Zappi shows very slow charging rate compared to expected power, without any error code

Safety first: Slow charging is usually not a safety issue but may indicate configuration problems.

• 1. Check Zappi settings: Verify Max Current and mode (FAST vs ECO/ECO+) in the menu. Set to the appropriate value for your circuit.
• 2. Inspect cable rating: Ensure the Type 2 cable is rated for the desired current (e.g. 32 A). Lower-rated cables will cause the system to derate.
• 3. Vehicle status: Check the vehicle’s display/app for any messages about limited charging due to battery temperature or state of charge.
• 4. CT/export limits: If using CTs and export limiting, review those settings to ensure they are not capping current unnecessarily.
• 5. Test with another EV/cable: Compare performance with a different vehicle or cable to isolate the cause.
