ML2430 MPPT Solar Charge Controller Overview The ML2430 is an allinone MPPT solar charge controller designed for offgrid PV systems. It combines advanced maximum power point tracking, flexible battery support, and comprehensive system protection to improve energy harvest and simplify installation. Key features and performance MPPT tracking up to 99.9 percent, with dualpeak and multipeak tracking technology to reliably find the true maximum power point even when panels are partially shaded or have multiple IV peaks. Rated charging current 30A and rated load current 20A. Supports battery systems at 12V and 24V nominal, with automatic battery voltage recognition and a battery voltage operating range of 9 to 35Vdc. Maximum PV open circuit voltage 100Vdc. Supports PV panel configurations such as two panels in series and multiple strings in parallel. Digital power conversion efficiency up to 98 percent. Overall MPPT tracking efficiency greater than 99 percent. Multiple battery charge programs for GEL, sealed, open, and lithium batteries. Temperature compensation automatically adjusts charging parameters to extend battery life. Limited current charging mode prevents charging current from exceeding the rated value when panel power is very . Instantaneous large current startup support for capacitive loads. Builtin overtemperature protection reduces charging current linearly above the set temperature to protect the controller from overheating. TVS lightning protection and comprehensive charge and discharge protections to support stable operation. User interface with LCD screen and LED fault indicators. The LCD displays operating data, status, and fault information and allows parameter adjustment. Historical data storage for up to one year. Standard Modbus protocol support and RS232 communication for system monitoring and integration. Why choose the ML2430 Maximizes energy harvest from PV arrays, especially under partial shading or nonuniform panel conditions. Reduces manual setup and wiring with automatic battery recognition and multiple battery profiles. Protects battery and controller health through temperature compensation, limited current mode, and overtemperature control. Saves space and simplifies system architecture by combining PV, battery, and load control in a single compact unit. Provides flexible monitoring and integration options via RS232 and Modbus. Typical applications Offgrid cabins and small homes: Charge battery banks efficiently from roof or groundmounted PV arrays and power lighting, pumps, and appliances.
