and carries out load-free disconnection of the
generator from the stand-alone grid.
The generator management signals to GenMan
that the generator is no longer requested.
‒
During the shut-off delay time, the generator
management cannot request the generator
again and the off-grid inverter cannot connect
the stand-alone grid to the generator again.
GenMan stops the generator.
GenMan signals to the off-grid inverter that the
shut-off delay time has ended.
