1. Primary System Information

The most important information on your battery system is available simply by pressing the select button a number of

times on the TriMetric front panel. As the select button is pressed, the following appear on the display:

1. volts: the voltage of your main battery (if the B1 lamp is on) or the voltage of the secondary battery (if the B2

lamp is on). Use volts to:

a. Check whether your batteries are charging at the voltage speciﬁed by the battery manufacturer

b. Check whether the batteries are nearing a low state of charge. This would be (for 12 V system) when volts

are somewhat less than 12.0 volts. Between 12.0 to 14.0 volts this display is a poor indicator of state of

charge in a working system. Use % full instead.

2. amps (or watts): this mode shows how rapidly energy is entering or leaving the battery. It is positive when the

battery is being charged or negative when the battery is being discharged. This display mode can be

reconﬁgured (using program P4) to show power (in Watts) instead of showing current (in Amps). Use amps or

watts to:

a. Verify that the charger is charging the batteries at correct rate;

b. Know when to turn a charging generator off. As batteries become more charged, amps to the batteries will

decline. Running a generator with a low charge current is wasteful;

c. Learn the power usage of your various appliances by noting the amps (or watts) difference when they are

switched on and off. Do this when you are not charging batteries.

d. Check that all your appliances are really turned off before leaving home.

3. % full: this display mode tells the state of charge (how much energy is left) in the battery on a percentage scale.

Use this mode to:

a. minimize generator run time when charging batteries by running it when “% full” is low and thus charging

amps are higher. When % FULL is high, ﬁnish charging with solar at lower amps and longer charge times

b. Observe progress while charging.

2. Additional System Information

In order to display additional system information, hold the select button down continuously. The following display modes

will then appear in the order below, repeating as long as select is held. Programmable settings and history data are

described below only in summary form. Refer to the SC-2030 user guide for further details on these advanced display

modes.

1. Secondary information, indicated by “Ahr” on the display. The ﬁrst ﬁve items in this category are listed in lower

box on the front panel. See Section 2.1 below for description.

2. Programmable settings, indicated by “P” on the display; see Section 2.2 below.

3. History data, indicated by “H” on the display; see section 2.3 below.

4. Primary system information will be repeated as well, as described in Section 1 above.

2.1. Secondary System Information

These are shown in lower box on front label. When the display mode is selected for secondary information, the following

information is available:

Ahr: Amp-hours from full. This is another way to indicate percentage full. When the battery is full, this value is zero.

When the battery is less than full, the value is a negative number which shows how many amp-hours should be

returned to the battery to fully charge it. That number is reset by holding the reset key down for at least ﬁve

seconds while in that display mode. For best accuracy, reset this parameter only when you are certain the

battery is fully charged.

dSC:Days since charged: This value shows the number of days since the battery was last fully charged. It is important

to not let the battery at a low charge level for long periods of time. It is reset automatically when the “charged

criteria” are met, however it can be manually reset by holding the reset key down for at least ﬁve seconds while

in that display mode.

dSE: Days since equalized (“dSE” on display): This provides a reminder for when to perform a manual equalization.

Shows how many days have elapsed since the last time the battery was equalized. This number is not

automatically reset; it must be reset by holding the reset key down for at least ﬁve seconds while in that display

mode.

“Pr” or “AP”: Power (“Pr” on display indicating watts) or current (“AP” on display indicating amps), depending on

whether the amps primary display was set for current or power, respectively. This allows both Watt and Amps

information to be available in all cases: as one is available as primary information, the other is available as

secondary information.

rPC: Percent returned from last discharge. Because of batteries’ inherent inefﬁciency, it is necessary to recharge

batteries with more energy than was taken out. Flooded batteries require at least 10% more charge than was

removed, while AGM batteries need only about 5–8% more. While the battery is being discharged, the value

shown is 0. While the battery is being charged, the value is the amount of charge added so far as a percentage

of the amount of charge last removed, or anywhere from 0% to 110% or more.

The following three are not shown on front label. The SC-2030 must be connected and communicating with the

TM-2030. They only display when the sun is supplying power to the SC-2030 charger

ºC: The battery temperature in degrees Celsius

SOL: Solar amperes: the amount of current being delivered from the solar panels from SC-2030.

UPr: Unused solar power: shows if extra power is available from sun that could be used when battery charging is

tapering down in the afternoon. Run appliances such as a dishwasher or vacuum when this extra power is

available, which would otherwise be wasted. Displays “YES” when nearly all solar power available for extra

use. If a number is displayed it is showing watts available.

2.2. Programmable Settings. More details can be found in the SC-2030 user guide.

Two sets of programmable settings are available. The basic set is always available. The advanced set is available only

when the “user level” has been set to L3 or higher using setting P7, which is necessary when using the SC-2030. This

section describes the programmable settings in summary form.

2.2.1.Basic Programmable Parameters

The following parameters comprise the basic set:

⁃P1: Charged voltage set point. Bulk charging of the battery stops when the voltage has reached this limit.

