Fronius Sting Input Combiner

When more solar module strings are combined to one solar module string prior to the inverter, the solar module string current may exceed the permissable DC input terminal current rating of 20 A.

In this case the DC cables can be connected to the Fronius IG Plus using a string input combiner as an option.

The following additional components are required for connecting combined solar module strings using a DC string input combiner:
- 2 string input combiners
- cable lugs (select cable lugs that match the available DC cables)
- hexagon screws
- hexagon nuts (matching the cable lugs)

Please note that these are sold in singles.
