NiyiOmoIyunade:
Does this imply that you tried to use one PV array with two different charge controllers at thesame time? This is a very bad thing to do - I am struggling to understand why the PV voltage on one CC affects the performance of another CC.

You can have as many CCs as you want connected to one battery bank so long as the battery can safely absorb their combined amps output. But you should never connect thesame PV array to more than one CC.

In my case I have 4 independent PV arrays and charge controllers connected to my battery bank. I may add a fifth CC soon.

I'm very sure he doesn't imply connecting one panel array to drive two CCs simultaneously. That's one of the basic things one learns not to do on the journey. In fact the wiring of one array to 2 CCs will be one I can't wrap my head around.

I think he meant that the the ipowerplus and PowMr both have their independent array, but the panel array for the PowMr exceeded that allowable for the IpowerPlus but within the acceptable limit for the PowMr. The resultant error was only corrected when they were forced to reconfigure the PowMr array, sacrifice it and therefore underutilize the 150v voltage limit of the PowMr to allow for the 75v ipowerplus not to be confused.

Speaking of which I actually bumped into a YT video of a hybrid inverter with two different CCs installed inside it and the two CCs receive their input from two different arrays. The output AC of the inverter is split phase into 120v (in two places) so that if you are in regions with 100v to 120vac, you just connect to one phase but if you are in Nigeria for example you connect the two 120vac phases across to get your 240vac output voltage.

I'll see if I can retrieve the link.

ojeysky:
No he was not using the inbuilt CC of the hybrid, the hybrid was just serving as normal inverter.



This should indeed be normal behaviour but in that particular case it didn't work, and since ipowerplus is somewhat is being talked about I thought I should mention that experience.

Edited. I see you've responded. But how will the ipowerplus be misbehaving if the in-built MPPT is inactive? That doesn't really add up. I tjought the in-built MPPT being active with an external MPPT on one battery will be the same as having two different CCs charge one battery.

[color=#0000ff] Except you're not using AliExpress Standard Shipping! If you're, 95% of sellers will use SGP [/color]

I don't think that is very correct. For an item, options for shipping listed can be but not always:

• AliExpress Standard Shipping
• Singapore post
• DHL, UPS, FedEx or TNT

All at different shipping costs.

So if they are both listed differently and at different prices too, how can AES now mean Singapore post?

Cos if the seller lists Singapore Post for free shipping and AES for usd1.20 and my choice of AES on which I paid the extra is changed to Singapore post with the excuse that they mean the same, I'll definitely file a trade dispute sharp sharp.

Was it COVD related?

dapsyra:
Just don't try it! I have one that I pushed to the maximum power about a year ago. It rewarded me with the proverbial magic smoke. It still power-on but can no longer make power

I'm actually not acquiring two extra CCs for fun. That'll make five units in total. I think I'm expectant of whatever it throws at me from the experimenting. Don't see me as a destroyer o

@bolded. By pushing to the limit, do you mean that you overrated the voltage going into the CC or the amp from the panels? If it's the amps, by what margin did you go?

ojeysky:
If they are both going to the battery terminal and the voltage for ipowerplus is maintained for the CC then it should be fine. I once had an experience with a friend's setup; the powmr we got allowed more than 75v but because the mercury hybrid can't do more than that, things went south until we kept array within the mercury hybrid CC Voc

Thanks. This is informative.

Is there a 24v 3kva wall hung?

spartacus11:
I love this wow. See enjoyment this is PowMr cc right, how is the performance which version is it?

PowMr no get version releases bro.
They just dey produce dey go. I fear if they decide to go the version way, it'll be a way to increase the price whereas all those version thingy na just a sweet-mouthing method to increase price.

MakeSkyBlue used to have fair prices like powMr with their version 113, but as soon as they begun their version 117 and 118 WiFi wàhálà their prices doubled that of PowMr.

Funny enough the two manufacturers are always at each other's neck one branding the other as making inferior imitation.

I own the two types - one 60A MakeSkyBlue and two PowMr. They are same form factor but with slight variations in info display and recently the inclusion of WiFi capability in the version 118 of MakeSkyBlue. Also when MakeSkyBlue reaches float, the screen blue light brightens up and the displayed info repeatedly alternates between battery voltage - Panel voltage - Temperature - load power. PowMr does not do that.

Performance of the two is at par in my opinion. On price, I don fashi MakeSkyBlue tey tey.

