6.2.1 Connecting the AC output

A round plug connector system is used, which allows various cable diameters to be
used in the cable outlet. For this reason, the accessories kit includes a PG13.5 pressure
screw and a PG16 pressure screw. Check which screw fitting is the right one for your
AC cable.
To connect up the AC output, follow these steps:
1.

Check the grid voltage. If this is constantly higher than 253 V, the Sunny Boy SB
1100LV will not be fully operational. In this case, contact the local grid operator
for assistance. The inverter can feed into the grid at an output voltage of 260 V for
brief periods. However, the average output over a 10 minute period may not
exceed 253 V.

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.

Now take the AC connection socket parts from the accessories kit and connect up
the cable, with shielding and insulation stripped, as described on the following
pages:

Warning! Voltage!
Before you connect the mains cable to the AC connection socket, make
sure that no voltage is present in the cable.
