The power management function allows you to switch a load on and off based on
the operating condition of the PV system. If the total system power can be sustained
at a level set under “” for a period of time set under “”, the load will
be switched on until the power drops to a level set under “” for the period of
time set under “”. In any case, the load will remain switched on at least
as long as set under “” (this may, for example, correspond to the
duration of a washing machine cycle).
Like a timer, the time management function “” switches the load on at
a time set under “” and off at a time set under “”.
If both the power management and the time management functions are activated,
priority will be given to the power management, and time management will occur
only if the power-managed event never occurred.
