You are here busy advertising.....
Why did you have to send 1kVa instead of 1.2kva inverter as agreed upon? You will have to explain to me cos I was the one that gave a friend your number to buy from you and in the process I had to order through him and you sent a lower spec.

Yeah I did send him the 1kva cos that was the one I had in my shop. I already explained everything to him, and also pleaded with him not to be angry.... No vex boss!

my little word of advise is that do not go down this route your word should be your bond and if you do not have what was agreed you must let the buyer know so that he can make his own decision on the lower spec. Na so one complaint becomes 2 and so on until your integrity will be put to question. Tread carefully alot of people get feedback on this platform and you should ensure that the feedback is positive a word is enough for the wise

Boss why are you throwing shade na?

Despite having installed several Victrons, my respect for them grew only after I began to use them on the daily in my own house. The solar charger is certainly not better than the MorningStar but the ease of configuration, upgrades and user interactivity is second to none. They beat MorningStar and any other product I know hands down in the software and customizations arena.

They are also virtually break proof even in the hands of a noob or the face of a mistake - I have broken two MorningStars in my career, never yet broken a Victron.

But if you want a CC you can use on the NorthPole or Sahara desert and come back in 10 years to find it still working like day one - go for MorningStar.

bigrovar:




Even expensive ones .. don't want to name names (but it rhymes with Morningstar) many of the expensive tier 1 controllers would blow up when you disconnect the battery while actively connected to the solar panel. The key is how victron cc where designed. They were initially designed to have their internal circuitry charged by solar if solar is active and battery if solar is not available. This makes it to easily survive a battery disconnect.. I always Yimmu at @Niyi when he goes on and on about morningstar.. I can say right now that Victron Energy make the best controller in the market .. in terms of performance, ruggedness and integration with IT.

Same here. Na the money wey man pikin suppose take buy car enter inside PylonTech battery but no regrets whatsoever.

It works in a way that lead acid just cannot - if you couple it with an active controller like the Venus GX device, your smart LFP will talk to your inverter and CCs and tell them exactly how it wants to be treated per time. Certainly a match made in heaven.

You have to use/own a good quality LFP bank to understand what I am talking about.

mctfopt:



Too late to wait. I'm enjoying LFP already and I doubt I'll ever go back to lead acid

I love watching 100A flow into em banks and get it floating before 2 hours. Even if it fails tomorrow, it's been nice rocking it.

This is where the PylonTechs trump any cheap Lithium or LFP offering.

The inbuilt BMS is a texas instruments BQ series with texas instruments balancers as well. The BMS can also control a chargeFET and dischargeFET to prevent overcharging apart from it being able to balance the cells.

Couple all this with the ability to talk to the inverter or CC and communicate precise charge voltage limit, charge current limit e.t.c That is why the PylonTech will surely do 10 years plus.

I have had my bank 4 months or so now, daily discharge to 80% and not one thing is out of kilter. Everything works buttery smooth and I can monitor it all from either RaspBerry or PC.

A set of solid LFP cells plus a top quality BMS with comms ability make for a wonderful battery.

ojeysky:


It's just 4 months usage and mine was a packaged DIY, I recently noticed it's a little unbalanced and the Daly BMS is not doing a good balancing job so I will either have to do it the manual way, semi manual or wait till when my ANT BMS with an active balancer arrives. No thanks to covid-19 at the moment.

To your question, my response is based on my study and what I will be doing if I have new cells (I am also trying to increase my capacity, I have 4 cells already waiting for the rest), when they arrive I will bottom balance by making sure the voltage is almost the same (with max of 0.02 diff), I will then parallel all the cells together and leave it for a day to allow for proper voltage level and capacity sync. If that is properly done with a proper BMS installed then you won't need balance for several months to come (with all things been equal) as the BMS will handle little lags.

