Should the display remain dark for a longer period of time after sunrise
you must check the no-load voltage of the solar modules.
Should the no-load voltage of the modules (at the connecting points of the
FRONIUS IG UNIT) not reach 160 V, it is possibly the case of a defect in
the remaining part of the photovoltaic system.
If the no-load voltage of the solar modules (at the connection points of the
FRONIUS IG unit) amounts to more than 160 V, there may be a basic
defect in the FRONIUS IG unit. In this case you must consult a Fronius
trained service technician.
