hello,

I have 1 x 100 watt solar eclipse suitcase with an attached Adventurer 30A PWM controller and 1 x 100 watt solar eclipse suitcase without controller. I attach the unit with a controller through a side port connected to my 2 x 220ah 6 volt deep cycle batteries.

question: how do I connect the other suitcase without the controller to the controller so I end up up with 200 watts going to the batteries?? I don't want to buy another controller.

parallel, ie ya can hook the extra suitcase to the PV input on the the controller along with the wires of the other suitcase.

A short pigtail form the controller with some sort of plug and corresponding mating plug on the extra suit case and ya just plug it in when ya use both suitcases.

Thanks rabird,

Regarding fusing the setup......I was going to use a 30a inline mc4 fuse for between the 30a Adventurer controller and battery, but was wondering what inline mc4 fuse for between the 4x50 watt panels that are connected in parallel?? 20a or 30a??

I would not fuse the panels based on this

www.civicsolar.com/support/installer/articles/when-fuse-when-not-fuse

I believe the math is something like 2.9A (Isc) x 3 = 7.8A x 1.25 = 9.75A which is less than the 15A panel fuse rating.

Controller to batts, 10g wire, 30A, of course smaller wire would require a smaller fuse.
