MPPT range is 120-430v

Maximum PV wattage = 6000w

Maximum PV input current = 22A

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

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 panels wants to know if I can still add to already existing setup or make provision for an external CC.

Edrizz:




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

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

Oh ok.

Thanks for your response.

jonescosmos:

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 panels 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 panels

jonescosmos:


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

Ferdiwar:
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.

jonescosmos:


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

Edrizz:




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

jonescosmos:


@Bolded: are you referring to the battery?

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

Based on your pictures, your panels 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.

Ferdiwar:
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.

Ferdiwar:
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 panels as recommended after I get the extra battery.

Thank you.

Edrizz:




Price?

Oshomo12:


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

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

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

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

QuoteJust1nce:


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 Panels as a case study.
If it doesn't satisfy your needs, then upgrade to the SPH variant that offers ISC 33.8A, IMP 27A, 550V input accomodating between 6500 to 10600 Wp panels offering the same smart load functionality as the Deye. The 5kW version costs 1.3m and call it a day!

TechGeek777:


, your guess is as good as mine!

mctfopt:



I understand all these, the plan is to put as much PV panels 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 panels above 400w has Isc more than 11A making parallel impossible. The other alternative is to get lower capacity PVs, the space is very limited.

ibietela2:
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 panels and batteries.

Which type of panels 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

HeavenlyBang:


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 panel output you need, so you can essentially have a full charge by 1pm on average days.
