How to Fix / Troubleshooting

Safety: If the housing is too hot to touch comfortably, stop charging and investigate.

Check cable sizing: Confirm that the supply cable cross-section is appropriate for the configured current and run length. Upgrade cable if undersized.
Tighten terminals: With power off, open the charger and re-torque all high-current connections (L, N, PE) and internal busbars.
Improve installation conditions: Provide shade, ventilation, or relocate the charger away from direct sun and heat sources.
Reduce current: Temporarily lower the maximum current in the app and observe whether temperature remains within acceptable limits.
Replace power board if damage is visible: If you see burnt marks or melted plastic near power components, replace the power board.

Charger housing becomes very hot to the touch during normal charging, even at moderate current.
