Mastervolt MasterShunt 500 CZone

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

• Multi-network integration: MasterBus, CZone, and NMEA 2000 interfaces provide a single-point connection for battery data and enable data sharing with chargers, inverter/chargers, and displays.
• Accurate SOC & remaining runtime: Digital shunt delivers precise State of Charge and a realistic indication of remaining time, aiding proactive energy planning.
• Programmable automation: Built-in real-time clock and programmable events allow automation of actions such as generator start when battery is low or warnings at a chosen depth of discharge.
• Scalable current handling: Supports high-current configurations; multiple MasterShunt units can be installed in parallel to scale capacity as loads grow.
• MasterConnect integration: MasterConnect simplifies connections to the DC Distribution product, making setup straightforward and reliable.
• Fuse options: Includes an internal bus bar; Class T or ANL fuses can be ordered separately; you can choose fuse type, rating, and location to suit your installation.
• Rugged design: Rugged housing with isolated DC connections protects your system and ensures long-term reliability.
• Current handling: 300 A continuously, 400 A for 10 minutes, 500 A for 5 minutes, and 600 A for 2 minutes.
• Comprehensive monitoring: Tracks voltage, current, SOC, and remaining runtime, with data output to MasterBus, CZone, or NMEA 2000 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.
• Low idle consumption: Efficient operation with minimal parasitic draw when idle (23 mA in normal operation; <1 mA in power-saving mode).
• Compact footprint: Dimensions 5.9 x 5.9 x 2.6 inches; weight approximately 1.5 lb.

The MasterShunt 500 CZone gives you precise visibility into your battery bank and automates routine tasks to reduce manual intervention. With accurate SOC and realistic runtime estimates, you can plan charging, generator runs, and device usage more confidently. Its scalable current capacity means you can expand your system as loads grow, while MasterConnect and multi-network compatibility keep wiring simple and reliability high. This device acts as the core of your energy ecosystem, supporting longer battery life and smarter energy management across 12/24 V systems (and higher voltages where supported).
