In case of an error, the current injection
is immediately stopped, and the grid relay
is triggered which disconnects the Solar
Inverter from the grid.
In addition, there are the following pro-
tection devices on the grid side and on
the PV generator side:
· Varistors on the grid side
They protect the power semiconductors
in case of high-power, temporary voltage
peaks in the grid, and they discharge the
throttle in case of disconnection from
the grid.
· Varistors on the PV generator side
Varistors offer protection from atmos-
pheric overvoltage (e. g. caused by
remote lightning strikes).
