Connect the PV string voltage by switching on the DC switch,
referring to section 4.4.2. Figure 4. The inverter starts
automatically when it senses DC voltage greater than 250
VDC. All of the LEDs will shine. The LCD will display
drawing A.

After three seconds the LCD will change from drawing A to
drawings B1 and B2. The green LED will flash to indicate
that the DC input power is less than sleep power. The yellow
LED will shine steadily to indicate the absence of utility
power.
