I was at your office yesterday morning to pick up 2 REC 330 watt solar panels... I made the 1300 mile trip to see some property that I recently bought in the Holbrook, Az. area... and saved myself a couple of Hundred $$ shipping by hauling the panels home on my old VW Jetta Diesel (51mpg)... I left NAWS yesterday morning about 09:00 after loading the panels on a small towing rack on the back of the car... I got back home a few hours ago... I hope that Downpour I hit 50 miles from my destination didn't hurt any electrical components... otherwise everything should be fine ! Very pleasant transaction with Adam and Jason... Jim was great helping me load the panels on the car too ! I didn't get the name of the guy at the reception desk...he was very nice also !
I have 5 series connected panels on my van and often one of the panels are completely in the shade but because the panels all have bypass diodes, the system works fine. I didn't hear you mention bypass diodes.
3s1p..... If I am correct this means 3 panels in parallel.... But what drives me crazy is why is this called 3 series 1 parallel... Am I correct?... If yes then why not just call it 3 parallel?...thanks
1 x (Panel + Panel + Panel). You can think of the _plus_ symbol as adding the voltage in series and the _times_ symbol as the parallel symbol which does not multiply the voltage. If the specs for your panel is 45VDC @ 11A then 3s1p would produce 135VDC @ 11A = 1485W max. If you add another set of three panels and then connect that string with the earlier one using those Y-shaped connectors then this would be 3s2p, 135VDC @ 22A = 2970W max. Notice how the current output doubled since we used those Y connectors to do the parallel thing. If you removed the Y connectors and put a long string of all six that would be 6s1p, 270VDC @ 11A = 2970W (again). Just because you can do it, that doesn't mean you should do it. Personally, I have a Victron MPPT 150/100 charge controller so I need to keep the input voltage below 150VDC. So that 6s1p for me wouldn't work since 270VDC is greater than 150VDC. But I could do that 3s2p as described since both voltage/current numbers are each below 150 and 100, respectively. Hopefully that makes sense.
1) Pretty sure you mis-gendered those connectors. The male-looking connector from strictly looking at the plastic housing actually contains a _female_ conductor so the whole thing is called a "female". The positive charge is usually connected to a female conductor for the sake of safety in electronics. Look inside the other plastic connector and you'll see a male-looking conductor which then makes it the negative/return side of things. 2) I like to use red/black or red/white wiring in my installation just as another reminder of which side is which. Red in all cases is the positive connection. 3) I think a good follow-up video would be to highlight a single Victron charge controller by its model number (150/100, for example) and then describe the maximum amount of a particular selected solar panel for this controller and then talk again about series/parallel options for same. Those numbers imply the maximum voltage/current it can take. So discuss some strategies for this single controller.

How did it go?

The two 330 watt solar panels are still sitting in my shop waiting for nicer weather in the Spring !
Good luck !

This helped tremendously
Well done!!! Thank you for this video.
Thanks did help me.
thanks! very helpful
Is it the voltage that charges the battery or the current that charges the battery?
Assuming that you're connected to an MPPT controller then it's both ( _voltage x current = power_ ).
