6S2P. The voltage range of your MPPT means the panel Voltage must reach 120v for the CC to wake up, best voltage range is usually stated on the manual but most times around about 300-400v. If you use any configuration less than 6 in series, then your harvest will be poor as your CC will wake up late and sleep early.
By the way you did not include the Amp of your CC to help calculate the total number of panels it can accommodate.
Selah.

I've not checked the voltage range in the manual yet but if it's in that range, do you suggest I should go for 10S1P in order to arrive at 493V and 94A?
Mppt max charge current is 100A.
12pcs/6S2P is 113A.
I think few losses from 10mm cables could bring it down to probably 93A.
I've done 84A with 60A CC max charging current and 3S3P x 49.3Voc = 148V going into Max Mppt CC of 150Vdc with 6mm cables before. I was relaxed because I knew there would be greater loss due to the 6mm cables.

jonescosmos:
I would recommend you give us your Vmp and Imp also, because 49.3V x 11.6A /=/ 450W (/=/ means "is not equal to" calculations has to be fine for you to get it right. More so, do not hook up 12pcs of 49.3V in series to a system of 500V MAX, you might fry the system.
However, from all indications, a 6s2p might be the best choice for you.

Vmp is 41.5v
Imp is 10.8A
Is 10S1P better than 6S2P interms of waking up the CC early and sleeping late?
Downside: With my existing 450w Pv, I may be finding it difficult to really get a perfect setpoint as I'm struggling to push my array close to 6kw limit just to accommodate day time loads and fill up my battery at the same time.

Yes to the question.
Also note that there is a reason National grid transmits long distances using HIGH voltage: there is less energy loss and also affording the use of thinner wires as the case may be. So I have a basic principle with high voltage hybrid inverters. I will ramp up the voltage as high as I can first before thinking of parallel setup. Just be careful you don't break the voltage ceiling. If you break the amp ceiling, the Cc will just cap it at its capacity and continue working. If you break the voltage ceiling, then................
In extremely maxing out the capacity of equipment just remember that most times, the benefits does not always outweigh the risks.

First thing first, check your mppt voltage range before taking suggestions. Plz do this first.

Guess you didnt plan it properly from the get go, i mean the voc issh vis a vis the hybrid panel layout. hybrids perform best if the incoming Voc are above 280v. in one of my installs, am running 7s2p 330w panels with Voc of 43v.

i think at this late hour, you have 2 options

1. reconfirm your hybrid limits, and consider buying 2 additional panels, so as to run 7s2p

2. sacrifice 1 panel - sell or keep it aside...and run 11s1p with the existing panels you have already

The hybrid limit has been confirmed as stated in the previous page (120v to 500v). 7S2P x 450/48 is 131A which is greater than the Max Mppt charging current of 100A.
11S1P will give out 113A which is in considerable range as losses may step it down to about 95A.
Fortunately, I'm yet to buy the additional panels hence my reason for asking all these questions. I've bought the 5kw hybrid inverter already and I'm planning to buy additional 450w PVs to add to the existing 9 pcs of 450w before going into upgrading proer.

Thanks for your advice sir

Yes, TechLand is a trusted dealer, I transacted with them yesterday, communications was with the MD directly.

They shipped out my 26pcs of 600w Canadian Solar panels yesterday fingers crsooed I would recieve them soon enough.

And guess what, The man is from my state, hehehehe, small world.

Boss in the house please confirm that this seller is an authorized distributor of Jinko panels and also if they are trust worthy before I drop they boss contact whom I chatted with today regarding they Jinko Panels.

Anyone?

Someone once posted some sites on this and I can still remember GennexTechnologies dot com. Try and let us know

Thanks everyone for your advice.
I'll go for 10S1P configuration.

This is the best setup for you as per the MPPT of 500V Max ooo. You had mentioned 12pcs of PVs, please make sure you aren't gonna be setting up 12s of this PVs to this system. You might fry it. If you must use up all the 12 PVs, 6s2p is the way to go.

Just to clarify on this Max Amps, the Hybrid rated at 100A means that's the max it can suck out of a the input Amps supplied, So if you have a PV of 131A comming in, remember that the PV cannot supply if there is no demand. So even if the Inverter demands 100A of it's capacity from the PV, the rest 31Amp is not gonna be supplied.

This is different from telling your Inverter to charge a battery rated 100A at 131A or a battery rated 60A at 100A, of course it will fry the battery eventually.

But for Voltage, don't push your luck above the system ratings.

Also max voltage is different from working voltage range. I've seen some mppt at 450v.

I will reconfigure and make sure it doesn't exceed 450v. Your panels can exceed Voc on some certain cold days so having them near 500v is also risky

Very correct

Ok, most smart hybrids will throttle the current if its beyond its max spec, its usually exceeding Voc that causes outright damage.

Dep3nding on your risk tolerance, you can try 7s2p and see what happens. The 134amps you calculated wud only occur at optimum inclination and sunlight...which in real life rarely happens for longer than 5mins bursts.

If you wanna play it safe, just do your 11s1p and call it a day, or alternatively if you want to maximize everything consider buying a cheap standalone cc like powmr and 2 more panels. So u run 3s1p on the cc and 11s1p on the hybrid

The alternative idea seems good but instead of buying another standalone CC, can my Morningstar Mppt CC with 60A max input current, 150Vdc max input voltage with operating voltage range of 10v to 72v handle this job?

By direct user experiences, which is more efficient, Canadain Solar or Jinko or JASolar?

I haven't used any of these and I need to make a purchase asap.

Responses please.....

Go Jinko, PVs are so good. In no distant future, I foresee the "Canadian solar treatment". People buying junk and sticking a Jinko solar tape on it.

WOW, I see, thanks for this info.

Perhaps you should be more transparent by naming the products he intends to supply to you.
1, Brand of Inverter (very important)
2, Brand of Battery (Also 165,000x2 is not = #310,000 or #300,000)
3, Brand of Solar panels (Also 300w x6 is not = 1.6kw)
4, Others are at your dicretion.

Someone suggested previously here that the installer should put the names of various components he intends to buy for you.
You may still come back to seek help and it may be too late then.

Maybe your turenchi was too much lol.
You still didn't give me information on how to get the solution you mention and the cost of purchase and installation (I assume you deal in vicrton products).
What I'm saying is that in the absence of the ideal scenario you paint, what can be done to maintain balance with the present setup?
I have a 5kva inverter (I think its Famicare) a 100a mppt (Yohako) charge controller, trina mono panels 300w (12)

Abeg why did you get a charge controller for your inverter? I have the famicare 5.5kva 24v inverter and it comes with internal pwm solar charge controller.
