Dual MPPTs work independently and allow unbalance input power. One string maximum input is up to 60% of Max. DC power. High efficiency and stable performance at entire input voltage and output power range. Max. Efficiency is up to 98.6%. Wide input voltage range gives more possibilities for accepting different string configuration and different type of PV modules. Bus capacitor adopts advanced film capacitor, designed with the latest thermal simulation technology for longer lifespan.
