Sigenergy: System Not Producing Power or Showing a Fault

If your Sigenergy system has stopped producing power, is generating less than usual, or is showing a warning, the steps below will help you check the most common causes before contacting our team.

Please don't attempt any repairs inside the inverter, battery, or switchboard — solar equipment carries dangerous voltages.

Step 1 — Check for a recent power outage or grid issue

Solar inverters automatically shut down during a grid outage for safety and restart on their own once power is restored. If your area has had an outage or a storm, allow 10–20 minutes for the system to restart before investigating further.

Step 2 — Check the LED indicator lights on your inverter

Your inverter has four indicator lights on the front panel. In normal operation, the DC and AC indicators should both be solid green, and the signal indicator should also be solid green.

A fault is indicated by any light flashing red or showing solid red. Note down exactly which indicator is affected and what colour or pattern you're seeing — this helps us diagnose the issue quickly.

Not sure what the lights mean? See our guide: Understanding your Sigenergy LED indicator lights.

Step 3 — Check the mySigen app

Open the mySigen app and check your system status. Look at the solar production figure — if it's showing 0 kW during daylight hours, or significantly lower than a typical day, that confirms the system isn't producing as expected.

If the app shows an error message or alert, take a screenshot or write down the exact wording before contacting us.

If the app shows the system as offline, try our WiFi reconnect guide first, then recheck production.

Step 4 — Check your switchboard

Check whether any solar or battery circuit breakers or isolators have tripped to the off position. If a breaker has tripped, do not keep switching it back on repeatedly — if it trips again, that indicates a fault that needs a technician.

Step 5 — Restart the system (only if safe and you're comfortable)

If no breakers have tripped and the app or LED lights suggest the system has simply stopped responding, a restart may resolve it.

Turn off the AC switch (labelled "Inverter Supply") inside the Sigenergy Gateway. Then open the left-side cover on the inverter and turn the DC switch to OFF. Wait 3–5 minutes to allow the system to fully power down, then restart by turning the DC switch back ON first, followed by the AC/Inverter Supply switch. Allow a few minutes for the inverter to come back online fully.

If the system restarts and production resumes, monitor it over the next day to confirm it's performing normally.

When to contact us

Please get in touch with our team if:

  • The system stays off after a restart
  • You see a red fault light or app error that doesn't clear
  • Your production is consistently lower than expected
  • A breaker keeps tripping

Contact us immediately and treat it as urgent if you notice any smoke, sparks, a burning smell, or signs of overheating near the inverter or battery. Do not attempt to restart the system in this case.

Email service@brightearthsolar.com.au with your name, address, system model, and the error or light details from above, and our team will help you get it resolved.
