Dear Valued Customers,
With Tropical Cyclone Alfred approaching, we urge all customers to take immediate precautions to ensure the safety of your solar and battery storage systems.
General Rule: Safety First!
- If authorities recommend evacuation, shut down your system before leaving.
- If there is a risk of flooding, turn your battery system OFF to prevent short circuits, electrical fires, or permanent damage.
- Never attempt to remove or disconnect battery cables yourself—this must be done by a licensed electrician to prevent electric shock or fire hazards.
- Follow official guidance from Energex, emergency services, and government authorities for storm safety. (Energex Official Advisory)
Shutdown Recommendations by System Type
1. Grid-Tied Solar Systems (Without Batteries)
- Your system will automatically shut down if the grid power goes out.
- However, it is recommended to manually turn off the inverter using the shutdown procedure provided by your installer.
- If you expect strong winds or structural damage, shutting down your system can prevent electrical hazards.
2. Grid-Tied Solar Systems (With Batteries)
- Short Circuit & Fire Risk: If flooding is possible, battery systems must be turned off to prevent electrical short circuits, fires, or explosions.
- How to Shut Down the System Safely:
- Turn off the inverter AC mains isolator.
- Turn off the battery disconnect switch.
- Shut down the PV array via the DC isolator.
- Do not attempt to disconnect or remove any battery cables yourself—this must be done by a licensed electrician.
- If You Are Not in a Flood Zone: The system may remain on for emergency backup power, but if extreme weather is expected, turning it off is the safest option.
3. Off-Grid Solar and Battery Systems
- If staying home: The system can remain on, but ensure batteries and inverters are protected from flooding or debris.
- If flooding is expected: Shut down the system and have a licensed electrician safely disconnect and isolate the battery system.
Battery System Risks & Precautions
- Short Circuits & Electrical Hazards: Water exposure can cause short circuits, leading to fire, electrocution, or irreversible battery damage.
- Lithium-Ion Battery Risks: Water ingress in lithium-ion batteries can result in thermal runaway, overheating, and potential explosions.
- Never Remove Battery Cables Yourself: Disconnecting a battery incorrectly can cause electric shock or system damage—this must always be done by a licensed electrician.
Post-Cyclone Safety – DO NOT Reconnect Yourself!
- Assume the System is Live: Even if the system appears off, treat all components as if they are still electrified.
- Professional Inspection Required: DO NOT attempt to turn the system back on until a licensed electrician or system installer has inspected it.
- Check for Water Damage: If any part of your system was submerged, it may need to be replaced.
