Battery Monitoring Systems

NEW!

PentaMetric System Monitor

369-009 Pentametric Input Unit $199

369-010 Pentametric Display Unit $179

369-011 P-M Computer Interface $89

The PentaMetric System monitor has the capability of working on 12V to 48V systems with the ability to measure current from three sources (shunts). It measures volts, amps, amp-hours, watts, watt-hours, temperature and battery % full. It also can perform data logging functions and output the data to a spreadsheet. Amp hours, Watt hours, Temp.max/min, Volts, Amps and Battery % full can be recorded from once a day up to once a minute. Also included is a battery voltage triggered relay (up to 1A) and audible and visual alarms.

The PentaMetric System consists of three major components: an Input unit, a Display unit and a computer RS232 Interface unit. For USB operation an RS232 to USB adapter would be required. Software for Windows is provided. The Input works with either the Display, the RS232 Interface or both. A rather extensive set of installation instructions is provided with the System and both the software and Instructions are kept up-to-date on the Bogart Engineering website (www.bogartengineering.com).

This is now the System Monitor to get for anyone wanting to achieve complete monitoring and control of and stand-alone alternative energy system.

Trace TM 500 System Monitor TM 500

741-001	TM 500 System Monitor	$245
741-002	TM 500 NS System Monitor	$195
741-005	48 Volt Adapter	$40

The TM 500 and TM 500 NS are multi-function monitors that also act as a "gas-gage" for your system. They measure system voltage, current, collective amp-hours (amp-hours in minus amp-hours out), as well as a number of other system parameters. This monitor is based on the Tri-Met meter listed on the previous page and has most of the same functions.

The TM 500 comes complete with a 500A shunt while you have to supply your own for the TM 500 NS. Included with both units is a 50' shunt cable and a small power supply board which allows easy attachment of the shunt cable to the shunt and battery positive power. This is a very easy unit to install.

Brand Electronics Power Meter

369-120 Model 4-1850 $149.95

The Brand Model 4-1850 power meter is both accurate and reliable. It is designed for the energy conscious home owner who wants to know how much power their equipment and appliances are using and how much it costs to operate them.

For the alternative energy user, the 4-1850 is a great device for understanding where all those solar watts are going. It will work just fine when used to measure devices hooked up to a modified sine wave inverter. Of course it works on devices powered by a sine wave inverter as well.

The Brand power meter can measure devices requiring up to 1850 watts. It keeps track of kilowatt-hours, average monthly cost, and instantaneous watts being used. For arriving at an average monthly cost figure, you must enter in your cost per kilowatt-hour.

This is an invaluable meter for anyone interested in knowing just how much power they use through their homes.

Sears Craftsman Digital Multimeter Sears DVM (DSCN1398)

369-003 $40

The Sears 82040 features all the major functions—AC and DC volts, Ohms and Amps - including a 20A range. The 20A range allows you to test short circuit current of a module or small array. All functions feature auto-ranging operation. The meter includes a plastic protective holster, test leads and is powered by two 'AA' batteries which we include. We highly recommend owning a digital multimeter even though you may have other system monitoring devices. It allows you to check the voltage of individual batteries in your bank and makes trouble-shooting your system a lot easier.
