SRNE 50A MPPT Solar Charge Controller for RV, Boat, Off-Grid System - High Efficiency 12V/24V Auto-Switching with LCD Display | Perfect for Solar Panel Battery Charging, Home & Outdoor Power Solutions

Product Description

• PowerCatcher maximum power point tracking technology allows the controller to track the maximum power point of solar panels even in a complex environment. Compared with the traditional MPPT tracking technology, it boasts faster response speed and higher tracking efficiency.
• Built-in maximum power point tracking (MPPT) algorithm significantly increases energy utilization efficiency of the PV system, which is about 15% to 20% higher than traditional PWM charging.
• Active charging voltage regulation: Battery open circuit & lithium battery BMS overcharge protection.
• MPPT tracking efficiency up to 99.9%.
• Compatible with lithium, flooded, and sealed/AGM batteries.
• Current-limited charging mode: the controller automatically reduces the charging power so that the solar panel can operate at the rated charging current.
• Automatic identification of lead-acid battery voltage.
• Optional external LCD screen or Bluetooth module can be connected for remote viewing & parameter adjustment. 
• Supports standard Modbus protocol to meet communication needs for various applications. 
• Built-in over-temperature protection.
• Max Power of PV: 660 Watts/12V  1320 Watts/24V
• Max Voltage of PV: 100V
