USER MANUAL of HPC-250HT
4.2.17
Setting 1 (Detailed Description)
For changing system time and date besides modifying power feeding start and stop
conditions of the HPC-250HT, the Settings tab in the user interface has to be selected.
In the basic state the actually set system time and date are displayed in the corresponding
"Year", "Month", "Day", "Hour" and "Minute" textboxes. Their value can be changed
independently by tapping the "Change" button next to the text box whose content is meant to
be changed. To evaluate the new time or date settings one has to tap the "Set Time" or "Set
Date" buttons, respectively.
To assure system power yield at best possible rate, the power feeding start and stop
conditions can be set individually for each HPC-250HT on the "Settings" tab page.
Before grid connection, the HPC-250HT is continuously monitoring the input voltage
determined by the connected network of solar arrays. The user can define the level of
measured input voltage at which a system startup is initiated by setting a value between 450
and 600 in the "Start Voltage" [V] textbox.
To guarantee the stability of the measured voltage at the input of the HPC-250HT, the
voltage set in the "Start Voltage" textbox has to be stable for a certain time interval. This
user-defined time interval can be set in the "Start Time" [s] textbox to a value between 30
and 600 (equivalent to 0.5 and 10 minutes).
