9.5 Restarting the Automatic Shutdown
To restart the Sunny Island 3324/4248 after it has switched off due to batteries that
are too deeply discharged, proceed as follows:
• Switch off the DC circuit breaker.
• After waiting 5 minutes switch the DC circuit breaker on again. The Sunny Island
3324/4248 runs through the INIT phase.
• Once the INIT phase is finished, the message "To start press ENTER" is displayed.
Press the "ENTER" key.
• Monitor the generator start and check that the Sunny Island 3324/4248 switches
to "CHARGE" operating mode (battery charging mode).
• Check that all other energy generators in your system are also working correctly.
A complete shutdown indicates that one or more of the system
components have failed or are not working properly. Check the
components of the system for possible faults or incorrect
parameter settings before attemping to restart the system.
You must wait at least five minutes to allow the capacitors to
completely discharge before switching the DC circuit breaker on
again.
Once the inverter is switched on again, it is important that the batteries are
charged. If an autostart generator exists in the system, the Sunny Island 3324/
4248 will start the generator after a few minutes.
If the Sunny Island 3324/4248 immediately switches off with the fault
"VBatLow" (low battery voltage) after restarting, switch off all loads connected
to the AC output. The loads can be reconnected once the Sunny Island 3324/
4248 enters the "CHARGE" operating mode. (Provided that a generator
capable of providing the required power is connected to the system.)
