A Battery Monitor will help you manage your power usage and achieve maximum battery life,
by letting you know how much power you have available to use.
It is recommended that you have a Battery Monitor for your batteries to ensure that you do
not take out more than you should from their capacity, and by doing
 this ensuring that your batteries have a much longer life span.

We have the following models of Bogart Battery Monitors:-


TriMetric TM2020 Battery Monitor

TriMetric TM2025 Battery Monitor

PentaMetric PM100-D Battery Monitor
PentaMetric PM100-C Computer Interface
PentaMetric PM5000-U Input Unit

TRIMETRIC TM2020 BATTERY MONITOR


Measures Battery Volts, Amps, Amp-Hours, Battery Percent Full, and Five Other Data Functions.



If your Home, Motorhome or Boat depends on batteries for electrical power, here's why a
Battery System Monitor should be part of your electrical system!

     Helps save valuable energy by letting you see how much you're using:
  • Use Amps to educate users about how much energy different electrical loads draw
  • Check that all loads are really off when you think they're off
  • Check for Phantom Loads - small loads that steal power 24 hours a day
  • Keep informed about how much energy you have left in your battery system
  • Reduce generator usage by knowing when you can efficiently shut off because batteries are approaching full charge
    
     Provides information you need to protect your battery investment:
  • Know when to turn on your generator to avoid damage from over discharging
  • Check that charging systems are charging to correct voltages for longest life
  • Be reminded not to let batteries go too many days between a full charge

     Helps locate system problems when they occur:
  • Monitor Solar arrays and Inverter/Chargers to be sure they are still charging at proper rates and voltage
  • Find out if batteries are still holding energy properly
  • Even if you're not an expert, a dealer or other knowledgeable person can more easily help you over the phone to locate a problem if you have a monitor on your system

Other Information and Features

    
How the TriMetric determines that Batteries are charged:
     When the TriMetric senses that batteries are charged, it resets the "days since charged" display to 0.00 and (at user
     option) resets the "Amp Hours" to 0.00 and the "Battery % Full" to 100%. The TriMetric determines that the batteries are
     "charged" when the battery voltage rises above a user programmed "charge voltage" (adjustable from 10.0 - 35.0 volts
     within 0.1 volt increments) and the charging amps goes below a user programmable "charge current criteria"
     (adjustable from 1 - 100 amps within 1 amp). This conditions must remain for 20 seconds for the values to reset to the
     charged state

    
User selectable efficiency factor:
     Amp Hours may be monitored without an "efficiency factor", meaning that the "charge" and "discharge" current for the
     "net Amp Hours" reading are both calculated at exactly 100% rate. Or a "charge efficiency" factor may be manually set
     from 60% to 100% in 1% increments. This means that the discharging current will subtract from Amp Hours at 100% rate,
     where as the charging current calculates at the lower specified rate, to approximate the "charge efficiency" of the
     battery. This compensates for the fact that you don't get quite as much charge out of a battery as you put in

    
The Same Reliable, Proven Measurement Circuit:
     This TriMetric circuit has proven accurate and reliable for over four years in production. All programmed information 
     retained when the meter is unpowered

    
Remote Locatable:
     Can be located up to 55 feet with four 22 AWG wires, and up to 150 feet with 18 AWG wire. Longer distances are
     possible with larger size

    
Bright Display with Low Current draw:
     Requires about 30mA with display on and about 16mA with display off

    
Size:
     Designed to fit into a standard "double-gang" electrical box mounted 90 degrees from the usual position.
     Panel size: 114mm Wide x 121mm High x 44mm Deep


Battery Monitor Accessories

     48 Volt Adapter / Lightning Protector (TM-48VA):
     This adapter allows the TriMetric meter to operate with 48 Volt Systems, and also provides lightning protection for
     12- 48 Volt Systems. It mounts next to the TriMetric terminal block and fits within the box

    
Choice of Two Shunts for use with TriMetric Battery Monitors:
     These are required for making the "Amps" and Amp Hour measurement as shown in diagram below

    
500 A - 50 mV Shunt:
     For systems with maximum current 400 amps continuous with no overloads, or 300 amps continuous with up to 5 minute
     overloads to 500 amps max. It allows amp readings as low as 0.1 amps. They are suitable for virtually all systems with
     moderate or large sized inverters.
     Size: 82mm Long x 44mm Wide x 48mm High

