 Split phase TN and TT type grids
The following diagrams show three PVS300 solar inverters connected to split phase
TN and TT grids. In a split phase TN or TT type grid, the voltage seen by each
PVS300 inverter is the line-to-line voltage. The allowed line-to-line RMS voltages are
208, 220, 230 and 240 V. The following table shows the different line-to-earth
voltages for split phase TN or TT type grids.