The above is what I call the manual way, the semi-manual involves identifying the cells that is moving faster than his team and adding sufficient drain to the cell once it's passes 3.4 so that the rest of the cells can meet up with its voltage level while charging which is top balancing

That said, what's the specs of your cells? As they seem long and wider than the normal prismatic cells

Noted boss, thanks.

bigrovar:


Which is true but still very very expensive, an expensive experiment which often time ends up in failure.. You know why? Lithium is very very complicated and has many component all of which have to work just right. Lithium has very little margin of error in setup.. You have to get the right cell from the right cell maker, you have to ensure the cells are well balanced, you have to get the right BMS, right charger sometimes the right inverter.. One mistake and poof all goes up in smoke.. and they often do more often than not you just don't hear that part in the songs

Many on here have dipped their hands in lithium and gotten burned badly and suffer their loses in silence.. You will hear them throwing specs like 3000 cycles at 80% dod lol.. what u don't here is the case where the bank (if you are lucky) just stop working after like a year.. They just stop..

Lithium is the future no doubt.. Just waiting for the dust to settle.. maybe when reputable chinese solar maker like episolar start doing lithium then you can take a cue that it is time to give it a look. for now I will advise wait for the second iteration before you look that way

But it's funny the way you alleged that majority of lithium users here have gotten burned badly but suffer their losses in silence. This is largely untrue. The majority of failed lithium setups that users have posted here, myself included are DIY 18/65/0 cells the limitations and dangers we all understand before even going into DIY assemble with it. In fact, I still posted pictures on here a failed DIY 18/65/0 pack that went south few weeks ago. The failure was not unexpected, but I learnt one or two lessons and would not make the mistakes going forward. Those are the things expected of DIYs.

But I stand bold here and say that I have factory packaged lithium packs that is still going strong for me 4 years. Some I purchased new, some have been used for more than 5 years before I got them and they are still as strong as the first day I got them.

My recent acquisitions in lithium changed from 18/65/0s to LFP which is a safer, more mature concept than the tubular 18/6/50. I have been using this for 6 months and I make bold to say that I have not have headaches using it as I had with your lovely lead based batteries. In fact, I actually gave out for free all my lead batteries which were replaced by lithium. I just gave out a 100ah this afternoon.

Believe it or not, I still plan to keep acquiring more LFPs as my purse allows. Ojeysky is another avid LFP user that has good testimonies.

The pylontech you used as your yardstick for your poor rating of LFP is another class on its own and a breed that requires use with similar products designed to be connected to it, so you can't blame people that have acquired reasonably priced and equally good Chinese alternatives that does not require the stringent conditions pylontech requires for seamless function.

Have you read about CATL prismatic LFPs? CATL is the Chinese company that Tesla have partnered with to provide them lithium for their new line of electric vehicles. This is because CATL prismatic LFPs are cheaper to manufacture than 18/65/0s and are a lot safer. BMW uses CATL cells in their e-volt lineup.

My most recent factory LFP pack acquisition are the same CATL cells straight from the same manufacturer that supplies Tesla. So bro, forget that thing. All you said up there about LFP does not hold much strenght o.

Thank you jare bro. You sabi wetin dey. I know the feeling about changing what one totally believie in to a novel and better option. It's not easy to accept that change and one would tell experiences and believe everything that tends to disparage the change. That is the phase bigrover is currently in.

I'll be hanging around the corner to gloat and mock him the moment he goes lithium, even if it takes the 4 years timeline he has promised. God spare us all.

In fact as I dey now, I just wish I have enough cheddars to order than Felicity lithium Manuel just advertised for bigrover, just to give him a tiny taste of the delicacy. Hearing him swallow his words will be priceless .

The right combination makes LFP the dream.

essegis:


Even for top balancing I will still have to parallel them. Only difference will be a charge would be applied to them as against discharge when it's bottom balancing.

As for the cells they are rated at 66AH, 500WH. But these cells are not new and they being used initially in an electric car one does not know the condition they are coming with. Though seller sold at 65% capacity and a lot of folks have been getting that or higher.

I don't know what you mean by significant storage as they are not brand new. I ended up buying 57 modules though at an overall price of just above $2000 (a full pack containing 48 modules then 9 extra).....the shipping cost a arm and a leg sha oo. Planning to set them up in 14s for a 48v system and yes I won't have to go digging too much before I can get inverters that will work within the sweet spot voltages of this system. They are compatible with most inverters out there.

