How did you DIY that? Did you have to use a potentiometer?.

Yeah, but factory built into the pack

Even at 30% DoD your average LA will do under 2,000cycles. It is still not very close to Lithium.

I was only trying to dissuade the notion of 200Ah Lead Acid = 100Ah Lithium.

You will always need to upsize your Lithium bank for a realistic DoD and the proverbial rainy day.

If someone can squeeze 180Ah from his 200Ah LA bank a few times a year because not enough solar harvest or no PHCN or Gen, it would be lights out for the Lithium 100Ah guy.

In practice 200Ah LA will need about 130 to 150Ah Lithium as equivalent.

If your point is just to talk about taking out power from the batteries then 200Ah LA is equal to at least 160AH LFP.

However those who said 200Ah LA is equal to 100ah LFP were saying that on the basis of getting reasonable lifespan from the LA.

No matter the quality of the LA if you consistently take over 50% out of it, it will half it's life cycle at the minimum. Lithium will take that without a loss in life span

Since the loads are not sensitive, you can make do with a modified sine wave inverter

1000/500W inverter with charger - good for days of bad weather, charge with the grid

2x 150W panels

30A solar charge controller

100Ah L.A Battery

Other accessories you choose to go with it, depending on your knowledge of how it goes.

Note: you can buy all accessories yourself and call a local Installer to do the job for you

Jiji is a good place to start or you can reach out if stuck

Oh I would really appreciate if you can help me out. The number on my signature is on WhatsApp or you drop yours let me reach out. Thanks a lot already.

I'm looking to buy this ABS toolbox empty case for my power wall lithium DIY...anyone know where I can get one locally in Nigeria with the following internal dimension 305mm* 280mm*178mm?

Are you planning on LFPs or 18650s? If it's 18650s power wall, you may use something that is more widely and easily available locally - the adaptable boxes - and the biggest size will allow about 14s, 12p of 18650 cells in the minimum. For handles, inexpensive handles like those type used on power stabilzers are available for purchase on AE and quite easy to fix.

These ones are 48v 30 ah each, to be stacked in about 10 units one on the other.

The packs per box are pieced together in 2 units of 7s12p per box meaning it can be adapted to 24v by a few reconnection and replacing the BMS with a 24v.

omotoda:


I have solar. 4 units of Felicity 260 watts panel hooked with 60amp PowMr CC

Fire on then. Keep your luminous inverter and acquire your lithium. 4pcs 260 Watts panel is a very good start.

NiyiOmoIyunade:
When Lithium is done right you literally have zero fear. When a Lithium customer calls you, you know it is for a battery or inverter or solar upgrade if na lead acid, your heart starts to beat fast when you see your customer calls within year one

I can identify. Even for me that did a number of installs pro bono, that fear of calls no be here. One can suddenly develop throbbing headaches at that instant. And you gats go, if you have a reputation to protect. Good that lithium came to the rescue.

omotoda:



I better start putting up my Luminous inverter for sale.The only reason I haven't gone Lithium is because of my inverters. The price sure makes sense when you compare it with Lead Acid batteries that will give you just 50% DOD.Full river battery as at my last check with the sole importer in Nigeria about 3 weeks ago was #155k for 200ah.So technically ,Lithium is better cost wise in the long run.

I have a 12v 1.5 kva Icellpower inverter with adjustable settings lying fallow in my store.Does anyone know if this inverter can work with Lithium? If not what affordable and durable options are available?

Ur icellpower inverter is perfect as it has adjustable parameters for charging including adjustable DoD; the low self consumption also makes it a good choice...... So no need getting a new inverter unless charging speed is an issue, then all u need do is add an external charger like the one @valto and @ojeysky have and u're good to go........

It's wood, so u can play around with what u want, just but a 200naira handle and screw it in and u're good to go, u can even attach wheels if u so desire......

It powers a small bedside fridge so well it's just battery that is the problem.

Then go for lithium, will serve you well

The empty container... was interested to use for a tool box...

There are a number of vendors on this thread that will provide you with various prices and different products. You can then decide on the products and prices of your choice via a vis your pocket.

Not sure, but I think 150 Watts is around 28k apiece. You can go for 170 Watts or 180 Watts since it appears the cost is the same.

