30A MPPT Solar Charge Controller with Bluetooth and LCD A compact, reliable MPPT charge controller that harvests more solar energy, charges batteries faster, and gives you clear on-site and remote monitoring through an LCD and Bluetooth connection. Key benefits Maximize energy harvest: MPPT technology extracts more power from panels than PWM controllers, charging batteries faster and reducing wasted solar energy. Simplified monitoring and control: Built-in LCD provides at-a-glance system status; Bluetooth lets you view logs, adjust settings, and diagnose performance from a mobile device. Convenient device charging: Dual USB ports allow direct charging of phones, tablets, and small devices from the battery without extra adapters. Flexible system compatibility: Works with 12V and 24V battery banks and supports a wide range of common battery chemistries, simplifying integration into existing setups. Space-saving, durable design: Compact enclosure fits tight spaces and mounts easily in RVs, cabins, boats, or small solar installations; built with quality components for steady regulation and safe, efficient charging. Features and functions 30A MPPT charging capacity suitable for small to medium off-grid systems. LCD display for immediate visibility of voltage, current, battery state, and errors. Bluetooth connectivity for remote monitoring, data transfer, performance logging, and configuration via a mobile app. Dual USB ports for on-site device charging directly from the battery bank. Automatic detection and operation with 12V or 24V systems; supports common battery chemistries. Stable regulation and protective functions designed to protect batteries and connected loads. Compatibility and performance Designed to integrate with typical small solar arrays and battery banks used in recreational and off-grid applications. MPPT algorithm improves charging efficiency in variable sunlight, cold conditions, and when panel voltage exceeds battery voltage. Reliable performance from quality internal components ensures steady output and built-in protections for overcharge, short circuit, and reverse polarity. Practical applications Off-grid cabin, shed, or tiny home: Run LED lighting, keep phones and tablets charged, and maintain battery health with efficient solar charging. RVs and campers: Manage weekend or extended trips with faster charging and mobile monitoring of battery state and system performance. Small home backup and critical loads: Maintain refrigeration, communication devices, or emergency lighting during outages with a compact, easy-to-install controller. Quick setup tips Verify panel and battery compatibility: confirm panel open-circuit voltage and array current match the controller and that the battery chemistry is supported. Connect in the proper sequence: battery first (to allow correct voltage detection), then solar panels; follow the included wiring and safety instructions. Monitor and optimize: use the LCD for immediate checks and Bluetooth/mobile app for logging, status monitoring, and adjusting charge parameters. Secure mounting: install the compact controller in a ventilated, dry location suitable for RVs, boats, or small enclosures. What makes this controller stand out Practical MPPT performance in a compact package for small solar setups. Bluetooth plus on-device LCD gives both local and remote visibility without needing extra hardware. Dual USB ports add everyday convenience by charging devices directly. Built for reliable, safe charging with straightforward installation in common off-grid and mobile use cases.
