Talesun 330W 120 Half Cell Mono Solar Panel.

My setup is a little different but I can offer what problems I have run into and power generation.
I have a mix of the talesun and zshine bificial 385/395, with 36 panels I have been positive at with 5400w loads. One problem I ran into with growatts and it that took weeks of calls and troubleshooting. I was told only use two, which I saw between 91v+-v, the inverter will not run properly with that voltage. I had to re-wire all 48 panels which bumped it to 133v. I'm not sure if your 3000 will act the same or not but you are at a higher voltage. My inverter at 91,92,93v measured at panels would start to generate from pv but the sag would cause it to cut off, growatt confirmed it was due to unstable pv input when they checked the logs. Your panels are certainly higher than my original voltage so hopefully you will not see the issue.
I buy almost everything from signature but if you get a damaged panel you will have to pay for shipping all over again, plus the panel price inceasess and it gets very costly. I still recommend them for everything else as they are helpful in working with you.

This was posted from a diy member on calculating voltage increase: I need to check mine as well at the new voltage.

Use my calculator: https://www.wrdsystems.com/max_voc_calc.phpE.g., I have pushed my 410w-silver-mono-72-split-cell-et-solar-panel from SignatureSolar to 459W. That is 87+%. I would like to move this panel from my van to my TT.
I want to max the Watts for my van roof.
Will's test showed that the $50, 250W santan panels yielded 92%. Three of these will fit my van and could produce 690W for $150.
Has anyone tested or used the talesun 330W panels? I would install three for $485. I need to know what % of Wattage can be expected from them. So, 990W * % = ?Watts output.
Does anyone have any info on how many Watts I could get with the 330W panels? A simple % will do fine.
