Feature:1. Maximum Power Tracking Algorithm: The built in maximum power tracking algorithm can significantly improve the energy utilization efficiency of the photovoltaic system.2. Tracking Technology: Dual peaking or multi peaking tracking technology, when the solar panel is shaded or some of the battery panels are damaged, multiple peaking will appear, and the controller can still accurately track the maximum point power.3. Multiple Protection: Internal over current protection, short circuit protection, open circuit protection, and reverse connection protection are all self recovery, lossless controllers, dual MOS reverse current protection, and low heat generation.4. MPPT: The combination of various tracking algorithms can accurately track the appropriate working point within 1 second, and the MPPT tracking efficiency can be up to 99.9%.5. LCD Display: Equipped with a large screen LCD display, charge and discharge parameters, industrial grade main control chip.Specification:Item Type: Solar Charge ControllerMaterial: PVCPower and Voltage: 650w (12v) 1300w (24v)Product Size: Approx. 16.8 x 9.4 x 4.2cm / 6.6 x 3.7 x 1.7inFeatures: No Power Storage FunctionScope of Application: 12/24v Automatic Adaptation, or 12/24/36/48/60v Manually Set the Appropriate Battery Charging ModeFeatures: 1.
