6.2. 1 Connecting the AC Output
To connect the AC cable, proceed as follows:
1. Check the grid voltage. The Sunny Boys were prepared for the DIN VDE 0126--
1-1 in two steps. In the first step the inverter disconnects from the grid when the
grid voltage exceeds 253 V.
In the second step the Sunny Boy can feed into the public grid at a maximum out-
put voltage of 260 V for brief periods. However, DIN VDE 0126-1-1 stipulates
that the 10-minute average must not exceed a voltage of 253 V. That means, if
the grid voltage is constantly 254 V (e.g.), the inverter disconnects itself from the
grid. In this case, contact the local grid operator for assistance.
DIN VDE 0126-1-1 only applies in Germany. See section 8.4. 3 "Country-specific
Parameter Settings" (Page 43) for all other preset country values of your inverter.
2. Isolate the grid connection (switch the line circuit
breaker to its "off" position), make sure it cannot
be switched back on, and test to make sure no
voltage is present.
3. Remove the screws that secure the case of the
Sunny Boy and carefully remove the cover. Re-
move the PE connection from the cover.
4. Connect the main cables as shown in the figure.
Use the supplied cable feed-through.
"L" and "N" must not be swapped.
