General Information
Negative ground controller.
The Renogy Solar Suitcase combine highly efficient monocrystalline solar panels with a 20A
Voyager charge controller to create an easy-to-use, ‘plug and play’ system.
The alligator clips included in this package make it easy to connect the panel to a battery in
seconds. If one ever needs to connect a battery with a different type of end terminal, the
alligator clips are attached via MC4 Connectors.
This system is specifically designed for mobile off-grid applications, where space and weight
limitations are abundant. The Solar Suitcase models support 12V deep cycle battery varieties
such as sealed-lead acid, gel, and flooded. With built-in tilting stands, these panels can be
adjusted at different angles to maximize the power output throughout the seasons.

Convenient storage case for easy transportation.
PWM Technology
Key Features
The Voyager utilizes Pulse Width Modulation (PWM) technology for battery charging. Battery
charging is a current based process so controlling the current will control the battery voltage.
For the most accurate return of capacity, and for the prevention of excessive gassing pressure,
the battery is required to be controlled by specified voltage regulation set points for Absorption,
Float, and Equalization charging stages. The charge controller uses automatic duty cycle
conversion, creating pulses of current to charge the battery. The duty cycle is proportional to
the difference between the sensed battery voltage and the specified voltage regulation set
point. Once the battery reached the specified voltage range, pulse current charging mode
allows the battery to react and allows for an acceptable rate of charge for the battery level.
