SolarEdge inverter: production issue detected — what to do
This alert means the inverter's voltage is low and it is not producing energy. SolarEdge points to underperforming power optimizers, for example from shade, snow, dirt, or a malfunction. Check for snow or shade from the ground and contact a professional if it does not clear.

What we see across our fleet
- We have seen this fault on 1,125 SolarEdge systems, 12.7% of the 8,871 SolarEdge systems we monitor (last 12 months).
- Once it appears, the system usually clears it in about 28.9 hours (median), and 3.5% clear within 24 hours.
- Replacement cases on record involve these SolarEdge models: U650-1GM4MRMU-A05 (371), USE11400H-USSKBEZ8 (365), SE7600H-USMNUBL75 (118), NX13000T-US00UCYN4 (84), SE10000H-USMNUBL75 (61).

Common causes
- Snow, dirt, or leaves covering panels.
- New shade from trees or buildings.
- Power optimizers underperforming or malfunctioning.
- A DC design or installation problem.
Safe steps to try
- Note the alert Record the time and alert text in the SolarEdge app.
- Look at the panels From the ground, check for snow, debris, or shade. Do not climb on the roof or touch the panels.
- Recheck in full sun Look at production again in clear daylight. Low light alone can look like a production problem.
- Check the breaker and lights Confirm the solar breaker is on and note the inverter status lights.
When to call a professional
Otovo services these systems and can diagnose this fault for you. Call if the alert persists in full sun. A technician can check the optimizers and strings.
Frequently asked questions
- Is this dangerous?
- The alert is about lost production, not safety.
- Can I clean the panels?
- Stay on the ground and do not climb on the roof. Ask a professional about cleaning.
- Will it clear itself?
- If the cause is temporary like snow or shade, it may.
