Fronius Energy Package - Manual (Page 112)

The inverter disconnects automatically from the grid, the grid is then monitored as specified
and the inverter attempts to resume feeding energy into the grid.
*) If the status code is displayed all the time: Notify a Fronius-trained service engineer.
**) Fault is rectified automatically. If this status code keeps recurring, contact your system
engineer.
Status codes –
Class 4 Some of the class 4 status codes necessitate intervention by a Fronius-trained service en-
gineer.
Code Description Behaviour Remedy
301 Overcurrent (AC) Short-term interruption while
feeding energy into the grid.
The inverter repeats its start-
up routine.
*)
302 Overcurrent (DC)
303 DC module overtemperature (PV) Short-term interruption while
feeding energy into the grid.
The inverter repeats its startup
routine.
Purge cooling air open-
ings and heat sink; **)
304 AC module overtemperature
305 No power being fed in, despite closed
relays Short-term interruption while
feeding energy into the grid.
The inverter repeats its startup
routine.
**)
306
There is not enough PV power avail-
able for feeding energy into the grid
and no power has been requested
from the battery. Short-term interruption while
feeding energy into the grid.
The inverter repeats its startup
routine. Wait for sufficient insola-
tion; wait for an energy
management command;
**)
307
DC low
DC input voltage too low for feeding
energy into the grid Short-term interruption while
feeding energy into the grid.
The inverter repeats its startup
routine. Wait for sufficient insola-
tion;
**)
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 indicate
any kind of fault.
308
Intermediate circuit voltage too high Short-term interruption while
feeding energy into the grid.
The inverter repeats its startup
routine.
**)
309 PV input voltage too high
313 Battery input voltage too high. Short-term interruption while
feeding energy into the grid.
The inverter repeats its startup
routine. This service code may
occur sporadically even though
there is no actual fault. Switch on, connect or
check battery;
*)
314,
315 Internal system error Short-term interruption while
feeding energy into the grid.
The inverter repeats its startup
routine. *)
324 DC module overtemperature (battery) Short-term interruption while
feeding energy into the grid.
The inverter repeats its startup
routine.
Purge cooling air open-
ings and heat sink; **)
