You can get Jinko or Longi 450w to 475w and do 12 or 14 (6s2p or 7s2p)

mctfopt:


MPPT range is 120-430v

Maximum PV wattage = 6000w

Maximum PV input current = 22A

Ferdiwar:
Isc or Imp? Cause but are totally different.

High frequency SRNE hybrid inverter with 500v, 13amps... the amperage of the PV input is rated at 13amps

Ferdiwar:
Please I need your input on Deye inverter specs.

Mine is the 5kw with 2 MPPTs, the specs reads;

Max PV input power of 6500w.
PV input voltage 370vdc (125vdc - 500vdc).
PV input current 13Adc + 13Adc.

Now I understand that the input current is 13A for both MPPTs but I don't know if same is the case for the input voltage.

My question is "is the 370v (125v - 500v) for each of the MPPTs or a combined voltage for both MPPTs"?

I want to increase my s wants to know if I can still add to already existing setup or make provision for an external CC.

The 2 MPPT trackers are 6500watt apart and the 370v (125 - 500v) is for individual MPPT tracker n not combined. So in total, ur 2 MPPT trackers can take 6,500watt x 2 = 13kw all together

If the 13A is Imp you should see a higher amps for Isc which is the max the inverter can take in case of a short circuit from the s.

You can get a higher wattage like 550w to 580w with VOC lower than 50v and series them up to 10pcs.

Please note that your 6500W Max PV is the Combined MPPT PV Power, So each of you MPPT is Rated 3250W, manufacturer does not need to spell this out to you

370V is the nominal voltage for each MPPT, of course you can go all the way to 500v PV but don't exceed it by 1V.

Your best practice for your Inverter is for you to run 14x625w Jinko s in a 7 series on each MPPT setup. Theoretically that should give you 8750w @ STC. But you will get something around NOTC spec of the s

Oh ok.

Thanks for your response.

The bolded claim is not correct sir. 6500w is the combination power of both MPPTs

Ferdiwar:
Oh ok.

Thanks for your response.

Please post the Spec Sheet Label or Sticker of your Inverter.

Thank you for your response much appreciated.

I currently have 5x 570w Longi on the PV1 and 5x 625w Jinko on the PV2 which are both doing great.

Will add to more 2x 570w or 580w Longi and 2x 625w Jinko to the setup as I plan on adding a 15kwh to the already existing 5kwh.

@Bolded: are you referring to the battery?

Is your Longi a Hi-Mo x5 or Hi-Mo x6?

Based on your pictures, your s are obviously operating @ NOTC or less. So I recommend you add 3x570W Longi on PV1 and 3x625W jinko on PV2 respectively. this should get you around 6000W-6500W which is the Max your 5KW Inverter can do.

jonescosmos:

Maybe Deye is different then, cos I'm 100% aware that for SRNE, their 2 MPPT trackers are independent of the max input pv of 6500watt, 125v nominal voltage and 500v max pv n attached is my proof

Hmmm... Now I'm confused 🤔

If below is to be true that means the the 500v is the combined max voltage of the 2 MPPTs.

Meaning each MPPT is 250v/13A totalling 6500w for both.

Please clarify ify assumption is wrong.

The principle is them same, the picture you posted is for 8.8KW, 10KW and 12KW Inverters, And SENRE has done justice to what i said earlier about manufacturers not telling us about the power of individual MPPTs .

So it's safe to say that the 8.8KW has a max PV power of 11000W, the 10KW has 11000W PV Power and the 12KW has 13200W PV power respectively.

On the side of the Deye 5KW inverter it has a MAX Power of 6500W as clearly indicated on the Spec Sheet. So each MPPT is 3250W

Yes the 15kwh is battery (DIY EVE LF304Ah or EVE MB31 314Ah cells).

They are the Hi-Mo 6.

Ok I'll work towards the additional 6 s as recommended after I get the extra battery.

Thank you.

No sir Voltage is constant because the 2 MPPTs are in parallel. Reason why their Amperages will rise (13A+13A) or (17A+17A) Max.

