7 Configuration
7.1 Automatic Line Voltage Detection
The inverter automatically detects the line voltage that it must feed in. Depending on the voltage and
the phase angle between L1-N and L2-N, the inverter determines whether it is connected to a
208 V or 240 V power distribution grid. If the inverter is configured for the wrong grounding system,
the inverter displays an error message.
