Class 5 status Class 5 status codes do not generally prevent the feeding of energy into the grid, but can
codes restrict it. These status code are displayed until they are acknowledged by pressing a key
(the inverter, however, continues to operate normally in the background).
Behaviour
-
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
The inverter is not feeding any
energy into the grid for safety
reasons.
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 is not feeding any
energy into the grid.
The inverter is not feeding any
energy into the grid.
The inverter is not feeding any
energy into the grid.
