SolaMr MPPT 20A Solar Charge Controller 12V/24V Solar Panel Regulator Smart Identification Voltage Controller with LCD Display, Temperature Sensor - 30A

• Innovative Maximum Power Point Tracking Technology (MPPT) with maximum power point tracking efficiency >99.9%, Full digital control technology, charging conversion efficiency up to 98%.
• LCD screen dynamically displays the operating data and working status of the device, external temperature sensor for more accurate temperature compensation.
• Use the standard Modbus communication protocol based on RS-485 communication bus to maximize the communication needs of different occasions.
• Built-in over-temperature protection mechanism, when the temperature exceeds the set value, the charging current decreases linearly with temperature, thereby reducing the temperature rise of the controller and avoiding high temperature damage of the controller.
• Current limiting charging mode, when the solar panel power is too large and the charging current is greater than the rated current, the controller automatically reduces the charging power and operates at the rated charging current.
