Features: * High-definition LCD display: Large-size high-definition display, displaying power generation, photovoltaic status, battery status, charging status, system operation status and other information, to fully grasp the power generation information. * Built-in lithium battery activation function: when the lithium battery is discharged to the over-discharge protection value, the lithium battery will lock itself, and the outside world cannot charge and discharge it. In this way, for the user, the system cannot be used normally because it does not have a lithium battery activation function. * Current focusing MPPT charging, uninterrupted detection of charging process, two-way focus tracking. * Compatible with: lead-acid battery, colloidal battery, lithium iron phosphate, ternary lithium battery and user-defined. * Support: lead-acid battery 12V/24V/36V/48V adjustable. * Support: Gel battery 12V/24V/36V/48V adjustable. * Support: LiFePO4 battery 2-18 series adjustable. * Support: Ternary lithium battery 2-18 series adjustable. * Support: Lead acid/Gel battery 12V-48V adjustable. Maximum supported photovoltaic input voltage 180V. Specification: Charging mode: MPPT automatic maximum power tracking With lithium battery activation function: there is charging voltage (activating lithium battery) when there is photovoltaic input, and it can be used without battery DC output Photovoltaic minimum voltage to start charging: photovoltaic voltage is greater than battery voltage +3V (low current charging is possible on rainy days) Photovoltaic charging current adjustable: 30A:0-30A 40A:0-40A 50A:0-50A 60A:0-60A DC current output (street light function): 30A,40A:DC continuous output 25A 50A,60A:DC continuous output 60A Temperature compensation: automatically compensate charging voltage and current according to battery temperature to extend battery life LCD touch button: LCD display: (power generation/photovoltaic voltage/battery voltage/charging current/power/operating status) Settings: (battery type, charging current, factory reset), Chinese and English display 485 communication: 8-pin RS485 communication interface (can query operating status and settings) Protection function: photovoltaic array short circuit, overvoltage, overcurrent reverse connection protection, battery overcharge, reverse connection protection, undervoltage protection Packing included: 1 * Solar Controller
