The CCU system is designed as a hybrid type with MPPT + SMPS system based on rectifier & MPPT modules with high efficacy, single phase AC input & 4-channel solar input hot-pluggable, fan-cooled MPPT, rectifier, and battery charger for stand-alone use or for working in parallel as part of a DC power system equipped with advanced digital controller. The constant output power (15000W i.e. 300A at 50V) characteristic supplies the specified power over the full output voltage range (48 to 58Vdc). There is a digital communication (CAN bus) between modules and the controller. The compact system has 6+1 rectifiers & 4 MPPT accommodated in a small footprint. It also showcases an Optimal Power Performance resulting in high efficiency and precision.
