well the one I got has grade A cells, smart BMS with communication. Nothing you say about Deriy will justify 1M for a used 7.5kwh battery bank. At least to me.. 😅

There's a basic question I've been expecting to read regarding this BUT unfortunately, no one has bothered to at least compare price of brand new vs USEd 7.5kwh deriy lithium battery.

Mind you, no be me advertise battery so abeg pity ma head

I got a brand new 8kwh (Black) Deriy battery for 1.250m a few weeks ago.

Now this is what I expected most of us to do. Compare Oranges to Oranges or Apples to Apples.

Now with enough evidence, Advertiser might need show how they came up with said price for USEd item.

Don't wanna hear read price was negotiable Ooo

I see. Someone like me have no need for communication sha 😂. Just give me true capacity with a sturdy case and a bluetooth supported bms to monitor cells, and I'm good.

That makes the two of us. The most I want to see is how individual cells are doing in my pack. So a smart BMS it is. And that's the only thing I have in my self-built pack of over 5 years.

Careful before you're called oldSchool. Some believe all those bling bling features are a necessity

I opened my haisic 4kw 12v battery today. I for like change the bms in it. I can't monitor the cells. Anyways Who get shunt for sell

I think comms are important. For instance, my bms app no dey gree work again, so I change settings via comm cables and rs485 dongle.
I have reinstalled the app severally, checked several jk bms app versions, nothing dey still work.
Having the comms is an important option IMO for DIY people.

Comms is useful when you need it and know how to use it and use good enough inverter. Some people's inverters are so shitty paying for such feature becomes a waste of funds.

But then again, some people's inverters misbehaves when no comms.. Yea you might say use USER defined settings but that doesn't always help for some shitty inverters.

well I travel a lot so I don't joke with remote monitoring. I like to see and know everything down to the bulbs and switches.

This is a use case I will consider and implement soon as I may be spending prolonged time away from home.

Monitoring cells is important o. They get unbalanced over time and may need top balancing every six months. Some lfp cells that 'lose' capacity within 2-3 years, na one crazy cell they cause am. Checking cell behavior at regular intervals helps to maintain the life span.
For me, monitoring is why I first realized that I bought fake panels in the first place and galvanized my solar journey.

good morning,please ia their a special device I can get to properly balance the cells in my battery? Charging with my lifepo4 charger alone doesn't fix the imbalance . My BMS is passive

e good as una don dey Gradually list out some of the quirks and cons that comes with Lithium based batteries.

Shey na me go dey monitor batteries like we monitoring blood pressure of a diabetic person.

When I make certain comments why I personally don't and wouldn't use Lithium batteries anytime soon, some go call me oldSchool just because I refused to blindly follow the crowd.

As for clients, I just give them options, explain to them and let them make the choice.

Me wey dey rarely see ma batteries for long. Things continues working like it's natural 24-hour light.

yea leadAcid batteries got their own quirks but so is everything in this life. Even to serve God get e own CONs.

Monitoring cells is basically just opening your bms app and checking it which takes a few seconds. Infact you almost never have to do this unless you suspect a cell got bad.

This is rather an advantage over Lead Acid my brother because it means you can troubleshoot down to specific cells and replace if need be. No need for guess works and you don't need special tools.

The superiority of Lithium over Lead Acid is just way too much, you can't compare.

You really need not tutor me on how to handle lithium batteires as even if I don't persoanlly use them on large scale, the nature of my work means I interacts with them regularly.

And have never said Lithium based batteries ain't superior. Just that like everything in life, there's always a good and negative side hence why one needs know what suits their specific unique needs.

And yea, there are things I wish were possible with leadAcid batteires but then, we really can't have it all. Lithium based batteires have lots of moving parts compared to leadAcid based batteries and for those of us who love to set and forget; it means a lot.

That doesn't mean I don't have pet projects using lithium batteires BUT none is above 50AH.

Of course using leadAcid batteires in large scale means you got a room looking like a battery charger's shop because of the huge space those monsters occupy BUT with vertical stacking, things are much neater.

If I ever have a reason to replace those leadAcid batteries with Lithium batteries, I would be ready (financially + mentally) to spend huge and that's something I'm not ready for anytime soon. My Youth is for building, not spending abeg.

Imagine cost of replacing entire 24pcs of 12v 200AH batteries which have been diligently serving for years just to be up2Date. Last year, I did some maintainance where I replaced 4pcs out of them.

