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 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.
Optional built-in Bluetooth function, which can view the running data
and status of equipment and support the change of controller
parameters.
Optional built-in CAN function, which can view the running data and
status of equipment and support the change of controller parameters.
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 lightning protection, etc.
