2.
Before the inverter connects to the grid (it usually takes at least 30 seconds), check on the display of RA.Store-
K-F that:
the power placed under the icon of the pylon of the GRID must be negative and equal as absolute value to
the power place under the icon of the HOUSE (but with positive sign +)
as shown in the example below
(Picture 38, Check n.1).
If the check is not possible because the inverter is linked up to the grid and the screen has changed as the
following in Picture 39 (battery power < 0 W), lower (OFF) the magneto-thermal breaker QG1 (GRID LINE);
wait a minute and raise it, then check the condition described in the previous point
"2”.
If the power shown under the icons
ELECTRICITY PYLON and HOUSE is “0 W”, check that the CT sensor is
correctly installed and there are no interruptions on the cable or any wrong connections
(check eventual
junctions or the connection of the CT connector on the terminal box of the RA-K-F).
