Its MasterBus interface passes that data to compatible Mastervolt inverters, chargers and display units, forming the monitoring base of a MasterBus energy system.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShunt rating\u003c\/strong\u003e, 500A shunt resistor with integrated MasterBus interface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMonitoring\u003c\/strong\u003e, state of charge, voltage and current data\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNetwork sharing\u003c\/strong\u003e, shares battery data with connected Mastervolt MasterBus components\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e, suitable for any battery chemistry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eUsed as the monitoring foundation in off-grid solar, marine and vehicle energy systems. The shunt measures current flowing in and out of the battery bank so the MasterShunt can calculate state of charge over time, and that data is shared via MasterBus with compatible inverters and displays. Without a shunt, accurate SOC monitoring is not possible.\u003c\/p\u003e\u003ch3\u003eWhere it's fitted\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMastervolt 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\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFit the shunt in series with the negative battery conductor, then connect it to the MasterBus network using MasterBus cable.
