  • High tracking efficiency: Utilising MPPT (Maximum Power Point Tracking) technology, tracking efficiency reaches up to 99.9%, with a tracking response time of less than 1 ms and a maximum charging conversion efficiency exceeding 98%.It is widely used in off-grid solar PV systems, solar PV and domestic solar systems.
  • Advanced Display: Equipped with a backlit OLED display, it effectively reduces glare in any environment and offers greater clarity than standard LCD screens. It displays various parameters—including voltage, current and battery charge percentage—at a wide viewing angle across a temperature range of -40°C to 70°C, enabling effective fault identification and parameter adjustment, as well as system data monitoring to maintain optimal performance.
  • Premium‌ Material: Featuring a high-quality aluminium heat sink, air cooling and high-temperature derating, it offers greater heat resistance than plastic alternatives. It is equipped with comprehensive charging and discharging protection mechanisms against overvoltage, overcurrent, overload, overtemperature and short circuits. This ensures efficient operation in a wide range of working environments, and comes with a user manual for guidance.
  • Compatible with a wide range of batteries: Supports 12V/24V battery voltages and is compatible with various battery types, including sealed, gel, open-vented, lithium-ion and custom batteries. Users must adjust the parameters accordingly based on the actual battery voltage. Features built-in Bluetooth functionality,allowing settings to be adjusted at any time via a mobile phone.
  • Suitable applications: Suitable for small-scale outdoor systems, not large-scale energy storage systems. Examples include outdoor motorhomes and campervans, surveillance in remote locations, sailing boats, yachts and outdoor workstations. In all these scenarios, the controller must be installed indoors to ensure that components are not exposed and to prevent water from entering the controller.
  • Important notes: Please install the controller in a well-ventilated area, as the heat sinks will become very hot during operation. We recommend fitting a suitable fuse or circuit breaker on the external circuit of the controller. Before connecting or adjusting the controller’s wiring, ensure that the photovoltaic array is disconnected and that the fuse or circuit breaker near the battery terminals is switched off.
