OK. Now I understand. When I saw 150ah 24v was why I wondered. If I had seen 300ah 24v, I'd have understood.

Saying that would have been incorrect right

Saipro:

Actually 3,060Wp (255W × 12) in 4s3p configuration. Besides, it's the instantaneous max seen that day. I remember having spoken of "cloud edge glare" here previously.

Seeing such isn't what fascinates me. What's impressive is the age of the panels versus performance. At 3pm on an average day, they output between 2.2kW and 2.5kW. On brilliant afternoons, >2.6kW. Midday yields are typically around 2.7kW to 2.9kW. It's phenomenal.

Thanks for the clarification, my sunfit is not doing so bad then(though not as much as Canadian in cost)..... Gives me between 900 and 1.3kW at 3pm and on great afternoons it has gotten as high as 1.43kW. My setup is about still 6 months old though, will see how it keeps up in years to come.

Renewable energy rocks!

So decided to try out quanta battery.
Looks really well made and high tech.
Though observed slight swellings on the 3 compartments of the battery.....is this normal.

Abeg quanta users should chook mouth

2ndly the boost charge voltage spec on it is 13.8v, while float is 13.5v, this is about the lowest i have seen. And would spell disaster for folks fond of mixing diff batt makes.
My usual long batts hv boost of 14.6v and float of 13.7v

The last set I got, I didn't notice any swelling, I tried to upload pictures, but not going. And pls don't exceed 13.9 for bulk/absorption charging, just follow the specs written for charging.

Note: what type/model of Quanta battery did u buy, mine is Amaron Quanta

earthrealm:


this your CC, e no no name or specs
folks should try and be intuitive when asking questions here, its quite tiring&discouraging to be asking for details back n forth, hence many will jump and pass the question

Apologies, I missed that.

It's a Felicity 60A MPPT charge controller. The batteries are not fully charged, the little charge it has is from the mains. I will try putting a heavy load to check it out.

I noticed that my post was hidden for sometime, I just noticed that it came up again and I got responses. Thanks to everyone intending to help.

I am planning towards backup overhaul and have been eyeing Quanta batteries but it seem there are many versions of it. For instance the one you've shared has Quanta inscribed while that of earthrealm doesn't, why all the inconsistencies? (am assuming you both bought originals?)

ojeysky:

Let's do the maths. If i do 11 years at 80% comfortably. You buy four 100ah between 60 to 65k.thats 240k to 260k.
Secondly you dare not do 80% otherwise you change your batteries less than a year. Let's say you do that and change batteries yearly. That's 260k × 11 = 2.86million.
Now let's assume your batteries did 2years plus, that's 260k × 5 = 1.3million.
Thirdly let's factor the fact that one battery starts misbehaving and we are compelled to change the whole four.
Now let's talk about faster recharge. I could go on and on but let's leave it here.

Everyman with his own opinion sha. You might like leadacid while some people prefer lithium.

So the 200ah version has different bulk charging and float charging voltages/requirements?

eleojo23:

Just design. Not sure about the charging parameters which I believe is same.

The Quanta spec sheet refers to a 'freshening' charge of 13.8v per 12v battery - I think same for absorb too.

This unusually low charge voltage gave me many sleepless nights but after much questions and research, someone here @McTrinity I believe posted a manual that indicated absorb up to 14.2v max was okay - I had always used 14.1v to charge so this information gave me great relief

That's good to know...thanks

The manual says 13.8v for absorb - another source I have seen says max 14.2v for absorb - I use 14.1v and have had great peace over many years and clients.

It is instructive that Amaron Tribal inverters from thesame manufacturer go up to 14.4v for absorb - makes me wonder how to reconcile everything.

For the picture posted there is some swelling on the 200Ah battery but this one you have posted is waaay out of normal range - very likely the batteries have been charged above 14.2v and gassed up a bit - gassing voltage is around 14.2v for lead acid chems.

Might be good if you addressed your charge algorithm ASAP before the batteries give way.

Thank you for the nice mention my Oga.

Please for next time, let someone else do the recommending while you buy the panels and any other RE equipment you need from me

People often forget that I am actually into the RE business full time, perhaps because I post freely and don't advertise much.

Saipro:
So, here's a retrospective review of product quality.

