Enphase app shows battery or System Controller not reporting
The Enphase app or Installer Portal shows a battery or the System Controller as not reporting, or shows Grid Mode Unknown. This page covers what the lights and messages mean, what to check first, and the causes behind it.
What the lights mean
| What you see | What it means |
|---|---|
| Battery LED off (IQ Battery 3T and 10T) | The battery is not operating. |
| Battery LED flashing yellow rapidly (IQ Battery 5P) | The battery is starting up and establishing communication. |
| Battery LED flashing red in sequences of two (IQ Battery 3T and 10T) | The battery has an error. |
| Battery LED flashing blue or flashing green on a battery not yet commissioned (IQ Battery 3T and 10T) | The battery is detected on the network but has not been commissioned yet. |
| Battery LED slowly flashing green, slowly flashing blue, or solid green or blue (IQ Battery 3T and 10T) | Slowly flashing green is charging, slowly flashing blue is discharging, and solid is idle. |
| DC disconnect LED flashing red | The battery's DC disconnect switch is disengaged. The battery cannot charge or discharge until it is switched on, when the LED goes solid green. |
| Gateway device communications LED solid red (IQ Gateway) | At least one device is not communicating with the gateway. |
| Gateway network communications LED off or solid red (IQ Gateway) | Off means no network connection. Solid red means a local network connection only, not reaching Enphase. |
Error codes that go with this problem
| Code | What it means |
|---|---|
| Battery Not Reporting | A battery is not reporting to the gateway. |
| Battery Reporting Error, Battery lost the communication with BMU, or IQ Battery/IQ System Controller not communicating | The battery has lost communication with the gateway or the System Controller. |
| System Controller not reporting | The IQ System Controller has stopped reporting to the gateway. After more than 12 hours without it, the system stays grid-tied and the battery stops charging and discharging. |
| Grid Mode Unknown in the operation mode column | The operation mode shown for a System Controller that has stopped reporting. |
| 24-volt control header error at commissioning | An error raised during commissioning about a battery's 24-volt control header. |
| Red in the small window on a battery DC connector | That DC connector is not fully connected. A fully seated connector shows white. |
What to check first
- Look at the battery's LED. Note whether it is on, its colour, and whether it flashes, and compare it with the light table above.
- Look at the battery's DC disconnect LED. If it flashes red, the switch is disengaged and the battery can't charge or discharge. Ask your installer to switch it on.
- Look at the gateway's network LED. If it is off or solid red, the gateway is not reaching Enphase. Once it reconnects it sends the data it stored in the meantime.
- Note when the battery drops off, whether it comes back on its own, and how long it stays away. A dropout at the same time every day is worth telling your installer about.
- If it started right after the gateway was replaced or restarted, tell your installer.
- Call your installer if a battery or the System Controller stays not reporting. After more than 12 hours without the System Controller, the system stays grid-tied and the battery stops charging and discharging.
