How much is your 24v and 48v packs?

zeestone99:
Oya come and buy original 400w talesun tier1 solar panel. E no reach 50v

@bolded. Shey you meant to type "E no reach 50k?" Lol.

I believe 2s will be best for the 400watt panel given that the VoC approaches 40.8volts. That makes 81.6v A 30v headroom for the MPPT to charge a 48v system isn't bad.

So this item that has remained on Speedaf-Nipost since 18th September eventually got delivered today 19th October. It was a small parcel and guess what, the post office expectedly billed me 200 naira. So annoying.

Now it seems the logic I tried to theorize about speedaf-nipost alliance restricted to destinations outside the domicile of speedaf offices, this assumption appears to be false.

An item that I purposefully changed the destination to a town with speedaf office has shown "speedaf-nipost" status in the tracking. And I have about 10 more orders that I have changed the address to the new address on based on that assumption that they're gonna escape Speedaf-Nipost.

So what I am led to belive right now is that speedaf and Nipost randomly share speedaf parcels among themselves for the final stage delivery in order not to let the latter go into obsolescence and irrelevance resulting from poor service delivery.

Sadly, their middle name still remains "inefficient", otherwise they wouldn't still deliver an item one whole month after it got to them and they wouldn't bill me 200 naira for an item that is tagged as "ordinary parcel".

iscom:
I don't think they are original. Though you can verify them.

I have my suspicions too. But the version 2 that I bought has good reviews and from use for few days now, I think it is the deal.

For the version 3 though, one can't tell until I lay my hands on it.

100 million naira thief is talking.

Lai "La-teef" Mohammed is his new name.

deepdeep:
Feck on the alter.....that must be a most high feck

Lai "Liar" Mohammed being a thief is bad enough. But now adding theft to that is absurdity taken to new heights. Stealing 100 million naira is unenviable.

But can one escape not seeing new absurdities every passing day with Buhari's minions? No.

Now his new nomenclature is Lai "La-teef" Mohammed.

ojeysky:
My 390w has Voc of 48v so it's safe to work with that as the for the 400w

Your system is 48v system and your panels is 2s config, yes?

ojeysky:
Where is the nameplate ratings?

I've not even spotted any nameplate of those panels. But if 270 Watts can have around 35v VoC, I'm just imagining what those ones will have.

earthrealm:
IfVoc of those panels is more than 50v, then stick to 2s..if less 3s. i actually dont see the comparative advantage of those 500w panels. my sweet spot for panels is 300w to 350w, its portable enough to fit in a big suv and not too heavy to maneuver during installations

I think I'm with you on the bolded. Except of course I am ready ti get a pick up truck to ferry them. Then get a very experienced installer to mount those large weights.

ExtraUniqueGuy:
I received a notification this morning from AliExpress that my order has been cancelled by the seller. Some moments later (barely 1 hour), I received a SMS from the post office to come and collect my package.

I have collected my package now (the fastest order I have ever received, I made the order on the 24th September). Thank God I didn't open any dispute.

As in the same order? Is AliExpress system malfunctioning?

But technically I suppose your money should be automatically refunded if the seller cancel it, same way it happens when the buyer cancels his/her order.

Edited: I guess the coupon is the reason the order was cancelled by the seller. But it must have been too late before he cancelled it, already shipped maybe.

Abeg, how una dey get 17k, as 17 thousand naira, coupon? . Tisha, Teach me.

Abeg, make this country just divide immediately I tí North and South. The south has nothing in common with the North.

Someone analysed that looking at the world map, there is synergy, synchronicity and similarity more with regions along the same latitude than with regions among the same longitude.

For instance, Benin Repuic, Southern Nigeria, Cameroon, Ghana all have more in common while Niger, Chad, Northern Nigeria, Sudan all have more in common; while it isn't the case if you're looking at it from North Southwards.

Penuelseun:
It's another one, the cell build phase gets easier with each build

@bolded. This is true.

You should see how the build version improves with each subsequent pack.

