The INFO menu item

Measured values

PV Iso.
Insulation resistance of the photovoltaic system
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 terminals, even if no energy is being fed in by the inverter (from
first or second MPP Tracker)
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! Status codes 306 (Power low) and 307 (DC low) appear naturally every
morning and evening due to low solar irradiance. These status codes are not the result of
a fault.

RCMU

RCMU = Residual Current Monitoring Unit
The inverter is equipped with an RCMU according to Austrian standard ÖVE/ÖNORM E
8001-4-712.
It monitors residual currents from the solar module to the inverter grid connection and dis-
connects the inverter from the grid when an improper residual current is detected.
Additional residual current protection may be needed depending on the installation's pro-
tection system or the requirements of the utility company. In this case, use a type B residual
current circuit breaker with a release current of at least 100 mA.
Device Informa- The device is used to display settings relevant to a power supply company. The displayed
tion values depend on the respective country setup or device-specific inverter settings.
