Hi. I was going through some things back in the day with Covid and work and never got the solar installed (basically throwing money away as I already paid for 90% of the solar items). Now it's two more years gone, just hit 60 and realized that the aches in pains increase like my solar...

Marine wire is larger for a given gauge size, up to 12% larger in some sizes. If you choose to use SAE wire, you must allow for this difference when using commonly available marine voltage drop tables.

Beyond being tinned, marine cable is larger than say automotive cable at the same size. So, 6 AWG marine cableactually contains more copper than 6 AWG automotive cable. The more copper, the better the current carrying capacity of the cable. Marine cablealso carries a pliable and durable PVC jacket

I got 100’ for about $110 shipped. It’s 10/2 Anchor wire and it says it can handle UV. I read that the Marine Grade wire handles the amperage better as in it seems Underrated for its actually amp capacity but I could have read this wrong. The wire looks good. Here are the specs...

Wow I am an idiot... if my inverter is 8000w then how can it handle the Pnom of 27x340w= 9,180w or just because the 9s3p voltage is 528v at 26a everything is ok? A watt calculator for DC said that the 528v and 26a would equal 13728 watts??? 17a @480v (8s2p) = 8000w yet based on the panel Pnom...

In the final build it should be like this: 27 Panels configured as 9s3p for 528V and 26 amps. And I think this post is done unless I am missing something

Ok I had read both of the articles before I started the original post. It helped a lot but it doesn’t always sink in. I guess the best thing I can do is just do a 9s1p South facing for now and connect the other 5s (South facing) with the 4s (East facing) which only get full power for 1/2 the...

Some guy named Svetz ? is the reason why I joined this forum. I was searching circuit info which led to your well illustrated article “Solar panel strings: Parallel & Series explained”. I still need to understand about combining different DC voltages for the different voltages of each set of...

10s3p = 586.739V and 26A

Thank you so much. I have a lot more studying to do. I believe I had read one of the listed recommendations but I will check again. Again, thank you. Sometimes I think the nomenclatures used here and over in Asia might seem differently worded. I realize that the terms like Voc shouldn’t...

Odd question as I am getting confused about combining series to parallel totals for one string. I am trying to make sure that I have the necessary amount of panels to ensure the Inverter's Start Voltage of 360V is met and not input the maximum DC voltage of 600V in the winter by using the...

Doing some math in the morning. Read the article. Thank you. I hope I can make this work.

Hang in there... I am doing a Grid Tie not a battery charging setup. I will look at the info you mentioned with fresh eyes in the morning. Thank you again! This is great help. I did just order the 10AWG Marine UV grade but I plan to protect it properly anyways.

Thank you for your information. I will check any links soon. 1. So I guess 14 panels in series would give me 595Vdc and as much as I would like to add the last panel to it that would top the 600Vdc rating. Is this correct? Or is it rare to have panels actually producing what they say during...

Hello! First timer here. I am trying to install my panels this April and I am ordering the PV cable and MC 4 connectors and I wanted to hear if I have my math correct or wrong please. I am using a Rensola RePlus 8000TL Plus Grid Tie String Inverter and SunPower Performance Series...
