Rennogy Solar Panel Which Wire Is Negative

The two current values that are reported on the solar panel label specs are isc and imp.

Rennogy solar panel which wire is negative.

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 own two different kinds of solar panels from renogy. Parallel means combining all the positives separate from the negative wires. Only your volt meter will tell you the truth.

Make sure that the locking tabs snap in for a firm connection. Connect this cable to the mc4 female adaptor. These values are reported on the label at standard test conditions stc. The negative wire of the solar panel is terminated with a mc4 male connector marked.

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. There is no color code standard for solar pv panels like there is for ac systems. My knowledge of solar panels you could fit in a thimble and still have room so please be as descriptive as possible. Any and all help in this matter would be greatly appreciated.

Put the solar panels on top of your van where you d like them to be installed renogy solar panels installed on my van. The bare end of the negative extension wire will now be of negative polarity. Connecting several panels is done with an mc4 y branch and i use the like this one by powmr. Pictures would be a big plus.

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. In the conjunction box the left panel and the right panel are connected in parallel. Two renogy 100 watt suitcases. It goes into the conjunction box.

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. We re not going to mess with this wire at all. Imp refers to maximum power. Series means plugging a positive into a negative on the second panel etc.

The numbers on the multimeter screen should be in the 10 range of the numbers on your spec sheet.
