- The stand-alone grid load current ("11-2 AmpacInverter" parameter) is
greater than the maximum generator current ("24-2 AmpacGenMax"
parameter). Reduce the stand-alone grid load until the stand-alone grid load
current is smaller than the maximum generator current. The Sunny Island
3324/4248 can now switch to the generator.
- The reverse power that can be fed back into the generator for up to five
seconds has been exceeded. A "!" is shown in the display. The generator
cannot be connected for a period of 20 minutes. Set the "24-3 GenOperation"
parameter to "Release" (see Page 79).
2. The Sunny Island 3324/4248 does not switch to the running generator, the
generator control relay (Gen_Request) is open .
- The generator was manually started, even though the "24-1 GenControl"
parameter is set to "Direct" (see Page 76) or "GenMan" (see Page 76).
-
Set the "24-3 GenOperation" parameter to "Run1h" (see Page 78). The
Sunny Island 3324/4248 switches to the generator for a period of one
hour. After one hour, the generator is automatically switched off by the
Sunny Island 3324/4248 and the "24-3 GenOperation" parameter is set
to the previous state.
- You can also set the "24-3 GenOperation" parameter to "Start" (see
Page 77). The Sunny Island 3324/4248 will immediately switch to the
generator. You must note that the Sunny Island 3324/4248 will no longer
switch off the generator. Only when you manually reset the "24-3
GenOperation" parameter back to "Auto" can the Sunny Island 3324/
4248 again assume control of the generator.
- The generator reverse power has been exceeded. A "!" is shown in the
display. Set the "24-3 GenOperation" parameter to "Release" (see Page 79),
the Sunny Island 3324/4248 will switch to the generator.
3. The DC circuit breaker on the Sunny Island 3324/4248 is set to "On" but the
display remains dark.
- The inverter has switched off to protect the batteries from deep discharge (see
also section 11.3 "Deep Discharge Protection/Battery State" (Page 105)). To
restart the Sunny Island 3324/4248, see section 9.5 "Restarting the
Automatic Shutdown" (Page 86).
4. A parameter cannot be changed, even though the installer password has been
entered (see section 8.3 "Password Entry" (Page 69)).
- You are in the "10-Meters" (Measuring data) menu or the "30-Diagnose"
(Diagnosis) menu. You can only read the data values shown here.
- Some parameters can only be changed in standby mode (see e.g. the "23-2
BatType" parameter in section 17.2.2 "Adjustable System Parameters"
(Page 134)). Stop the Sunny Island 3324/4248 as described in section 9.3
