Question:

Hello - Regarding the Gopower Overlander Expansion Kit, if I already have one of these in place on my RV and I wish to add another to get to a total of 3 190w panels, do I need to purchase the three way GoPower MC4 connectors or can I use the included two way connectors? Thanks for your help!

Expert Reply:

Yes, since you already have two Go Power Overlander Expansion Kit # 34282182, you will need to add the MC4 expansion branch connectors # GP22VR and # GP82VR, as well as some extension cables to be able to add a third panel.

You should also verify that your charge controller is rated for the higher amperage for the additional panels.

I have attached a video showing you how to connect the panels together for you to check out.
