Question:
I have the go power kit with the 2 190 go power panels and the 30 amp go power controller. What do I need to expand with 2 more 190 amp go power panels.

Hi Scott; the first thing you need will obviously be the panels. You can either add two of the Go Power Rigid Eclipse Expansion Kit - 190 Watt Solar Panel # GP47MR or Go Power Overlander Expansion Kit - 200 Watt Solar Panel # 34282182. These come with branch connectors but you will also need # GP82VR and # GP22VR to allow you to run all four panels together.
The panels are 10 amp so moving to a fourth will also require adding/changing your solar controller since it will take you over 30 amps. You can add in the Go Power MPPT Solar Charge Controller - 30 Amp # GP72RR or trade out your existing 30 amp for the 60 amp # GP54FR. If you would rather not swap out the controller or add an extra one you could add a single panel to your setup using the existing controller.
