Meet the Mastervolt MasterShunt 500 CZone — the intelligent digital shunt that becomes the heartbeat of any battery-powered energy system. Seamlessly integrated with MasterBus, CZone, and NMEA 2000 networks, it brings you comprehensive monitoring, automation, and reliable SOC accuracy in one robust package.

The MasterShunt 500 CZone fits right into a CZone system with included setup tools and configuration file, delivering a single-point connection for all your battery data. It shares information with other MasterBus, CZone, or NMEA 2000 devices such as battery chargers, inverter/chargers, and displays, enabling complete automation and a cohesive energy ecosystem.

Key features and benefits

• Highly accurate SOC and time-to-empty — digital shunt delivers precise State of Charge and a realistic indication of the time remaining, helping you plan ahead with confidence.
• Programmable automation — built-in real-time clock and programmable events let you automate critical actions, such as starting a generator when the battery is low or issuing warnings at a chosen depth of discharge.
• Flexible current handling — supports high-current configurations; for higher loads, multiple MasterShunt units can be installed in parallel to scale up capacity.
• Easy integration with MasterConnect — MasterConnect system simplifies connections to the DC Distribution product, making setup straightforward and reliable.
• Freedom of fuse choice — choose the fuse type, rating, and location to suit your installation; the MasterShunt includes an internal bus bar, with Class T or ANL fuses available to order separately.
• Robust, safe design — a rugged housing with isolated DC connections protects your system and ensures long-term reliability.
• Comprehensive monitoring — tracks voltage, current, SOC, and remaining runtime, all output to your MasterBus, CZone, or NMEA 2000 network via a single cable.
• Versatile power ranges — supports 12 and 24 V DC, with 36 and 48 V DC supported from hardware version K of the MasterShunt 500.
• Built for the heart of your system — designed to be the core of every battery-powered energy setup, sharing essential data to optimize charging, inverters, and displays for better performance and longer battery life.
• Low idle consumption — efficient operation with minimal parasitic draw when idle.

The MasterShunt 500 CZone is the proven choice for precise battery monitoring, automation, and system control. It provides all the data you need to monitor your battery bank and control your system effectively, while enabling advanced automation and seamless communication across your MasterBus, CZone, and NMEA 2000 devices.
