In grid-connected systems, we recommend the use of one of the electronic protection
mechanisms described here. Please note that overvoltage on the Windy Boy can lead
to destruction of the device. In addition to this, you lose the right to all warranty
claims - even if the maximum input voltage of the Windy Boy is only exceeded for a
short time.
The electronic protection systems described here are preferable to mechanical
solutions (pitch control, "turning out of the wind") in every case.
Any other use of the Windy Boy 5000 / 6000 leads to loss of the right to all warranty
claims.
In case of overvoltage, immediately disconnect the DC input of the
Windy Boy 5000 / 6000! The presence of excessive input voltage
can lead to irreparable damage!
When the Windy Boy 5000 / 6000 receives an excessive DC input voltage, it
automatically disconnects from the mains supply and no longer feeds power
into the grid. When the Windy Boy 5000 / 6000 is in operation, you must
always first disconnect the AC voltage (mains supply) and only then should you
disconnect the DC voltage from the Windy Boy 5000 / 6000!
