Dear Community
I need your help in getting error code in my inverter resolved. The inverter is 6KW and based on Voltronic Power main board and other components. For past 3 days, I'm experiencing fault code 09 (Bus Bar soft start failure). The problem I'm facing is as under
1. When shut down, It...
Thanks for your response.
What about other questions regarding the bifacial gain observed and could this bifacial gain increase the VOC as well? I have posted the real time output images if inverter where we can see that the output was around 5330W (against installed capacity of 5220W). Images...
I have already used 6mm2 wire during installation of system just for the sake of future enhancement.
I'm confused either to hook only one more panel to reach 5800W or hook 3 more to reach 7000W and get around 6kw output from inverter (as it is rated 6kw). Actually, it is grid feeding inverter...
I have 9 panels right now. So, what you mean is that I should bring down the 9 panels in series and put the -tve and +ve terminals of solar array with mpp1 and st same time with mppt2? In this way it would be safe having Isc above 26A? I'm understanding right?
Hello Hedges
"Nominal DC/Max DC= 360/500 VDC", 500V / 434Voc = 1.153
What's meaning by this and how to use this ratio?
Secondly, as shown in attachment, yesterday, it was over caste, cloudy day. I noticed that around 11 am, the system reached 5330 W (Installed capacity is 5220 W). Since, the...
Hi everyone
I'm going to add one more panel to already installed panels (9 panels and all connected in series).
The panels are of JA solar, Deep Blue 4.0, JAM66D42-580/MB bifacial N-type.
I'm unable to understand if I could hook the new panel with the existing panels in series or I have to make...
Dear Hedges
I need your opinion about connecting my 9 JA solar panels (580W) with Kostal Piko 4.6. The details of the inverter and panels are as under
JA solar specs
Pmax 580
Voc 48.18
Vmp 40.42
Isc 15.21
Imp 14.35
Inverter specs
VDC Max 1000
Rated vdc 600
Isc 13.8 (mentioned on inverter)
Imp...
I'm running 9 panels already for a couple of months and it giving great results (achieved 4960 watts on 24th March). I'm interested to get the inverter to maximum of it's capacity (7000W). So, exploring the options to hook three more panels. But at the moment, I have only one panel at the disposal.
Inverter Specs are here

No shadow could hit the array (No trees, or other object around, which could shade the panels) as the panels exposed to Sun throughout the day.
So, you recommend 5S2P if no shade hits otherwise 9S...

Out of curiosity, I had to give a final test. Attached are the today's test results. Hooked 6S2P panels making ~7000W. The inverter drawn a maximum of ~26.5A and produced ~5900W (6000w designed capacity).
No beating or any error was observed. So, I wonder, why 7S2P gave...
Let me explain my position
I haven't problem with inverter's voc as it is beyond the 9 panel voc (433vdc). I have issue with inverter's Isc and Idcmax which are 13.8 and 11.
Q1. Panels have Isc of 15.2A. so, will it hurt the Inverter or not?
Q2. If the inverter is happy with 9 panels in series...
Dear All
I have 9 panels of JA solar with specifications mentioned in attachment. I'm getting a Kostal Piko 4.6 grid tied inverter who's specs are also listed.
Can anyone guide me if I can really hook these 9 panels with Inverter? The reason for asking this question is the difference in IDCmax...
Hello guys
I have the following issue
1. Single Phase 5KW Hybrid inverter with 5KW solar panels (grid export enabled ).
2. 5KW On-Grid / Grid-Tied inverter three phase with it's own 5KW solar panels: mainly for the purpose to feed to the grid. (The grid tied inverter isn't micro inverter, I...
So, how would the connections be made? Three phase would take all four inputs from energy meter.
I would take 1P and 1N from merer for running utility load. Should the single phase hybrid be connected with this utility line? Or I would take separate lines from meter for this hybrid inverter?
Actually, I have already gone through a problem with another inverter (hybrid one) who's charge controller failed and is now under repair. That inverter supported Isc of 27A and panels were 6S2P panels were hooked with it. Since, panels had Isc of 15.2 (30 in parallel mode), the Inverter...

Here is an experiment which I did.
These two images show one string consisting of 7S. PV voltage vs PV power, May 20th 2024. At peak production, the voltage remained close to 260-270V. Power produced was around 3400W.
Now in this image, booth strings, 7S2P, were...
One of my technician suggested me to buy one more panel to make it a series of 10 panels. The new panel should have Isc less than or equal to 13.8A
He says, when in series, this panel will bring down the current of all panels equal to the lowest panel current thus, the inverter will be able to...
Hi Hedges
I have a customized structure, so, the orientation of the panels will be same. as the inverter can support 7000W PV, I can hook 3 more panels to make 6+6 strings. Since, the inverter is capable to deliver 6000W, what if hook only one more panel and make two strings with 5 panels. will...
Dear @Hedges
I'm using this inverter for grid feeding only. Haven't attached batteries or utility load with this one. Only purpose of this inverter is to share with the grid whatever it produces.
Isc rating of this inverter is 27A
My panels have Isc of 15.21A.
I have 14 panels at my disposal...
Dear @Hedges and @zanydroid
On advice of my installer, I went to see another system similar to mine. Same Panels of JA solar with similar electrical parameters. Inverter is also of same company as mine with similar specs.
Installer installed 10 panels as 5S2P. This setup has only one difference...
