100
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 '+')
Options If the DatCom component for the required options is not available, the message "N.A." (not
available) is shown.
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
GFDI status
For grounded solar modules
If there is no ground fault in the system,
"GFDI OK" is displayed
GFDI = Ground Fault Detector Interruptor
Time (datalogger option)
When the time on the inverter or a system
upgrade is changed, this changes the time
on all devices connected via Solar Net.