So each MPPT has a Max Voltage of 500V DC

Ok, so let's take your total load to be 4KW, Plus 15KWh battery = 19KW
Your s Power take 6KWp.
On a sunny day, you need between 3-4 hours to fill your battery while powering your load at the same time. and once your battery is Full, the solar energy is far enough to power your load till sundown. See my Screenshot below

This is like my best thread on NL. The wealth of knowledge here is immeasurable. Thanks to everyone that contributes in one way or the other.

In the manual, did they work with lower capacity s?

I don't want to assume they never intended you getting near that 6000w in the first instance.

They just stated the maximum PV wattage is 6000w, how you get to that is ok if you don't exceed their PV input current

Ferdiwar:
You can get Jinko or Longi 450w to 475w and do 12 or 14 (6s2p or 7s2p)

Those two s you mentioned have Isc of more than 11A each which will exceed the yeye 5000ES Growatt's maximum PV input current of 22A

Ferdiwar:

Are the jinkos better placed than the longis in of orientation?......based on the numbers on the pix, it seems the jinkos are doing better in of generation

Me think you're expecting too much from a 5kW / 450V input inverter that can do 580 * 9 at NOCT which gives around 5200+ out of 6000 available. If you're scared of NOCT, then STC can do 440 * 11 which give nearly 4900; using Jinko s as a case study.
If it doesn't satisfy your needs, then the SPH variant that offers ISC 33.8A, IMP 27A, 550V input accomodating between 6500 to 10600 Wp s offering the same smart load functionality as the Deye. The 5kW version costs 1.3m and call it a day!

Already bought the Growatt. Thanks for your input.

TechGeek777:


, your guess is as good as mine!

🤐🫢

mctfopt:



I understand all these, the plan is to put as much PV s as I can per growatt. I'm sort of annoyed I can only do less than 5kw when said inverter can do 6kw.

Growatt has a maximum PV input current of 22A. I'm unhappy I can't run parallel as most s above 400w has Isc more than 11A making parallel impossible. The other alternative is to get lower capacity PVs, the space is very limited.

You sure you are actually reading the recommendations and advices given?? Calm down and read them o

Good evening, please I want to start buying materials and keeping them instead of waiting to do it all at once.

Which should I buy first? I was thinking of the growatt SPF ES5000, then s and batteries.

Which type of s should I get and battery type too.

Any other recommendations are welcome, especially ways or materials that will not cost me a lot but still be able to work

Thanks

Start with knowing your peak typical load so you know what inverter to buy
Then calculate how much storage you need for your load at night (I'd recommend night load * 15h to know the battery size you need)
Then I'd say divide your battery size by 2 to know the output you need, so you can essentially have a full charge by 1pm on average days.

I have not made any comment here in years.......
How am I not going to make this an epistle....

Thanks for your wonderful contributions. I think you are right on this one. But not entirely 100%.
The OEM did not state the rating of the mppt tracker in their spec sheet. I strongly suspect that they chose to be silent on this for a reason. They know what they are doing.....
I did a couple of deye installations of recent in two different places. I had to put 8 units of original Canadian solar 650W s on 6Kw deye inverter and I ran into a dilemma doing the job. All s installed together in the same angle.
If I split the s into 2 strings, the inverter will struggle to wakeup or run during the day. To make matters worse, if I choose to do the second string, I will have to run extra pair of 10mm cable over 40meters. At 5000naira/meter that is extra 200k.
I was very angry and furious with deye on why they choose to be silent over this very important matter.
Well.... i took matters into my own hands. I put all the 8 s on one string and into one of the mppt tracker knowing fully well that I am not going to break any of the rules according to their spec sheet to avoid voiding the warranty.
Kw, voltage and current all slightly below spec rating even on a single string.
On commissioning, we were getting well over 100amps. In fact I had to limit the output current at some point to protect battery. Installation had been running for several months without any issue.
My conclusion is that the 7.8Kw norminal rating for a 6Kw deye is for the internal charge controller and not mppt/2 as i also previously thought. After all, they did not state this in their document anywhere.
Now... their could be reasons where you want to use only one mppt like in my case. Their will also be many reasons where I will want to use the 2 mppts like if I have enough s, if cost of running cable for another string is no issue or if the installation is such that sun shines on one part of the roof in the morning and the other part later in the day and i need to take advantage of the two sides.
Hope this helps.
