The solar charge controller immediately begins operation once the battery
is connected or the external fuse is inserted.
The displays of the solar charge controller show the current operating
mode. User intervention or user settings are not required.
PROTECTION FUNCTIONS
The following integrated protection functions of the solar charge control-
ler ensure that the battery is handled as gently as possible.
The following protection functions are part of the basic function of the
controller:
-
Overcharge protection
-
Deep discharge protection
-
Battery undervoltage protection
-
Solar module reverse current protection
The following installation faults do not damage the controller. After
correcting the fault, the device will continue to operate correctly:
-
Protection from solar module short circuits / incorrect solar
module polarity1)
-
Protection from short circuits at the load output or excessive
load current
-
Protection from battery connection with incorrect polarity
-
Protection from solar module overcurrent
-
Protection from device overtemperature
-
Protection from overvoltage at the load output
-
Protection from the wrong connection sequence
1 The reverse-polarity protection of the solar module in a 24V system is
only provided up to an open-circuit module voltage of 36V.
