PV-related Events
ID Status Description
message
103 PV current is too Too many PV modules connected in
high/waiting parallel. Should only appear on newly
installed systems.
115, PV ISO too low The resistance between ground and PV
260 is too low for the inverter to start up.
This will force the inverter to make a
new measurement after 10 minutes.
258 PV voltage too DC voltage is too high.
high/waiting
278 DC voltage high warning.

Internal Events
ID Status Description
message
201–208 The internal temperature of the inverter is
too high.
209, 210 Voltage on DC bus is too high.
211 Fan rpm low Fan speed is too low.
213–215 Internal error. Voltage measured before and
after the relay differs too much.
216–218 Current measured on AC side is too high.
219–221 Internal error. Voltage measured before and
after the relay differs too much.
225–240, Failure in memory/EEPROM.
275
241, 242, Internal communication error.
245, 249
248 Internal CPU error.
252–254 Current measured on AC side is too high.
243, 263 Internal error.
279 Temperature sensor error.
280 Self-test 24-hour timeout. Self-test must run
at least once per 24 hours.
281 Too many RCMU events during the past 24
hours.
Only 4 automatic reconnect attempts after
event 34 is allowed during a 24-hour period.
The inverter will automatically try to
reconnect after a certain period.
282 Grid code settings invalid.
283 Gatedrive error.
Action
Check number of strings in parallel and current
ratings. Has the current limit been exceeded?
Reconnect strings in parallel.
Make a visual inspection of all PV cables and
modules for correct installation according to the
installation guide. The event could indicate that
the PE connection is missing.
Check that PV installation and layout correspond
to recommendations in the manuals.
Check that PV installation and layout correspond
to recommendations in the manuals.
Action
Check that the inverter is not covered and
that the ventilation duct is not blocked.
If event persists, reset the inverter by discon-
necting DC and AC, using the switches. If the
event is repeated, check the maximum PV
voltage using the display to see if it is above
the limits.
Check if the inverter fan is blocked.

If the event is repeated, call service.
Restart the inverter. If event persists, call
service.
If the event is repeated, call service.
None.
Wait up to 24 hours. If event 34 also occurs,
follow the action for event 34.
Restart the inverter. If event persists,
reconfigure the grid code settings.
Restart the inverter. If event persists, call
service.
