Unlike standard standalone monitors that only display basic metrics on a local screen, this intelligent shunt acts as the central information hub for your energy storage system. By measuring voltage, current, state of charge (SOC), and time remaining with exceptional accuracy, it provides the critical data needed to manage power consumption and protect your battery investment.\u003c\/p\u003e\u003cp\u003eEngineered for demanding marine, mobile, and off-grid industrial applications, the MasterShunt 500 seamlessly shares real-time battery data across your entire electrical network. This allows connected battery chargers, inverter\/chargers, and multifunction displays to adjust their operation dynamically based on the exact state of your battery bank, reducing the risk of premature battery degradation or unexpected power loss.\u003c\/p\u003e\u003ch3\u003eUnmatched System Integration and Automation\u003c\/h3\u003e\u003cp\u003eEquipped with native support for \u003cstrong\u003eMasterBus, CZone, and NMEA 2000\u003c\/strong\u003e communication protocols, this unit eliminates the need for complex bridging hardware. You can monitor your battery bank directly from compatible marine chartplotters, CZone touchscreens, or Mastervolt displays. Furthermore, the built-in real-time clock and programmable event architecture allow you to automate your power system. You can configure the shunt to automatically start a backup generator when the state of charge drops below a specific threshold, or trigger high-priority alarms at a designated depth of discharge.\u003c\/p\u003e\u003ch3\u003eFlexible Fuse Configuration and Serviceability\u003c\/h3\u003e\u003cp\u003eThis specific variant (SKU: MV-77020115) is supplied in a \u003cstrong\u003eno-fuse configuration\u003c\/strong\u003e, featuring a heavy-duty internal busbar installed out of the box. This provides system designers with the flexibility to utilise external circuit protection or install a specific main fuse directly into the unit. The internal busbar can be easily replaced with either an \u003cstrong\u003eANL fuse or a Class T fuse\u003c\/strong\u003e (ordered separately), saving valuable installation space and reducing cable connections by combining your primary battery fuse and shunt into a single footprint.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComprehensive Telemetry:\u003c\/strong\u003e Accurately tracks battery voltage, current draw, state of charge (SOC), and estimated runtime remaining.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Network Compatibility:\u003c\/strong\u003e Integrates directly with MasterBus, CZone, and NMEA 2000 networks for system-wide data sharing and display integration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntelligent Automation:\u003c\/strong\u003e Features programmable system events and an internal real-time clock to automate generator starts, load shedding, or low-voltage warnings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance Service Mode:\u003c\/strong\u003e Prevents the loss of historical battery data and system memory when power is disconnected during routine battery maintenance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustomisable Circuit Protection:\u003c\/strong\u003e Supplied with an internal solid busbar that can be swapped out for a high-interrupt Class T or ANL main fuse (fuses sold separately).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScalable Architecture:\u003c\/strong\u003e Supports parallel installation of multiple MasterShunt units for high-capacity systems requiring higher current ratings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafe and Modular Design:\u003c\/strong\u003e Built with a ventilated housing, transparent terminal isolation covers, and MasterConnect compatibility for streamlined connection to Mastervolt DC Distribution systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eEngineered for Reliability and Safety\u003c\/h3\u003e\u003cp\u003eHigh-current DC systems require robust physical protection and secure connections. The MasterShunt 500 features a durable, ventilated housing designed for efficient heat dissipation under heavy loads. Clear protective covers isolate the high-current DC connection terminals to prevent accidental short circuits in tight electrical lockers. For larger vessels or expansive off-grid setups with massive inverter loads, multiple MasterShunt 500 units can be installed in parallel to increase the overall current handling capacity without sacrificing monitoring accuracy.\u003c\/p\u003e\u003ch3\u003eUpgrade Your Power Management System\u003c\/h3\u003e\u003cp\u003eEquip your vessel, off-grid cabin, or specialized vehicle with the Mastervolt MasterShunt 500 for accurate telemetry and automated system protection.
