Fronius Personal Display DL - Display Values for a Total System in the Now Display Mode

66
The insulation resistance is the resistance between the positive or negative pole of the
photovoltaic system and the ground potential. If an insulation resistance > 500 kilohms is
shown, this means that the photovoltaic system is adequately insulated.
An insulation resistance of less than 500 kilohms indicates an error.
When the insulation resistance is less than 10 megaohms, the display differentiates be-
tween:
- negative potential of the ground (polarity sign '-')
- positive potential of the ground (polarity sign '+')
Display values for
a total system in
the 'Now' display
mode
The Fronius Personal Display DL can show the following power data in the 'Now' display
mode for a total system:
Display example of a negative potential
(polarity sign '-')
Short circuit between DC- lead and
ground
Display example of a positive potential
(polarity sign '+')
Short circuit between DC+ lead and
ground
Date
When the date on the inverter or a system
upgrade is changed, this changes the
date on all devices connected via Solar
Net.
Time
When the time on the inverter or a system
upgrade is changed, this changes the time
on all devices connected via Solar Net.
Output power
Power (in Watts) currently being fed into
the grid
Date
When the date on the inverter or a data
communication component is changed,
this changes the date on all devices con-
nected via Solar Net.
