11.5 Reactivating the Device Following Automatic Shutdown
If the Sunny Backup 2200 shut down due to critically low battery power, reactivate it as follows:
1. Push the DC stop button on the Sunny Backup 2200.
2. Switch on the Sunny Backup 2200 after waiting one minute.
Push the DC start button on the Sunny Backup 2200.
3. Start up the Sunny Backup 2200 (see section 11.1 „Activation / Startup“ (91)).
4. Use the Sunny Remote Control to monitor the process in which the Sunny Backup 2200 switches
to charge mode.
5. Make sure all other energy generators in the backup system are functioning properly.
NOTICE!
System will shut down if device settings are incorrect.
• Check the entire backup system for errors before and after you reactivate the device.
– Incorrect wiring?
– Component failure?
– Incorrect parameter settings for the Sunny Backup 2200?
• Correct any errors found.
Wait
Wait about a minute before switching the Sunny Backup 2200 on again with the DC start
button. The capacitors need to discharge first.
Information
If, in rare cases, you are unable to restart the device after a minute, wait a little longer and
try it again. This may result due to component tolerances.
Charge the battery
After reactivation, it is important that the batteries are charged. If the grid is available
again, the grid will recharge the batteries after a few minutes.
Disconnect the loads if the Sunny Backup 2200 starts the battery preservation
mode after being restarted
• Check the availability of grid power.
• Check the Automatic Switch Box S for proper functioning.
• Only reconnect loads when the Sunny Backup 2200 is in charge mode.
