2. Key Features

• Advanced MPPT Algorithm and Adaptive Charging: Features enhanced tracking and response speeds, reducing losses and minimizing downtime. It improves efficiency across various power segments. The adaptive charging includes stages like bulk, boost, equalize, and float, optimizing battery health, lifespan, and overall performance.
• Versatile Battery Compatibility: Supports Lead-acid (Sealed, Gel, Flooded) and Lithium (LiFePO4, Li(NiCoMn)O2) battery types. It ensures correct voltage and current delivery and responds to Battery Management System (BMS) requirements to mitigate risks associated with BMS disconnection, such as potential equipment damage. The controller employs constant voltage output and limited current features for smooth system operation.
• Output Overcurrent Protection: Offers advanced overcurrent protection, quickly detecting and responding to excessive current to prevent solar system damage. It adjusts output in milliseconds to avoid overload and ensure continuous operation.
• Communication Options: View and modify working parameters via MT50 remote meter, APP (WiFi / BLE adapter), or PC software via RS485 interface. The built-in Bluetooth interface (XTRA-N G3 BLE models) offers wireless communication for remote monitoring and parameter adjustment via a smartphone application. The RS485 connection delivers a reliable, hard-wired communication path.
• Enhanced Control: Users can enable/disable the COM port via the LCD screen to conserve energy, reducing energy consumption by cutting the power used for communication operations.
• Ultra-quiet & Low Power Design: Designed for efficiency with low power consumption (≤30mA/12V, ≤16mA/24V, ≤13mA/48V). Disabling communication features further reduces consumption (typically <8mA/12V, <6mA/24V, <5mA/48V), boosting standby time by over 70% and ensuring system reliability when power is limited. Crafted for ultra-quiet operation, it's ideal for environments where noise is a concern, seamlessly fitting into indoor settings.
• Real-time Energy Statistics: Provides real-time energy data for effective system management.
• Common Negative Grounding: Designed for wide application in communication base stations, household systems, street lighting, field monitoring, and RV solar systems.
