Rennogy solar panel which wire is negative.

Two renogy 100 watt suitcases. Put the solar panels on top of your van where you d like them to be installed renogy solar panels installed on my van. Isc refers to short circuit current which is the current value if the positive and negative solar panel wires come into contact with no resistance. It goes into the conjunction box.

The negative wire of the solar panel is terminated with a mc4 male connector marked. The right solar panel is connected with one cable to the left panel. We re not going to mess with this wire at all. My knowledge of solar panels you could fit in a thimble and still have room so please be as descriptive as possible.

The two current values that are reported on the solar panel label specs are isc and imp. If the numbers do not read in this range your panel might need replacing call renogy tech support to confirm at 1 800 330 8678 for the short circuit current test our panels are rated for 1000 watts per square meters. Only your volt meter will tell you the truth. I had the general idea of where i wanted the solar panels to sit on top of my van but without dry fitting them first i would have overlooked how the mounting holes actually lined up on the contoured roof.

Connect this cable to the mc4 female adaptor. There is no color code standard for solar pv panels like there is for ac systems. Connecting several panels is done with an mc4 y branch and i use the like this one by powmr. In the conjunction box the left panel and the right panel are connected in parallel.

The numbers on the multimeter screen should be in the 10 range of the numbers on your spec sheet. I own two different kinds of solar panels from renogy. Parallel means combining all the positives separate from the negative wires. Imp refers to maximum power.

The bare end of the negative extension wire will now be of negative polarity. Pictures would be a big plus. Actually there is a color code standard for dc pv systems and as the nec code book does not specify ac or dc the color code applies equally to both such systems. Any and all help in this matter would be greatly appreciated.

Series means plugging a positive into a negative on the second panel etc.
