Overview 1.1Information & Features DuoRacer MPPT charge controller is made for charging two batteries (shown as BATT1 and BATT2 below) at the same time in a solar system. This controller supports multiple life battery (BATT1) types, including Sealed, Gel, Flooded, LiFePO4, and Li-NiCoMn, which is suitable for RV, Camper, Boat, and so on. The device recognizes the start battery (BATT2) system voltage automatically, and trickle charges the battery when the conditions are satisfied. The controller adopts the advanced MPPT control algorithm,which will minimize the maximum power point loss rate and loss time,also fast track the maximum power point(MPP) of the PV array, and obtain the maximum energy from solar array under any conditions. The energy utilization in the MPPT solar system is increased by 20-30% compared with PWM charging method. When there is no manual operation for a long time, and the charging conditions cannot be reached, the controller will turn to low-power mode, which reduces the loss and battery power waste to enhance the products life. The system parameters are shown and set by LED/LCD or the MT11 remote meter (Accessory). The AES control signal of the car refrigerator is built in the controller, which will supply the surplus solar power to the refrigerator to avoid energy waste. The controller comes with IP33 protection level, which is waterproof and dustproof. Multiple protection features, including battery overcharge protection, over discharge protection, and reverse connection protection of the PV and battery, which effectively ensure the solar system safety, stability, and lifetime. Features Maximum Power Point Tracking technology with ultra-fast tracking speed and the tracking efficiency is no less than 99.5% guaranteed Advanced MPPT control algorithm to minimize the MPPlost rate and lost time The wider range of the MPP operation voltage to improve the PV module utilization Auto control function of charging power & charging current limitation(BATT1) High quality and low failure rate components of ST, TI and Infineon to ensure the product life Digital circuit control of adaptive three-stage charging mode to enhance BATT1 life. BATT1 type can be set via LED/LCD. Product runs into the low-power mode when there is no manual operation for a long time, and charging conditions are not satisfied (PV<5V). 100% charging and discharging in operationenvironmental temperature range. 1 LED and LCD dispiay units selectable. AES control signal for car refrigerator to avoid energy waste. Standard Modbus protocol, and RS485 (5V/200mA) communication port for the customer to expand the application area. Life battery (BATT1) is the energy storage battery for powering the household loads in the off-grid system, which supports Sealed, Gel, Flooded, LiFePO4, and Li-NiCoMn batteries (the controller can NOT recognize the system voltage automatically). Start battery (BATT2) is the energy storage battery which usually built in the vehicle for powering the system such as RV and Boat, and only supports lead-acid battery (the controller will recognize the system voltage automatically). NOTE: the BATT1 and BATT2 must be at the same voltage level. 1.2 Name definition 1.3 Structure 2 Mounting hole size5mm BATT1 terminals LCD(Refer to chapter 3) Grounding Terminal BATT2 terminals RS485 Communication port Remote temperature sensor port AES (signal) output port PV terminals Terminal protection cover The controller is charging the BATT1 as default (25) without temperature compensation function when it's not connected to the remote temperature sensor, or the temperature sensor is damaged. The temperature compensation is ONLY designed for the lead-acid battery, for lithium battery, there is no temperature compensation. AES port which output is 12V/200mA and RS485 Port which output is 5V/200mA are independent of DR1106/2106/3106N models, the AES port output voltage is the battery voltage.

Installation 2.1 Warning Be very careful when installing the batteries, especially flooded lead-acid battery. Please wear eye protection, and have fresh water available to rinse if any contact with battery acid. Keep the battery away from any metal objects, which may cause short circuit of the battery. Explosive battery gases may come out from the battery during charging, so make sure ventilation condition is good. For outdoor installation, keep out of the direct sunshine and rain infiltration. Loose connections and corroded wires may result in high heat that can melt wire insulation, burn surrounding materials, or even cause fire. Ensure tight connections and use cable clamps to secure cables and prevent them from swaying in mobile application. The controller can work with lead-acid battery and lithium battery within its control scope. Battery connection may be wired to one battery or a bank of batteries. The following instructions refer to a singular battery, but it is implied that the battery connection can be made to either one battery or a group of battery bank. Select the system connection cables according to the current density no greater than 5A/mm2. 2.2PV Array Requirements (1)Serial connection(string) of PV modules As the core component of solar system, controller could be suitable for various types of PV modules and maximize converting solar energy into electrical energy. According to the open circuit voltage(Voc) and the maximum power point voltage(Vmpp) of the MPPT controller, the series number of different types PV modules can be calculated. The below table is for reference only. DR1106/2106/3106/1206/2206/3206N-DDB/DDS: System voltage 36cell Voc23V Max. Best 48cell Voc31V Max. Best 54cell Voc34V Max.

