The buffer memory can store a maximum of six logging points. Data is only logged while
the inverter is running (output greater than 0 W). The logging interval is permanently set at
30 minutes. Data can be recorded on the buffer memory for a three-hour time period as a
result.
When the buffer memory is full, the oldest data in the memory will be overwritten by the
next batch of data.
IMPORTANT! The buffer memory requires a permanent power supply.
If there is a power failure while the inverter is in operation, all the data in the buffer memory
will be lost. To avoid losing data during the night, the automatic night switch-off facility must
be deactivated (switch the "Night Mode" setup parameter to ON - see the Datamanager
2.0 Operating Instructions, section "Setting and displaying the menu items", "Viewing and
adjusting parameters in the DATCOM menu item").
On the Fronius Eco or Fronius Symo 15.0-3 208, the buffer memory also functions with just
a DC supply.