Wawu.

That's an impressive acquisition you got there. E no easy. Wehdon sah

ojeysky:


Post offices in my state was on lock and key until this week that they are opening 3 times a week, having not yet received a call planning to check on them by next week.

Has tracking of the item been updated since it arrived Nigeria? If not, then don't expect it in your local post office until 2 weeks after tracking in Lagos is updated.

All items I ordered only got tracked till it got to Nigeria, likely the port. The customs will still have to do their thing before the post office people distribute it from Lagos to other states. That usually takes like 10 days in times without Corona.

I once get a seller that claimed he supplies Tesla batteries

But the truth is Tesla sources his battery from China. Even the so-called Fortune cell LFP batteries are all sourced in China and better packaged and sold at a higher price than similar batteries in China. For now, Chinese are doing well in the LFP industry. The cool thing is if you know how to source, the difference between it and lead acid battery is not that much in terms of price. But in terms of performance, they are a world apart. Truth is I regretted all the lead acid experience, poor charging, occupies more space, and generally dies before you could recover from your expenses, etc in my opinion. Anyways, lithium is the energy storage of the future, guess it'll keep getting safer, and of course cheaper, as the technology advances. But this is my goodbye to lead acid, it has been fun while it lasted.

It is true I'm holding my breath with my lithium bank, but I like what I have seen so far. Faster charging, reliable voltage, small form factor, ability to spend all the money you spent on buying the battery when needed, rather than a small fraction of it. I very much doubt I will ever go back to lead acid. I'm even looking for Lithium for my car and jump start. Once the corona things levels off and I can get some small coin from my lenders, I will buy a little more to get rid of my remaining lead acid bank.

bigrovar:

Yeah, so can AGM.. I am still 4 years away from getting LFP. I am still not sold on it yet. The tech is still too bleeding edge and expensive for now.. a 140AH pylon setup would cost close to 1.4m (at N360/$) If I spend N500k on 4 Quanta batteries I would get 400A which would serve me for 4 years of diligent use.. I can then turn the 900k to dollars and put it in a eurobond account for the life time of the Quanta (4 years) by 2024.. my dollar investment would of grown.. Lithium batteries would have gotten better and cheaper and I might still be able to buy the cheaper more efficient and more capacity lithium from the eurobond investment. Economics of Lithium doesn't work for me .. yet.

I'm interested in this eurobond talk sir. Can you enlighten me more? Probably via whatsapp so we don't derail this thread.

I certainly have no doubt that pylontech users would have reasons to justify the pay. I am also not surprised that pylon may do up to 10 years, as any other good LFP can also achieve same, if similar charge/discharge rate applied on pylon is applied. Let's not forget that pylontech itself is Chinese and infact China is the most advanced with lithium technology so infact the lithium cells I am using in my DIY may actually be of same quality with the one coupled in a pylon.

For battery management, with an ANT BMS coupled with an active balancer, I get the ability to monitor and manage individual cells. The only thing that will be missing is Comms with inverter/charger which IMO is not important if the systems are properly setup.

Overall we have our individual preferences but if I have a pylon budget, I will certainly expend it on a good DIY thereby having over double the capacity of pylontech.

mcTrinity:
Good day house...

1) anyone has any technical view as to whether a Victron CC can be used with another type inverter. Have a client that's using Magnum inverter but need solar. Can't find Magnum CC (PT-100); looks like it's outta market. Next option I have is Victron SmartSolar CC, but I don't know if there'll be a downside using the Magnum inverter and Victron CC.

2) anyone here that has Automatic Transfer Switch for sale? I'll need like 4pcs

3) Biko, what's the difference between the Victron Multiplus and the Victron Quattro Inverters?

Thanks

Will you consider a fairly used PT 100?

Cells are still under processing at customs since 4th April, ANT BMS/Balancer still reporting transit (meaning not yet in naija). When the covid thing became serious in China, I figured the orders will be delayed so I tried to play smart, ordered a higher specs Daly on eBay late march thinking that it will at least arrive faster before the ANT BMS, see as God just dey laugh at me.
None have reached me till date!!!