(2)Maximum PV array power The MPPT controller has the function of charging current/power-limiting, that is, during the charging process, when the charging current or power exceeds the rated charging current or power, the controller will automatically limit the charging current or power to the rated value, which can effectively protect the charging parts of the controller, and prevent damages to the controller due to the connection of over-specification PV modules. The actual operation of PV array is as follows: Condition1, Actual charging power of PV array Rated charging power of controller Condition2, Actual charging power of PV array Rated charging power of controller When the controller operates under"Condition1" or "Condition2", 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 PV array. WARNING: When the power of PV is not greater than the rated charging power, but the maximum open-circuit voltage of PV array is more than 8 60V(DR**06N-DDB/DDS)/100V(DR**10N-DDB/DDS)(at the lowest environmental temperature), the controller may be damaged. Condition3, Actual charging power of PV array Rated charging power of controller Condition4, Actual charging power of PV array Rate charging current of controller When the controller operates under"Condition 3" or "Condition 4", it will carry out the charging as per the rated current or power. WARNING: When the power of PV is not greater than the rated charging power, but the maximum open-circuit voltage of PV array is more than 60V(DR**06N-DDB/DDS)/100V(DR**10N-DDB/DDS)(at the lowest environmental temperature), the controller may be damaged. According to "Peak Sun Hours diagram", if the power of PV array exceeds the rated charging power of controller, then the charging time as per the rated power will be prolonged, so that more energy can be obtained for charging the battery. However, in the practical application, the maximum power of PV array shall be not greater than 1.5 times the rated charging power of controller. If the maximum power of PV array exceeds the rated charging power of controller too much, it will not only cause the waste of PV modules, but also increase the open-circuit voltage of PV array due to the influence of environmental temperature, which may make the probability of damage to the controller rise. Therefore, it is very important to configure the system reasonably. For the recommended maximum power of PV array for this controller, please refer to the table below: Model DR1106N-DDB/DDS Rated Charge Current 10A Rated Charge Power 130W/12V DR2106N-DDB/DDS 20A 260W/12V DR3106N-DDB/DDS 30A 390W/12V DR1206N-DDB/DDS 10A 130W/12V 260W/24V DR2206N-DDB/DDS 20A 260W/12V 520W/24V DR3206N-DDB/DDS 30A 390W/12V 780W/24V DR2210N-DDB/DDS 20A 260W/12V 520W/24V DR3210N-DDB/DDS 30A 390W/12V 780W/24V At 25 environment temperature.

PV Open Circuit Voltage 46V 60V 92V 100V 9 At minimum operating environment temperature. 2.3Wire Size The wiring and installation methods must conform to all national and local electrical code requirements. PV Wire Size Since PV array output can vary due to the PV module size, connection method or sunlight angle, the minimum wire size can be calculated by the Isc of PV array. Please refer to the value of Isc in the PV module specification. When PV modules are connected in series, the Isc if equal to Isc of PV modules. When PV modules are connected in parallel, the Isc is equal to the sum of the PV modules'Isc. The Isc of the PV array must not exceed the controller's maximum PV input current. Please refer to the table as below: NOTE: All PV modules in a given array are assumed to be identical. Isc=Short circuit current(amps) Voc= Open circuit voltage Model DR1106N-DDB/DDS DR1206N-DDB/DDS DR2106N-DDB/DDS DR2206N-DDB/DDS DR2210N-DDB/DDS DR3106N-DDB/DDS DR3206N-DDB/DDS DR3210N-DDB/DDS Max.

