Question:

How do you wire two panels in parallel on grand design rv roof top if you don’t make a y-cable adaptor

Furrion unfortunately does not sell their connectors separately for some unknown reason and I haven't seen any Y-adapter connectors like you'd see with any other system. When it comes to connecting them together the only way to is in series (diagram below) which changes your voltage to 24v with the supplied connector when you purchase their panels. The only workaround for this is to use two separate solar controllers and essentially run each system separately to the battery.

If I was in this situation I would not get another Furrion Solar Panel # FR73SR, and would instead get the Go Power Overlander Solar Charging System with Digital Solar Controller # 34282181. You can still keep your Furrion solar system in place and just run this system separately. Both charge controllers will read the battery life percentage and adjust their charge accordingly so you won't have any issues with overcharging the battery bank.

This would also allow you to expand the Go Power system later on down the road if needed as well.
