Advanced MPPT(maximum power point tracking) technology, fast and stable track the Maximum Power Point, tracking accuracy 99.5% maximizing the energy from solar panels to charge your system. 3-stage charging (Bulk, Boost, Float, and Equalization) and temperature compensation increase your battery life and improve your system’s performance.
12V/24V Automatic system voltage, 12V/390W and 24V/780W PV max input power (PV array limited power input function), 30A Max charging current,Synchronous Rectifier Technology, Max 98% transfer efficiency of circuit.
Widely range of Maximum Power Point of PV array, Max PV input Voltage 75V. PV array limited power input function. in theory, no matter how much power of solar panel input, the controller will limited the input power under rated power,to ensure that the controller does not overload operation under any conditions
Normal Mode, Sensor Mode, Timer and Sensor Mode , 3 types battery data(SEL, GEL ,FLD) Built-in operation log, account system working state and humanized LCD displaying, dynamic display operation data and working state.
Excellent digital protect function, Reverse connection, Overcharging, Over-discharging, Overvoltage, Overload, Short circuit, Also professional connector maximum degree avoid damage due to system fault or installation error. 5 years warranty
