The Tracer Dream 200V Series controller owns a self-adaptive three-stage charging mode based on a digital control circuit. This function can effectively prolong the battery's lifespan and significantly improve the system's performance.Limiting the charging power and reducing charging power functions ensure the system stable with over PV modules in high temperature environment.With comprehensive electronic fault self-detecting functions and powerful electronic protection functions built inside the controller, component damage caused by installation errors or system failures can be avoided to the greatest extent possible.The utility/generator dry contact to connect external devices conveniently composes a hybrid power system easily.The isolated RS485 port with standard MODBUS communication protocol and 5V power supply is easy to expand the application and connect the external Bluetooth/WiFi module. The controller can be widely used for various applications, e.g., solar RV, household s...

 With the advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point.Advanced MPPT technology, with efficiency no less than 99.5% Maximum DC/DC conversion efficiency of 98% Ultra-fast tracking speed and guaranteed tracking efficiency Advanced MPPT control algorithm to minimize the MPP loss rate and loss time Wide MPP operating voltage range Limit charging power & current over rated range.When the solar panel power exceeds a certain level and the charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level. Support the lead-acid,gel,flooded with the needed Temp. compensation and support lithium batteries starting from solar panel Real-time working record function Load dry contact to control the external load swi...
