MPPT Solar Charge Controller 10A 20A 30A 40A with LCD Display, Auto 12V 24V Product summary This MPPT solar charge controller uses a common negative design and an advanced MPPT control algorithm to extract maximum energy from PV modules. It features an LCD that displays operating status and system data, supports automatic 12V or 24V battery systems, and is available in 10A, 20A, 30A, and 40A models. The controller improves energy harvest compared with PWM controllers while providing flexible protection and communication options for professional and residential solar setups. Key benefits Higher energy yield: Advanced MPPT algorithm reduces maximum power point loss and tracking time, increasing energy utilization compared with PWM charging methods by about 10 to 30 percent. Fast and accurate tracking: Ultrafast tracking speed and improved algorithm ensure the PV array operates near the true maximum power point even under changing irradiation or partial shading. Stable operation with oversized arrays: Builtin charging power and current limitation plus automatic power reduction at temperatures maintain stability when PV input exceeds nominal limits. Flexible battery support: Compatible with leadacid and lithiumion battery chemistries and includes battery temperature compensation for correct charging behavior. Easy monitoring and control: LCD shows realtime status and energy statistics. Parameters can be set and monitored via mobile phone app or PC software. RS485 interface and Modbus protocol enable integration with external monitoring systems. Reliable communications and protection: Professional protection chip for the communication port and multiple protection routines increase reliability in demanding installations. Features and functions Models available: 10A, 20A, 30A, 40A. System voltage: Automatic detection and support for 12V and 24V battery systems. MPPT efficiency: MPPT control efficiency no less than 99.5 percent. Tracking performance: Ultrafast tracking speed, wide MPP operating voltage range, and accurate recognition of multiplepeak maximum power points. Power management: Charging power and current limitation functions; automatic reduction of charging power to prevent overheating and to stabilize operation with oversize PV modules or ambient temperatures. Battery support: Compatible with common leadacid types and lithiumion battery packs; battery temperature compensation function included. Data and monitoring: Realtime energy statistics, LCD display of running status and parameters, remote monitoring and parameter configuration via mobile app or PC software. Communication: RS485 communication bus and Modbus protocol for integration with solar monitoring or automation systems. Load control: Multiple load working modes to support lighting, pump, and other load scenarios. Operational reliability: Designed for fullload operation across the rated working temperature range without loss of capacity; enhanced communication port protection and robust control logic. Typical applications Offgrid residential and cabin systems: Charge 12V or 24V battery banks from rooftop PV panels while monitoring energy production and battery state via LCD or remote software. Recreational vehicles and boats: Manage solar charging for leisure batteries with compact controllers in 10A to 40A sizes depending on array and battery capacity. Remote lighting and pump systems: Drive lighting loads or water pumps with programmable load modes and stable operation under variable sunlight and temperature conditions.