(10-65V)

⁃P2: Current threshold prior to switching to ﬁnish charging. When the charging current drops below the level set by

this parameter, expressed as a percentage of the battery’s capacity (P3), the state of the charger changes from

bulk charging to ﬁnish charging. The charging current is then limited to the value set in P21 described in the

section below. It is recommended that not more than 5% be used. (OFF or 0.1-9.9%)

⁃P3: Battery system capacity in Amp-hours (10-9990 A-hr)

⁃P4: Current (“A”) or power (“Pr”) in amps primary display mode

⁃P5: Days-since-charged alarm set point (off, 0.0-250 days)

⁃P6: Days-since-equalized alarm set point (off, 0.0-250 days)

⁃P7: User level, required to access the advanced parameters (L1, L2, L3, L4)

2.2.2.Advanced Programmable Parameters

The advanced parameters can be accessed only if the user level has been set to L3 using program P7. Default values

are reinstalled whenever P7 is switched to L1 or L2.

⁃P9: Low-battery beeper alarm threshold (OFF, 1–100%). Setting this parameter to “OFF” disables the beeper

alarm both for low battery charge percentage (this parameter) and for low battery voltage (P13 parameter).

Default: OFF

⁃P10: Efﬁciency factor (60–100%). This parameter affects how the “% full” and “amp hours from full” values are

evaluated. Discharging amps are always evaluated at 100%. Charging amps are evaluated at this lesser percent

to account for battery charging inefﬁciency. Default: 94%

⁃P11: Shunt type. “H” means 500A/50mV and “L” means 100A/100mV. Default: H

⁃P12: Auto reset. When “OFF,” percent full and amp hours are never automatically reset. Default: On

⁃P13: Low battery voltage alarm setting (10.0-65.0 V) Default: 10.0

⁃P14: Maximum allowed ﬁnish-charge time in hours until ﬂoat (0.0-5.0) Default: 0.0

⁃P15: Maximum ﬁnish-charge voltage (10.0-65.0 V)

⁃P16: Float-voltage setting (10.0-65.0 V)

⁃P17: Hours before history data is recorded: for data H7, H8 and H9 (0-24)

⁃P18: Adjust battery calibration voltage.

⁃P19: Reset TriMetric to factory settings.

⁃P20: Percentage of overcharge compared to last discharge until ﬂoat (1-20%)

⁃P21: Finish charge current limit: speciﬁes current as a percentage of the battery capacity (0-10%)

⁃P22: Battery charging proﬁles—to quickly enter correct charger settings for SC-2030.

2.3. History Data. More details can be found in the TM-2030 user guide.

The following system history is stored for diagnostic purposes. Parameter H1 is accumulated over the battery’s lifetime

until reset manually. Parameters H2–H6 hold data for the last ﬁve charge-discharge cycles. Parameters H7–H9 hold

data for the last ﬁve days of operation.

⁃H1: Cumulative lifetime Ampere-hours drawn from the battery

History data of the last ﬁve charge-discharge cycles:

⁃H2-1 – H2-5: Hours since last cycle ended

⁃H3-1 – H3-5: Cycle duration in hours

⁃H4-1 – H4-5: Charge efﬁciency of cycle: percentage of total Ampere-hours discharged ÷ Ampere-hours charged

⁃H5-1 – H5-5: Lowest battery charge percentage within the cycle

⁃H6-1 – H6-5: Lowest battery voltage within the cycle

History data of the last ﬁve days:

⁃H7-1 – H7-5: Highest battery voltage each day

⁃H8-1 – H8-5: If the charge set-point voltage (set in P1) was reached on a particular day, this parameter shows the

charge current at that time. If the charge set-point voltage was not reached, this parameter shows the charge

current when the highest voltage was attained.

⁃H9-1 – H9-5: Highest percentage of overcharge returned to the battery for the day

4. SC-2030 led Indicators.

The led lights are located on the charge controller usually near the batteries. The yellow led, marked “Overcurrent” on

the SC-2030, indicates that current is available from the solar panel to charge the battery. If the current is excessive

(over 32A), the led will ﬂash while the SC-2030 limits the current into the battery. If a lower amount of current is available,

the yellow led will be on without ﬂashing.

The green led, marked “TM-2030 Connected” on the SC-2030, indicates the charging state of the battery. When the

green led is on most of the time, this means the TM-2030 is connected and solar current is available to charge the

battery. When the green led is off most of the time and blinking, this means the TM-2030 is not connected, and the

charge controller is charging the battery. The number of ﬂashes indicates the state of battery charging:

1. One ﬂash: bulk charging

2. Two ﬂashes: battery at “absorb” voltage

3. Three ﬂashes: battery in “ﬂoat” mode

4. Four ﬂashes: battery in “ﬁnish charge” mode with the SC-2030 limiting the current

5. Five ﬂashes: battery in “ﬁnish charge” mode with the SC-2030 limiting the voltage

6. Six ﬂashes: ready to bulk charge, but not enough solar input (compared to loads) to charge batteries.
