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
4.4 "Viewing and Altering Parameters"
(page 25) and section 10.3 "Adjustable
System Parameters" (page 51)).
TR-TempOV Excessive transformer 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 transformer 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 transformer
temperature has sunk by 5°C.
VAC-High Output voltage too high Check the value of the "22-1
VacNominal" parameter setting (see
section 10.3 "Adjustable System
Parameters" (page 51)).
VAC-Low Output voltage too low Check the value of the "22-1
VacNominal" parameter setting (see
section 10.3 "Adjustable System
Parameters" (page 51)). For an
explanation, refer to point 7 of section
11.2 "Troubleshooting FAQs" (p 58).
Short-circuit in the system Check the system for a possible short-
circuit.
VBatHigh Battery voltage too high: Check the battery connections.
External charger with excessive
charging voltage Check the external charger.
One or more defective batteries with
high internal resistance Check the batteries.
