Any real life experience from anyone who has used any 5000BTU window unit air-conditioner?

Anyone got a link where I can buy a portable (300w to 1000w) pure sinewave 12V transformerless inverter with charger function?

ceaser:
I'm only working at probably importing one, not DIY yet. I feel the imported could serve as a pedestal for future DIY.

When you do, remember to buy the one with a good motor (Bafang, Bosch, etc). And of course a good battery pack (Samsung cells, etc though you can DIY this part).

remizvxcq:
which Washpap group? kindly share.

Very interested in EVs. These will be the next accomplishment of the solar cadres. All that excess afternoon solar going into your transport!!
Then go bigger, and set up a charging station for your neighbours.

Africa will shock the world with adoption of affordable EV especially bicycles (mountain bike style for all terrain), keke trikes (for commercial taxis), and scooters (for neighborhood runs if you have smooth roads). Let me know if you want to make a business of these.
You are not alone. You are ahead.

Me, I no get money for isho, i dey plan ile-ala ja gogoro!! And not gogoro the Asian battery swap e-bike mobility business, either.

I've gotten two ebikes, we like to go renewable all the way

My WhatsApp group comment is just a way to say the brands I mentioned have similar pricing and sort of similar specification, not a real WhatsApp group.

I run a single 1.5Hp LG AC on my system. The AC is located in my bedroom and it works in bursts of 1, 2 or 3 hours, maximum of 6 hours per night. I tend to do more of 4 hours than 6 hours. I have a total lithium power of about 600AH and I'm not shy of pushing it down to as low as 30%.

You are a man after my neighbour's heart

Dude likes to push everything to its limit. The 600AH is it running at 48V nominal voltage?

litaninja:
Chai! Baba, cut Lithium for me na!

You can do even more. If you want to. Chinese making it easier by the day.

NiyiOmoIyunade:
At that time I had 48v 800Ah of Gel batteries, PV array was 7.56Kw.

I have been looking at an electric bike called a 'Rungu Kilimanjaro' - something for recreation and exercise but with enhanced stability (2 front wheels) - I am a bit of an extreme sports fan - ride quads and jet skis a lot.

Rungu is rugged, I'm thinking of getting a RadRunner

The gel battery you've got then was pretty huge. That's why I often don't advise people to run their ACS off their smaller systems.

NiyiOmoIyunade:
I have been nearly 100% offgrid over 6 years and running ACs off my system for ~4 of those years.

The system performance when using lead acid was average, I would get a little over 2 years from my battery as the battery was deep cycled daily with 2 ACs running almost 24/7.

Now that I have ported to Lithium the experience is far better - 18months 100% OFFGRID running 2 units 1hp ACs 24/7 and another 5 ACs opportunistically off a 48Kwh Pylontech bank and the batteries have performed outstandingly - no discernible degradation, no capacity loss and cell level state of health in excellent shape.

You really have to size the system appropriately viz number and wattage of panels, battery size and BATTERY TYPE - certainly Lithium batteries do far better in high discharge rate applications - with proper design, I was able to dump all my inverter ACs in favor of standard ACs so I could enjoy better cooling performance - so a trade up in all aspects for me - everyone's situation and mileage may vary though.

With all the ruckus about Deye inverters, I could not help but pickup a new 8kw unit as well as a couple of new Lishen 280Ah cells to try things out - once I have the system integrated into my existing one, I will be in a position to run at least 4 1hp ACs 24/7.

By now, I have run out of spare internal organs to sell to afford Lithium so I had to sell off some Pylontech bricks to finance the Deye inverter and Lishen cells.

I find that most folks do not really run their ACs 24/7 or overnight - on average you would need about 1kwh of battery storage per 1hp standard AC and about 600wh of battery storage per 1hp inverter AC if running overnight (you get better mileage if you allow the inverter units run continuously). Day time use you need at least 2kw PV to run 1hp AC and size up to 4kw or more if you need to replenish battery capacity that was spent overnight to power thesame AC.

The ugly truth about offgrid living with high energy consumers e.g. ACs is that you will likely need a generator from time to time - the premium inverters like Victron incorporate a power assist feature so that you can use the smallest possible generator size e.g a 5kva generator to drive a 15kva inverter AND automatic Gen start/stop based on SoC, battery voltage and AC loads so that the Gen can run the minimum possible amount of time - you can even set exercise hours so that the Gen battery and internals stay ready for use any time.

Thank you for this super detailed response. I may just get me some Deye inverter as they have been in my cart for so long.

When you ran off lead acid battery, which size of battery did you use that needed change after two years and what was the size of the PV system?

I understand the need to run off regular AC as I've noticed that you trade performance for low energy when you go the inverter AC route.

Lishen, CATL, EVE all happen to be in the same WhatsApp group for most DIYers across the world.

I have another question for the house, is anyone here into EV or at least the younger bro electric bicycles/scooter etc? I hope I'm not alone here. Lol.

Valto:
guess it is 32pcs eve 280ah cells.. the 310ah should be CATL...

The 310 is CATL...you know your Chinese

kolagbemi:
Hello guyz,

Please i need your advice, i recently ordered vehicle parts on AliExpress and one of the stores I bought from has some other parts I needed.

Now I want to buy from him again but the items i want to buy from him are not listed on AliExpress and he's not ready to list the items on AliExpress....he said they don't use AliExpress for such items with lots of money. And as naija man wey don learn in hard ways, I am not ready to send over 1m to someone I don't know beyond whatsapp....

please how can I go around such transaction. I urgently need the parts.

