The MasterBus interface allows it to share battery data with compatible Mastervolt inverters, chargers, and monitoring screens, forming the monitoring foundation of a Mastervolt energy system.\u003c\/p\u003e\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e500A shunt resistor with integrated MasterBus interface\u003c\/li\u003e\n\u003cli\u003eAccurate state of charge, voltage, and current monitoring\u003c\/li\u003e\n\u003cli\u003eShares battery data with all connected Mastervolt MasterBus components\u003c\/li\u003e\n\u003cli\u003eSuitable for any battery chemistry\u003c\/li\u003e\n\u003cli\u003eEssential component for off-grid, marine, and vehicle energy systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\u003cp\u003eThe shunt measures current flow in and out of the battery bank, allowing the MasterShunt to calculate accurate state of charge over time. This data is transmitted via MasterBus to compatible Mastervolt inverters and display units, providing a clear picture of available energy and system performance. Without a shunt, accurate SOC monitoring is not possible.\u003c\/p\u003e\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBattery monitoring in Mastervolt off-grid solar systems\u003c\/li\u003e\n\u003cli\u003eMarine and yacht energy management\u003c\/li\u003e\n\u003cli\u003eMotorhome and vehicle battery monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\u003cp\u003eInstall the shunt in series with the negative battery conductor. Connect to MasterBus network using MasterBus cable. All wiring must be carried out by a qualified electrician or marine electrical engineer.
