NOTE!
When connecting aluminum cables:
▶
▶
NOTE!
Form a min. 4 in. (100 mm) cable loop with all cables.
NOTE!
To ensure that the inverter operates without any problems:

▶
Permitted cables
AC cables with the following design can be connected to the AC terminals of the inverter:
Cu / Al
AC & DC = copper cables (Cu)
The following wire combinations can be used for wiring.
Select a sufficiently large cable cross-section based on the actual device output!

Follow all national and international guidelines regarding the connection of aluminum
cables.
Follow the instructions of the cable manufacturer, especially the note about whether
an annual check to ensure that the cables are firmly attached should be performed.
Make sure that the grid's neutral conductor is grounded. For insulated networks
(without grounding), this is not the case, and operation of the inverter is not possible.
A neutral conductor is required for measurement purposes when operating the
inverter. The neutral conductor must have a current carrying capacity of at least 1 A.
