The TriMetric Battery Monitor
The TriMetric battery monitor is designed to assist in
battery care, conservation and system maintenance of battery powered
systems that use storage batteries with system voltage from 12-48 volts.
It provides the user with information on battery "volts",
"amps" and "amp-hours" and "battery percent full"
information, based on measuring the amp-hours removed from the battery
system. Reliability, accuracy and simplicity are key product objectives.
The TriMetric requires an external shunt
located near the batteries to measure "amps" and
"amp-hours". The meter readout may be located hundreds of feet
away from batteries and is usually connected to the shunt with a 4 wire
cable. “Suggested retail” price is $169, not including the “double
gang” electrical box shown above, or necessary shunt. Cost with these
will be less than $200.

shunts--For example: measure total solar input and wind input
independently in addition to monitoring battery "state of charge"
- Access the data with
display unit (shown above) with LCD display and buttons up to 1000
feet from batteries.
- Optional computer
interface with (Windows) software to control and read out all data.