PylonTech is rated >6,000 cycles at 80% DoD.

That is more than 16 years of life.

Personally if it lives over 10 years, I'd call it a very solid performance.

And the point was that any good LFP can do the same if similar care applied on pylontech is done.

Personally I do like to push up to 0.5C on my cells as that's the Koko with LFP but if I softly step on the gas like the settings on pylon am sure my cells which is rated >3500 at 0.5C could do over 10 years as well but nah... If this serves me 5 years at full capacity I will say it has done it's worth!

Did you source from battery hookup? Impressive pack you've got. I prefer top balancing.

I got these particular ones from Tech Direct on eBay, though I hear they are also called Big Battery. It was later I saw the ones being offered by Batteryhookup.com, almost same price as these. If I still had cash I would have bought from them also but I got my 38120 cells from them.

My only regret now is I should have coughed up some extra cash and done the gen 2 of the Nissan Leaf batteries. Those are from newer model cars with better percentage life in them. My thinking then was since I was going into a new adventure I should thread gently. If I know what I know now I for just go all in.

Funny thing, with everything I bought I haven't still much surpassed the budget if I was to go for Lead Acid batteries. So I think those guys saying its almost same price in the long run are correct. Although, when COVID-19 is over and I start acquiring all the additives like BMS and charger it will become higher than the Lead Acid budget.

Anyone with 8s of this active balancer for sale?

This is an awesome adventure. It appears you bought different types of LFPs, are they for different project or you just want to have a feel of all of 'em? You can buy your BMS and charger and use DHL or FedEx to ship 'em if you won't mind the cost. They appear to be the only postal agency working efficiently at this Covid19 era.

My brother na really adventure oo. I actually bought 3 types of batteries after watching a lot of YouTube on set ups and performance.

1.) 57 modules of Nissan Leaf
2.) 6 packs of BYD batteries
3.) 100 cells of 38120 LFP

Planning to use the first 2 to run my house on alternate days with an ATS changing them over (their rest days can serve as redundancy) while the 38120 will power my water pump, security lights & I'm thinking of throwing one fridge or freezer into it too though I'm not yet decided on that.

I actually didn't know DHL or FedEx is working in this period I would have bought the remaining things. Though I hate all those courier services with a passion as they use fake customs duties to cheat us out of our hard earned money. Too bad I don't know any other way of shipping down from AliExpress than using them. I dey always bleed whenever I know I'm stuck with them.

It's really a pain, I think I am going to start buying my parts in multiple pairs so whenever DIY users needs something I have they can get it faster, I hope other DIY LFP users can do the same. So instead of ordering a single BMS from AliExpress, order 2 or 3, that way someone who can't wait for AliExpress can pick it off you at a reasonable price margin.

You bought a 3.2v 100AH LFP for 1.2kUSD? Am sorry what's the motivation here? Even a 12v 100Ah battleborn with all the bells sells cheaper. Or did I miss something, is it 9units of 12x8AH?

I always laugh whenever I hear una say these batteries with bells and whistles cos all my years in inverter technology I never hear am before. Maybe it doesn't exist in the Lead Acid world sha.

You misunderstand that purchase I see. The total cells for that price are 108 with American shipping. They were sold in packs of 12 of which I now bought 9 packs. I intend using 96 for my set up to achieve a 24p4s battery giving me 12v 196ah thereabouts. I doubt if you can get Battleborn for that price.

It was a deal when I saw it sha and still looks like that to me. I saw all the batteries I bought as deals, maybe because I've always heard Lithium batteries are expensive or maybe I watched YouTube too much, anyway I have no regret as it stands.

I'm really interested in an alternate way of shipping things down from China oo, especially the ones that don't go through post office.

Okay thanks for clarifying, about 200AH 12v battery is not a bad deal, though if you go with the prismatic cells you can get a better deal of a very good battery on Ali. Currently starring at a 16 units of 3.2 150AH which will be 600AH 12v for 1.8k (+1k max for shipping)

Yup there are options
