Operating the Sunny Island

10.1.5 Restarting the System after Automatic Shutdown

NOTICE!
System shutdown due to, for example, wrong device settings
• Before and after recommissioning, inspect the whole island grid system for errors
- Wrong wiring?
- Have any components failed?
- Are there any wrong parameter settings on the Sunny Island?
• If applicable, clear the errors.
If the Sunny Island has swiched itself off due to batteries which are too deeply discharged, proceed
as follows to restart:
1. Press the DC stop key on the Sunny Island
Wait!
Wait a minute before you restart the Sunny Island with the DC start key. The capacitors
must discharge first.
2. After waiting for a minute, switch on the Sunny Island.
Press the DC start key on the Sunny Island
Information
If, as in rare cases, it is not possible to restart after one minute, wait a little longer. Try
again. A possible cause can be component tolerances.
3. Start the Sunny Island (see chapter 10.1.1 "Switching On/Starting" (Page 83)).
Charging the battery
Once the system is switched on again, it is important that the batteries are charged. If the
grid is available again, and/or the generator starts, the grid/generator will recharge the
batteries after a few minutes.
4. Monitor the Sunny Island connection in the charging process with the
Sunny Remote Control 1.
5. Check that all other energy generators in the island grid system are working correctly.
