PentaMetric Battery Monitoring System
Input Unit
PM-5000-U

The PentaMetric Battery Monitoring System consists of 3 Possible Components (each ordered separately):

Please Note: Data may be simultaneously accessed and controlled using the Display Unit and/or any one of the three computer interface options.

The new PentaMetric battery monitor system offers a lot more capability than the TriMetric monitor. The PentaMetric would be the choice for doing system data analysis utilizing a computer.

Features

  • It measures 1 or 2 battery systems with a common negative.
  • With one battery system, battery current plus two charging current sources can be separately measured. Two voltages can be measured. Watts, watt hours and amp hours are also measured.
  • It has a optional computer interface with (Windows) software that can control and read data on a local computer, or also over the internet.
  • It can log data that can be imported to a spreadsheet and graphed to analyze performance and diagnose system problems. System efficiency (ratio of amp hours charged to amp hours discharged for each charge cycle) is regularly logged.
  • Monitor up to 3 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) with LCD display and buttons up to 1000 feet from batteries.
  • Relay output to control generator or external alarm
  • Audible and visual alarms for high and low battery conditions

Real Time Measurement Capability

Basic measurements:

Volts: (2 channels) 8-100 volts. For example you can monitor volts from two battery systems. Or battery voltage, plus the solar array voltage if you have a peak power point tracking controller.
Amps: (3 channels) ±.01-200 Amps (with 100A/100mV shunt).± 0.1-1000 Amps (with 500A/50mV shunt) Each of these requires a separate shunt. There are many different ways these can be used. For example one channel can be used to keep track of battery system energy content and the two remaining ones can be used for separate measurement of two charging sources, such as total solar or wind production. Or two battery systems can be separately monitored if they share a common negative connection--and in addition one charging source could be separately monitored.
Temperature: -20 to +65 degrees C.

Secondary measurements derived from basic measurements:

Amp hour: (3 channels) to ±83,000 Amp-hours
Cumulative (negative) battery amp hours:(2 channels) to -1,000,000 amp-hours
This measures accumulated amp hours (usually from a battery) only when the amps value is negative. Its purpose is to measure the total cumulative 'wear' of batteries during their lifetime.
Smoothed (time filtered) Amps:with time constants of 0.5, 2 or 8 minutes (3 channels) ±.01-200 Amps (100A/100mV shunt).± 0.1-1000 Amps (500A/50mV shunt)
For example, this can be used to show a more accurage estimate of wind charging input when the wind source is varying in speed.
Smoothed (time filtered) Volts:(2 channels) 0-100 Volts. The smoothed values for both Amps and Volts are used for triggering "alarm" and relay functions so very short term anomolies will be ignored.
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

There are 3 types of data logging functions. With the computer interface all 3 types can be output to spreadsheet file.

  1. "Periodically logged data" can record any or all of the following at regular intervals: once per day to up to once per minute
    • Amp hours (3 channels)
    • Watt hours (2 channels)
    • Temperature max/min (1 channel)
    • Volts (2 channels)
    • Amps (1 channel)
    • Batt%Full (2 channels)

  2. "Battery discharge voltage profile" data logs volts and amps every time charge level changes by 5% (or 10%) for 1 or 2 battery systems. This checks that battery capacity is still OK--by observing that battery voltage does not decline excessively as charge level drops.

  3. "Battery cycle efficiency data" documents system efficiency for up to 2 battery systems. For each 'charge/discharge' cycle it records: cycle length (hours), total amp hours charged, total amp hours discharged, computed average 'self discharge' current and charge (amp hour) efficiency.

Controls and alarms

Relay output: Control external relay to go on and off at specified voltage levels and/or battery state of charge levels. "On" and "Off" levels can be independently set.

Audible and visual alarms

Has audible or visual signal for 'Low voltage or low state of charge', 'High voltage', 'battery is charged', 'too many days since charged', and 'too many days since equalized'.

Warranty: The Bogart Engineering warranty policy is to repair at no cost any of their products that develop a problem not due to customer misuse.

Good design, seems to do its job

I have the pentametric paired with the Ethernet unit on my small (125 watt) off grid system. For starters, Id like to compliment bogart for making it here in the US. Thats actually one of the reasons I chose it over the Xantrex link pro line. Wiring it up took a while because of how advanced th...

I purchaesed the PentaMetric input unit and the computer interface unit. I am using the USB port. The computer inerface unit uses the RS232 port. This required me to buy an RS232 to USB converter at Radio Shack. Since I am using the USB port, I down loaded the PMcomm77 software. It worked but the...

I purchased all three parts to this meter, and it works great. I'm looking forward to installing my micro-hydro system in the spring so it can monitor it as well.
I've set the relay up to automatically start my generator, a great addition, works great.
Not sure why the computer ...
