Bogart Engineering TriMetric 2030 TM-2030-RV-F >
12/24/48 Volt Battery System Monitor

* The recommended fuse holder and 1 Amp fuse are now included.
You will need to purchase a shunt separately. 100 or 500 amp shunts are used most often.

The 2030RV-F comes with its own cream colored enclosure designed to be surface mounted to a wall, so does not need an additional mounting enclosure!

The TriMetric TM-2030 is Bogart's new battery monitor. It is a stand-alone monitor, but it can also work in tandem with the new SC-2030 charge controller for optimized battery life, capacity use and efficiency.

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 is not included.

Warranty: Bogart Engineering warranty policy is to repair at no cost any of their products that develop a problem not due to customer misuse.


  • New “Percent Full” display (“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.


  • Operates with (nominal) battery systems from 12 to 48V.
  • Can now monitor the 'voltage only' of a second battery set, such as a starting battery, or possibly also the input voltage of a solar array (if less than 100 volts.)
  • Improved lightning protection built in, without having to use adapter.
  • New 'low battery alarm'. A new display shows Replaced Percentage (rPC): shows how much of the most recent discharge has been replaced to your batteries during the next day's charging. Ideally this should reach 110% or even more.
  • Serial data output with streaming of real-time data that can be used to control other electronic devices.
  • Minimal data logging, which can be useful for a technician to diagnose some common setup or operational problems with battery systems.