The last two packs saw the incorporation of nickel strips, spot welder and fish paper. Thinking of adding a knife fuse or glass fuse and also brainstorming on including communications port with subsequent builds. Of course the latter will mean upgrading from the current BMSes.

Is that 48v pack? And did you use resistor wire fuses for the positive poles of each cell?

earthrealm:
Progress was made by those who choose to think/see/do things differently.
I urge you to ignore the nay sayers and put this to test.....

Its a cheap cc, if it fails the test.we would have gained knowledge as a community�, and you use the oppurtunity to upgrade to another cheap ass cc..powmr that has VOC of 150v @ 48v setup.

How accurate is the voltage reading of the cc?. It might be off by a few point + margin of error. Extra 5v shudnt fry it

Talking about VoC, with these recent 400 Watts, 440 Watts solar panels flying around, how many of it do you think will be in series to handle a 48v set up? 2s, 3s?

Thinking of including those in the array, so I have to be sure before I fry those CCs.

Also @ Ojesky, @ Níyì.

ojeysky:
So for 16s it's 16x5000?

ewizard1:
Yes sir.

Ha! Odiegwu

genius43:
I heard $200

I couldn't go above 150 usd in my last transaction. But maybe they subsequently increased it sha. This coming month will confirm that as I will have a monthly limit refresh by then.

nani667:
It isn't important enough for me to go through the stress of Journeying to their office

Plus I don't even have the time for such Journey.. I will get my refund if they cannot deliver.. I will contact them first about the delivery tho


Meanwhile, Is there a way to avoid Speedaf when placing orders on Ali ❓ I would like to avoid them next time if possible

The reason for return will be documented as "buyer rejected the item", and I don't think that will boost your buyer ratings on AE (buyers also have ratings like sellers do and sellers avoid transacting with buyers that have poor ratings).

Also if your shipment is not "free shipping", the amount refunded will be short by the amount billed for the shipping. That is, only the cost price (minus the shipping fee) will be refunded to you in this instance.

So weigh your options.

There is really no way to avoid speedaf except your item is shipped from Hong Kong or Singapore (where speedaf currently don't have presence); in either case, your shipping option could be Hong Kong Post or Singapore Post respectively.

But if it is AliExpress Standard Shipping or Cainiao, there is high chance it will end up with speedaf.

And speedaf isn't so bad by the way. Your tracking number clearly ends with "O" which indicates ordinary parcel (as opposed to "R" registered). Most likely ordinary parcels do not get the doorstep treatment that registered gets, although I am forced to believe that speedaf initially handles all parcel as doorstep delivery and may have just effected this policy change in recent times.

DOMINO001:
Hello everyone.
I ordered for something around May but I didn't get the package from post office till around August.

I applied for a refund which was granted. Just last week I received a call from post office that my parcel has arrived. I went there and realised that the parcel was there all these while.

The issue now is how to refund the store. I contacted them and they sent me a link that is only $0.1 but the initial amount was around $5.

I want to ask should I include the 0.1 and the 5 dollars and pay?
Pls I need your input. Thank you.

Select that link and choose multiples of the "item" until it adds up to 5 usd. Then you can go ahead to check out.

dahflemzy:
Good day here.
Abeg has anybody ordered for Lenovo earbuds/inpod/earpod from AliExpress before or has anyone here used Lenovo earbuds before.
How's the sound quality and battery life.
Is it better than those inpod i series.
Which one will you recommend
I see alot of orders on AE plus it's a budget gadget and ion even know which one to order.

That Lenovo cost seems to be on the high side, so I tried out Redmi earbuds (version 2) which is around 4k. It was delivered via speedaf in 2 weeks and for about a week now, its been going on fine.

The bass isn't bad especially if you are able to set the equalizer on your device. The connection can be via one or both earbuds and connection is instant the moment you bring the pod outta the case. The button only controls pause/play, no ff or rew. The bud fits the ear tightly such that ambient sound is shut out. No USB cable was included in mine though, but I think that was the package I opted for.

