Do not be alarmed if ......

  • In the mornings when your Fronius Inverter is booting up it may display an orange fault light.This is a normal function of the inverter. It should be given a few minutes before it will turn green.
  • Your Fronius Inverter when working at peak performance, sound may increase as it works to produce more wattage.
  • The fault light may also display in the evenings when your inverter is preparing to shutdown. This is again a normal function of the inverter. It is preparing to go to sleep and wake up for another big day just like you. The display screen will go blank.
  • There is no sunlight. Your solar pv system functions only from the performance of the SUN. This means at night time your solar power system will be dormant just as you are until sunrise.
