HQST 20A 12/24V MPPT Solar Charge Controller, Compatible with Sealed, Gel, Flooded, Lithium, User Defined Batteries

Make sure this fitsby entering your model number.
A built-in maximum power point tracking (MPPT) algorithm can significantly increase energy utilization efficiency of the photovoltaic system, which is about 15% to 20% higher than traditional PWM charging.
Support standard Modbus protocol to meet communication needs in different occasions
Built-in over-temperature protection mechanism ensures that when temperature exceeds the set value of the device, the charging current decreases linearly with the temperature, thereby reducing the temperature rise of controller and avoiding high temperature damage
Temperature compensation and automatic adjustment of charge and discharge parameters help to improve battery life.
Support automatic identification of lead-acid battery voltage. External LCD screen can be connected for viewing of equipment operating data and status, and modification of controller parameters is supported.