I'm looking forward to trying out the version 3 which is soft touch button, more colour options, waterproof, ff and rew options, USB type C charging port and of course more recent. It goes for between 6k and 9k depending on the store.

dejidotun2000:
I have had one for about 8 months. I have no real complaints but I can't help but wonder if it can really handle the 60A it's supposed to be able to handle. It's cheap and serves my purpose.

Well, I make it a tradition not to max out the stated capacity of these solar products when I use 'em, either premium or not.

So all my 60A POWMR has peaked at 50 amps at most. When I need more power, I simply get extra. So I have two each per set up.

Oshomo12:
This will be lovely to find out from your research!

Note: You will see more than 36 v from those panels.

I am not advising you to do the connection with 2.5mm, at least, there will be a voltage drop along the wire. so you MAY NOT see up to 100v.

BUT why now? Do you just feel like frying something?

Lol @ bolded. As in?

Na now their day break.

Legis-looters, una good morning o.

When Nigerians dey shout say Buhari bambiala don dey become too much, the useless leader of the rubber stamp NASS talk say na everything Buhari bring dem go dey approve.

Officially confirmed. Yesterday I was able to place a 149.99 usd order on GTB card and it went thru.

I believe their limit has been upped to 150usd from the previous 100usd.

elvischukie:
mine has been stucked departed country origin

If it is "speedaf" tracking number, you should try tracking it thru cainiao website. That is the place to get tracking info on speedaf items when they are still outside Nigeria.

cell7:
Pls how reliable is POWMR mppt charge controller. Who amongst us has used it?

I have had POWMR in set-up for the past two years. Some others here too have it in their set ups. None of the four has shown any untoward issues.

NiyiOmoIyunade:
Sorry I am late to this party. I typed a response but the NL bot swallowed it.

You want a device like the XH M611 as your best solution (find it on AliExpress) - I have found the inverse logic of the second device CDxxxx a bit unwieldy.

My advice is to not modify your inverter on/off switch in any way. Simply power the LVD device from your battery bank, and use it to energise a relay/contactor that disconnects the inverter AC output once the LVD setpoint is reached.

The sequence is battery bank - LVD device - relay/contactor - inverter AC out.

You need to select a relay or contactor whose coil voltage matches your battery. I use a cheap 48v DC 5a relay to energise a larger 220v AC contactor coil - if you go this route all you ever need do is change the relay to a one with a suitable coil voltage for your application whether 12v or 24v or 48v nominal every other item in the BoM stays thesame and keeps things simple

Thanks. I really do not mind this route. However one reason I ignored it is that the inverter still runs even when the AC output is off, meaning that the idle consumption still continues.

Okay, let's assume I want to adopt your method (which I really love to), what contactor would you suggest that can handle at least 16 amp of AC power output at the inverter AC terminals?

I will look up that XH M611 right away.

So for those that have speedaf tracking number and their tracking info gets stuck at "reached destination country" or are getting "no data" on speedaf NG website, I think the problem is that speedaf NG did not update the tracking info for that period.

I have such parcel that I recieved from speedaf office on the 10th

Screenshot on the right is that of the AliExpress tracking status info showing item stuck at "reached destination country" while that of the right is on speedaf NG website which replied "no data".

harkinlaby77:
Chiefs in the house, please a seller wants me to make an order without paying but each time I try to make the order it always direct me to payment page, how do I bypass this?

Enter the correct card number (if you enter the wrong one, mastercard is able to immediately tell that the number is wrong)

Then enter the correct expiry date (reason as same as above)

Finally, TYPE IN THE WRONG CVV2. But make sure it is any random three digit aside from your correct cvv2.

Then click on "save and pay".

Your bank will decline the transaction based on wrong cvv2, and the item is transferred to your "cart" to your "unpaid" folder.

Another repressive policy. Thanks to the d1ck-tator in Aṣọ Rock.

Shebi it's NTA?

Don't worry, it will be full of lies.

eleojo23:
Hello everyone. Been a while.

Please how does one achieve low voltage disconnect (50% DOD) with an inverter that doesnt have it built-in? Is there any good external device for that? I saw something like that on AliExpress but the circuits are so small I wonder if they are practical.

Quite practicable.

