Causes
The battery is empty.
The display contrast is poor
on account of high tempe-
rature.
The display board is not
receiving any voltage
supply.
The PV generator is
(partially) covered with
snow.
Remedies
Have the battery (button cell) replaced
by an expert. The battery is located on
the LCD display board.
This can occur with high ambient tempe-
ratures. The display will operate normally
again when the temperature decreases.
The current feed is not affected by this.
Check that the flat cable between display
and control board is firmly located.
To do this, switch off the solar inverter
and isolate on the DC and AC sides.
Clear the snow from the PV generator
or wait until the snow has thawed.
