GENERAL INFORMATION

Overview

Based on a digital control circuit, the Tracer2206AN controller contains a self-adaptive three-stage charging mode. It assists to prolong the battery lifespan and improves the system’s performance. It is also equipped with electronic protection to ensure a more reliable solar system. This controller can be widely used for camping, caravanning, and boating as well as at-home applications.

Features

• Advanced MPPT, with an efficiency no less than 99%
• Maximum DC/DC conversion efficiency of 96%
• Automatic limitation of the charging current and charging power
• Wider MPPT working voltage range
• Applicable for lead·acid and lithium batteries
• Programmable temperature compensation feature
• Multiple load work modes

Characteristics

Suppose the remote temperature sensor is not connected to the controller or is damaged. In that case, the controller will charge or discharge the battery at the default temperature setting of 25 °C (no temperature compensation).

Maximum PowerPoint Tracking Technology

Due to the nonlinear characteristics of the solar array, there is a maximum energy output point (Max PowerPoint) on its curve. Traditional controllers, equipped with switch charging technology and PWM charging technology, can’t charge the battery at the maximum power point and cannot obtain the maximum energy available from the PV array. In contrast. the solar charge controller with Maximum Power Point Tracking (MPPT) Technology can lock the point to obtain the maximum energy and deliver it to the battery. As Figure 1-2, the curve is also the array’s characteristic curve; the MPPT technology will ‘boost’ the battery charge current by tracking the MPP. Assuming 100% conversion efficiency exists in the solar system. the following formula is established:

Normally, the Vww is always higher than Ve.1. Due to the principle of energy conservation, the leat is always higher than IPv. The greater the difference between VMw & Vea1, the greater the difference between IPv & le.1. The greater the difference between the array and the battery will also decrease the system conversion efficiency. Therefore, the controller’s conversion efficiency is particularly important in the PV system. Figure 1-2 is the maximum power point curve, whose shaded area is the traditional solar charge controller (PWM Charging Mode). It is known that the MPPT mode can improve solar PV usage. According to the test, the MPPT controller can raise 20%-30% efficiency compared to the PWM controller. (Specified value may be fluctuant due to the influence of the circumstance and energy loss.)

In actual application, as shading from cloud, tree, and snow, the panel may appear Multi-MPP. However, in actuality, there is only one real Maximum Power Point. As the below Figure 1-3 shows:

Suppose the program works improperly after appearing Multi-MPP. In that case. the system will not work on the real max power point. which may waste most solar energy resources and seriously affect the system’s normal operation. The typical MPPT algorithm can track the real MPP quickly and accurately. It can improve the PV array’s utilization rate and avoid resource waste.

Battery charging stage

The controller has a three-stage battery charging algorithm, including Bulk Charging, Constant Charging, and Float Charging. Through the three-stage charging method, the system can extend the battery’s lifespan.

Bulk Charging
The battery voltage has not yet reached constant voltage (Equalize or Boost Charging Voltage). The controller operates in constant current mode, delivering its maximum current to the batteries (MPPT Charging). When the battery voltage reaches the constant voltage set point. the controller will start to operate in constant charging mode.

Constant Charging
When the battery voltage reaches the constant voltage set point, the controller will start to operate in constant charging mode. The MPPT charging stops during this process, and the charging current will drop gradually at the same time. Constant charging has two stages, namely, equalizing charging and boosting charging. These two charging processes are not repeated.

Boost Charging
The default duration of the boost charging stage is generally 2 hours. Customers can also adjust the constant time and preset value according to actual needs. When the duration is equal to the set value. the system will switch to the float charging stage.

Equalize Charging

| Explosive Risk! Equalizing flooded batteries would produce explosive gases, so well ventilation of the battery box is recommended.
---|---

| •  Equipment damage!

•   Equalization may increase battery voltage to the level that damages sensitive DC loads. Verify that the load’s allowable input voltages are greater than the equalizing charging setpoint voltage.

•  Over-charging and excessive gas precipitation may damage the battery plates and activate material shedding on them. Too high an equalize charging or for too long may cause damage. Please carefully review the specific requirements of the

the battery used in the system.

Some battery types benefit from equalizing charging, stirring electrolytes, balancing battery voltage, and accomplishing chemical reactions. Equalized charging increases the battery voltage to make it higher than the standard complement voltage, gasifying the battery electrolyte. If the controller automatically controls the next charge for equalizing charging, the equalizing charging time is 120 minutes. Equalize charge and boost charge are not carried out constantly in a full charge process to avoid too much gas precipitation or overheating of the battery.

| •  Due to the installation environment or load work, the system may not stabilize the battery voltage at a constant voltage. The controller will accumulate the time when the battery voltage is equal to the set value. When the accumulative time is equal to 3 hours, the system will automatically switch to float charging.

•  If the controller time is not adjusted. the controller will equalize charging following

the inner time.