Amazing harvest from a 3kWp PV array (hit nameplate yield). More amusing is the solar panels are knocking 3 years. CC is a Victron Bluesolar MPPT 150/85. Display is via a Victron CCGX. Screenshot via Victron VRM.

Even I am wowed (which doesn't happen often).

Thanks NiyiOmoIyunade for compelling me to switch to Canadian Solar panels. Thanks Zeestone for the supplies.

I won't be doing 100ah, I will get 4 quality 200ah batteries for 500k and that should last me for at least 6 years if am doing 30% and maybe 7 years if 20%. I don't think that single lithium will still be doing fine after 5 years at 80% dod so I think the 11 years projection for that chap may be way too ambitious.

Everyman with his own opinion sha. You might like leadacid while some people prefer lithium.

Absolutely agree, especially for those who lack battery space perhaps. Thanks!

We've had talks on this issue over and over, with many against and few for Lithium family. For me, anytime and anyday, I will always go for lithium, especially LiFePo4, no matter the way u look at it.

Good analysis (on paper not service) BUT why would I need to do 80% DOD ? It's rare to have that type of need even when there's bad weather.

virgin battery, not yet hooked up to cc WHEN PIC WAS TAKEN
hooked up to CC, by 2pm today, i used 13.5v for float and 13.8v for boost. fangpusun 50D, 24V
the swelling appeared abnormal to me too,

@OSHOMO12, mine is quanta amaron too, 200ah. it has quanta etched on it as well. the battery looks well made, wudnt fvck with any other smf battery going forward, quanta all the way!!!, hope this preganat quanta i got wouldnt spoil my mind towards quanta batts though

i have had similr problem with a fangpusun mppt before, hence why i wanted to know the make.
did you adjust any of the settings recently?..like bulk/absorb/boost times
does it have a reset/ restore to factory button?, if yes activate it, that is what i did to my fangpusun, when i experienced similar issue

Imagine what will happen if you do 30% on two lithium 100ah 48v paralleled together. 8000 cycles

You don't mean it! My panels are configured like yours 4×150w in parallel but I use a 60a pwm cc. I am also expecting a 60a powermr mppt cc. My inverter is luminous 12v 900vac ecovolt.

Pls what's the make and model of your inverter. I am looking at future upgrade is why I need the 3.5kva. But I can hold on for now.

Don't know what I did wrong again that the bot had to restrict me from this section, hence the late reply.

The inverter is bough off of Aliexpress and mehn, it's like there is a price crash right now, damn!

Boss from what I can see in that picture, I am not sure you got the original Quanta o - I base this on the degree of swelling at the sides and most especially the look and design of the battery terminals.

This is perhaps thesame mesaage Oga Zeestone was trying to pass across jokingly.

Who/where was your source for these batteries please? This goes back to what I have been saying all along - source is very important for quality products - any product with a good name, people tend to make cheap duplicates of it and pass off as original.

If you could post a clear top view picture, clearly showing the battery terminals, perhaps I could say more.

Trippledots:


Whats the watt hour of the battery pack?

The capacity isn't indicated on it and I forgot to ask from the supplier, cos I assumed that it will be the peri-20,000mah that was of the types I had before. But this omw is smaller sized but with apparently more juice (as experienced from the use). I plan to even take it apart soon and see the innards.

I'll confirm from the supplier and get back to you.

zeestone99:

Yeah that will be interesting especially if I can get that within the 650k. However in this case, a 100ah battleborn lithium is 12V hence I will need 2 for a 24v set-up. Makes 1.3m.

I will rather do 2 rounds of 7 years with 30% DOD 400ah 24v Quanta at 1m.

It's like comparison of pwm and Mppt cos of cost

I don't think so really because 30% dod of 400ah should provide more backup time than 80% dod of 100ah under the same load condition.

Absolutely!

Everyman with his own opinion sha. You might like leadacid while some people prefer lithium.

Your analysis is good and accepted that as it stands today, lithium if affordable, should be the first choice of any AE enthusiast, I not exempted.

But come to think of this: There is every possibility that lithium can come much cheaper than all the offerings common in the market today, but do you know why merchants will rather pitch the price at the set point they put it? That calculation. Yes, that analysis you put up there. In fact, it's the same analysis that lithium manufacturers will use to justify a price set point and that is the set point passed on to re-sellers. Manufacturers and merchants exploit every opportunity for rapid ROI without recourse to some factors. But that's business and that's what it is.
