The Tracer AN series. Based on common negative design and advanced MPPT control algorithm, with LCD displaying running status, this product is artistic, economical and practical.The limitation function of the charging power and current and reducing charging power function automatic improve the stability which works even connecting oversize PV modules and in high temperature, and increase the professional protection chip for the communication port, further improving the reliability and meeting the different application requirements.With the adaptive three-stage charging mode based on a digital control circuitThis modular solar controller can be widely used for different applications, e.g., Communication base stations, household systems, and field monitoring, etc. The communication port adopts professional protection chip, which can provide 5VDC power supply, and has over-current and short-circuit protection With RS-485 communication bus interface and Modbus communication protocol, it is available to meet various communication requirements in different situationsMonitor and set the parameters via mobile phone APP or PC softwareFull-load operation without any drop in capacity within the range of working environment temperature Advanced MPPT technology, with efficiency no less than 99.5%Advanced MPPT control algorithm to minimize the maximum power point loss rate and loss timeWide MPP operating voltage rangeInternational famous brands of ST and IR's components of high quality and low failure rate are used, which can ensure the product‟s service lifeCompatible with lead-acid and lithium-ion batteriesExtensive electronic protection Charging power and current limitation function Battery temperature compensation function Real-time energy statistics function Overheating power reduction function Multiple load work modes Charge Rated Current:40ASystem Voltage:12V/24V auto workVoltage: 100VConsumption: ≤12mABattery Voltage Range: 8V ~ 32VRS485 communication interface: 5VDC/100mA Grounding type: Negative groundBattery types: Gel battery, Sealed lead-acid battery, Flooded battery, lithium battery, User-defined. The controller connection sequence is Battery--Load--Solar Panel, and discounect the system in the reverse order Solar Panel--Load--Battery CAUTION: While wiring the controller do not close the circuit breaker or fuse and make sure that the leads of "+" and "-" poles are connected correctly.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 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. 4210AN MPPT Solar Controller 12V/24VDC Auto Working100V Max. PV Open Circuit VoltageCompatible with lead-acid and lithium-ion batteriesAdvanced MPPT technology, with efficiency no less than 99.5% MT-50 Wide LCD screen displays the real time operational data and the working status in digital, graphic and textual forms.Basically used for monitoring and setting the controller, it automatically identifies the type, model and relevant parameter data of solar controllers. RS485 USB To RS-485 converter is used to monitor each controller on the network using Solar Station PC software and update the firmware.The length of cable is 1.5m. RTS Acquisition of battery temperature for undertaking temperature compensation of control parameters, the standard length of the cable is 3m.The RTS300R47K3.81A connects to the port on the controller.NOTE: Unplug the RTS, the temperature of battery will be set to a fixed value 25ºC.
