Possible Causes
Failed onboard energy metering IC, Loose connections to internal CTs or shunts, Firmware error in metering subsystem, Damaged metering daughter board (if fitted)
How to Fix / Troubleshooting
Safety first: Isolate power before accessing internal metering components.
- Check metering connections: Inspect the wiring from the internal CTs or shunt resistors to the metering IC or daughter board. Tighten any loose terminals.
- Look for damage: Examine the metering area of the PCB for burn marks or cracked components.
- Firmware reset/update: Perform a soft reset via the EO app and check for firmware updates that may address metering bugs.
- Functionality vs. billing: If the charger still operates but E19 affects only reporting accuracy, you may continue limited use while arranging repair, depending on local regulations and your billing needs.
- Replace metering board/PCB: If E19 persists, replace the metering daughter board or the entire main PCB as per EO service documentation.
