Key benefits Reliable operation in hot environments: thickened metallic heat-dissipation back panel improves thermal transfer so the controller can operate normally at higher ambient temperatures. Higher energy harvest and smarter charging: MPPT intelligent tracking charging with automatic tracking maximizes power extraction from the solar array and optimizes battery charging. Remote monitoring and control: Bluetooth connectivity with downloadable app lets you monitor status and adjust settings from your phone. Longer battery life and system protection: multiple built-in protections reduce risk of damage and help extend battery and system lifetime. Main features Thermal design: metallic, thickened heat-dissipation back panel for improved cooling and stable performance under heat stress. MPPT intelligent tracking charging: fast, accurate maximum power point tracking and intelligent charge control for better charging efficiency. Bluetooth app control: supports downloadable app and Bluetooth remote control for real-time monitoring and configuration. Safety protections: integrated over-current, short-circuit, reverse polarity, undervoltage, and overcharge protection to safeguard the solar system and battery. System compatibility: designed for 12V and 24V solar systems. USB outputs: convenient USB ports for charging smartphones, tablets and PCs directly from the solar system. What this means for you Improved system efficiency and more usable energy from the same solar array thanks to MPPT tracking. Reduced maintenance and fewer heat-related failures because of the enhanced metallic cooling panel. Easier system management and troubleshooting with Bluetooth app access. Greater peace of mind from comprehensive electrical protections that help prevent damage and extend battery life. Practical applications Off-grid cabins and tiny homes: reliably charge batteries and power small devices while maintaining battery health and handling warm cabin temperatures. Recreational vehicles and boats: maximize energy from rooftop panels, monitor charging remotely via Bluetooth, and charge phones or tablets through the built-in USB ports. Remote monitoring stations or backup power systems: stable operation in hot, exposed locations, robust protections to preserve batteries, and remote oversight without returning to site.
