Behaviour
The inverter will automatically
attempt to connect again and,
if possible, will resume feeding
energy into the grid
-
The inverter is not feeding any
energy into the grid.
The inverter will automatically
attempt to connect again and,
if possible, will resume feeding
energy into the grid
Short-term interruption while
feeding energy into the grid
The inverter resumes with its
startup routine.
The inverter is in bootloading
mode and is not feeding any
energy into the grid
Short-term interruption while
feeding energy into the grid
The inverter resumes with its
startup routine.
The inverter is not feeding any
energy into the grid for safety
reasons.
The inverter is not feeding any
energy into the grid.
