· Advanced dual-peak or multi-peak tracking technology.
· Built-in algorithm for maximum power point tracking to significantly improve the energy utilization efficiency of photovoltaic systems.
· Charging efficiency 15%-20% higher than traditional PWM solar charge controllers.
· Combination of multiple tracking algorithms that can track the optimum working point of I-V curve accurately in a very short time.
· MPPT efficiency can be as high as 99.9%
· Advanced digital power supply technologies to raise the circuit’s energy conversion efficiency to as high as 98%.
· Charging program options for different types of batteries including gel batteries, sealed batteries, open batteries, lithium batteries, etc.
· Current-limiting charging mode. When the power of a solar panel is too large, and the charging current is greater than rated current, the solar charge controller automatically reduces charging power to bring the charging current to the rated level.
· Instantaneous large current startup of capacitive loads.
· Automatic identification of battery voltage.
· LED fault indicators and an LCD screen to display abnormality information to help users quickly identify system failures.
· Supports data storage for up to a year.
· LCD screen display to enable users to view device operation data and status and modify controller parameters.
· Standard Modbus protocol to meet communication needs for various occasions.
· Built-in mechanism for over-temperature protection. When the temperature exceeds the set value, the charging current falls linearly with temperature, therefore slowing down the rise of controller temperature and avoiding controller damage from overheating.
· Temperature compensation function to automatically adjust charging and discharging parameters to extend battery service life.
· TVS lightning protection.
