HS-TempOV Excessive heatsink temperature:
The Sunny Island 3324/4248 has been
operated under overload conditions for
an extended period of time.
The ambient temperature is very high
while the Sunny Island 3324/4248 is
being operated with a heavy load. The Sunny Island 3324/4248 can only
restart when the heatsink has cooled by a
minimum of 5°C.
Place the Sunny Island 3324/4248 in
standby mode for a few minutes to allow
the fans to cool the inverter.
Switch off some of the connected loads in
the stand-alone grid to avoid immediately
overloading the Sunny Island 3324/4248
after a restart.
If the "40-2 Autostart" parameter is set to
"On", the Sunny Island 3324/4248
automatically starts once the heatsink
temperature has sunk by 5°C.

Restart If this fault frequently occurs please
contact the SMA hotline (see section 20
"Contact" (Page 151)).

PRevOver Generator or grid reverse power has
exceeded the defined limits ("24-11
PGenRevers" parameter). A "!" appears
in the display under 'Generator Run'. Remove the 20 minute generator/grid
lockout by setting the "24-3
GenOperation" parameter to "Release“
or wait 20 minutes for the lockout to be
automatically released (see also Page 79
under 5. "Release" Setting).
RelayFail Device fault If this fault frequently occurs please
contact the SMA hotline (see section 20
"Contact" (Page 151)).
TBatHigh The battery temperature is too high.
Cause: The Sunny Island 3324/4248 can only
restart when the batteries have cooled by
a minimum of 2°C.
If the "40-2 Autostart" parameter is set to
"On", the Sunny Island 3324/4248
automatically starts once the temperature
has sunk sufficiently.
poor battery ventilation Check the room fan for correct operation.
high ambient temperatures Avoid high ambient temperatures in the
battery environment. Provide adequate
ventilation.
excessive battery charging current Reduce the value of the "23-4
AmpdcBatMax" parameter (see section
8.1 "Preparation" (Page 63) and section
17.2.2 "Adjustable System Parameters"
(Page 134)).
