• Advanced multi-peak tracking technology. When the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point.

• Built-in maximum power point tracking (MPPT) algorithm significantly increases energy utilization efficiency of the photovoltaic system, (about 15% to 20% higher than traditional PWM charging.)

• 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 allows up to 99.9% efficiency. • Uses advanced digital power technology to increase the circuit energy conversion efficiency to as high as 98%.

• Supports multiple battery chemistries, including lithium, sealed, vented, AGM, and flooded Lead Acid.

• Current-limited charging mode. When the power of solar panel is too large and the charging current is higher than the rated value, the controller automatically reduces the charging power so that the solar panel can operate at the rated charging current.

• Supports automatic identification of lead-acid battery voltage.

• Features LED fault indicators and an LCD screen, which can display abnormal information, helps users to quickly identify system faults.

• Historical data storage function is available, and data can be stored for up to a year

• The controller is equipped with an LCD screen allowing users to easily check device operation and statuses and modify controller parameters

• Supports standard Modbus protocol to meet different options.

• Built-in over-temperature protection ensures that when temperature exceeds the set value of the device, the charging current decreases linearly with the temperature, which reduces an increase in the controller’s temperature, avoiding 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 transient protection.
