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
Provides information you need to protect your battery investment:
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
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 HighDownload a PDF with more information on shunts here Download a PDF copy of the TriMetric Brochure here
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.
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
The 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:
There are 3 types of data logging function. With the computer interface, all 3 types can be output to a spreadsheet file
