This 30A charge controller is compatible with 12V and 24V systems. It features a fully 4-stage PWM charging process (Boost, ABS, Equalization, Float). The power MOSFET is used as an electronic switch with no mechanical switches, and it includes an industrial-grade STM8 microprocessor to help extend battery life. The controller has a backlit LCD display showing charging and discharging parameters for PV, battery, and charge. It includes dual USB outputs, providing up to 5V and 2.5A for charging electronic devices.This solar controller works with lithium-ion, lithium iron phosphate, and lead-acid batteries (OPEN, AGM, GEL), and supports multiple load timers (load must be DC). It automatically detects day and night and has wide applicability. To protect battery life, the controller will automatically shut down when the battery voltage drops below 8V.The controller offers several protections: Dual MOSFET Reverse Current, Overheat, Under-discharge, Undervoltage, Short Circuit, Open Circuit, Overload, and Power Off Memory Protection. It is suitable for use in homes, industry, and commercial applications.Battery compatibility:- B1: Lead-acid battery (12V/24V automatic)- B2: Lithium-ion battery (3 strings of 11.1V lithium batteries, factory default)- B3: Lithium iron phosphate battery (4 strings of 12.8V)System voltage: 12V/24V automatic Charging current: 30A Maximum input power and voltage: - 360W / 24V for 12V systems - 720W / 48V for 24V systems USB output: Dual USB output, 5V / 2.5A Equalization voltage: 12.6V (default) Discharge reconnect voltage: 10.5V (default) Discharge stop voltage: 9V (default) Turn on/off light voltage: Solar panel 8V Self-consumption:
