Charge Control Unit (CCU)

The Charge Control Unit is engineered to manage wide line fluctuations and extreme climatic conditions in rural and semi-urban telecom deployments, with operation up to +70°C. It is built as a hybrid MPPT plus SMPS system with rectifier and MPPT modules, single-phase AC input, and four-channel solar input in a hot-pluggable, fan-cooled configuration. Designed for standalone use or parallel operation within a digitally controlled DC power system, the CCU delivers constant output power of 15,000 W, or 300 A at 50 V, across the 48 to 58 Vdc range, with CAN bus communication between modules and controller. The compact system accommodates 6+1 rectifiers and 4 MPPT modules in a small footprint.
