TM2021-RV Battery Monitor
We have teamed with Bogart Engineering to provide a better Battery
Monitor. A smaller design with the same great features as the original
Trimetric TM2020, the TM2021-RV now comes with a second battery
bank voltage monitor, 12, 24 and 48 VDC operation, built-in lightning
protection and a 100 or 500 Amp shunt. Dimensions: 7.5cmW x
13.3cmH
The TM 2021-RV is intended to
help maintain battery systems for nominal 12V to 48V systems, such as ones found in RV’s or off grid
homes - which are regularly charged and discharged and use “deep cycle”
batteries.
The “amps” or “watts” display
measures the energy going in or out of your batteries so you can check
your charging systems, and also to see how much energy each of your
appliances use to help you conserve energy.
The “% Full” display will help
you keep track of how charged or discharged your batteries are.
The “volts” display will let
you discover if your charger systems are charging to the proper
voltage, neither too high or too low, which is important for maximizing
your battery life—also when battery voltage gets too low you will know
your battery is getting really close to being discharged.
The “days since charged”
display shows how recently the main battery (system) was fully charged,
so if it hasn’t been charged recently you can perform extra charging if
necessary to help maintain the capacity of your batteries.
The TM-2021-RV also can measure
“voltage only” of a second battery set, such as the motor starting
battery, or solar voltage input to an MPPT charge controller.
Data logging:
Not everyone will use the data
logging information, which records daily maximum battery voltage level,
and minimum charging amps to check for proper charging levels for the
last 5 days. In
addition, for up to five of the most recent charge/discharge cycles it
also logs:-
- cycle
length, charge efficiency, minimum battery% full and minimum voltage
level for each cycle.
This is useful diagnostic
information which a technician can use to determine that the whole
system is working properly.
Serial data output:
For extreme techies only: The
TM-2021-RV also has a serial 0-5V output with streaming “real time”
serial (ASCII) data that could be used to control other electronics.
