4.4 Jumper for System Configuration
By setting the jumper, you configure the Sunny Boy for different grid topologies. This means that
operation in system configurations without neutral conductors, such as 208 V and 240 V Delta, is
possible. The following figure provides an overview of the standard settings, the settings for grids
without neutral conductors, and the settings for the fan test.
* The Sunny Boy 8000-US must not be connected to a 208 V grid.
