TM-2030 Quick Reference

P19: Reset TriMetric to factory settings
P20: Percentage overcharge compared to last discharge until float
SC-2030 solar charger only: (1-20%)
P21: Finish charge current:
SC-2030 solar charger only: enter as a percentage (0-10%) of battery capacity P3
P22: Battery charging profiles—quickly enter correct settings for SC-2030 charger
2.2.3 History data--displays only when program P7 is set to L3 or L4. Details can be found in the TM-
2030 User’s Instructions section 6.3 Using History Data.
H1: Cumulative lifetime Amp-hours drawn from the battery. Acts like an odometer for batteries.
H2-H6 History data: for each of the last five charge-discharge cycles: Use SELECT button go down the
table rows. For each row, push RESET to step back in time up to five earlier charge cycle periods.
H2.1 – H2.5 Hours since last charge/discharge cycle ended.
H3.1 – H3.5 Charge/discharge cycle duration hours.
H4.1 – H4.5 Charge efficiency of cycle: % a-hr discharged ÷ % a-hr charged.
H5.1 – H5.5 Lowest battery charge percentage within charge/discharge cycle.
H6.1 – H6.5 Lowest battery voltage within charge/discharge cycle.
H7-H9 History data: Use SELECT to go down each row. RESET to go back in time up to five days:
H7.1 – H7.5 Highest battery voltage each day.
H8.1 – H8.5 If the charge set point voltage (set in program P1) was reached on a particular day, this
parameter shows the least charge current during that time. If set point was not reached this parameter,
shows the charge current when the highest voltage was attained that day.
H9.1 – H9.5 Highest percentage of overcharge returned to the batteries for the day.

4. SC-2030 Solar Charger LED indicators – these are two lights on the SC-2030 charge controller.
The yellow LED, marked “overcurrent” when lighted indicates that at least 0.4 amp solar current is available from solar panels. If
the current exceeds 31 amps, this LED will flash while the SC-2030 limits current to a safe value.
The green LED, marked “TM-2030 Connected” indicates the charging state of the battery. When the green LED is on most of the
time, this indicates the TM-2030 is connected and solar current is available to charge the batteries. When the green LED is off
most of the time and blinking, this means the TM-2030 is not connected, or that no solar current is available. The number of
flashes indicates the state of battery charging:
Zero flashes: ready to bulk charge, but not enough solar input to charge batteries.
One flash: bulk charging.
Two flashes: battery at “absorb” voltage.
Three flashes: battery in “float” mode.
Four flashes: battery in “finish charge” mode with the SC-2030 limiting the current to P21 value.
Five flashes: battery in “finish charge” mode with the SC-2030 limiting the voltage to P15 value.
Six flashes: battery is between 98-100% charged after having been in “float”.
