This solar controller adopts LCD display, you can see the input voltage, output voltage, output current and temperature clearly at a glance. Maximum power point tracking technology, MPPT tracking efficiency up to 99%. Intelligent temperature control, fan cooling. Support lead-acid battery, ternary lithium battery, lithium phosphate and other battery types.

Features:
All- Housing: Using heat sink, with nice heat dissipation effect, to ensure reliable and efficient operation under various working environments.
LCD Display: Adopts LCD display, you can see the input voltage, output voltage, output current and temperature clearly at a glance.
MPPT Technology: Maximum power point tracking technology, MPPT tracking efficiency up to 99%, compared to the PWM algorithm, the efficiency increased by 15%-20%.
Output Voltage Adjustable: Output voltage can be set between 10-30V, button step 0.1V.
Synchronous Rectification: The circuit adopts high efficiency synchronous rectification to circuit structure. The use of extremely low on-state resistance of high-frequency switching MOSFET instead of the traditional rectifier diode, greatly improving the efficiency of the converter, reduce the temperature of the entire machine housing, to achieve the smallest housing to achieve greater power output. 
Cooling Fan: Intelligent temperature control, fan cooling. When the internal ambient temperature of MPPT controller exceeds 65℃ or the charging current is greater than 30A, MPPT controller will automatically turn on the fan. When the internal temperature of MPPT controller is lower than 45℃, MPPT controller will automatically turn off the fan.
Perfect Protecting Mechanism: With perfect protections mechanism for under voltage, over temperature, short circuit, output over current, over load, backflow preventions, etc.
Adapt to Various Batteries: Support lead-acid battery, ternary lithium battery, lithium phosphate and other battery types.
