Tracer AN series controller, based on multiphase synchronous rectification technology (MSRT) and advanced MPPT control algorithm, with dual-core processor architecture and common negative design, has the features of high response speed, high reliability, and high industrial standard. MSRT can ensure very high conversion efficiency in any charge power, which sharply improves the energy efficiency of solar system; Advanced MPPT control algorithm minimize the maximum power point loss rate and loss time, to ensure the tracking efficiency,corresponding speed as well as high conversion efficiency under high or low power, so that in any situation, Tracer AN products can rapidly track the maximum power point(MPP) of PV array to obtain the maximum energy of the panel. The load, utility or generator auto-control relays make it easy to compose the hybrid power system. So that can be widely used for various applications, e.g.solar RV, household system and field monitoring, etc. FEATURE Advanced MPPT technology & ultra-fast tracking speed, with tracking efficiency no less than 99.5% and will minimize the MPP loss rate and loss time, Maximum DC/DC transfer efficiency is as high as 98.6% , full load efficiency is up to 98%The accuracy of the recognition and tracking at the highest point of multiple-peaks MPP.Auto control system to limit the charging power & current go over the rated value.

DIAGRAM OF CONNECTION MOUNTING CAUTION Risk of explosion! Never install the controller in a sealed enclose withflooded batteries! Do not install in a confined area where battery gas can accumulate.Risk of electric shock! The solar array high voltage can cause serious shock or injury. Make use of fuses/breaker or cover the entire solar array, prior to performing any work on change controller.The controller requires at least 150mm of clearance above and below for proper air flow. Ventilation is highly recommended if mounted in an enclosure.While wiring the controller do not turn on the 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 batteryIf the PV array is reverse connected to the controller,1.5 times rated controller power (watts)from the PV array, will damage the controller.NOTE: When the PV modules are in series, ensure that the open-circuit voltage of the PV array does not exceed the "Max. PV open-circuit voltage" rating. Otherwise the controller may be damaged. (VOC Don't exceed 92V!) How to program for Lithium Battery？ Via PC (Accessories needed：RS485),Software-- look for in the manual Would the unit be damaged if the battery polarity is reversed? It is required to connect the battery first, if the battery polarity is reversed in this step, the controller has the protection and would not be damaged. But if the user connects the PV first and then, unfortunately, connects the battery polarity reversed, the controller would be damaged. This is caused by lithium battery characteristics.
