How to Fix / Troubleshooting
Fire risk: Excessive heat can lead to insulation failure. Address promptly.
- Step 1 – Reduce current: In the Shell Recharge app, lower the maximum charging current (e.g., from 32 A to 16 A) and observe if temperature improves.
- Step 2 – Improve airflow: Ensure the charger is not covered or enclosed in a tight cabinet. Provide at least the clearance recommended in the manual.
- Step 3 – Check for direct sun: If installed outdoors, consider shading the unit from direct midday sun.
- Step 4 – Electrician check: Have a qualified technician open the unit (with power off) and inspect terminals, contactor, and internal wiring for discoloration or melting. Retighten or replace as needed.
- Step 5 – If overheating persists: Internal components such as the contactor or power supply may be degraded and should be replaced.
