Xantrex TM-500A with Shunt

Measure current, amp-hrs, and battery voltage levels.

The TM500A provides easy to understand information such as produced and used DC current. It keeps track of the energy your system has available and energy consumed to ensure adequate reserve power capacity and longevity of your battery bank.

The TM500A is both an energy supply "fuel gauge" and a sophisticated user-option "energy storage computer" that records system characteristics and data. It provides data on all critical system functions, and is capable of monitoring total accumulated charge power from sources such as photovotaic arrays, wind power systems, and generator sets. The TM500A comes with 50' (15 m) of cable, a 50 mV/500 amp shunt, a prewired cable, and a plug-in adapter board.

The TM500A measures and records the following:

Battery Voltage: 8 to 32 VDC or to 70 Volts DC with optional 48 VDC adapter
Net Battery Current: 0.1 to 999 Amps DC
Battery Charge Level: 5% increments
Cumulative Amp Hours: Monitors battery bank use and provides estimated battery life information
Days since Full: Days since the battery bank was fully charged -- encourages proper battery management by indicating system problems
Battery Highest Voltage: Resetable, monitors charge controllers and battery chargers
Battery Lowest Voltage: Resetable, monitors system to detect malfunction or system failure.
 Use the 48-volt adapter for 48-volt systems.

Dimensions: 4.55" x 4.55" x 1.725". 2-year warranty.
