SGC-1 MPPT Solar Charge Controller
Overview
The SGC-1 is a 12/24V 40A step-down Maximum Power Point Tracking (MPPT) solar charge controller. The MPPT system means the SGC-1 can deliver up to 30% more power from the solar panels to the battery by operating the panels at their most efficient operating point.
The SGC-1 is microprocessor controlled and includes extensive fault protection. Multiple SGC-1 units can be connected in parallel to support larger loads.
The SCG-1 is convection cooled eliminating the power load and noise of a cooling fan.
