MPPT110D Bluetooth Solar Charge Controller A compact, intelligent MPPT solar charge controller with Bluetooth monitoring and automatic 12V/24V system detection. Designed to improve charging efficiency, simplify installation, and provide convenient system monitoring from a mobile device. Key benefits Improved solar harvesting: MPPT tracking maximizes energy from panels under changing light conditions to charge batteries more effectively than basic controllers. Easy system setup: Automatic 12V and 24V detection removes the need to manually set system voltage, reducing installation errors. Onboard Bluetooth monitoring: View charging status, voltage, current, and basic historical data from a smartphone for setup and troubleshooting without opening enclosures. Spacesaving design: Compact form factor fits into small control compartments or equipment boxes. Reliable operation: Designed for continuous use in offgrid and mobile installations where consistent battery charging is required. Main features and performance Model: MPPT110D Bluetooth Function: Maximum Power Point Tracking charge regulation with Bluetooth monitoring System compatibility: Automatically supports 12 volt and 24 volt battery systems and standard PV panel arrays sized for those systems Ease of use: Plugandplay voltage autodetection combined with a simple Bluetooth interface for commissioning and status checks Mounting and layout: Compact controller size allows flexible mounting near batteries or within small enclosures for reduced wiring losses Practical applications Recreational vehicles and caravans: Keep service batteries charged during travel and while boondocking, with easy monitoring from a phone without entering the vehicle control area. Offgrid small cabins and sheds: Improve daily battery charge from modest solar arrays, helping power lights, pumps, and electronics reliably. Marine and small boat systems: Manage battery charging from deckmounted panels while minimizing space and simplifying access to charging data. Installation tips Mount controller in a ventilated location away from direct weather exposure. Place controller close to the battery bank to minimize voltage drop and use appropriately sized cable for the system current. Use the Bluetooth interface at initial setup to confirm system voltage selection and verify charge current and battery voltage readings. What this product solves Reduces wasted PV energy compared to nonMPPT controllers Simplifies voltage configuration and monitoring for 12V and 24V battery systems Provides accessible system information without opening electrical enclosures or using additional display hardware This MPPT110D Bluetooth controller is a practical choice when you need a compact MPPT regulator with automatic 12V and 24V support and convenient Bluetooth monitoring for offgrid, mobile, or small residential solar charging applications.