PV wire size 4mm2/12AWG 6mm2/10AWG 10mm2/8AWG CAUTION: When the PV modules connect in series, the open circuit voltage of the PV array must not exceed 46V(DR**06N-DDB/DDS),92V (DR**10N-DDB/DDS). Battery and load wire size The battery and load wire size must conform to the rated current, the reference size as below: Model Rated Charge Current Battery wire size DR1106N-DDB/DDS DR1206N-DDB/DDS 10A 4mm2/12AWG DR2106N-DDB/DDS DR2206N-DDB/DDS 20A 6mm2/10AWG DR2210N-DDB/DDS DR3106N-DDB/DDS DR3206N-DDB/DDS 30A 10mm2/8AWG DR3210N-DDB/DDS 10 CAUTION: The wire size is only for reference. If there is a long distance between the PV array and the controller or between the controller and the battery. Larger size wires can be used to reduce the voltage drop and improve performance. CAUTION: For the battery, the recommended wire size will be selected according to the conditions that its terminals are not connected to any additional inverter. 2.4 Mounting WARNING: Risk of explosion. Never install the controller in a sealed enclose with flooded batteries. Do not install in a confined area where battery gas can accumulate. WARNING:Risk of electric shock. When wiring the solar modules, the PV array can produce a high open circuit voltage, so turn off the breaker before wiring and be careful when wiring. CAUTION: The controller requires at least 150mm of clearance above and below for proper air flow. Ventilation is highly recommended if mounted in an enclosure. Installation steps: 11 Step1: Determine of installation location and heat-dissipation space Determination of installation location: The controller shall be installed in a place with sufficient air flow through the radiators of the controller and minimum clearance of 150mm from the upper and lower edges to ensure natural thermal convection. CAUTION: Ensure that the controller is able to dissipate heat if it's installed in a closed area. If the controller is to be installed in an enclosed box, it is important to ensure reliable heat dissipation through the box. Step2: Wiring Connect the system in the order ofStarter batteryBATT2 Main battery BATT1 PV array in accordance with the above diagram and disconnect the system in the reverse order. CAUTION:The BATT1 and BATT2 must be set at same voltage level, and other situations are not supported for the moment. CAUTION: Follow the above instruction for wiring, otherwise, it may cause the BATT2 system voltage identification error. CAUTION: While wiring the controller do not turn on the breaker or fuse and make sure that the poles of "+" and "-" are connected correctly. CAUTION: A fuse which current is 1.25 to 2 times the rated current of the controller must be installed on the battery side with a distance from the battery not greater than 150mm 12 CAUTION: If an inverter is to be connected to the system, connect the inverter directly to the battery. Step3Grounding DR N series is a common-negative controller, where all the negative terminals of PV array and battery can be grounded simultaneously or any one of the negative will be grounded. However, according to the practical application, all the negative terminals of PV array and battery needn't to be grounded, but the grounding terminal on controller's shell must be grounded, which may effectively shield the electromagnetic interference from the outside, and prevent some electric shock to the human body due to the electrification of the shell. CAUTION:For common-negative systems, such as a motorhome, it is recommended to use a common-negative controller, but if in the common-negative system, some common-negative equipment is used, and the positive electrode is grounded, the controller may be damaged. Step4: Connect the remote temperature sensor cable Temperature sensor (Model:RT-MF58R47K3.81A) Remoter temperature sensor Model:RTS300R47K3.81A Connect the remote temperature sensor cable to the port and place the other end close to the BATT1. CAUTION: If the remote temperature sensor is not connected to the controller, the default temperature for battery charging or discharging is 25 without temperature compensation. Step5: Connect the remote meter MT11 and AES signal of the refrigerator DR1106/2106/3106N-DDB/DDS: 13 DR1206/2206/3206/2210/3210N-DDB/DDS: RS485 Communication cable ModelsCC-RS485-RS485-3.81-4P-150(Included) CC-RS485-RS485-3.81-4P-1000(Optional) CC-RS485-RS485-3.81-4P-2000(Optional) The operation of the remote meter refer to the user manual of MT11 The controller only provides one AES signal control, and the practical consideration is needed for the specific application (Check the "1.5 AES Signal output port instruction" for more information). Step6: Power on the controller Firstly, turn on the BATT2 safety switch and check the BATT2 charging indicator status. then, turn on the BATT1 safety switch and check the BATT1 charging indicator status (Check the "3.

