Firmware V1.1 Now Available for BCDC Alpha

9th December 2025

A new firmware update (V1.1) is now available for the BCDC Alpha and BCDC Alpha R range of chargers.

Applicable part numbers:

  • BCDC12025B
  • BCDC12050B
  • BCDC12050R

Key Improvements:

  • Better Sharing Between Alternator and Solar
    • More efficient charging when using vehicle alternator and solar input at the same time.
  • Stronger Solar Performance at Higher Panel Voltages (up to 48Voc)
    • If you’re running panels in the 32–48Voc range, you should see more consistent and effective solar charging.
  • Improved Solar Charging in Dappled Shade
    • More stable solar performance when light levels are changing, such as driving through trees or built‑up areas.
  • Improved Charging When an Inverter is Running
    • More reliable charging even when an inverter is in use and drawing power from the battery.
  • Clearer “Output Battery Disconnected” Detection
    • Enhanced fault detection to help protect both the charger and your system from unsafe operating conditions.
  • Improved Detection of Poor or Faulty Cabling
    • Better recognition of wiring issues such as high resistance, poor connections, or undersized cables.
  • Added Recovery Time After Chargeback to Vehicle Battery
    • A short pause before resuming normal charging allows the vehicle’s start battery to recover after chargeback.
