The INFO menu item

Measured values

PV Iso.
Insulation resistance of the photovoltaic system
Ext. lim.
External limitation
U PV 1 / U PV 2* (U PV 2 is not available for Fronius Symo 15.0-3 208)
Real-time DC voltage at the DC input terminals, even if no energy is being fed in by the
inverter (from first or second MPP Tracker)
* MPP Tracker 2 must be activated - ON - via the Basic menu
GVDPR
Grid voltage-dependent power reduction
Fan #1
Percentage value of fan target power

LT Status

The status display of the last error that occurred in the inverter can be shown.
IMPORTANT! STATE 306 (Power low) and STATE 307 (DC low) state codes naturally ap-
pear every morning and evening due to low solar radiation. These state codes at this time
are not the result of a fault.
