If the solar panels are covered in snow, is it better to turn off the inverter?

Here are some advices:

Operating Status of the Inverter: If the solar panels are completely covered with snow, the inverter may enter standby mode because there is insufficient sunlight to generate electricity. In this case, the inverter will not consume much power, so manual shutdown is generally unnecessary.

 

Safety Considerations: If you are concerned that snow might damage the system—for example, melted snow could cause moisture to enter the equipment—you can choose to shut down the inverter to ensure safety.

 

Battery Protection: If your system includes battery energy storage and there is no sunlight for an extended period (e.g., more than 72 hours), certain models of inverters (such as the X3G4) may automatically put the battery into sleep mode to protect it. In this case, no manual intervention is required.
