Key benefits — why you need this controller Maximizes solar harvest and battery life: MPPT intelligent tracking optimizes charging to extract more power from panels and reduce charging time, while advanced battery protections extend battery service life. Easy, remote management: Built-in Bluetooth and APP support let you monitor and adjust settings from your phone without accessing the unit directly. Reliable operation in hot environments: A thickened metallic heat-dissipation back panel improves thermal performance so the controller runs stably under high ambient temperatures. Safety-first design: Multiple built-in protections prevent over-current, short circuit, reverse polarity, undervoltage and overcharge, protecting the whole solar system. Core functions and performance MPPT intelligent tracking charging with autofocus and intelligent control for higher charging efficiency and more consistent power delivery. Bluetooth APP remote control for real-time monitoring and configuration from your smartphone. Metal heat-dissipation back panel (thickened) to improve cooling and maintain performance in warm conditions. Comprehensive protection suite: over-current, short circuit, reverse polarity, undervoltage and overcharge protections ensure safe, long-term operation. Compatibility and connectivity Designed for 12V and 24V solar systems—automatic system compatibility simplifies installation and setup. USB outputs allow direct charging of smartphones, tablets and PCs from the solar system, adding convenient device charging without extra converters. What makes this controller stand out Combines MPPT efficiency gains with robust thermal design and full electrical protections, providing a balance of performance, durability and safety. Remote Bluetooth control via mobile APP gives practical, user-friendly system oversight without extra hardware. Practical use cases Off-grid cabin or tiny home: Improve panel-to-battery efficiency, reduce charging time, and monitor system status from your phone. RV, camper or boat: Compact, automatic 12V/24V compatibility with USB charging makes it easy to power and charge devices while mobile. Backup power and remote installations: Robust protections and enhanced heat dissipation allow reliable operation in high-temperature or hard-to-reach locations, reducing maintenance trips. What you get An MPPT solar charge controller with intelligent tracking, Bluetooth APP control, a thick metallic heat-dissipation back panel, USB outputs, and built-in electrical protections—designed for reliable use in 12V and 24V solar systems. Notes on installation and operation Ensure correct system voltage selection (12V or 24V) and proper wiring to benefit from the controller’s protections and MPPT performance. Use the APP to monitor charging status, battery condition and to adjust settings as needed for your specific battery type and solar configuration.
