BOGART ENGINEERING TRI-METRIC AMP-HOUR METER

This meter operates on 12, 24 or 48 VDC. LEDs show volts, amps, and amp-hours. Amp-hours can be displayed directly or as “% full.” One LED indicates charging and fully-charged states. Another LED indicates when charging or equalization is needed and warns of low battery-voltage events. The meters also record minimum and maximum voltage, days since last charge, days since last equalized, and total lifetime amp-hours withdrawn. The TriMetric can be located up to hundreds of feet away from batteries using inexpensive four-conductor twisted-pair meter wire. A shunt is required for operation. Use the 500 A shunt on a 12 VDC inverter larger than 800 W, or a 24 VDC inverter larger than 1,600 W. Use a 1,000 A, 100 mV shunt for systems with stacked inverters or where continuous current is over 300 A. The 1,000 A/100 mV shunt has the same resistance as the 500 A/50 mV shunt and may be used interchangeably. Order the shunt separately. These meters work with battery banks up to 2,500 Ah.
