1 Important Safety Information Save These Instructions This manual contains important safety, installation and operating instructions for TRACER. The following symbols are used throughout this manual to indicate potentially dangerous conditions or mark important safety instructions，please take care when meeting these symbols. WARNING: Indicates a potentially dangerous condition. Use extreme caution when performing this task.
2 General Information 2.1 Overview Thank you for selecting the TRACER controller which represents advanced technology of our company. The features are listed below: · 12/24V auto recognition, 10A rated charging current. · Advanced maximum power point tracking technology to optimize using the solar system. · Widely used，automatic recognize day/night. · Timer function with 1-15 hours option for street light · Two load outputs.
The features of TRACER controller are shown in Figure 2-1 Figure 2-1 TRACER features.
2.2 Optional Accessories Remote Meter(Model：MT-2) The digital Remote Meter displays system operating information, error indications, and self-diagnostics read-out. Information is displayed on a backlit LCD display. The large numerical display and icons are easy to read and large buttons make navigating the meter menus easy. The meter can be flush mounted in a wall or surface mounted using the mounting frame (included). The MT-2 is supplied with 1.5m of cable and a mounting frame.
Step 1: Choose Mounting Location Locate the TRACER on a vertical surface protected from direct sun, high temperature, and water. Step 2: Check for clearance Place the TRACER in the location where it will be mounted. Verify that there is sufficient room to run wires and that there is sufficient room above and below the controller for air flow. Figure 3-1 Mounting and cooling Step 3: Mark Holes Use a pencil or pen to mark the four (4) mounting hole locations on the mounting surface.
NOTE: The TRACER is a negative ground controller. Any combination of negative connections can be earth grounded as required. Grounding is recommended. CAUTION: Don’t connect DC-to-AC inverter to the TRACER directly because the peak current of the inverter may exceed rated current of the controller when the load turns on and will initiate short circuit protection. CAUTION: The total current draw of all system loads connected to the TRACER LOAD terminals cannot exceed the 10A load current rating.
Connect load positive (+) and negative (-) to the TRACER load output as shown in figure 3-2. An in-line fuse holder should be wired in series in the load positive (+) or negative (-) wire as shown. DO NOT INSERT A FUSE AT THIS TIME. If wiring the load connection to a load distribution panel, each load circuit should be fused separately. The total load draw should not exceed the 10A load rating.
Step 3：Solar Wiring WARNING: Risk of electric shock! Exercise caution when handling solar wiring. The solar module(s) high voltage output can cause severe shock or injury. Cover the solar module(s) from the sun before installing solar wiring. The TRACER CAN ACCEPT 12V, 24V nominal off-grid solar module arrays. Grid –tie solar module(s) may be used if the open circuit voltage does not exceed the maximum solar input rating.
Figure3-5 System Wiring Review Step 6: Install Fuses Install a more than15 Amp DC-rated fuse in each fuse holder in the following order: 1. Load circuit 2. Battery circuit Step 7: Confirm Power-up When battery power is applied and the TRACER powers up, the battery led indicator will be green.
4 Operation 4.1 MPPT Technology The TRACER utilizes Maximum Power Point Tracking technology to extract maximum power from the solar module (s). The tracking algorithm is fully automatic and does not require user adjustment, TRACER technology will track the array maximum power point voltage (Vmp) as it varies with weather conditions, ensuring that maximum power is harvested from the array through the course of the day.
Figure 4-1 shows a typical current VS. voltage output curve for a nominal 12V off-grid module. Current VS. Voltage in 12V system Output power in 12V system Figure 4-1 Nominal 12V Solar Module I-V curve and output power graph The array Vmp is the voltage where the product of current and voltage (Amps×Volts) is greatest, which falls on the ―knee‖ of the solar module I-V curve as shown in Figure4-1.
Figure 4-2 shows the sequence of the stages. Figure 4-2 TRACER MPPT charging algorithm · Bulk Charge In this stage, the battery voltage has not yet reached boost voltage and 100% of available solar power is used to recharge the battery. · Boost Charge When the battery has recharged to the Boost voltage setpoint, constant-voltage regulation is used to prevent heating and excessive battery gassing.
· Equalize WARNING: Risk of explosion! Equalizing flooded battery can produce explosive gases, so well ventilation of battery box is necessary NOTE: Equipment damage! Equalization may increase battery voltage to the level damaging to sensitive DC loads. Ensure that all load allowable input voltages are greater than the equalizing charging set point voltage. NOTE: Equipment damage! Over-charging and excessive gas precipitation may damage the battery plates and activate material shedding on them.
· Charging State Indicator The green LED indicator will light whenever sunlight is available for battery charging, the green charging LED will stay on in normal charging. The charging LED indicator flashes when system over voltage. Please refer to Chapter 5 for troubleshooting.
4.4 Setting Operation . Load Control Settings 1. Dusk to Dawn (Light ON+Light OFF) When solar module voltage goes below the point of NTTV (Night Time Threshold Voltage) at sunset, the solar controller will recognize the starting voltage and turn on the load after 10 minutes delay; When solar module voltage goes above point of DTTV (Day Time Threshold Voltage), the solar controller will recognize the starting voltage and turn off the load after 10 minutes delay. 2.
Press the Setting Switch, and the led will switch between load 1 timer, load 2 timer and battery type. Press the Setting Switch for 5 seconds when the led is on load 1 timer setting. The led will be flashing. Continue to press the setting switch and the number will repeat from 0 to 17, and stop pressing when the desired number appears according to the following setting table. Setting work mode of load 2 is the same as load 1 when the led is on load 2 timer setting. LED Work Mode of Load Digital No.
If either of the two loads is TEST MODE. The two loads will be TEST MODE simultaneously. If either of the two loads is ON/OFF MODE. The two loads will be ON/OFF simultaneously. But there is an exception, as long as one of the loads is TEST MODE, the TEST MODE will prevail. · Battery Type Setting Press Setting Switch and hold on 5 seconds when the led is on battery type setting mode. The led will be flashing.
· Load Short Circuit Fully protected against load wiring short-circuit. After two automatic load reconnect attempts (10 seconds between each attempt), the fault must be cleared by removing and reapply power. · High Voltage Input If the solar input open circuit voltage (Voc) exceeds the maximum input voltage of TRACER (TRACER 1206/60VDC; TRACER 1210/100VDC; TRACER 1215/150VDC), the array will remain disconnected until the Voc falls safely below the maximum rating.
5.2 Troubleshooting Troubleshooting according to the following instructions: Faults Possible reasons Charging LED indicator PV array disconnection is off during daytime Troubleshooting Check that PV and battery wire connections are correct and tight. and sunshine falls on PV modules properly. Green charging LED indicator is fast flashing Battery voltage higher Check if battery voltage Over high.
Note：If no charging LED indication when the connection is normal Measure the PV input voltage at the PV terminals, input voltage must be greater than battery voltage before charging begins. 5.3 Maintenance The following inspections and maintenance tasks are recommended at least two times per year for best controller performance. Check that the controller is securely mounted in a clean and dry environment. Check that the air flow and ventilation around the controller is not blocked.
6 Warranty The TRACER-MPPT charge controller is warranted to be free from defects for a period of TWO (2) years from the date of shipment to the original end user. Epsolar will, at its option, repair or replace any such defective products. • Claim procedure: Before requesting warranty service, check the Operator’s Manual to be certain that there is a problem with the controller.