    
100 A - 100 mV Shunt:
     For systems with maximum current 75 amps continuous with no overloads, or 50 amps continuous with overload to 100
     amps or 8 seconds max. These are suitable for small systems, or for most applications where you want to measure only
     solar or wind input current. It allows amp readings as low as 0.01 amps
     Size: 50mm Long x 31mm Wide x 44mm High







TRIMETRIC TM2025-RV / TM2025-A BATTERY MONITOR


We have teamed up with Bogart Engineering to provide a better Battery Monitor.
A smaller design with the same great features as the original TriMetric TM2020, the
TM2025 now comes with a second battery bank voltage monitor, 12 / 24 / 48 VDC operation,
built-in lightning protection and a 100 or 500 Amp shunt.
TM2025-RV (Surface Mount) Dimensions (unit face): 75mm Wide x 133mm (108mm) High x 35mm Deep
TM2025-A (Panel Mount) Dimensions 112mm Wide x 120mm High (Panel hole 65mm W x 95mm H)

TM2025-A Panel Mount Meter

     The TM 2025 is intended to help maintain battery systems for nominal 12V to 48V systems, such as ones found in
     Homes, Motorhomes or Boats - which are regularly charged and discharged and use Deep Cycle batteries
    
     The "Amps" or "Watts" display measures the energy going in or out of your batteries so you can check you charging
     systems, and also to see how much energy each of you appliances use to help you conserve energy
    
     The "% Full" display will help you keep track of how charged or discharged you batteries are

     The "Volts" display will let you discover if your charger systems are charging to the proper voltage, neither too high or
     too low, which is important for maximising your battery life. Also, when battery voltage gets too low, you will know you
     battery is getting really close to being discharged

     The "Days Since Charged" display shows how recently the main battery system was fully charged, so if it hasn't been
     charged recently you can perform extra charging if necessary to help maintain the capacity of your batteries

     The TM 2025 can also measure "Voltage Only" of a second battery set, such as the motor starting battery, or solar
     voltage input to an MPPT charge controller

    
Data Logging:
     Not everyone will use the data logging information, which records daily maximum battery voltage level, and minimum
     charging amps to check for proper charging levels for the last 5 days. In addition, for up to five of the most recent
     charge/discharge cycles if also logs Cycle Length, Charge Efficiency, Minimum Battery % Full and Minimum Voltage
     Level for each cycle

     This is useful diagnostic information which a technician can use to determine that the whole system is working properly

    
Serial Data Output:
     For extreme techies only: The TM 2025 also has a serial 0- 5V output with streaming, real time, serial (ASCII) data
     that could be used to control other electronics





PENTAMETRIC BATTERY MONITOR


The new PentaMetric Battery Monitor system offers a lot more capability than the TriMetric monitor
It measures 1 or 2 battery systems with a common negative
With one battery system, battery current plus two charging sources/loads can be measured



    
The PentaMetric System consists of these components:
     PM-5000U   Data input unit to collect, process and log data (near batteries)
     PM-100D     Optional readout unit (shown above) with 2 line LCD display and control buttons
                           This connects to input unit with 4 wire cable up to 1000 feet away
     PM-100C     Optional computer interface with software to control and read out all data (RS232)
                           Data may be accessed and controlled using either (or both) the optional LCD or the computer interface


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) 0.01-200 Amps (with 100A/100mV shunt) or 0.1-1000 Amps (with 500A/5mV 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. In addition, one charging source
     could be separately monitored
     Temperature: -20 to +65 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) 0.01-200 Amps (100A/100mV
     shunt) or 0.1-1000 Amps (500A/50mV shunt)
     For example: this can be used to show a more accurate 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 the "alarm" and relay functions, so very short term anomalies will be ignored
     Watts: (2 channels) 0.1-20,000 watts
     Watt - hours: (2 channels) 21,000 kilowatt hours
     Battery % Full: (2 channels) 0-100%
     Days since batteries charged: (2 channels) 0.01-250 days
     Days since batteries equalised: (2 channels) 0.01-250 days


    
Data logging functions:
     There are 3 types of data logging function. With the computer interface, all 3 types can be outputted to a 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)
               -   Battery % 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:
     Controls 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 Equalised
