Path-Q Solar
How can I distinguish a grid outage from a solar equipment failure?
Answer
Check whether other premises have power, whether the utility reports an outage, and what the inverter displays. During many grid outages, a standard grid-connected solar system will shut down automatically even when sunlight is available; an inverter fault or persistent shutdown after grid power returns points more toward an equipment or communications problem.
Key points
- A whole-property loss of power is consistent with a grid outage but does not rule out a service-panel or system fault.
- Solar production stopping during an outage can be normal and is a safety function.
- Battery-backed systems may behave differently depending on their backup configuration and state of charge.
What it depends on
- Utility power status
- Inverter and battery configuration
- Inverter status messages
- Whether monitoring communications remain available
Risks and trade-offs
- Do not assume solar panels provide power during an outage unless the system is specifically designed and configured for backup operation.
- Do not manipulate disconnects or electrical equipment during an outage unless instructed by qualified personnel.
Information you may need
- Utility outage status
- Inverter and battery status
- Whether power has returned to the property
- System operating and backup documentation
Your next step
What to do next
Check the utility outage channel and inverter status, then contact the installer if the system does not return to normal after grid power is restored.