When not in the PV charging state, the controller will not be damaged in case of a short-circuiting in PV array. When the polarity of the PV array is reversed, the controller may not be damaged and can continue to operate normally after the polarity is corrected. NOTE: If the PV array is reverse connected to the controller,1.5 times rated controller power(watts)from the PV array, will damage the controller. Prevents the battery from discharging to the PV module at night. Fully protected against battery reverse polarity; no damage will occur to the battery. Correct the miswire to resume normal operation. NOTE: Limited to the characteristic of lithium battery, when the PV connection is correct either BATT1 or BATT2 battery connection reversed, the controller will be damaged. When the battery voltage reaches the over voltage disconnect voltage, it will automatically stop battery charging to prevent battery damagecaused by over-charging. When the battery voltage reaches the low voltage disconnect voltage, it will automatically stop battery discharging to prevent battery damage caused by over-discharging. (Any controller connected loads will be disconnected. Loads directly connected to the battery will not be affected and may continue to discharge the battery.) The controller can detect the battery temperature through an external temperature sensor.The controller stops working when its temperature exceeds 65 °C and restart to work when its temperature is below 55 °C. When the temperature detected by the optional temperature sensor is lower than the Low Temperature Protection Threshold(LTPT), the controller will stop charging and discharging automatically. When the detected temperature is higher than the LTPT, the controller will be working automatically (The LTPT is 0 °C by default and can be set within the range of 10 ~ -40 °C). The controller is able to detect the temperature inside the controller. The controller stops working when its temperature exceeds 85 °C and restart to work when its temperature is below 75 °C. The internal circuitry of the controller is designed with Transient Voltage Suppressors (TVS) which can only protect against high-voltage surge pulses with less energy. If the controller is to be used in an area with frequent lightning strikes, it is recommended to install an external surge arrester. 4.2 Troubleshooting Faults phenomenon Charging LED indicator off during daytime when sunshine falls on PV modules properly Possible reasons PVarray disconnection Troubleshooting Confirm that PV wire connections are correct and tight. 23 Wire connection is correct,the controller is not working. Battery voltage is lower than 8.5V Please check the voltage of battery. At least 8.5V voltage to activate the controller.

When the temperature declines to be below 55 ºC, the controller will resume. Check whether the battery voltage match with the controller working voltage. Please change to a suitable battery or reset the working voltage. Disconnect the system, and reconnect the BATT2 first, then reconnect BATT1 BATT1 voltage level should be the same as BATT2 4.3 Maintenance The following inspections and maintenance tasks are recommended at least two times per year for best controller performance. Make sure controller firmly installed in a clean and dry ambient. Make sure no block on air-flow around the controller. Clear up any dirt and fragments on radiator. 24 Check all the naked wires to make sure insulation is not damaged for serious solarization, frictional wear, dryness, insects or rats etc. Repair or replace some wires if necessary. Tighten all the terminals. Inspect for loose, broken, or burnt wire connections. Check and confirm that LED or LCD is consistent with required. Pay attention to any troubleshooting or error indication .Take necessary corrective action. Confirm that all the system components are ground connected tightly and correctly. Confirm that all the terminals have no corrosion, insulation damaged, high temperature or burnt/discolored sign, tighten terminal screws to the suggested torque. Check for dirt, nesting insects and corrosion. If so, clear up in time. Check and confirm that lightning arrester is in good condition. Replace a new one in time to avoid damaging of the controller and even other equipments. WARNINGRisk of electric shock! Make sure that all the power is turned off before above operations, and then follow the corresponding inspections and operations. 25 5.
