Status Codes - Class - Fronius Symo Hybrid 3.0-3-S Operating Instructions Manual

Code Description
143 Emergency power overload
144 Emergency power short-cir-
cuit
145 Status code 143 or 144 has
occurred more than three
times
Status codes – Class 3 includes status codes that may occur while feeding energy into the grid, but gen-
Class 3 erally do not cause the process to be interrupted for any length of time.
The inverter disconnects automatically from the grid, the grid is then monitored as spe-
cified and the inverter attempts to resume feeding energy into the grid.
Code Description
301 Overcurrent (AC)
Overcurrent (DC) or battery not
302
detected
303 DC module overtemperature (PV)
304 AC module overtemperature
305 No power being fed in, despite
closed relays
There is not enough PV power
available for feeding energy into the
306 grid and no power has been
requested from the battery.
DC low
DC input voltage too low for feeding
307
energy into the grid
IMPORTANT! Due to the low level of insolation early in the morning and in the evening, the status codes 306
(Power low) and 307 (DC low) are displayed routinely at these times of day. These status codes do not indic-
ate any kind of fault.
308 Intermediate circuit voltage too high
309 PV input voltage too high
313 Battery input voltage too high.
122
Behaviour
Emergency power mode is
interrupted. The inverter
attempts to start emergency
power mode three times; if
this is unsuccessful status
code 145 is displayed
Behaviour
Short-term interruption while
feeding energy into the grid.
The inverter repeats its start-
up routine.
Short-term interruption while
feeding energy into the grid.
The inverter repeats its star-
tup routine.
Short-term interruption while
feeding energy into the grid.
The inverter repeats its star-
tup routine.
Short-term interruption while
feeding energy into the grid.
The inverter repeats its star-
tup routine.
Short-term interruption while
feeding energy into the grid.
The inverter repeats its star-
tup routine.
Short-term interruption while
feeding energy into the grid.
The inverter repeats its star-
tup routine.
Short-term interruption while
feeding energy into the grid.
The inverter repeats its star-
tup routine. This service code
may occur sporadically even
though there is no actual
fault.
Remedy
Check emergency power cir-
cuit; if this status code keeps
recurring, contact your sys-
tem fitter
