Compact 30A MPPT Solar Charge Controller with Mobile Phone App Control and LED Display Overview This 30A MPPT solar charge controller is part of a family available in 20, 30, 40, 50, and 60A ratings and supports both 12V and 24V systems. It combines maximum power point tracking for efficient charging with mobile phone app control and ondevice LED display for realtime system monitoring and parameter adjustment. Key benefits Increase usable solar output: MPPT tracking extracts more power from PV panels than traditional PWM controllers, improving daily charge delivered to the battery. Remote monitoring and control: builtin Bluetooth connection and mobile phone app let you view system data and change settings without accessing the controller directly. Immediate system insight: front LED display provides realtime readouts for voltage, charging current, and operating state so you can quickly confirm system health. Flexible deployment: automatic 12V and 24V detection simplifies installation and avoids manual configuration errors. Scalable options: choose the capacity that matches your system from 20, 30, 40, 50, or 60A models. Functions and performance MPPT charging algorithm optimizes charging current from solar panels to the battery bank. Realtime data monitoring through LED display and mobile app covers key electrical parameters for fast diagnostic and performance checks. Designed to support continuous charging current up to 30A for this model, with higher capacities available in the product line. Compatibility and fit Works with 12V and 24V battery systems and standard PV arrays sized to match the controller rating. Compatible with common offgrid and vehicle solar setups; verify panel voltage and current do not exceed controller specifications when selecting a model. Design and build Compact form factor suitable for mounting in small enclosures or on flat surfaces. User interface combines a simple LED display for onsite viewing and mobile app access for remote monitoring and configuration. Typical use scenarios Weekend RV or camper setup: Manage rooftop panels and a 12V battery bank while monitoring charge status from a mobile phone during travel or at camp. Remote cabin or shed: Pair with a small PV array and 12V or 24V battery bank to keep batteries topped up and check performance from a distance using the app. Small offgrid system or backup power: Monitor charging current and panel output in real time while scaling controller capacity to match system needs. What to check before Confirm system voltage is 12V or 24V and select the controller current rating that matches expected PV array output and battery charging requirements. Ensure panel open circuit voltage and short circuit current fall within the controller limits for safe operation. Available models Controller series available in 20A, 30A, 40A, 50A, and 60A versions. This listing describes the 30A model. This MPPT solar charge controller is intended for users who need reliable, monitored solar charging with flexible installation options and easy mobile access to system data.
