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?
— Have the DC input breakers been opened?
— 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?

Contact SolaX Customer Service for further assistance. Please be prepared to
describe details of your system installation and provide model and serial number
of the unit.