In fact, two weeks ago, I placed an order for another two units of PowMr 60A in prep for 48v upgrade. Now 32k including standard shipping due to covid19-dollar synergism (used to be 25k). I paid around 7k more for expedited delivery via DHL as standard shipping has been negatively impacted with Corona problem. MakeSkyBlue tops at 70k each.

PowMr 60A is available on Jiji and Jumia for around 45k.

mahkanjuh:
Pls, kindly help retrieve that link you talked about

I'm so sorry. I thought I had posted the link sometime ago, or maybe I did but the bot as usual did its worst.

It's available on Konga and apparently there has been some re-designs since I bought mine 3.5 years ago.

Try and beat this.
3s2p 280w x 6 yingli panels @ noon
Total 1680w installed capacity...harvest 2035w, it even hit 2045w..but went out b4 i could take a picture.
Next step would be to verfiy this readings with a clamp meter, cos i had about 34.6amps coming in @ 57.6v or so

@bolded: The war of the panels

And I can't ignore the lovely PowMr.

I'm waiting for the day I'll push it to the max with 48v battery set up. Right now one is on 12v set and another on 24v setup, both firing well.

ojtech8291:
Yeah... The VOC of the series connection is a bit higher than that of the CC.

Bhet why nau?

You know you shouldn't exceed that CC voltage. Abi you dey try experiment ni?

ojtech8291:
Stopped charging until I have to off and on the breakers. It happens every time the sun is very high.

Shuo! Na wa o.

Does that happen with most MPPTs or it's just a peculiarity of yours? What's the brand by the way?

mctfopt:
Chat with the seller to actually verify that the $60 is inclusive of shipping to Nigeria, and that they can sell only ONE piece of the item. Many times the sellers are reluctant to sell just a piece even when they stated MOQ (minimum order quantity) of 1. I've bought one piece of item from Alibaba, but I had to chat with seller first and seller asked how many I was buying (seller actually has MOQ as 1) and it had to take some convincing to get seller to sell that 1 and also we negotiated shipping price before the deal was sealed. Alibaba sellers are a different specimen of sellers, most of shady ones will want you to take the conversation to WeChat or WhatsApp (you will have no evidence if deal goes south if you agree), always insist you have neither so all communication will be on the Alibaba portal, also only pay with Trade Assurance order so that you will have buyer's protection, the payment methods include:

1) Credit Card
2) TT
3) Online Bank Payment
4) Online Transfer
5) Western Union
6) Pay Later (for only US citizens suspended for now due to the world's economic downturn brought by Covid19)
7) Boleto

Note: If you pay via a method not on the list or directly
to supplier's personal account, the order will NOT be
protected by Alibaba.com Trade Assurance service.


Alibaba in my opinion is more flexible, I've gotten a seller to locally source for items not in their store and the seller was able to do that for me saving me extra cost in shipping that item from other stores as the seller consolidated the items. You just have to be patient to negotiate, get them to send you a PI (proforma invoice) take some time to source dollar (for big dollar payment you can always approach bank to dollars with the PI, bank can then wire to an account produced by Alibaba to effect the payment). I think it's fun to do all these

FYI: majority of sellers prefers shipping to a forwarder in China. The reason is simple, they get to get their money very fast. So get used to saying "I don't have a forwarder in China" when chatting with them about shipping and they ask, " Do you have a forwarder in China?"

Oooshey! Tuale.

Inverter is 24v

Hmmm. The familiar PowMr MPPT.

Did you take delivery of this pre-covid? Cos I got two units stuck in shipping till now.

spartacus11:
Do you still recommend this pure sine wave inverter, i need a pure sine wave majorly bcus of my home theater i hate that sounds it makes on a modified since wave. Hope its wave is truly pure and will work well for home theater

The inverter is a true PSW. And a good one too. If AC power is good, it charges well (20A charger I think). It has a lot of battery, load and output info on the display, but unlike some in its category, there is no way to turn the various displays on the screen off.

iKingsley:
Hmm... Ecobank sef! Was charged at 1x403 now refunded by 1x380

Is a dollar now 380 naira?

Ecobank has scammed you my guy. The fair deal is to be refunded at the prevailing exchange rate which is definitely not less than 390 naira as at today.

Edit: Sorry for the double post. I used Glo.

