BL916MPPT Boost type solar charging controller

(Designed specifically for charging electric scooters)

• • Model: BL916 MPPT
  • Specially designed for low-power scenarios:
  • Core adaptation: For the replenishment needs of electric vehicles, RVs, and outdoor portable battery packs, it supports low-voltage solar panels to boost and charge high-voltage batteries.
  • Input/output characteristics:
  • Solar panel input:
  • 18V solar panel → output compatible with 24V/36V battery (boost charging);
  • 36V solar panel → output compatible with 48V/60V/72V battery (direct boost matching high-voltage battery system);
  • Battery startup and repair: Supports 0V battery activation startup, built-in pulse repair function, awakens deeply depleted batteries and optimizes cycle life.
  • Compatibility of battery types:
  • All types supported: colloidal batteries, lead-acid batteries, lithium iron phosphate batteries, lithium batteries
  • Multi mode communication and convenient management:
  • Bluetooth version: Real time monitoring of charging status, voltage/current data, fault warning, and parameter adjustment through a mobile app (local wireless direct connection, instant control, suitable for short distance operation);
  • GPRS version in China: 4G network remote control (requires SIM card)
  • WIFI/Bluetooth dual-mode model: Balancing local Bluetooth connection and LAN WIFI control,
  • Support PC port management (viewing device status, exporting historical data, and remotely configuring parameters through a web interface), suitable for remote areas or unmanned mobile power scenarios;
  • Output in 6 different time periods throughout the day: customizable charging power for 6 time periods within 24 hours (such as full power fast charging during high light periods during the day and low-power maintenance mode at night), adapted to changes in light conditions and battery charging stages, improving efficiency and protecting the battery.
  • Advantages of MPPT Boost Technology:
  • Conversion efficiency ≥ 98%, real-time tracking of the maximum power point of the solar panel, maintaining efficient energy capture even in low light or voltage fluctuation scenarios;
  • Built in boost circuit, without the need for additional converters, seamlessly converts low voltage input to high voltage output, simplifying system installation complexity.
  • Multiple security protections:
  • Overcharge/overdischarge/short circuit/reverse connection protection, combined with over temperature automatic current limiting function, to ensure the safety of the battery and controller;
  • Optimize circuit design for frequent vibration scenarios of electric vehicles to enhance anti-interference ability and stability.
