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.

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.

Controller limits: Go Power lists a nominal 600W expansion ceiling for its supported 30A PWM controller arrangements. This is not approval for every three-panel layout. Verify actual module open-circuit voltage, summed short-circuit current, fuse sizing and controller model before wiring additional panels.

Replacement or separately needed roof parts

The following fittings are separate catalog products. A component listed inside a complete kit is not necessarily something a customer needs to buy twice.

SC expansion connector replacements

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.

Installation: Disconnect battery and solar supplies and cover exposed modules before working on connections. The selected roof fasteners, sealant and wire protection must suit your RV and exact system design. High-current electrical installation should be completed by qualified personnel.
