Expectedly

dollarnaira:


And the wooden case will be cheaper while direct cells will be the cheapest. All na same na just aesthetic. Variety they say.........every man with im choice.

Thanks for the compliment.
Against wood degrading pests, the wooden casings stand no chance.
From this month however, 12v 3.5kwh/4kwh buyers wll have the option to choose btw plastic and wooden case. 24v 7.1 - 8kwh buyers will also have the option to choose btw wooden and foreign metal case.

jmaine:


Hello Mrreed, thanks for the alternate offers you render for your lithium packs.
However, I did like to know how durable your wood casing is in areas infested with termites, or other wood degrading pest agents known to be very destructive?

You will also say that manual transmissions are better.

ask4bk:
We Nigerians praising inverters like Growatt, SRNE etc which are cheap and high frequency shows our shallowness in good solar applications..

Growatt in the west is meant for the poor who can't afford solid inverters and for 80% s they die on them after 18 months or 2 years.

Manufacturers of inverters make it clear to s not to use high frequency inverters for heavy loads. They are not meant for devices with inductive loads like fridge, freezer, pumps, AC. They are not meant for offgrid home applications when you know you'll use the loads. High frequency inverters (without transformers) are for light equipments like lightings, TV, phones, laptop, security cams etc. That's why they are Damn cheaper than low frequency ones. There components are not meant to handle heat for long.

But for us, we will use them with AC, pump, freezer etc and since it's working (of course it'll work), we claim they are the best. But they won't last on the long run.

A low frequency felicity inverter is multiple times better than your highest brand (Deye, Growatt, Tesla) high frequency inverter for offgrid use with heavy loads.

If you are going for offgrid, spend the extra money and get yourself a low frequency transformer based inverter. They are made to withstand heat, dust, heavy loads and harsh environments.

If you need inverter for your office, farm or home, for just light, laptop, TV, printer etc. No need to go for low frequency. Go then for high frequency inverters and save cost

The same way there are not many 24v 5kva inverter. Anyone with a need for such battery capacity will be better off using a 48v system. You will save on cable and won't be stressing your inverter and battery unnecessarily.

HeavenlyBang:


Damn, I don't think anyone else is making 24v in these capacities.

Gotion 314 98k (few units left)
Eve 150ah 57k (should be available from nextweek)

Gshems:
Mr Reed how much be your cells

With a continuous power draw of 280w, 7 hours at best. You have to for the inverter power consumption and its DC to Ac efficiency.

Fremlin:


These batteries are with BMS and Also LiPO4? getting the 25.6v, 100ah, with 1.5kva, will it handle
120w freezer
60w laptop
100w miscellaneous

For 10hrs?

might be using grid, no need for now

Didn't see the budget cap before responding. 2m should get him a battery, inverter and 5 s

Dam5reey1:


7.1KWH wont be bad too, cause his 2M budget will be exhausted already

OR
620w from Fouani x6 <125k each
(the key to getting this price is if you have of electronics seller that buy other things from Fouani. You can liase with them to help you order this straight from company)

6kva Luxsun/cworth hybrid inverter circa 450k

The other materials will cost 160-200k if the s will be on your roof and yiu stay in a bungalow.

If you don't mind DIY Battery, I can make 14.3kwh battery for you for 1. 650m

Workmanship, look for a competent person around you or hire from here.

Stormyweather:

Someone gave me this bill.

What do you think?

Your perceptions are usually weird.
So because some batches probably have factory defect, that makes them comparable to tokunbo or used with up to 50-50 chances?

bassdow:
Major reason I try as much as possible to avoid going for repairs. I recall when I said something against sachet inverters, and some One / people argued that the parts are readily available and could easily be fixed. Me just dey look dem. People wey don go through stress of finding technician, then they charge you high, still give you time to collect which by the Day and Time you go for collection, you're told one story or the other; and you fit go there like multiple times before frustration go take over. No one tells you such, but all sweet talk till you experience it.

By the time you add cost of transportation, cost of repairs (depending on how many times you repair it), + other stress, and costs, no be to kukuma buy better product even if na Tokunbo or 2nd Hand.

rarely do I even listen to all the Warrantes and Guarantees.


Major reason the moment I know a couple of (average) quality ones, I stick with them. Client wey complain of costs, or chooses to shop for themselves, me no go even argue, I go just bill you for installation; unlike those wey go dey vex say you go buy your things yourself.

Of course

CuteMaro:

Can the bms be swapped for a smart one? Is it possible?

The only con, they should have substituted that for a smart BMS.

HeavenlyBang:


This Haisic doesn't have a display at all fa? How would you check cell voltages on it?

When you search his moniker, you will see why he shouldn't be taken seriously.

ManAdii:


I see two things here. It's either your mind is made up already and you're just looking for a validation to get either of the batteries or you're not getting what the people above are saying.

How can you buy 48v 100ah for 1.8m where you can get a good 48v 280ah or 314ah between 1.9m ~ 2.5m. It doesn't make financial sense to me.

Anyway, your money, your decision.

You say?

ManAdii:

I observed that this Haisic no get 24v batteries

This chart should be helpful

fuckboys:
what about a 4mm solar cable on a 4 420w cworth s on 2pS2p Connections on 12v system.

That's 2parallel series 2parallel

4bmm is fine. The maximum current from that PV will barely excede 13a. Between the charge controller and battery is where he will need 16mm cable

oloet:
For science, I think you have actually created another problem by using a 4mm cable in a 12v system, that's like 58A running through your cable line at peak hours since you are over led. Please make sure your breaker is properly sized. Enjoy your investment

86-90% of rated capacity.
Considering it's price, it's a good deal
Brand new 12v 280ah pack will perform better than this though.

