Rennogy Solar Panel Which Wire Is Negative

Connect this cable to the mc4 female adaptor.

Rennogy solar panel which wire is negative.

Two renogy 100 watt suitcases. Imp refers to maximum power. I own two different kinds of solar panels from renogy. We re not going to mess with this wire at all.

The bare end of the negative extension wire will now be of negative polarity. The negative wire of the solar panel is terminated with a mc4 male connector marked. 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. My knowledge of solar panels you could fit in a thimble and still have room so please be as descriptive as possible.

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. The two current values that are reported on the solar panel label specs are isc and imp. There is no color code standard for solar pv panels like there is for ac systems. It goes into the conjunction box.

Any and all help in this matter would be greatly appreciated. Only your volt meter will tell you the truth. Make sure that the locking tabs snap in for a firm connection. Connecting several panels is done with an mc4 y branch and i use the like this one by powmr.

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. I do have the controller box with my panels and was told by renogy tech that i would need a 10amp in line fuse for this application. Pictures would be a big plus. These values are reported on the label at standard test conditions stc.

This wire has both a positive and a negative. Put the solar panels on top of your van where you d like them to be installed renogy solar panels installed on my van. Series means plugging a positive into a negative on the second panel etc. The right solar panel is connected with one cable to the left panel.

Parallel means combining all the positives separate from the negative wires.
