Possible Causes

Corrupted configuration data in EEPROM/flash, Interrupted firmware update, Failing memory chip on control board, Power surge during write operation

How to Fix / Troubleshooting

Safety first: Most steps are low-voltage and can be done with power ON, but opening the unit requires power OFF.

  • 1. Factory reset: Use the EvoCharge interface (buttons, app, or web) to perform a factory reset to default settings. Reconfigure current limits and network settings afterward.
  • 2. Firmware reflash: If EvoCharge provides firmware files, perform a full firmware reflash, which often rewrites configuration areas.
  • 3. Avoid power interruptions: During any update or reset, ensure the charger remains powered to prevent further corruption.
  • 4. Control board replacement: If E15 returns after reset and reflash, the memory hardware on the control board is likely defective and the board should be replaced.

Document your configuration before resetting so you can restore custom settings afterward.
