The battery preservation mode can be quit by manually starting the Sunny Island. If a charging
current is detected within 5 minutes (see above) the Sunny Island remains in operation; otherwise,
it is disconnected again.
12.6 Battery Diagnostics
In the menu "320 Battery Diagnosis", many values are displayed that provide information on the
past operational behavior of the battery. These values are helpful in checking the efficiency of the
set parameters and in viewing the typical operating conditions of the battery
(see section 17.3 "Diagnosis" (Page 178)).
