Expected delivery is 10-15 days.International Shipping 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 98%; full-load efficiency can reach 97%. Combination of Various Tracking Algorithm: JN-MPPT series can track the maximum power point quickly. Four Sections of Charging Ways: MPPT charge, equalizing charge, improving charge and floating charge. 12V/24V/48V Automatic Identification: Users can set the voltage according to actual need. 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 75°C, charging current is limited to half of the rated current; when reaches 90°C 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.