---|---

Float Charging
After the constant charging stage, the controller will reduce the battery voltage to the float charging preset voltage by reducing the charging current. During the floating charge stage, the battery is charged weakly to ensure that the battery is maintained in a fully charged state. In the float charging stage, loads can obtain almost all power from the solar panel. Suppose the loads’ power exceeds the solar array’s power. In that case, the controller will no longer maintain the battery voltage in the float charging stage. When the battery voltage goes lower than the set value of the boost recharge voltage, the system will exit the float charging stage and enter the bulk charging stage again.

INSTALLATION

Warning

• Be careful when installing the batteries. Please wear eye protection when installing the open-type lead-acid battery and rinse with clean water in time for battery acid contact.
• Keep the battery away from any metal objects, which may cause a short circuit of the battery.
• Acid gas may be generated when the battery is charged. Confirm that the surrounding environment is well-ventilated.
• Avoid direct sunlight and rain infiltration when installing it outdoors.
• Loose power connectors and corroded wires may result in high heat that can melt wire insulation. burn surrounding materials. or even cause a fire.
• Ensure tight connections and secure cables with cable clamps to prevent them from swaying in moving applications.
• Only charge the lead-acid and lithium-ion batteries within the control range of this controller.
• The battery connector may be wired to another battery or a bank of batteries. The following instructions refer to a singular battery. Still. it is implied that the battery connection can be made to either one battery or a group of batteries in a battery bank.
• Select the system cables according to 5A/mm’ or less current density.

Requirements for the PV array
Serial connection (string) of PV modules As the core component of the solar system, the controller needs to suit various types of PV modules and maximize solar energy conversion into electricity. According to the open-circuit voltage (Voe) and the maximum power point voltage (VMPP) of the MPPT controller. the serial connection of PV modules suitable for different controllers can be calculated. The below table is for reference only.

---|---

Max. PV Array Power

• The MPPT controller has the function of current/ power-limiting. Namely, when the charging current or power exceeds the rated value, the controller will automatically reduce the actual charging current or power to the rated value. The function can effectively protect the charging parts of the controller and prevent damage to the controller due to the connection of some over-specification PV modules. The actual PV array running status shows as below:
• Condition 1: Actual charging power of the PV array $ Rated charging power of the controller
• Condition 2: Actual charging current of the PV array $ Rated charging current of the controller When the controller operates under “Condition 1″ or ” Condition 2″, it will carry out the charging as per the actual current or power; at this time, the controller can work at the maximum power point of the PV array.
• Condition 3: Actual charging power of the PV array> Rated charging power of the controller
• Condition 4: Actual charging current of the PV array> Rated charging current of the controller When the controller operates under ” Condition 3″ or ” Condition 4,” , it will carry out the charging as per the rated current or power.

| The controller may be damaged when:

The PV array’s maximum open-circuit voltage is more than 60.

---|---

According to the “Peak Sun Hours diagram,” if the PV array’s power exceeds the controller’s rated charging power, the charging time as per the rated power is prolonged. The controller can obtain more energy. However, in the practical application, the maximum power of the PV array shall be not higher than 1.5 times the rated charging power of the controller. Suppose the maximum power of the PV array exceeds the rated charging power of the controller too much. In that case, it causes the waste of the PV array and increases the PV array’s open-circuit voltage, which may increase the probability of damage to the controller. For the recommended maximum power of the PV array. please refer to the table below:

Wire size
The wiring and installation methods conform to the national and local electrical code requirements.

PV wire size
The PV array’s output current varies with its size. connection method, and sunlight angle. The minimum wire size can be calculated by its ISC (short circuit current). Please refer to the ISC value in the PV module’s specifications. When the PV modules are connected in series, the total ISC equals any PV module’s ISC. When the PV modules are connected in parallel, the total ISC equals the sum of the PV module’s ISC. The PV array’s ISC must not exceed the controller’s maximum PV input current. For max. PV input current and max. PV wire size, please refer to the table as below:

exceed the max. PV open circuit voltage 46V at 25°C environment temperature.
---|---

Battery and Load Wire Size
The battery and load wire size conform to the rated current, the reference size as below:

Model

| Rated charge current| Rated discharge current| Battery wire size| Load wire size
---|---|---|---|---
Tracer2206AN| 20A| 20A| 6mm2/ IOAWG| 6mm 2 / IOAWG
| •  The wire size is only for reference. Suppose there is a long distance between the PV array and the controller or between the controller and the battery. In that case, larger wires can be used to reduce the voltage drop and improve performance.

•  The recommended wire is selected for the battery according to the conditions

that its terminals are not connected to any additional inverter.

---|---

Mounting

| •   Risk of explosion! Never install the controller in a sealed enclosure with flooded batteries! Do not install the controller in a confined area where battery gas can accumulate.

•   Risk of electric shock! When wiring the PV modules, the PV array may generate a high open-circuit voltage. Turn off the breaker or fuse firstly, and be careful

when wiring.

---|---
| The controller requires at least 150mm of clearance above and below for proper airflow. Ventilation is highly recommended if mounted in an enclosure.

Installation procedures

Step 1: Determine the installation location and heat-dissipation space

Step 2: Connect the system in the order of battery following Figure 2-2,” Schematic Wiring Diagram,” and disconnect the system in the reverse order.

