Green LED not flashing or no secure power message — PV system output too low

What does Green LED no flash, no secure power message mean?

The PV system's output is too low if the green LED does not flash, and no message that the secure power supply operation mode is enabled appears on the display, or the control lamp of the outlet does not glow. This usually means solar irradiation is insufficient or the connected load requires more power than currently available.

• Low solar irradiation on the PV system.
• Connected load requires more power than currently available.
• Outlet's switch not set to secure power supply operation.
• Switch, outlet, and control light for secure power supply operation are not correctly connected.

Click steps to track your progress.

1. 1

   Ensure that the outlet's switch is set to secure power supply operation.

2. 2

   If irradiation is too low, wait for it to increase (e.g., later in the day or when clouds clear).

3. 3

   Connect a load with lower power consumption to the outlet.

4. 4

   Verify that the switch, outlet, and control light for secure power supply operation are correctly connected.
