No idea. That's exactly how my inverter looks like. Most of these companies do rebranding. It might even occur that both of them are not actually the real owners. Just added their own name to d inverter.

Okay thanks. For your Techfine CC, does your seller have 80A variant?

Do you know if the Max 3200W/48v for the 60A variant can carry Jinko Half-Cut 380W * 8 (3040W)?

Jefferyzz:
I use Solar alone. Incase u plan on changing urs with AC. D inverter has 30a AC charger

Ok I get

Thank yo

Specs of your 250w panels....multiply the VOC by 6(number of panels available). If it's within your mppt cc maximum voltage, you are free to connect all in series

I don't remember the spec of the 250W panels. Its been a couple of years since they were installed

I took the reading again at 12:45pm and got the following readings
Isc=12.5A
Voc=96V

I have installed a 3kva hybrid with max pv input of 500v for someone last month, although the pv installed is not so much[b] (4 pcs of 325w in 4s configuration) [/b]but so far it has been ok. at a point, one of the internal cooling fan stopped working and something blew up inside, so I took it to their facility at Okota where it was repaired on warranty.

I've since re-installed it, and the client couldn't be happier.

#@Bolded, this is a very poor/inefficient setup, for a hybrid hv inverter of 500v voc, the avg voc of a 325w panel wud be about 42volts, so you would be sending about 160volts...which will drop to about 110volts when the inverter is working---. what is the nominal input voltage of the inverter?. whats the make/model

Good Afternoon Guys, Please is eight units of 280watts Panels ,Ok For four 220ah Batteries (3.5kva 48v Inverter)

8 is Good starting point if Grid is mostly available and if you don't deep discharge your batteries, I would recommend 12 as minimum.

There is no straight answer to this.
It depends on a lot of other variables, like your load, phcn availability..

Lastly kazeem installers are fond of this 2s4p design for a 48v system.with standalone CC. This is not an optimum design, as the Vmp is low...
You are better off with a 3s3p setup...

Unless its for a hv hybrid inverter, and he wants to do all 8 panels in series----which i doubt, as the whole setup screams kazeem

@techgeek, are you sure?..most hv hybrids have 240v as nominal input voltage.

@trippledots. Really
A huge error on your part if true...am suprised it even generated any meaningful output.
You are an old hand here...
Anyway, waiting for ur clarification

No. D cc max DC input is 150v. Ur panels voc is wat will determine how u will arrange it.

If you can, add additional panel and connect 3s3p.
My setup was 8 270w initially and I rarely get above 1000w solar generation. I added a panel recently and change it from 2s4p to 3s3p. The peak instant generation has jumped up to around 1.8kw. That's more than 50% increase

All panels are not the same. Some panels have low amp high volt.

Most likely, because Felicity IVEM3024 is the 3KVA variant that will give such HV.

IVEM3024 Sepc:
Nominal Voltage: 360
Minimum Startup Voltage: 120
Maximum Voltage: 500

My oga,

Please I sent you a PM the other day but I didn't get a response. I want to get the external charger.

There are no details on my batteries as regards rating on my batteries and inverter.

I posted the pictures earlier too.

Thank you

I responded to your PM. Check again. I saw the pic you shared and indeed, there was no information in it. You may have to ask around, but i doubt you will have any issues charging it with a 40a charger.

Penuelseun:
Yes I do

Sent you a PM!

Ok gu3ss the minimum start-up volatge of 120v is what is keeping it going, but am fairly certain the performance would be sub optimal

Jefferyzz:

While this is true, its not common.
It would be super hard to see any 350w panel with VOC above 45v

Already sent you a reply, but you can reach me via the number on my profile for faster response

Hello please I need help here, I have a battery 100ah*2 which indicates it’s a sealed rechargeable battery(no indication if it’s gel or agm) now my inverter requires me to select either tt(tall tubular battery) or agm, please which option should I select thanks in advance

HilcomTech:
Good morning gurus in the house,

I installed my PV array in the series/parallel format as shown in the picture and it gave the following readings at peak

Isc=12.25A
Voc=96V

I am considering changing the arrangement to complete series since the MPPT CC can take PV input voltage of 230V

Would that be advisable?

Rule of thumb for buck converters (which technically all true MPPT controllers are) is that you get max conversion efficiency at about 1:2 of output to input voltages, meaning your present configuration may be the most optimal so long as your cables are sized properly.

Jefferyzz:
No. D cc max DC input is 150v. Ur panels voc is wat will determine how u will arrange it.

The (Voc): 41.30V.
Full Specs ==>
Maximum Power(Pmax): 380W
Maximum Power Voltage (Vmp): 34.74V
Maximum Power Current (Imp): 10.94A
Open-circuit Voltage (Voc): 41.30V
Short-circuit Current (Isc): 11.68A

On the other hand there's a 100A Felicity CC with below details,
Max Pv Input Voltage = 195V
PV Array MPPT Vol Range = 160-170V

My question now is, can Felicity 100A with above spec take the 8 panels using 4s2p config?

Or should I use Techfine 60A/80A with (Max PV Voltage: 150V) and go for 9 panels using 3s3p config?

Please I need the one that will produce optimally so I know the total number of panels to purchase and the exact CC to go for.

How is it inefficient? Your estimate of the voc is spot on but mind you the Mppt kicks in at 120v. The load is sized properly to ensure the battery is not been depleted plus grid charging is active... Any other PV configuration would fall below the minimum PV input Voltage.

That should be expected, people forget that therw is always a tradeoff somewhere. Reducing your panels from 4p to 3p was the game changer.

Correct .. it's an IVEM3024

For the client's needs it is ok, but there is still room for more harvest with additional PV done when the client is done with his roofing.

41.3v x 4panels=165.2v < Felicity 195v so Yes, the Felicity should work fine with those specs and config
