MPPT Solar Charge Controller
◆ With the advanced dual-peak or 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.
◆ A built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM method.
◆ A combination of multiple tracking algorithms enables accurate tracking of the optimum working point on the I-V curve in an extremely short time.
◆ The product boasts an optimum MPPT tracking efficiency of up to 99.9%.
◆ Advanced digital power supply technologies raise the circuit's energy conversion efficiency to as high as 98%.
◆ Charging program options are available for different types of batteries including gel batteries, sealed batteries, open batteries, lithium batteries, etc.
◆ The controller features a limited current charging mode. When the solar panel power exceeds a certain level and the charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.
◆ Instantaneous large current startup of capacitive loads is supported.
◆ Automatic recognition of battery voltage is supported.
◆ LED fault indicators and an LCD screen which can display abnormality information help 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 with which users can not only check device operating data and statuses, but also modify controller parameters.
◆ The controller supports standard Modbus protocol, fulfilling the communication needs of various occasions.
◆ The controller employs a built-in over-temperature protection mechanism. When temperature surpasses the set value, the charging current will decline in linear proportion to the temperature so as to curb the temperature rise of the controller, effectively keeping the controller from being damaged by overheat.
◆ Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters in order to extend the battery's service life.
◆ TVS lighting protection
◆ PowerCatcher maximum power point tracking technology allows the controller to track the maximum power point of solar panels even in a complex environment. Compared with the traditional MPPT tracking technology, it boasts faster response speed and 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.
