If your inverter's information panel is not displaying a Fault light, check the
following list to make sure that the present state of the installation allows
proper operation of the unit.
— Is the inverter located in a clean, dry, adequately ventilated place?
— Are the cables adequately sized and short enough?
— Are the input and output connections and wiring in good condition?
— Are the configurations settings correct for your particular installation?
— Are the display panel and the communications cable properly
connected and undamaged?
