The Xantrex TM500A system meter is THE meter for your solar electric system. This is the Trimetric Meter manufactured for Xantrex in a special package with fuse and fuse holder.

The TM500A trimetric meter 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.

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 Deltek 50 mV/500 amp shunt, a prewired cable, and a plug-in adapter board.
