  Christopher RiveraAug 22, 2025
  If the Fronius Inverter display is completely blank, there might be an issue with the photovoltaic system if the open circuit voltage is less than 350 V. If the open circuit voltage is greater than 350 V, this may indicate a basic fault in the inverter, so notify a Fronius-trained service technician. Also, ensure the AC voltage at the inverter's connections is 230 V (+ 10 % / - 15 %).