And Guess what, whenEver I got access to batteries I love, I could just do spot replacements within minutes. Such freedom alone is pure bliss to ma wallet.

So yea, Personally, I wouldn't be using Lithium based batteries anytime soon. Don't have such pocket yet + other reasons.

BUT then again, it's so because I know my exact specific requirements and capability.

Thanks

What do you guys think of this explosion: https://www.nairaland.com/8699171/smoking-solar-battery-explodes-after

The battery looks like a cheaply made local battery.

Don't worry. We don't think anything SIR. ANy battery could be in similar situation irrespective of it's cost.
No one is asking what said battery might have been subjected to.

Enjoy brother. People like us are on the lookout for newer higher energy density technology. We need people like you for reference purposes. 😂

Ojigbi jigbi

My head o

The battery backs must be outdoor sha. Or in shed because I can't imagine all that indoors

And I don't think there would be much tubular batteries in the mix cos the cost of constantly re-filling distilled water and electrolyte..

So it brings us to the type of SMF battery you use... Are they mostly AGM, GEL or VRLA

Thanks for anticipated response

bassdow:
Shey na me go dey monitor batteries like we monitoring blood pressure of a diabetic person.

Just a lil correction, diabetics don't monitor blood pressure what they monitor is blood glucose/sugar level.

Well done.

So indirectly you call me a Museum.

No worry, so long you can comfortably afford + maintain them, no issue BUT me dey do according to ma power. It's easy to quote figures for clients BUT when e reach to do ours, we go begin match break due to costs. It's cheaper for me maintaining and running such capacity of leadAcid batteries compared to Lithium based batteries.

To the one who asked the battery type. Used to be dryCell but have replaced them all with Tubullar batteries. As for the reFilling, I built some sort of system to automate such where I use that thing that stops water from overFlowing in toilets. of course had to do some modification to make it smaller and used them per battery. Hence I only have a single central place I store distiled water.

As for the distilled water, rarely do I spend on those as I already have a system I use in doing that. I have a modified pot with hose that goes into a Gallon so when I booil water in that kettle using fireWood, the steam passes through the hose and condenses into water inside the gallon. It's similar to the water that drips off your AirConditioner.

And yea, a DC standing fan is dedicated to them.

Your solar system setup should serve you but please note my advice below for consideration:

1. Change those LCD TVs to LED
2. Ensure only DC fans used. I recommend yohako ceiling fans. I use two in my game house.
3. Lastly, your focus should be the battery because the more capacity you are able to derive from your battery system, the more hours of extended electricity you get to enjoy.

I also run a game house, you can buzz me on 09031988862 for further discussion.

jFrankNorfleet:
House I need your help with information needed so I do not make mistakes a novice, that I am, would make. I want to install a solar electrical system for my game shop and I would like to hear what you'd recommend for this setup

Here are the contents of the shop. Note that the wattages I put there are all gotten from looking at the back stickers of each TV

Lg LCD 32 inches TV 140w *2
Samsung 32 inches led 56 watts *2
Samsung 32 inches lcd TV 110 watts *2
Samsung 15 inches lcd TV 40 Watts *4
PS2 fat 3pcs
PS3 super slim
PS3 slim 4 pcs
PS4 slim 2 pcs
Ps5 1 pc

There is an ox industrial 26 inches that I use right now and a plastic fan of 60w. I plan to get rid of both fans and get both DC ceiling fans and DC standing/wall fan so recommendations are welcome pls

All games do not operate at the same time, out of a total of 6 PS3, 2 PS4 and 1 ps5 only 6 can be operational simultaneously, although I plan to add one more 32 inches tV as time goes on which would eventually make the operational games seven in number

The gamehouse typically operates from 9am till around 11pm.


I called an installer to tell me what I'd need to do the installation for the shop and here's what he recommended I do for the setup



SYSTEM REQUIREMENTS
Growatts 6kva solar inverter

Growatts battery (5.5 kW/h x2)

Jinko solar photovoltaic panels(615 watts)

ACCESSORIES AND OTHERS
1 DC SURGE (500)
1 DC BREAKER (32amps)
1 AC SURGE (500)
2 AC BREAKER (63amps)x2
1 DC BREAKER (63amps)
OTHERS:
18 way breaker box
4 way breaker box
Knife switch change over
Trunking pipe(50x50)x3
Photovoltaic panels rails(x3)