Nah, I bought a 3.2v 22AH Lifepo4. I've considered this, but I doubt it can handle the battery size.

Mine is 100amp LifePo4.
It fits comfortably in a wooden box made by me. If u decide to give it to a professional, u wud b surprised at what he wud design for you. Just make sure u put holes to allow for ventilation. How many pieces are yours?

Ranges between 30k to 26k depending on the brand of the solar panels

I agree with you. The mainstream is now gradually and faster than ever drifting towards lithium. The affordability is easing and with many offerings and start ups in the market (save ones like felicity that lie about capacity), it can only get better.

I think to my guys that still stick with Lead acid, it is a function of what still works for them, the ability to have a hugely oversized bank (as is expected to be with lead acid) that does not impair functionality much and probably in addition, the undesire to give up on a huge investment in LA in favour of lithium without first maxing/squeezing out the last drop of the investment on it (lead acid).

I believe acceptance and transition to LFP despite being an avid fan of LA was easier for Oga Níyì because he had clients that were much more interested in the new thing, he had to get them their choice and in the process had first hand exposure to LFP. The need to properly intimate himself to that chemistry in order to serve that section of clients necessitated owning banks himself. And now he is a faithful disciple. . Now he apparently even wants to do away with just few weeks old 272ah cells in order to upgrade to maybe 1000ah cells. Ha! Baba, Tuale o.
I hope I assumed correctly sha.

In the coming months, we should see guys engaging in e-vehicle constructions or modifications, starting majorly with e-bikes. Maybe this thread will also accommodate that new entry or perhaps it will have its own thread altogether.

i couldn't have said it better. and for someone not trying to offload any solar wares to prospective clients, that
says a lot.
and like someone said in a previous message we been through all this lithium vs lead thingy a while back so i'm
not really going to do a repeat. lithium is still evolving and going mainstream by the day and for a long time to
come will be just another option besides lead acid. let us take that into account as we dissect info on this thread
so that newbies planning to take the renewables route would not necessarily get the idea that one option is evil
and to be avoided at all cost while the other option is good and to be embraced regardless of the cost.
balance of info is key here to avoid peeps being led astray.

Errrrm
You err kind sire

Was on your side of the table 2 or 3 yrs ago when this issue was discussed, i know better now

A 12v 280ah lifepo4 can easily and safely power a 1.5hp ac without issues , but to dream of powering same load safely with leadacid, you need minimum of 8 units 12v 200ah cells. ...........

Why you are enjoying your lead acids is that you are frightenly oversized, with those your 2v 2000ah. Its akin to 3.2v 280ah in terms of load you can put on it, but cheaper and lighter in weight.

A 3.2v 280ah lifepo is about 5.4kg, while a 2v 2000ah would be about 150kg......

bro, its a bit gratifying to know you were on my side 2 or 3 years ago but i really don't think its about taking sides.
and if we should really take sides i think we should always be on the winning side. and, for me the winning side will
be the side that works/performs without stress.
i don't know what formula you used to derive your calculation which makes 2v 2000ah equal to 3.2v 280ah but i can
assure you there's nothing frightening about the size of my battery bank. a lot of effort was put into arriving at a
right size bank for my household needs and when the opportunity came knocking i gave it all i could muster and like
they say, the rest is history.
not everyone has the constraints of space and not everyone bothers about weight so what might be a show stopper
for you might just be a walk in the park for another person.
like i said before, lets leave all the options open and keep a balanced thread. lead acid will be with us for a long time
to come even as lithium continues to gain acceptance.

I agree with a lot of these. There is a sure market for lead acid batteries now and in the years to come. Lead acid is the staple, common item that everyone knows and are familiar with especially for smaller systems.

For a RE first timer, it is probably best to start off with lead acid before going the Lithium route especially if the plan is to DIY or self assemble your cells. If you are getting a professionally assembled Lithium pack then that is another matter entirely and I heartily recommend this to anyone who can afford it.

Let us not forget that some Lithium ion chemistries can be explosion and fire prone if abused - luckily most of the builds I see on this forum are the more stable LFP and LTO chemistries.

Before LifePo4 wud result in fire, it means it has bn overly and extremely abused. At 45 to 60 degrees.
