4.4.4 Mount the enclosure on vertical surface so the heat sink fins go up and down. Use two screws on flanges, or you may
drill your own holes internally and use those.
4.4.5 Connect the temperature sensor connector (if used) and the communication cable to the two connectors on the back of
the SC-2030 (inside the box). Place the circuit board back onto the enclosure board and secure with four screws.
4.4.6 Place the temperature sensor (if used) near the batteries. The hole in the sensor could be connected to a battery
terminal—but this is not necessary for it to measure temperature.
For safety, turn off power from batteries and solar panels before doing next step
4.4.7 Connect the wires from batteries and the solar panel wires to the controller. For the following steps, refer to
wiring diagram, Figure 1 on page 3. For safety, turn all switches and circuit breakers off while
making the connections. While voltages in a 12V or 24V solar system are generally considered safe
from electrical shock, amperages can be very high and can create powerful arcs if accidentally
shorted, or when connections are made or unmade.
a. Connect the SC-2030 minus wire to the batteries. Observe in figure 1 (page 3) how the SHUNT is connected
to the batteries. The shunt has two large bolt terminals. One is connected to the battery negative terminal—
the other side is connected to the loads in your system. The wire from the SC-2030 “BATTERY minus”
terminal (large green) must go to the LOAD side of the shunt. Avoid a common mistake of connecting this
directly to the negative post of the battery. If you make this mistake the solar current will not register as
“amps” on your TM-2030, and charging will not be correctly controlled by the TM-2030.
b. Connect the wire from the battery + terminal to large green connector on the SC-2030 marked BATTERY +.
c. Connect two solar panel wires to the two large green terminals on the SC-2030 identified on the SC-2030 as
“SOLAR” . Be sure to observe correct polarity: + from panels to terminal marked SOLAR +, and minus to
terminal marked SOLAR “ —“.
4.4.8 Connect communication connector at TM-2030 end if not already connected.
4.4.9 Verify all wiring and polarities (plus and minus not reversed). Then close the switches or circuit breakers.
4.5 Verifying SC-2030 operation and programming charging parameters.
NOTE: References to “P” numbers such as P4, P16, etc. refer to user programmable values explained on page 12.
●When solar is shining on the panels with more than 0.5 amps the amber light on the SC-2030 should be ON. When
flashing every half second, it is in over current protection and charger is limiting current to a safe value for charging.
4.5.1 If the SC-2030 is connected to a TM-2030 while sun is shining on panels: Check the green light on the SC-2030
Solar Charge Controller. If the two units are communicating it should be ON most of the time—but possibly
occasionally blink off. If the green LED is off or mostly off, except for occasional blinks on, check the
communication cable again, check that the TriMetric is powered and operating properly, and also verify that the phone
cable contacts are crossed as shown in the lower right-hand corner of Figure 1. Also, there must be at least a small
amount of solar current coming from the solar panels.
4.5.2 If the SC-2030 is operating without the TriMetric: If at least a little solar energy is coming in, the amber light will
be on, but the green LED will be usually off—but every 10 seconds or so will blink on to indicate the charge state as
indicated in next section 4.5.3.
4.5.3 The flashing green light on the SC-2030 will tell you what charging state the SC-2030 is: The following sequence
will be repeated every 10 seconds or so:
●Flashing once, the charger is in the first stage or “bulk” charging.
●Flashing twice, charging at the absorb voltage
●Flashing 3 times indicates floating mode.
●Flashing 4 times: in higher voltage “finish,” limited current charging. (With TM-2030 connected only)
●Flashing 5 times: at maximum voltage “finish,” limited current charging. (With TM-2030 connected only)
●Flashing 6 times: Was in float, now discharging but still at least 98% full. (With TM-2030 connected only)
●Flashing zero times: Discharging and less than 98% full (With TM-2030 connected only)
4.5.4 Last important step: Programming the SC-2030 for your battery system when TM-2030 is connected.
Easy way: Most people will choose the easy way to enter this data. This method automatically enters 8 charging
parameters to control the charging, and also provides proper monitoring in most cases. This requires the following
three steps:
STEP 1. Find the "charging profile number" from the table below depending on the type of batteries and system voltage you
have, 12 or 24 volts. If yours is not on the chart, and you have liquid electrolyte batteries (with caps on top for watering)
you could start with "Generic" profile 1 or 2. If you have AGM batteries, start with profile 9 or 10. (See "Concorde" on
chart)
