If your charger has no lights and/or is tripping the onsite RCBO, it may indicate a power issue at the installation. In some cases, the RCBO may need to be replaced, which would require an electrician to visit the site.
⚠️ Please note: RCBO replacement is not covered under the charger’s warranty.

1. Check the RCBO switch

• Does the switch stay in place, or does it feel sticky or loose?
• If it won’t stay up, this may indicate a fault with the RCBO itself.

2. Limit the charge rate

• In the Simpson & Partners app, limit the charge rate to 16A and check if the RCBO still trips.
• If it doesn’t trip at a lower rate, this may point to an issue with the power supply or breaker capacity.

3. Check for power output (advanced)

• If you feel comfortable and are competent with electrical work, use a voltmeter to check whether there is power output from the RCBO terminals.
• If there’s no output, the RCBO may be faulty or tripped.

4. Contact an electrician

• If the above steps don’t resolve the issue, contact a qualified electrician to inspect and replace the RCBO if needed.
