Hey Brandon,
The etrailer Solar Expansion Kit # e49FV has a 195 watt panel which wouldn't mesh well with the 100 watt go power panel # 34272635, even though they both use the same connections. When expanding solar you'll want to use same wattage rated panels otherwise the higher rated panel will lower its output to the same as the lower rated panel. This means instead of getting 295 watts of power coming in you'd only get 200 watts because the 195 panel is dropping down to 100 watts.
The # e49FV is a full kit so you could still use it and just wire it to the included charge controller and run it separately to the battery bank. If you just want to add a panel to your current Go Power system then you'd just need the panel # e82PR and branch connectors # e92PR to expand.
