Solar outages
Your rooftop solar system on the may occasionally be affected by an outage or temporary export limitation. This means your system is temporarily unable to export electricity to the grid, even though it may still be generating power for your home.
How could this affect my solar system?
- Your solar exports to the grid may be temporarily reduced or paused
- Your electricity supply will not be interrupted
- The impact will generally last only a short period of time
- Once the emergency condition has passed, normal operation will resume automatically
What do I need to do?
In most cases, you don’t need to do anything, and your system will return to normal automatically once the event has ended.
You do not need to:
- Reset your inverter
- Contact your solar installer
- Contact Jemena
- Turn your system on or off
Your property will continue to have access to electricity, and you can keep using your power as usual.

Digital system outage
Utility server and/or any other related digital system outages that prevent new and/or replaced inverter commissioning testing as part of the connections process.
| Date of event | Start time * | End time ** |
| 22/12/2025 | 22/12/2025 13:40PM |
23/12/2025 11:30PM |
* Date and time when first system outage event occurred.
** Time that the system was restored or estimated restoration time or estimated time when we provide the next update.
New and/or replaced inverter testing
As part of ongoing commissioning activities, we are conducting daily testing of new solar microgeneration units and replacement of legacy solar microgeneration units to confirm that they are capable of remotely interrupting or curtailing electricity generation.
| Date of event | Start time | End time |
| Ongoing (daily) | Ongoing (daily) | Ongoing (daily) |
Annual testing (sub-network and network-wide)
Sub-network – annual testing of emergency backstop capability of solar systems at sub-network level. Network-wide – annual testing of emergency backstop capability of solar systems at network-wide level.
| Date of event | Start time* | End time** |
| 17/03/2026 | 11:00 AM | 12:30 PM |
* Date and time when first active generation curtailment occured or is planned to occur.
** Time that the last active control for curtailment event was cancelled, completed or planned. Solar PV system maximum export limit reinstated shortly afterwards on this day.
Emergency Minimum System Load (MSL) event
In rare circumstances, your solar system may be temporarily reduced or switched off during a Minimum System Load (MSL) event. This occurs when rooftop solar generation is very high and demand for electricity from the grid is very low, creating conditions that can affect the stability of the electricity system and increase the risk of widespread outages.
To help manage these events, the Victorian Emergency Backstop Mechanism allows electricity distributors to temporarily reduce solar exports when directed by the Australian Energy Market Operator (AEMO).
