Product Description

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. A SHUNT is required, and which in some systems is already 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 TM2030 is easier for you to program the necessary system parameters.

  • The TM2030 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.

Main data functions:
push SELECT to cycle through these: Battery volts of main and secondary batteries:
Reads Battery volts 10.0-65.0V accurate to ± 0.2% ±1 least significant digit. For battery systems with nominal volts from 12 to 48V. Volts (only) can be read for optional second battery.

Battery amps (or watts) on main batteries:

You can choose to use either “amps” or “watts” to register the energy going in our out of the battery. Amps are accurate to ±1% ±1 least significant digit. Or the meter may be set up to measure only incoming energy from solar array or other energy source, or only load amps or watts if desired. Resolution and maximum amps depends on choice of required shunt. With the 100A/100 mV shunt: measures 0.01 to over 70 amps. With 500A/50mV shunt measures from 0.1 to over 400 amps. Speed of response: 1 second time constant.

Battery % full:

This number is based on net-amp hour reading divided by the user programmable value of battery capacity. This is more accurate than other methods which do not use amp-hours to compute battery energy content (for example less expensive monitors which rely only on battery voltage to estimate energy content). It shows a percentage from 0 to 100. The assumed BATTERY CAPACITY, upon which this display is based, can be programmed from 10-10,000 amp-hours.

Display off:

The display may be turned off (to darken display and for lowest current draw of 16 milliamps.)

Amp Hours from “full”: Shows actual “net” amp-hours removed from the battery from ±0.01 to±80,000 amp-hours. A flashing decimal point reminds you to multiply the reading by 1000 when the Amp-hour number exceeds 999. It is also possible for this display to measure only total amp-hours produced by an energy source, such as solar array, or
only load amp-hours, by wiring the shunt in the desired current path.

Days ago since batteries were last fully charged:
To prolong their life, lead-acid batteries shouldn’t go too long between being fully charged. This display will show you how long since they last received a full charge—measures from 0.01 day to over 600 days. If desired a “battery reminders” lamp will flash to alert the user when this number exceeds a value programmable by user from 1 to 60 days.

How many days ago since the battery was equalized:
It is often recommended that “wet cell” lead acid batteries should be periodically given an overcharge, called “equalization,” to maintain their capacity. This is typically done every month or two. It’s easy to forget how many days since they were last equalized—this timer will keep track for you. You will need to reset this number manually whenever you equalize the batteries.
If desired the “battery reminders” lamp will alert you when this number exceeds a user adjustable “maximum equalize time” from 1-250 days.

Watts or Amps:
This “extra data” display shows whichever one was not chosen for the “main data”.

A proven measurement circuit with added features. The TriMetric measurement circuit has proven accurate and reliable for over a decade. Newer features include improved lightning protection, easier programming, some data logging and measurement of watts. All programmed information retained when meter unpowered.

Now choose three levels of operation.
Defaults to Level 1 for most users to keep operation simple. Level 2 and 3 add logged data and additional flexibility for more technical users.
May be located up to 100 feet (30 m) from batteries.
Connect with four AWG 22 (.644 mm2) wires. Up to 300 feet (90 m) with AWG 18 (.823 mm2) wire. Longer distances are possible with larger wire size.
Bright display with low current draw.
Requires about 30 milliamps with display on—about 16 milliamps with display off.

Battery system size:
For 12-48V nominal system voltages. Battery system size: 10 to
10,000 amp hours.
Serial Data Output: Technical users can access all
real time data via serial data output
