The Cascadia 4x4 VSS System™ hard-mounts to the hood of your Jeep and, during daylight hours, provides a constant flow of clean solar energy to your primary or secondary vehicle batteries. This gives you the ability to run 12V accessories like fridges, phone/laptop chargers, lights, power inverters etc. without the need to start your engine and without the fear of draining your battery and leaving you stranded. The VSS System™ is completely plug-and-play if paired with our optional MPPT solar charge controller and can be installed in as little as 1.5 hours.
