30A Solar Panel Charge Controller Regulator for 12V/24V Lead/Lithium Batteries. Intelligent charge controller with LCD screen and dual USB ports, on/off timer setting.

General Description This 30A charge controller is designed for 12V and 24V battery systems, offering 4-stage PWM charging (Boost, ABS, Equalization, Float). It uses a power MOSFET as an electronic switch, with no mechanical parts, and is equipped with an industrial-grade STM 8 microprocessor to extend battery life. This controller is compatible with lithium-ion, lithium iron phosphate, and lead-acid batteries (open, AGM, GEL), and features a backlit LCD screen to display charge and discharge parameters. Technical Specifications System Voltage: 12V/24V automatic Charging Current: 30A Maximum Input Power: 360W/24V (12V system); 720W/48V (24V system) USB Output: Dual USB output, 5V/2.5A Equalization: 12.6V (default) Discharge Reconnect Voltage: 10.5V (default) Discharge Cutoff Voltage: 9V (default) Self-Consumption: <10mA Operating Temperature: -35~60°C Dimensions: 133.5mm x 70mm x 35mm Weight: Not specified Compatibility and Accessories Compatible with 3 types of batteries: Lead-acid battery (12V/24V) Lithium-ion battery (3 strings of 11.1V lithium batteries) Lithium iron phosphate battery (4 strings of 12.8V) Installation Connect the battery to the charge controller (positive and negative) Connect the photovoltaic module to the controller (positive and negative) Connect the load to the charge controller (positive and negative) Note: The reverse order applies during disassembly to avoid damaging the controller. Operation: The controller automatically manages the operation of the solar panel and battery in the solar system. It automatically shuts down when the battery voltage drops below 8V, rendering the LCD screen unavailable.
