TriMetric Meter TM-2020

The TriMetric battery monitor is designed to assist in battery care, power conservation and system maintenance with system voltages of 12, 24, or 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. Reliability, accuracy and simplicity are key product objectives. The TriMetric requires an external shunt located near the batteries, usually in line with the inverter negative cable, to measure amps and amp-hours. The meter may be located hundreds of feet away from batteries and is connected to the shunt with a 4 wire cable (power, signal, ground 1 and ground 2).
To really know how much power you're using and how much you're putting back into your batteries you need a meter like this. To see with a quick glance at the meter the percentage of power left in your batteries is incredibly useful. To see how many amp hours a day you are using can help you determine where to conserve power if needed. There are other meters out there that do much more than the Tri-Metric but at MSRP of under $200 with a shunt you can't go wrong with the Tri-Metric from Bogart Engineering.
