MPPT solar charge controller with Bluetooth app — combines smarter charging, broad compatibility, robust cooling, and full protection to keep your 12V/24V solar system efficient and reliable. Key benefits Higher charging efficiency: MPPT intelligent tracking charging/autofocus maximizes energy harvest from solar panels so batteries charge faster and use more of the available solar power. Remote monitoring and control: download the app and use Bluetooth remote control to check status, change settings, and monitor charging performance from your phone or tablet. Universal compatibility: works with both 12V and 24V solar systems and includes USB outputs so you can charge smartphones, tablets and PCs directly from your solar setup. Reliable thermal management: metallic, thickened heat-dissipation back panel improves cooling and lets the controller operate normally in high ambient temperatures. Full protection suite: built-in over-current, short-circuit, reverse-polarity, undervoltage and overcharge protections protect your system and help extend battery life. What it solves Stops wasted solar energy by using MPPT tracking to follow optimal panel output. Removes the guesswork of system monitoring with Bluetooth app access for real-time data and adjustments. Prevents common faults that can damage batteries and electronics by automatically applying multiple protective measures. Keeps the controller stable in hot locations with a reinforced heat-dissipation design. Key attributes Function: MPPT intelligent tracking charging/autofocus with intelligent control and Bluetooth app support. Compatibility: Designed for 12V and 24V solar systems; USB outputs for charging consumer devices. Material and cooling: Thickened metallic heat-dissipation back panel for improved thermal performance. Performance and safety: Improves system efficiency and extends battery life; includes over-current, short-circuit, reverse-polarity, undervoltage and overcharge protections. Typical use scenarios Off-grid cabin or small home solar system: Use the controller to maximize panel output, protect the battery bank, and monitor charging remotely via the app. RV or campervan: Manage a 12V/24V onboard solar setup, charge laptops and phones via USB, and monitor charging performance while on the road. Portable or temporary installations (camping, work sites): Rugged thermal design and comprehensive protections let the controller run reliably in hot, variable conditions while powering and charging devices. Technical reminders Compatible with 12V and 24V systems only. USB outputs are provided for direct device charging. Ensure proper wiring and follow installation guidelines to maintain protections like reverse-polarity and short-circuit prevention. Reliable, efficient solar charging with app-enabled control, durable cooling, and the safety features needed to protect your system and extend battery life.
