When a bus over/undervoltage, overcurrent or minimum input voltage appears, the closed
loop control stops the MPPT function and it moves to the next state machine
(STOP_WITH_DELAY). At this point, the power board is waiting for a physical opening of
the relay. During the fixed time (10 msec) the PWM continues to modulate at the DC-DC
stage and the DC-AC stage. At the end of this period, they all switch off. This time is in
accordance with the relay specifications.
