Mastervolt 77020115 – MasterShunt 500 with CZone Battery Monitor
The Mastervolt MasterShunt 500 with CZone is the core component of intelligent DC energy systems. As a digital battery monitor and shunt, it collects and communicates precise battery data including voltage, current, state of charge (SOC), and estimated time remaining. Supporting MasterBus, CZone, and NMEA 2000 protocols, the MasterShunt acts as a central control and automation point, enabling alarms, logging, auto generator start/stop, and programmable event management. Designed for 12/24 V systems (and 36/48 V with hardware version K), it features smart fuse integration and is scalable for high-current or parallel setups.
Key Features:
- Compatible with MasterBus, CZone, and NMEA 2000 systems
- Digital shunt with extremely accurate SOC and current measurement
- Supports generator automation, timers, and alarms
- Logs system performance and battery history
- Precise estimation of runtime based on actual load and capacity
- Supports parallel use of multiple MasterShunt units for higher current
- Service mode preserves memory during maintenance
- Flexible fuse options: internal busbar or ANL/Class T fuse support
- Robust housing and insulated DC terminals
- Supplied with temperature sensor, DC cap, terminator, and drop cable
