SolarEdge inverter stopped producing
Your SolarEdge inverter has stopped producing power, with or without an error code. This page covers what the lights and codes mean, what to check first, and the causes behind it.
What the lights mean
| What you see | What it means |
|---|---|
| Solid green and solid blue | Producing normally and connected to monitoring. After a restart it can take up to five minutes to get here. |
| Flashing green and flashing blue | AC is connected but the inverter is not producing, and its link to monitoring comes and goes. Seen after a power surge, an outage or an interrupted firmware update. |
| Solid green, but the app or the home's meter shows no solar | The green light alone does not prove power is reaching the house. Production can stop while the light stays solid green. |
| Green light with no blue light, on models without a screen | The inverter is powered but not connected to SolarEdge's monitoring servers, so check the app before deciding production has stopped. |
| Solid red, with green blinking | The inverter has a fault and is not producing normally. Read the code in SetApp and compare the lights with SolarEdge's LED status reference. |
| No lights at all, and nothing in the app | The inverter is not running, even if a separate battery on the site keeps working. Check closely that the red switch is really on. |
| Blinking green, then solid blue after a full restart, with no production | The blue light shows it is connected to monitoring, but the restart did not bring production back. |
Error codes that go with this problem
| Code | What it means |
|---|---|
| 18X86, Isolation Error, or DC current leakage to ground | The inverter found DC current leaking to ground and blocks production until the leak clears or is fixed. It often shows in wet weather and can clear once things dry. |
| 18x100, 3xBE, or arc fault detected | The inverter detected an arc and locked itself out. It needs a reset on site before it produces again. |
| 18xB5, 18xB7 or another code starting 18xB | SolarEdge's error-code guide lists these as overvoltage inside the inverter or power module voltage imbalance, marked Contact Support, RMA related. Some show as a surge. |
| 137 RCD Test, 18x14, 18xA5, 18xBE or 18xD6 in the error log | Error log entries such as RCD Test, Inv. Power Error, Tz Over current and Swing Rdiff Overheat. SolarEdge's error-code guide does not list these exact codes. |
| 18x7B, 18x1C, or a screen message about voltage | 18x7B was described as grid voltage too high, and SolarEdge's guide lists 18x1C as line voltage low. DC voltage not safe! shows just before the inverter restarts. |
| 8x7B, 8x7C, 8x56 or another code starting 8x | SolarEdge's guide for three phase inverters lists 8x7B and 8x7C as over current and 8x56 as power train error, all Contact Support RMA. 8x1C and 8x38 are grid voltage faults. |
| Night Mode | The inverter is seeing less than six volts DC from the optimizers. In darkness that is normal. |
| App or email alert: not producing energy - low voltage, or production issue detected | Monitoring alerts. The low voltage one may appear only under closed alerts. The status error email says to check the error logs and contact SolarEdge Support if the weather was fine. |
What to check first
- Open the SolarEdge app. A red or yellow inverter icon means the inverter has no internet, which is a different problem from a production stop. Show closed alerts as well, since some alerts only appear there.
- Check that the inverter's red on/off switch is really on, along with the DC disconnect and any other solar disconnect. A switch that looked on in a photo was actually off. Check for snow or shade on the panels.
- Note any code on the inverter screen or in SetApp, and which lights are on and whether they are solid or flashing.
- Restart the inverter: switch its toggle off, then the DC disconnect, then the solar breakers in the main panel. Wait a couple of minutes, then switch them back on in reverse order.
- After the restart, allow up to five minutes. You may hear relays click. Production is back when the lights go solid green and solid blue.
- If the fault returns after the restart, get the inverter online so SolarEdge can check it remotely, or book a site visit. If your installer is gone, SolarEdge has shipped owners replacements directly, but has also refused an owner, who found a new installer.
Safety. SolarEdge says an arc fault that is not fixed is a fire risk. After the inverter is switched off, its DC voltage takes time to bleed down to a safe level.