I just won my dispute this morning,
I'm using this opportunity to thank everyone that helped,
Thumps up

99 USD. Well that was not a small money to ignore.

ojtech8291:
I will amend it seems affecting the battery charging. Thank you.

Perhaps with an appropriately sized busbar, that your circuit diagram will be feasible.

Firstly, the fact that the BMS LVD feature always sets in implies that the battery is experiencing some abuse from the user. For your pal, by the time the BMS LVD triggers, battery voltage is likely at 21.6v (2.7v per cell). It is better not to run in below 24v or at worst 23.8v (2.7v per cell). That way, he may be able to get a high cycle of use at that DoD. Note that even at that his 21.6v DoD, he may still be able to get some 6 years of use, but with 24v he nears some 10 years. Ditto increased years for DoD greater than 24v. Frequently deep discharging the LFP will make the cells to quickly get out of balance even though a BMS is present and the long term effect of that if not corrected is that some cells in the pack get stressed more than the others, them rapid degeneration.

Secondly, there are LFP assemblers that give the option of installing a switch on the enclosure that you can press to do the reset. But if you choose that option, you risk losing the warranty on the pack because to that assembler, that means potential abuse which voids warranty.

Thirdly, your friend has another option of waking up the BMS - charging with generator. Solar input may not push in enough initial current to kick-start the BMS, but an external AC charger will surely do.

Finally, that battery should not be habitually discharged below 24v to get your max cycle of use outta it. He can get an external LVD device to control the battery output to the inverter or if he can afford, get an extra LFP type to share the work with the existing one (connected in parallel).

mctfopt:
Who can help my friend solve this problem? He has an LFP with 24v 60A Daly BMS common port. The problem is that whenever the LVD is triggered, it does not automatically reset when charge flows from PV (say the next morning when the sun comes up) unless manually bypassed. By manual bypass I mean using a short cable to connect to the battery's negative and to the point where the BMS solar charge controller negative and inverter terminal battery negative meets, in simple terms replacing the BMS with a short wire. Is there a way to make this automatic? For instance in a remote site, it is expected that the inverter comes up by itself (if it the batteries drain at night) the next morning when the sun comes up. But this behaviour will make such a scenario not play out.

gidieberry:
What exactly is Singapore Post issue gangan, this na unregistered mail handled by Yanwen but handed over to Turkey Post Unregistered
cc:jboixxx

I noticed something similar with a supposed DHL logistics. Track24 shows Cainao handling it. A possibility is that Caino handled the item from China Mainland to Hong Kong which is where the tracking currently is. It's probably Hong Kong DHL that will handle logistics from there on.

I want to be patient to see the change over the next few days if my suspicions are true.

Damdammy:
Please help me out, for the past 23 days tracking remain like this on track 24. Should I be worried though on AliExpress I still have 31 days running....

Also, on AliExpress it shows the second image. Pls how can I contact support team in AliExpress?. Thanks

If it's Singapore post, as the tracking suggests, you may be in for a long haul. I placed some 5 orders over the past 10 days and realized late that I had selected Singapore Post for four of them, (4px I think is Singapore). I did it absent mindedly and I'm still crossed with myself for that error. When my eyes opened, I decided to cancel one of them that was yet to be shipped and which fortunately also had more expensive item.

Those ones shipped had been crawling for the past days. . The second screenshot shows my order handled by 4px that has spent 61 days in transit, yet no sign of tracking update no signs of it was gonna he to me.

isgombe:
Which tracking site shows town of final delivery?

Track 24 does. Even 17track showed Kaduna as destination in one parcel shipped from a fraudulent seller like that.

By town of final delivery, I mean the post office town address nearest the address you dropped.

mctfopt:
The leads of a BMS are often rated according to the charging current capability. Eg if you have a 50A BMS and you push 120A through it, the lead wires will most likely melt or even the BMS enclosure itself! This is because the cooling factors may obviously not be in place for that high current capacity. I've experienced this.

@ bolded
Oh! Well experience na master.
Na theory level me I still dey.

Rajioba1:
Oh okay thanks

JESSE2:
So what will i do nw?

You may have to wait. Just hope that the system updates promptly within the next one week so that even if you don't lay hands on it in the next 5 days, you'll at least be sure of the final destination within Nigeria. If the update shows the final destination for pick up as your town, then it's 95% sure that the parcel is yours and you should wait for PO to contact you or you visit them yourself.

