higher tracking efficiency.
◆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.
◆It provides an active charging voltage regulation feature. At battery open circuit or
lithium battery BMS overcharge protection, the controller battery terminal will output
the rated charging voltage value.
◆MPPT tracking efficiency is up to 99.9%.
◆ Due to an advanced digital power technology, the circuit energy conversion efficiency
is as high as 98%.
◆Available in multiple battery types and support charging procedures of various types of
batteries such as lithium battery, colloidal battery, sealed battery, vented battery, lithium
battery, etc.
◆ A current-limited charging mode is available. When the power of solar panel is too
large and the charging current is higher than the rated valve, the controller automatically
reduces the charging power so that the solar panel can operate at the rated charging
current.
◆ Support automatic identification of lead-acid battery voltage.
◆External LCD screen or Bluetooth module can be connected for viewing of equipment
operating data and status, and modification of controller parameters is supported.
◆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.
◆Solar panel short circuit protection, battery open circuit protection and TVS lightening
protection etc.
