The Sungold 100 Amp MPPT Solar Charge Controller is designed to manage and optimize power from solar panels to battery systems. Using Maximum Power Point Tracking (MPPT) technology, it helps maximize energy capture from solar panels with a tracking efficiency of up to 99.9%, improving the efficiency of solar charging.
The controller automatically detects 12V, 24V, 36V, and 48V DC battery systems, making it suitable for a wide range of solar installations. It supports several battery types including lithium, sealed, AGM, and user-defined batteries, providing flexibility for different energy storage setups.
Built-in over-temperature protection and current-limited charging help maintain safe system operation. The controller also supports parallel connections, allowing multiple units to work together and increase the total charging capacity beyond a single controller.
A built-in Bluetooth module allows users to monitor system performance and data through a mobile phone app in real time. The integrated LCD display provides system status information, adjustable parameters, and error codes for easier monitoring and management.