On the flip side (rare cases of useless sellers), the pickup town may be updated as another state far from yours. That is 90% probability that it was indeed meant for another buyer in Nigeria. The remaining 10% probably due to NIPOST delivery error.

Rajioba1:
Aswear I tire.... Does it mean it arrived Nigeria and refused to update

According to the screenshot, it has already reached Nigerian soil - INSERT ITEM INTO DOMESTIC BAG. They will want you to wait to receive it. Sadly the BP has ran out and in case you do not eventually recieve it (which may be due to lost item in transit within Nigeria or it was meant for a different address within Nigeria), it'll be too late to open dispute after 15 days has elapsed. Even disputes for delivered but damaged items, wrong items, false description or substandard/fake items which will be valid if you prove it well may be too late to open if you don't get your order within the next 7 days.

When items are taking too long for delivery, I usually generously ask sellers for BP extension of not less than 30 days at a go. I have nothing to lose if I receive the parcel a day after the approval of extension, and in case things go south, 30 days is long enough to pull any strings with the seller before I go the dispute way.

At times along the line, the seller may promise to re-send the item. If I'll agree to that, I usually give the condition that the seller first extend BP for the current item in dispute, then ship another one with correct evidence. Then I cancel the dispute. Meanwhile the BP for the two will now be running concurrently. Within few days, I should be able to decipher from my end if the tracking number he provided for the new item is indeed valid and destined for Nigeria.

So either way, it's still a win win for me.

I opened the disput some minutes b4 BP runs out
I attached 3 screenshots from different tracking site

@ bolded
Most likely that was the culprit. Either the system registered the dispute at the exact time you filed it or an representative picked up the case earlier than usual.

ojeysky:
Yes but that should only the applied with small banks else one may use one kidney to buy BMS , if you have a over 400AH bank then you don't have to look for a 400AH BMS because the reality is that you won't generate or consume up to that amount of current instantaneously. So for 150AH and above a 100A BMS is fine. If you get higher at a good deal, all well and good

I've often wondered if similar BMSes can be paralleled on the batteries, like you would do with CCs.

ojeysky:
It should do either of what you have stated above or just limit charging to the peak and continue charging. That's what mine does, it stays at 60A max charge without any trigger but since it's solar charging which is not constant, I don't know how it will behave if I had e.g 70A constant current on it, but documentation says it will trigger over current protection

I think that your 200A LFP with 60A BMS might be really limiting. My 24v/100A has 60A BMS and I'm still seriously flirting with the idea of yanking it out.

What has prevented me so far is fear of voiding the warranty. Once I've enjoyed it for a while, I will definitely do it cos that urge is nagging. I think next time I will insist the dude slaps in a higher rating BMS for a few extra bucks. Maybe even supply him the BMS of my choice sef.

garbamaza:
Good morning all,
Gurus in the house I need your advice on this 24v, 100 ah lithium battery with 10a BMS.
Thank you for the possible responses.

Who puts 10A BMS on a 24v/100ah LFP?

Please read the buyers' reviews to be sure the rating is truly 100Ah and not 50Ah or 40Ah sef.


In addition, there are Nigerian assemblers of LFP that will offer you a 60A/80A BMS with that battery rating for around 280k. I even think that Felicity LFP will cost you less than what's in that picture. Remember that shipping fees, which might be approaching around 150k with dem DHL UPS et al, will still be added.

Then when it gets to Nigeria, customs will still cut their own pound of flesh from you. That might be around another 15k to 25k.

ojeysky:

He said the BMS will burn out if the battery is exposed to a higher than rating current.

I think in such instance, what the BMS does is to shut down (activate overcurrent protection) rather than burn out.

Or am I missing something?

You will wail for long. You cannot work in UBA and then go to GTB at month end to ask for Salary. You cannot contribute 5% to a government and expect to be treated same as those that contributed 97%. Even our LORD Jesus said "I am coming and my reward is with me, to give everyone according to his work". Anyone that does otherwise like robing Peter to pay Paul, will end in hell fire

What percentage of our earnings is from crude oil again? Yeah, I know Kaduna and Katsina are major oil producing states in Nigeria, so they truly deserve to collect the "salary where they contribute more".

Even something as big as NNPC built mega hospital in Katsina is fairness and justice in my sincere opinion.

At times I like when people have fun playing it with their spouses or children. I've also heard it kinda improves reflexes and mentation. But I can't seem to bring myself to consider playing it or even consider it a worthy investment or acquisition.
