Pentametric battery monitor

Bogart Engineering Pentametric Battery Monitor

The Pentametric Battery Monitor measures up to 2 separate battery systems with a common negative. With one battery system, meter monitors battery current plus two charging sources/loads. The complete system consists of an input unit placed near the batteries, a display unit that can be placed up to 1,000' from the battery bank, and computer interface unit. It can monitor up to 3 shunts: For example, measure total solar input and wind input independently in addition to monitoring battery "state of charge." Audible and visual alarms warn of high and low battery conditions. An optional Windows software interface allows control of and access to all data from the computer. A relay output allows control of a generator or external alarm. 2-year warranty.


Basic measurements:

  • 2 voltage channels: 8-100 VDC
  • 3 amperage channels
    - 200 ± .01 A w/ 100A/100mV shunt
    - 1000 ± 0.1 A w/ 500A/50mV or 1000A/10mV shunt
  • Temperature -20°C to +65°C

Secondary measurements:

  • Amp-hour (3 channels): to ±83,000 amp-hours
  • Cumulative (negative) battery amp-hours (2 channels)
  • Smoothed (time filtered) amps
  • Volts (2 channels): 0-100 volts
  • Watts (2 channels) ±.01- 20,000 watts
  • Watt-hours (2 channels) ±21,000 kilowatt hours
  • Battery % full (2 channels) 0-100%
  • Days since batteries charged (2 channels) .01-250 days
  • Days since batteries equalized (2 channels) .01-250 days

Data logging functions

The Pentametric Vattery Monitor has 3 data logging modes that can run simultaneously. With the computer interface, all 3 tyes can be output to a spreadsheet file. Periodically Logged Data mode records amp-hours (3 channels), watt hours (2 channels), Temperature max/min (1 channel), volts (1 channel), amps (1 channel) at regular intervals (once per day to once per minute). Battery Discharge Voltage Profile mode logs volts and amps every time the charge level changes by 5% (or 10%) for 1 or 2 battery systems. Battery Cycle Efficiency mode documents system efficiency for up to 2 battery systems.
