Can Two Solar Suitcases be used at same time?

I have one of these dual solar plug inputs installed on the battery box of my batteries. I currently only use one input for my Renogy Solar Suitcase (has its own charge controller.) However, a friend is offering me his Solar Suitcase .. so could I connect both of them at the same time? Would they each monitor the battery, would there be any conflict the with two independent controllers?

I have two Renogy 200W solar suitcases through one controller (Victron 30/100). I have not had both camping yet, but after some experimenting, they are working fine. I made the double connection using a cable combiner that I made, so it goes two series suitcase connections into a parallel connection back to the controller. If you want some schematics, PM me.

I have 200 watt on the roof and 160 watt suitcase which I connect directly to the battery with its own controller. I often run both sets of solar panels because usually the solar panel system on the roof of the Airstream is not necessarily in the sun all the time where we camp. The suitcase gives me the option then to track the sun with direct charging to the battery we have used this system continuously works fine maintains the batteries beautifully.

I have 300 watts on the canopy of my truck that I connect with a 25 ft umbilical. I have a Y connection on the end of the cable from my Renogy 100W suitcase that I can plug into the connection at the front of the trailer giving the ability to take advantage of any sun available when camping under tree cover here on Vancouver Island. Works great.

A qualified yes. My 2014 did not have a connector to use. I added a Anderson 50a polarized connector direct wired to the battery. Used the Renogy charge controller supplied with my first set. When adding the second panel without controller I purchased a 30a charge controller. Using 10ga garden wire and anderson connectors I made a “Y” connector and extension cord to allow separate panel placement and the choice of parallel of series connection. I can park in the shade and place panels in the sun.
