The 4th generation of drivetek’s well-proven MPPT-Race. Optimized for solar boot applications with a low input voltage range (< 60V). The
absence of almost any switching losses makes this converter ideal for solar cars and any solar power application which needs extremely
high efficiency over a wide power range. Current and voltage limits are customized to increase accuracy of MPPT algorithm. High
efficiency allows an operation temperature range up to +70°C.
