If this is not done and the batteries are still further discharged then the battery state
reaches the last level Critical.
If no charging current flows into the batteries within five minutes of entering this state,
then the Sunny Island 3324/4248 automatically switches to standby mode to avoid
any further deep discharge.
If the battery voltage does not recover within 30 minutes, then the Sunny Island
3324/4248 switches completely off. A complete switch-off can be recognized by the
fact that the DC circuit breaker is switched on but the display remains dark and no
voltage is present at the AC output terminals.
Once fully switched off, the Sunny Island 3324/4248 can only be manually restarted
(see section 4.2.4 "Restarting the Automatic Shutdown" (page 22)).
