533_Stdby t beg
0 ... 23 h:
Beginning of period when low-strain operation of battery is
permissible (see “535_Stat StopT”)
534_Stdby t end
0 ... 23 h:
End of period when low-strain operation of battery is permis-
sible (see “535_Stat StopT”)
535_State StopT
L4 ... O3:
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
every four hours.
536_Fan on del
0 ... 1440 min:
ON delay for battery room fan
In order to use this setting, “511_Bat Fan” must be set to “Installed“
537_Fan off del
0 ... 360 min:
OFF delay for battery room fan
In order to use this setting, “511_Bat Fan” must be set to “Installed“
538_Iloss nom
Specific leakage current of battery during float charge at 20 °C
100 ... 0 mA per 100 Ah
Approximate values:
30 mA/100 Ah
for new batteries
80 mA/100 Ah
for batteries strongly aged
This value is NOT automatically determined by the Sunny Island. Battery man-
agement can therefore be optimized by manually adjusting the value from time
to time.
