Features 1??Solar Charge Controller: Adopts MPPT maximum power point tracking technology to realize the maximum energy tracking of solar panels, so that it can be used in any environment. It can quickly and accurately track the maximum power point of the solar cell, obtain the maximum energy of the solar panel in real time, and significantly improve the energy utilization rate of the solar system. 2??MPPT Maximum Power Point Tracking Technology: MPPT tracking efficiency can reach 99%. High efficiency synchronous rectifier circuit structure. Maximum output power is 600W. Input voltage is 17?84V. Output voltage is 10?30V. The maximum efficiency is 97%. The output voltage can be set. 3??LCD Display: Support lithium, lithium iron phosphate and other battery types. Support lithium battery activation. HD LCD display of input voltage, output voltage and output current. Intelligent temperature control, fan heat dissipation. With perfect undervoltage, overtemperature, short circuit, output overcurrent, overload, anti backflow protection mechanism. Adopt aluminum radiator and high temperature derating treatment to ensure reliable and efficient operation in various working environments. 4??Over Temperature Protection: When the internal temperature exceeds 100??, the output power will be reduced. If it up to 110??, the output will be automatically turned off and over temperature will be displayed. When temperature is lower than 85??, it will automatically resume work. When temperature exceeds 65?? or the charging current is greater than 30A, the wind will be automatically turned on, and temperature is lower than 45??, the controller will automatically turn off the fan. 5??Safe To Use: With Intelligent protection against overcurrent, short circuit, inverse, low voltage, and overcharge, this solar charge controller will help you improve the system efficiency safely and prolong the life span of the battery.
