 18inches blade consumes 33watts. But boscon is better in terms of stability, sturdiness ans aesthetics though it has higher power consumption at 40watts for same 18 inch blade. And it id rechargeable with 12v 4.5ah battery.

Reasonably so but could be better. You already bought it so unless you want to dash it out or you have large storage space, then you are stuck with it for now.

My problem with most of psw inverters is the high self consumption, I use a msw souer 1000w inverter whose self consumption is around 8watts thereby making the battery last very long compared to a normal inverter. Maybe it is also because of the ferrite core transformer in it compared to the iron core in most of the other inverters that is the determinant, I have also been using it with my electronics for a little over a year with no effect albeit humming from the ceiling fan which is bearable. Which brand is your psw inverter by the way

Not really an answer, just sharing.

I got to know a reputable seller on Alibaba from a Solar forum and the cells have been tested to be full capacity by multiple buyers and were recently confirmed to be manufactured by EVE a reputable battery maker.

These prismatic cells are 3.2v 280ah at about ₦33,000 each, so around ₦264,000 to make a 24v 280ah ~7Kwh battery weighing roughly 45kg.

The issue is shipping.

I chatted the company about shipping cost and their rep advised me to wait till miday before making any purchase as shipping prices are very high at the moment due to covid.

But I estimate shipping to cost between ₦90k and ₦150k, depending on if naira regains or losses value and if global shipping costs drop back down

So everything would be ~₦390k give or take ₦30k, plus a BMS @ ₦25k

Alternatively there is the Felicity 24v 200ah ~5Kwh battery which can be gotten locally at around ₦340k ~ ₦350k, need for BMS.

But I haven't really seen any review of it.

So my options are 7Kwh @ ~₦415k ± ₦30k or 5Kwh @ ~₦345k

EVE is also a good product, like prismatic CATL.

If the alternator has been changed to a good one then the issue may be somewhere else. Just incase attached is how to disconnect the alternator from power supply. You can do it at night, if your level remains the same in the morning then it's not from the alternator. You then need to trace via the fuses. Here is a good URL that explain that process, it can take as fast as 5min or as long as a couple of hours depending on how fast you detect the culprit.

Thanks bro. I appreciate.

NiyiOmoIyunade:
I have been thinking about implementing a config like this for some time to save on upgrade costs and also just for the heck of it.

It should work reasonably well if you use the PylonTech to drive the system - one source of control.

The other LFP bricks are just connected to the battery bus with no comms between them and inverter or GX.

I would oversize the other cheaper battery bank a bit to allow for quality control variations and so that the PylonTechs never discharge into the generic battery e.g match 48v 400Ah of PylonTech with 430 to 450Ah of a generic LFP

@ bolded makes a lot of sense.

How about his load? Are his appliances energy efficient? eg. He may not be told by his installer to switch to energy efficient appliances. I remember someone talking about a customer not willing to do away with a 600watts TV. Why use 100 watts light bulb when 5 watts will serve same purpose. Implication is I will use the energy of your one 100 watts bulb to light 20 rooms at 5 watts. Dig?

And for those shouting lithium lithium, I forbid you to mention that name on this platform again until I save enough to buy it. Stop intimidating me else I will send the anti spam not after you or invoke village spirits to block sun from shinning on your panels. Lol
Enjoy, my eyes are on you. Meself go join you later than sooner. 350k no be small money, I never recover from lead acid.

lol. Badu belle
I pray God gives you the financial strenght soon to hop on the lithium wagon.

Hopefully the lowering price keeps its trajectory and naira does not further plummet against the dollar. And of course may vendors not flood the market with fakes so that the lithium experience is not bastardised for everyone.
