The Go Power OVERLANDER 200W is a rigid rooftop solar charging kit with a 30A Bluetooth PWM controller. OVERLANDER-E adds another 200W framed panel to an appropriately sized existing system. This illustrated guide separates the included parts from optional mounting, roof entry and replacement connectors.
How the Overlander kit charges RV batteries
A rigid solar module supplies DC power to the PWM controller. The controller manages charging of the RV's 12V battery. An expansion panel can add current through a matched pair of solar branch connectors when the existing controller, cables and roof wiring have sufficient capacity.
Which parts are included in each Overlander box?
| Component | OVERLANDER 200W kit | OVERLANDER-E expansion |
|---|---|---|
| 200W framed panel | Included, one panel | Included, one additional panel |
| 30A PWM controller | Included — GP-SB-PWM-30-BT in the listed kit; verify older units | Not included |

The 200W framed module is specified at approximately 20.8V maximum-power voltage and 24.3V open-circuit voltage, with a nominal panel size of 59.1 × 26.3 inches. Go Power offers more than one Overlander panel generation, so the exact module marking and controller revision matter when combining panels.

These exact branch models have opposite connector-gender arrangements. Their presence in our catalog does not establish that every Overlander kit generation uses the same connector body; compare the fitted plugs.
Original Go Power kit checklist and wiring drawing
Go Power's RV Solar Power Kits manual has an Overlander parts checklist and a separate Overlander + Overlander-E system diagram. Use its drawings for the positive and negative branching layout, panel grounding, rooftop entry and battery fuse placement. Compare the illustrated module generation to the label on your kit.
