20A 12V/24V/48V MPPT Solar Charge Controller Automatic Identification 150V Input With USB-RS232 Cabl

Features: -Advanced Maximum Power Point Tracking(MPPT) Technology: Tracking efficiency not less than 99.5% 15%-20% higher than common PWM algorithm. -High Quality Components and Advanced Power Conversion Circuit: The max. conversion efficiency can reach more than 96%; full-load efficiency can reach 97%. -Combination of Various Tracking Algorithm: JN-MPPT series can track the maximum power point quickly. -With Current-limiting Charging Mode: When the charging current exceeds the rated current, the controller will limit the charging current to the rated current charge. -With Internal Temperature Detection Function: When reaches 75C, charging current is limited to half of the rated current; when reaches 90C charging and load are shut off. -Multiple Protection: With over charge/over discharge/over temperature/over load and reverse connection protection. The battery temperature compensation function.
