【True 100A Continuous Output for Reliable 24/7 Charging】Many controllers advertise high current ratings but reduce output under heavy loads or elevated temperatures. Featuring a reinforced 1.5X power design, premium-grade components, and advanced thermal management, this 100amp solar charge controller is engineered to continuously deliver a full 100A charging current without throttling. Reliable charging performance helps maximize battery utilization and ensures stable operation for Off Grid Solar Systems, RVs, cabins, farms, workshops, marine applications, telecom equipment, and backup power systems where dependable power is essential.
【250V High-Voltage Input & Up to 5200W Solar Capacity】 Connect more solar panels with greater installation flexibility. Supporting up to 250VDC PV input and up to 5200W solar input power on 48V battery systems, this 250Vdc MPPT Charge Controller allows longer panel strings while reducing cable current, minimizing power loss, and lowering wiring costs. Recommended maximum PV power: 1300W (12V), 2600W (24V), 3900W (36V), and 5200W (48V). Ideal for residential, commercial, RV, and off-grid solar systems requiring higher-voltage PV configurations and expanded solar capacity.
【12V/24V/36V/48V Auto & Wide Battery Compatibility】Compatible with LiFePO4, Lithium-Ion, AGM, Gel, Flooded, Sealed Lead-Acid, and User-Defined batteries. Automatic 12V/24V/36V/48V battery system recognition simplifies installation and setup. Intelligent multi-stage charging helps maximize battery performance and extend service life. Lead-acid batteries support CC Fast Charge, CV Constant Voltage, and CF Float Charge, while the built-in Lithium Battery Activation function helps wake up batteries from low-voltage protection mode. An ideal Solar Charge Controller for Lithium Battery and lead-acid battery systems.
【APP Monitoring, RS485 Modbus & Expandable System Integration】Monitor and manage your solar system with greater visibility and control. Compatible with the SolarMate APP through an optional Bluetooth module, allowing real-time monitoring of PV voltage, charging current, battery voltage, and system status. Equipped with an RJ45 communication port, RS485 communication, standard Modbus protocol, and PC monitoring software support for remote monitoring, parameter configuration, data management, and secondary development. Ideal for expandable solar energy systems and advanced users.
【5 Load Modes, Intelligent Cooling & Full System Protection】Features 5 load modes including Normal, Always-On, Light Control, Light+Timer, and Dual-Period Timer for flexible power management. The intelligent cooling system automatically adjusts fan operation to maintain stable performance under demanding conditions. Comprehensive protection safeguards against reverse polarity, over/under-charge, short circuit, over-current, over-temperature, surge, and reverse current. The large backlit LCD display provides real-time operating status and fault ESF48H100
