BL915 Solar Charging Controller

• • Model: BL915
  • Input characteristics:
  • Charging current range: 10A – 60A (wide range suitable for small to medium power solar panels)
  • Output characteristics:
  • Output current: 5A-15A (stable current control, compatible with charging requirements of different capacity batteries)
  • Compatible with battery voltage:
  • Basic mode: 12V/24V (compatible with conventional low-voltage battery systems)
  • Compatibility of battery types:
  • Supports all types of batteries: colloidal batteries, lead-acid batteries, lithium iron phosphate batteries, lithium batteries
  • Breakthrough battery management technology:
  • 0V battery activation and repair: supports zero voltage battery startup, unique battery repair function can wake up deeply depleted batteries, optimizes battery cycle life through pulse repair algorithm, and solves the problem that traditional controllers cannot handle 0V batteries;
  • Charging and discharging at high current: Supports bidirectional power flow, allowing solar panels to directly supply power to the load while charging the battery, maximizing energy efficiency and reducing the need for battery capacity redundancy.
  • Intelligent control and communication mode (only supported in 12V/24V battery mode):
  • Multi mode communication model:
  • 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 home scenarios);
  • WIFI/Bluetooth dual-mode model: supports Bluetooth local operation and WIFI LAN connection, compatible with PC port management (device configuration, historical data export, multi device cluster monitoring through web interface, suitable for industrial level centralized control);
  • Output in 6 different time periods throughout the day: The output power for 6 time periods within 24 hours can be customized (such as full power charging during high daylight hours and low-power maintenance mode at night), adapting to changes in daytime and nighttime lighting and electricity load, and optimizing energy allocation strategies.
  • Multiple security protection design:
  • Built in overcharge, overdischarge, short circuit, reverse connection, and over temperature protection functions, coupled with lightning protection circuit design, ensure stable operation of the system in harsh environments;
  • Support battery reverse connection protection to avoid equipment damage caused by wiring errors and improve installation safety.