I've pleaded he list the items or allow me pay via PayPal Buyer Protection but he rejected all. He wants only direct transfer and 100% payment before shipping.

Please what should I do....do we have Nigeria companies in China who help in this type of transaction.

Do we have individuals who can intermediate between me and the seller?

Please help guyz.

My major fear is fraud....make him no carry my money run.

Try Alibaba. Use third party shipper to ship your product. Good luck

ojeysky:
280w X 9 - Sunfit panels
380w x7 - Prime panels

Both are made in china...Deye inverters has started showing up more in naija....I know someone locally who now sells 8kw for 860 to 880k

Your neighbor Sabi be that. Those looks like 280 or 300ah cells. You both Enjoy!

That's 280AH, he ordered 310AH again. In lithium we trust. Lol

dejidotun2000:
At least two people on this forum do, niyiomoiyunade is one of them. Check his signature to see his setup.

Thanks. That's good to hear. Abeg others running AC on their setup should please contribute.

ojeysky:
I run 2 ACs, they are both thermocool 1.5hp, one is inverter AC and the other is normal. I currently have 280AH LFP 48v (not the nominal voltage) with 5.2kw PV and a Deye 8kw. They serve the household appliances not just the ACs

This is awesome to hear. The 5.2kw PV is it premium make or just Chinese type? I do see Deye online, didn't know they make really cool inverters. My neighbour just had these bad boys delivered.

TheSoothSayer:
I just got the edifier tws1 Pro yesterday. Delivery came early from Jumia. The noise cancellation (passive) is second to none, Even without music playing. You'd like it. The sound quality is a bit too treble bright, but can be easily toned down with equaliser. Battery is cool 12+30 hours. The only downsize is you should never use it on a busy road. Last night a bike passed beside me and I didn't hear it, only saw it when it came to view. Another problem is that it creates pressure in the ears due to the seal it creates, but I'll get used to it. I hope

When you try the active noise cancellation of the Edifier NB2, you'll realise you can't use two and still maintain any conversation.

ekesonbatteries:
...

Is EverStart not car batteries? You can always specify so one don't buy it as a deep cycle battery for renewable energy storage purposes.

tetralogyfallot:
Have them in large quantity.

Are these batteries new?

Beware of some posts in this thread, scammers are here baiting prospective victims with tall tales of how they made millions in a day. Just be very careful of who you PM or contact privately. My 10 Kobo

slizzyb:
Pls what does it mean that my order is with last mile carrier, is it talking of post office? Cus mine is stuck at that since 29th last month. Should I go to post office??

Not bad to go. I have a shipper that did not inform me my goods are in the country. I was passing their warehouse when I decided to go in and ask if my package has arrived, it turned out my goods has been there for the past two full weeks with my numbers clearly noted on it. So you can imagine what can happen when you move packages on the scale of NIPOST, one item must slip through the cracks and no one will inform the recipient to come and collect it.

Uchman81:
I just de read things here from page 400 I'm really scared,
I want to order a 1:1 copy of the airpod pro from Alibaba and I need it within 15days, can you guys please recommend a courier service that can receive the item in china an Ship to naija within 15days.
Help a brother.

Use a third party shipper, most will tell you it'll get here under one to two weeks, but just keep it at the back of your mind it may take a month.

sofiscatedmoron:
Why all these on almost all my orders

I got same update but still got my item in under a month.

Olamak1:
Thanks for the update. I was about asking question on this.

You are welcome.

Valto:
my aliexpress payment rate 465/$

Smartmanager:
You mean any Master or Visa card would do?

Yes

Smartmanager:
Hello. What type of card do AE accept for payment? Thanks.

MasterCard or Visa. Verve don't work for international payment.

sofiscatedmoron:
There are rumours that aliexpress logistics to nigeria will be handled by another logistic companies and no longer aliexpress, due to nipost slow nature,

Source?

globalfanz:
Safeplux is something else. He can run for some of the time but not all the time. He must surely take responsibility for his action one day.
I mentioned it here so that prospective businessmen will not fall into his cheap trap.

Thanks for the heads up

globalfanz:
Safeplux so you are still alive. You are not picking my calls and all promises you made on Whatsapp for the completion of the procurement I gave you for over 5months now is yet to be fulfilled. How can you take up business and disappear? Kindly provide my remaining goods or you balance me. I advise any serious individual not to deal with this dubious guy. At a point he disappeared and was claiming health challenges. My business with him is yet to be completed. Goods woth more than N100,000 is yet to be supplied for the past 5 months.

I don't like businessmen that mix personal issues with business. Even if you are on life support, a business deal should still continue. Nairaland should have a way of verifying people in the business section. One can't just be spending money on scam artists masquerading as businessmen

Samuelscott:
Guy pls what dose this mean

Your item has arrived your local post office. You'll need to go there to pick it.

Peterlove11:
Thanks......My installer installed only Surge Protection but no Circuit Breaker. Am bothered about it. Can someone show me a pix of a CB in a solar installation. Is it possible for a lay man to install it on my own, and if possible how can it be done

See line diagram and see if it's something you can do

Peterlove11:
Please what is the difference between a circuit breaker and a surge protective device.....which is more important in a solar installation?

Circuit breaker opens a circuit (connection) in the event of fault, overload or abnormalities in the circuit. The surge protective device as the name implies protects the circuit against surge from the system (lightning, or just a heavy equipment start or shut down). The two are VERY IMPORTANT in a system.

Ordered 5th May...picked from PO on 9th June

Shipping of some items has improved.