Technical Specifications

| •  Please do not close the circuit breaker or fuse during the wiring and ensure that the leads of “+” and “-” poles are polarity correctly.

•   A fuse whose current is 1.25 to 2 times the controller’s rated current must be installed on the battery side with a distance from the battery no longer than 150 mm.

•  If an inverter is to be connected to the system, connect the inverter directly to

the battery, not to the load side of the controller.

---|---

Step 3: Grounding

Tracer2206AN is the common-negative controller. Negative terminals of the PV array, the battery, and the load can be grounded simultaneously, or any negative terminal is grounded. However. according to the practical application, the negative terminals of the PV array, battery, and load can also be ungrounded. However, the grounding terminal on its shell must be grounded. It shields electromagnetic interference and avoids electric shock to the human body.

| For common-negative systems, such as the RV system, it is recommended to use a common-negative controller. If a common-positive controller is used and the positive electrode is grounded in the common-negative system, the controller may be damaged.
---|---

Step 4: Connect accessories

• Connect the temperature sensor

Connect one end of the remote temperature sensor to the interface.

| Suppose the remote temperature sensor is not connected to the controller or is damaged. In that case, the controller will charge or discharge the battery at the default 25 °C (no temperature compensation).

Load short circuit protection

| When a short circuit occurs on the load side (which is 4 times higher than the rated load current), the controller automatically cuts off the output. The output still attempts to resume five times automatically (delay 5 seconds, 10 seconds, 15 seconds, 20 seconds, 25 seconds). Suppose you want the controller to restart the auto-recovery process. In that case, you need to press the Load button, or restart the controller, or experience a night-to-day change (nighttime> 3 hours).

Overload protection

| If the load current exceeds 1.05 times the controller’s rating, the controller will cut off the output after a delay. After the overload occurs, the output attempts to resume automatically five times (delay of 5 seconds, 10 seconds, 15 seconds, 20 seconds, 25 seconds). Suppose you want the controller to restart the auto-recovery process. In that case, you need to press the Load button, or restart the controller, or experience a night-to-day change (nighttime> 3 hours).

Device overheating protection

| An internal temperature sensor can detect the internal temperature of the controller. The controller stops working when it s internal temperature is higher than 85 and resumes working when its internal temperature is below 75°C.

| TVS high voltage transients protection| The controller’s internal circuitry is designed with Transient Voltage Suppressors (TVS,) which can only protect against high-voltage surge pulses with less energy. Suppose the controller is to be used in an area with frequent lightning strikes. In that case, it is recommended to install an external surge arrester.

When the controller’s internal temperature reaches 8 1°C, the charging power automatic reduction function is enabled. Temperature increases by 1°C, the charging power is reduced by 5%, 10%, 20%, and 40%. If the internal temperature is higher than 85°C, the controller stops charging the battery.
When the internal temperature is not more than 75°C, the controller resumes charging per the rated charging power.

Troubleshooting

PV array open-circuit

| When there is plenty of direct sunlight on the PV array, the LCD shows|

Confirm whether the connection of the PV array is correct and tight

The battery voltage is lo we r than av| The wire connection is correct: the controller is not working| Please check the voltage of the battery (at least av

voltage to activate the controller)

Battery over voltage

|

Battery frame blink

| Check whether the battery voltage is higher than (over-voltage disconnect voltage) and disconnect the

PV array connection

Battery over-discharged

| Battery frame blink| (1) When the battery voltage is restored to or above LVR (low voltage reconnect voltage). the load will recover.

(2) Takeother ways to recharge the battery

Battery overheating

1.    Load off

2.                Load and fault

| (!)Please reduce the number of electric devices. start the controller or pressthe button to clear faults

Load short-circuit

| (!)Check carefully the load’s connection, clear the fault,

®Restart the controller or press the button to clear faults

When the load current goes higher than 1.02-1.05 times, 1.05-1.25 times, 1.25-1.35 times, and 1.35-1.5 times the rated value, the controller may automatically turn offloads in 50 seconds, 30 seconds,10 seconds, and 2 seconds r respectively.

Maintenance

The following inspections and maintenance tasks are recommended at least two times per year for good performance.

• Make sure no block on airflow around the controller. Clear up any dirt and fragments on the radiator.
• Check all the naked wires to ensure insulation is not damaged by sun exposure, frictional wear, dryness, insects or rats, etc. Repair or replace some wires if necessary.
• Verify the indicator display is consistent with the actual operation. Pay attention to any troubleshooting or error conditions. Take necessary corrective action.
• Confirm that terminals have no corrosion, insulation damage, high temperature, or burnt/discolored sign, and tighten terminal screws to the suggested torque.
• Clear up dirt, nesting insects, and corrosion in time.
• Check and confirm that the lightning arrester is in good condition. Replace a new one in time to avoid damaging the controller and even other equipment.

CAUTION

| Risk of electric shock! Ensure that the power is turned off before the above operations, and then follow the corresponding inspections and operations.
