The C-BOX is a comprehensive energy and lighting management system designed for full control and monitoring of onboard electrical installations. It enables real-time supervision of battery state of charge, energy consumption, solar production, generator and shore power input, as well as tank levels and temperature. It integrates CAN-Bus, Ethernet, WiFi, and CRISTEC Connect connectivity, providing remote access, cloud data logging, and configuration via mobile devices or the optional touchscreen display. In addition, it allows control of up to 128 lighting points or zones (RGBW, LED, underwater lighting) and manages programmable relays for automation functions such as generator start/stop or alarm control.
