But the 100A/100mV shunt will allow you to see on the meter currents as low as 0.01 amps, whereas with the 500A/50mV shunt you will see currents only down to 0.1 amps. If you will be measuring current with the meter that is less than 70 Amps, then you may use either a 500A/50mV shunt or 100A/100mV shunt. The maximum current in Amps in this case is 800 divided by 12, which is 66 Amps. For example, a 12 V battery system with an inverter over 800 watts could exceed this, and the 500A/50mV shunt should be used. If you will be measuring current with the meter that is greater than 70 Amps (charging or discharging) then the 100A/100mV shunt is too small (it will overheat), and you should use the 500A/50mV shunt. There are two things to consider when deciding which to use: Which shunt should I use with the TriMetric or PentaMetric?įor medium and larger systems most people use the 500A/50mV shunt. For 48V systems it is less expensive than the TM-2020 because it does not require an extra 48 volt adapter. It is about typically about $15 more than the TM-2020. It is easier to view and enter programmed parameters. The newer TM-2025 includes better lightning protection.

(For the technically knowledgeable only): It 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 TM-2025 has a “simplified” level of operation suitable for most users, but can be configured for more flexibility (and complexity) where occasionally required. The TM-2025 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.) This also provides lightning protection for the TM-2020.
Volts of the batteries, for example to check that they are being charged at proper voltage.Įnergy 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. "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. The TM-2025-RV is physically slightly narrower, and has its own box, with more muted color scheme designed to fit with the interior of an Recreational Vehicle.Īll models are designed to monitor the following: The TM2025 A is designed to fit an a “double gang” electrical box of appropriate size, and does not come with its own box. There are also two choices of TM-2025, the TM-2025-RV and TM-2025-A, but there is no operational difference-they only differ in their size and the color of the front label.
The newer TM-2025’s have much in common, and also a few advantages over the older TM-2020, which we believe makes the TM-2025 a better choice now. This is not included with the product because some systems may already have a shunt installed. Please note that if you do not already have a shunt installed in your system, you will need to purchase one separately. The end cost, including the required shunt you will need to purchase separately, comes in under $200. They will help you maintain your batteries.

The TriMetric is used to monitor battery systems used in remote homes, RV’s or boats that have batteries that store solar, wind, or possibly generator powered chargers. Bogart Engineering TriMetric 2025 Battery System Monitor
