Note:
This installation guide
does not list all possible
variations of available
solar modules. This
installation guide will
address the assembly of
standard Go Power! RV
Solar Power Kits, which
contain one, two or three
solar modules connected
in parallel for a 12 volt
system. Expander Kits
are available to add solar
modules to an existing
system.
1.4 Weekender SW / Weekender HD / Solar Elite/ Solar Extreme Installation
Refer to specic product manuals included in kits for correct product installation (ex. inverters, chargers and remotes).
2.0 Wiring the Solar Module and Power Cable
Please follow the directions in the appropriate section, depending on which kit you are about to install.

3.0 Wiring Modules with MC4 Cables
RV Kits with MC4 cables contain a potted or sealed junction box with a positive and negative MC4 connector. This is
referred to as an MC4 junction box. MC4 connectors are either positive or negative and each connector has its
polarity symbol embossed close to the connection point. To extend a cable from an MC4 junction box, a polarity
opposite connector must be used. E.G. a negative connector must plug into a positive connector in order to extend
it. Please remember, the polarity of an MC4 cable wire run is the polarity symbol on the connector closest to the MC4
junction box. It is advisable to attach a polarity sticker to the positive extension cable in order to avoid confusion.
3.1 GP-RV-80/95/155/Weekender HD/Weekender SW
Single Module System/MC Junction Box
RV Kits containing a single module with MC4 cables will be equipped with a single MC4 power cable that has both a male
and female MC4 connection. This cable is meant to be cut in half leaving you with a 25’ cable with a male MC4 and a 25’
cable with a female MC4 connection. Refer to Diagram-1, “MC4 Power Cables for RV Kits.”
3.2 Solar Elite
Multi Module System/MC4 Junction Box
RV Kits containing two modules with MC4 cables via an expansion kit will be equipped with a 50’ MC4 power cable, a
negative MC4 parallel connector and a positive MC4 parallel connector. Refer to Diagram-2, “Wiring Parallel Modules
with MC4 Cables.”
3.3 Solar Extreme
Multi Module System/MC4 Junction Box
RV Kits containing three modules with MC4 cables via two expansion kit will be equipped with a 50’ MC4 power cable, two
negative MC4 connectors and two positive MC4 connectors. Refer to Diagram-2, “Wiring Parallel Modules with MC Cables.”
3.4 GP-RV-80E/95E/155E
Expanding to a Multi Module System/MC4 Junction Box
RV Kits containing two modules with MC4 cables via an expansion kit will be equipped with a 50’ MC4 power cable, a
negative MC4 parallel connector and a positive MC4 parallel connector. Refer to Diagram-2, “Wiring Parallel Modules
with MC4 Cables.”
3.5 Modules with MC4 Connectors Wired to a Non-Potted Junction Box
Please be aware that some modules are equipped with MC4 cables and a fully functioning non-potted Junction Box. In
this case, it is recommended that the MC4 cables be used as described in Section 3. Do not connect the positive and
negative MC4 cables from the same junction box together; this will short circuit the module.
