Product Updates, Bugs & Issues

A note for customers experiencing issues that purchased  our products from April to November of 2014:

A series of firmware issues were present in versions 1.0-2.0 of TriMetric TM-2030 meters  made from April 2014 to November 2014.  These were labelled with serial numbers up to 1657.    Please follow the -Bugs in TM-2030 and SC-2030 link for more information.  If you believe you have a product with a known firmware error, and have verified the version and serial number (located on the back of the unit’s panel), please contact us right away.

Product Updates:

All product updates have been incorporated into present products unless otherwise noted.

TM-2030 & SC-2030: Firmware as of August 2018 – ver 2.8 for TM-2030 and ver 11 for SC-2030.  Refinements to PWM control algorithm in both units for faster improved performance.

For TM-2030, August 2016, firmware version 2.5:  Allows for connection of 2 SC-2030s for up to 62 amps current.  Connecting kit required.  Firmware version 9 for SC-2030 also required.

For TM-2030, January 2015, firmware version 2.2: When using the TM-2030 Monitor to control the SC-2030 Solar charger, this update adds an option to deliver a manual equalization cycle (a higher voltage overcharge) to batteries. Also adds a display item: In addition to the “rPC” display that shows the amount of percent charge replaced compared to previous low discharge, it now allows viewing the amp hour value of the low discharge upon which “rPC” is based.  

For TM-2030, October 2014: This update applies to people using the TM-2030 Monitor to control the SC-2030 Solar Charger. Proper charging sometimes results in battery voltage that goes higher than some components connected to the batteries can tolerate, particular in RV’s. As an expedient, this update allows you to set a maximum upper limit  voltage that the SC-2030 charger is allowed to charge. 

New Program Mode for TM-2030 to Limit Maximum Voltage

SC-2030 Product Issue:  We have found that a few installers have wired the Solar Input, or the Battery output with reversed connections to the SC-2030–for example with Solar input minus going to + , and + going to minus in. This instantly damages the SC-2030.  We have added (2016) a minor change to the design that prevents this from happening.  We still highly recommend checking carefully the + and – polarity before connecting…although we expect that with the modified design damage will not occur when connected with reversed polarity.
