Standard off-grid 12/24V solar panels with high voltage or multiple panels with voltage up to 100V can be used with the Rover MPPT charge controller. Moreover, the maximum combined solar power input for a system using 12V batteries is 400W, and for a system using 24V batteries, it is 80W. This controller, in particular, will greatly boost a solar system's efficiency when the voltage of the solar panels is substantially higher than the voltage of the batteries.