I use this for 12v, 24v and 48v inverters. Although you will need to do a very minor extra wiring on the main switch of the inverter.

As per the 48v system, you are already nearing some high voltage, so the alternative connection will have to employ the use of a DC-DC buck converter to energizer a 12v or 24v relay or you use an outright 48v-72v relay.

omotoda:
From.my amateur knowledge,look for a charge controller,the typical PMW should do.Connect it to the battery and set the charge controller LVD to the desired voltage equivalent to 50% DOD.I think that should work.The charge controller will cut off load supply at the set voltage.The experts are here to advise professionally

Perhaps his set up doesn't include a PWM controller. Also most available PWM and MPPT controllers don't provide the wide variation and flexibility of voltage based DoD values that one will desire. The controllers for instance have DoD settings that range between 10.7v to 11.9v

Also, except you have a controller or a battery protect device that can handle the high amperage that accompanies current movement between the battery and inverter, you're not likely to be able to utilise that route (battery to inverter connection) to achieve your aim. Reason why you adopt the main switch of the inverter (with a little modification)

Attached are the devices I have deployed.

The first one is my favourite because it only trips off when the voltage has remained below the preset DoD for 10 seconds. So it has about 10 seconds delay before it trips off in case the drop in battery voltage below the set point is due to the momentary surge of the device (eg freezer, pumping machine or heavy appliance) placed on the inverter.

The second one has the advantage of being able to show battery percentage and count discharge time parameters (which I don't think I need) and also the screen goes to sleep (depending on your settings) to reduce consumption, which is very minimal in my opinion. But it does not have the delay option of the first one. The instant the voltage drops below the preset DoD, it trips off.

The connections is made in such manner that these devices take over the factory switch terminals of the inverter while this factory switch remains in the off position. You can override the devices "on" control simply by manually switching on the factory switch of the inverter.

While it has worked in most cases, I experienced a challenge with one of the inverters that has maybe logic control which registers on the screen of the inverter. It occasionally records the last "switching off" by the meter an as error, I guess since it wasn't done by the factory switch. So when it automatically turn on again (by the meter) , the "error" previously recorded logically/internally turns off the inverter after a couple of minutes. The inverter comes on again (this time by itself cos the meter is already locked to the "on" position) and then off again after couple of minutes. It can repeat this twice before the logic finally agrees with the meter (rather than the inverter factory switch) to perform the switching on option and then it stays on.

The inverter is permanently running 24/7 but I usually encounter that problem occasionally during the rainy seasons when the batteries are not well charged and the inverter had to turn off at the preset DoD.

As said earlier, in about three other types of inverters without that logic intricacies, the set up works perfectly.

Since 17th Sept (last month) my order have been stuck with speedaf-nipost, finally I received an sms today from nipost to come pick up my order. I went there to pick it up. Speedaf-nipost marriage combo is not working. They should divorce biko

jikins:
Item ordered on the 26th of September, received today 7th Oct. Roughly 11days. Omo this speed is fire. Seems speedaf aren't in Osun they handed it to a local logistics company kc logistics who delivered it.

I agree with you.

It seems speedaf's alliance with private logistics pays better than with grossly inefficient NIPOST.

Yeah. He will pay off the prison officials and they will get an innocent man implicated and sentenced to stand in his lieu while he walks away free.

He is believed to be a mole for the FG, hence the high level of suspicion.

Once he gets info of the attendees of the meeting, he may relay it to the FG who will now unleash the DSS disguised as UGM to take 'em out.

The DSS guy killed by the police in Imo aroused suspicions of being a trouble maker and as one of the UGMs. He should have simply told the police that they have the same master and that he is on official assignment from the FG to carry out "some strategic security jobs" (if he can't mention being a DSS cum UGM), and perhaps he would be spared.

Mace0lane:
You can wail ll you like but Hope will be winning his 2nd term election when the time comes.

All the tricks in the book have ready been played for his first term realization by the Fulani.

The people will be waiting to plug all the loopholes this time; except the FG brings in a whole regiment of the Nigerian army and the murderous DSS to intimidate the people.
