New for April 2014 is the TriMetric TM-2030 by Bogart Engineering. Very similar to the TM-2025, but can now work in tandem with their new SC-2030 controller for optimized battery life, capacity use and efficiency. Can also be used as a stand-alone monitor.

TriMetric TM-2030 is available in two models:TM-2030-RV and TM-2030-A. The older models (TM-2025 and TM-2020) are still supported and available by special order.

The TriMetric is used to monitor battery systems used in remote homes, RVs or boats that have batteries that store solar, wind, or possibly generator powered chargers. They will help you maintain your batteries. All for under $200 with a “shunt” (which is required but not included, see SH-500-50 or SH-100-100). Some systems may already have a Shunt installed.

All models are designed to monitor the following:

  • “Percent Full” (“State of charge”) of your batteries, so you can see if you need to charge them more, or check that overall usage is less than your charging resources.
  • Volts of the batteries, for example to check that they are being charged at proper voltage.
  • Energy going in, or out of your batteries, measured in amps or watts, so you can see that your charging sources are charging properly, or how much current your loads are using.
  • How many days since the batteries were fully charged: to remind you to not wait too long between fully charging your batteries to maximize their life.
  • The TM-2030 is easier for you to program the necessary system parameters:

  • The TM-2030 has some minimal data logging, which can be useful for a technician to diagnose some common setup or operational problems with battery systems.
  • The TM-2030 will operate with (nominal) battery systems from 12 to 48V. The TM-2020 will operate with 12 or 24 V systems, but requires the addition of the “TM-48VA” Adapter and lightning protection board when using it with 48V battery systems. This also provides lightning protection for the TM-2020.
  • The TM-2030 can also monitor the voltage only of a second battery, such as a starting battery, or possibly also the input voltage of a solar array (if less than 100 volts.)
  • The TM-2030 has a “simplified” level of operation suitable for most users, but can be configured for more flexibility (and complexity) where occasionally required.
  • (For the technically knowledgeable only) The TM-2030 has a serial data output of all the “real time” data—which could be used to access data for other control or output in, for example OEM applications.
  • The newer TM-2030 includes better lightning protection compared with the TM-2020.
  • It is easier to view and enter programmed parameters.
  • This is for the TM-2030-RV-F.

    Includes enclosure.

    Includes Fuse and Fuse Holder. Contact us if you wish to special order without the Fuse and Fuse Holder (TM-2030-RV).

    Does not include a Shunt. A Shunt is required. See SH-500-50 Shunt for most loads (70+Amps), measuring down to 0.1 amps. SH-100-100 Shunt is typically only used with amperage loads under 70 Amps and where need to measure down to 0.01 amps.
