The buzzer only sounds while the inverter is being supplied with
power from the solar modules.
The relay remains in its switched position, even when the DC supply
is terminated due to the onset of darkness.
A service code can only be acknowledged (and the relay reset) when
the DC supply is available.
The buzzer sounds briefly while the inverter is starting up - this is a
standard part of the initialisation routine and does not indicate a mal-
function.
