In case of deep-cycle discharge the device will switch off to
reduce strain on the battery, if no charging current of a
minimum of 1 A flows into the battery for more than 5 min-
utes within the defined time period (see also “533_Stdby t
beg”, „534_Stdby t end“).
The low battery load mode is always activated, when one battery state lower is
reached. However, from 6 am to 6 pm the Sunny Island attempts to switch on