Dam5reey1:
Final results coming to YouTube and TikTok..

Abi make we just conclude..

Just like your twin here, it is almost impossible for you to write without being condescending or throwing unnecessary jabs

bassdow:
You mistaken. If only you could calm down and use the internet intelligently, you would confirm what I say.

Anyway sha, I am neither here to show Off, or act ITK.

The thread is mostly for adverts, sprinkled with a few DIY like talks hence no need me stressing ma sef.

Something wey even technician fit help you convert / add sef.

Me don close mouth for this topic abeg

You can use the alibaba link below to the supplier.
He sold it for 140USD. May be you can even get a better offer
https://x.alibaba.com/AzQAwD?ck=minisite

saint2ace:


Link to this please

There are inverters with dual voltages but the tech is still not mainstream.

AndroBlaze:


Please share examples as I've also been looking for this kind of inverter for years.

To make it clear, what I am seeing from your posts suggests that their are inverters that can different voltages of batteries at the same time i.e. 12v battery and 24v battery ed by the same inverter?

You are trying to understand individuals with obvious agenda.

HeavenlyBang:


Instead of doing "you can", how about you actually say how it can be done.

Na person carry the Deriy batteries come here, since then e just be like say e dey vex some people.

If you have an update on how to make solar cheaper for people, then share and quit meaningless tirades. I no dey understand this thread sometimes.

Which one are we even producing among the Renewable Energy components?
Cells? BMS, CC, s?
Local fabricators can't even make decent casings for battery pack.

dollarnaira:
Gradually we are marketing products we don't produce. Giving free adverts to companies that don't even know us personally.

They are like football club fans that know all about players lives but refused to be known. Real fans are at the stadium watching life matches.

No carry people product for head like gala. There are several products working better than popular ones.

The voltage of the configuration does not matter as long as yo uare within the voltage range of the CC. Don't get it mixed up

bbally:


Bro, don't play dangerous game with your cc. Things are costly this days. Most 12v configuration should not even 70v to give room for open circuit voltage rise.
Study your gadgets specs very before any connections.
My 2kobo sense

He is either lying or he doesn't have enough info about the battery pack. I once posted the spec sheet here, the recommended charge current for Haisic is less than 0.15c. That should tell you all you need to know

Dabss:
https://vm.tiktok.com/ZMBG7eeVU/

Guys i found these guys on TikTok. They claim their batteries are grade A and their prices are very good.

I only quoted 70,actual price is less than that.
0813. 119. 9386.

Trippledots:


This is exactly the route I'm taking and it's very cost effective. Abeg where you see that BMS for $70, because Kayla is giving me for over $100 o. Drop your Whatsapp let's talk if you don't mind.

Dami did capacity test but he faced many resistance when he posted the result here and on the telegram group.

Waiting time is the only disadvantage for Deriy packs and some have also been lucky to get it under a month.


From all the major suppliers, brand new hithium 314ah with 1c ratings currently cost 39-40USD,shippong to GuangZhou additional 20USD.
Even eve 280k v3 cost is around 40USD/cell
The cost of shipping 16 cells to Lagos <= 200k
200A terminal <= 16k
Jk200a BMS with 2a <= 70USD
4. inches display 20USD
3.2 Inches 9USD


Without casing, the total cost is circa 1.5m.

You see, even Deriy makes reasonable profit for selling in that range.

CuteMaro:

I think he is talking about it from a 'Better deal' perspective factoring in the price difference, wait time and uncertainties around logistics (according to his opinion).

I tried to search for Valto's packs capacity testing or tear down but so far there is none.

You probably have something against Deriy. Deriy makes pack with most of the popular cells and they are all brand new. Many have been able to pull full capacity from it too (3.5v - 3.0v).
As for Hithium cells, they are specifically built for Ess and they also quote longer life cycle for their cells.

clevermugu:
investing 1.8m or 1.9m for a Hithuim 48v pack to a Chinese in far away China and waiting for 3months,doesn't make any sense. what if there is serious shipping delays or something happens
getting Valto's Eve 48v pack for 2.2m within 24hrs of payment is far far better.

10-12kva inverter x2 in parallel
20kwp facing the south
30kwh battery.

I think It is also better to switch on the pumps one after the other too.

Emmalex83:


Thanks Boss. They have all this things in place is just something that will help them reduce the Nepa Bill.
What i needed is a breakdown of numbers of Solar s, Battery capacity and Inverter capacity that can power the 12HP pumping Machine. Mostly during the day. Thanks in anticipation

I honestly can't

Drgreatone:

What VOC were u getting with the initial 4 s? I usually try to get around 150v and it works well for me

I have seen it many times. Sako 5.5kva, I used Jinko 450w x4 and the yield was below 10% till I added 2 more s.

HeavenlyBang:


That wouldn't limit his output to 500w, though. Don't think I've seen an MPPT that requires higher than 120v startup, which his s supply.

If the cc in that inverter is >=100a, the problem is insufficient voltage. You need to add more s to move closer to the mppt range

lagbaja:
Guys, I installed 3 units of 48v ( Max) 600watts Africell solar s connected in series on a 3.5KVA Wellion Hybrid inverter. The display on the inverter shows an open circuit voltage of 132V and the highest power output I have gotten is 500watts even when the sun is brightest. What could be wrong ?

It's in the market and some sellers list it here too. DYOR before picking a brand

cutefy:



Okay thanks for ur response.
How can I 80A. The only size I see around here is 60A..
