5. Operation
The solar charge controller immediately begins operation once the battery is
connected or the external fuse is inserted.
The display of the solar charge controller shows the current operating mode.
User intervention or user settings are not required.
Protection functions
The following integrated protection functions of the solar charge controller
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 destroy the controller. After cor-
recting the fault, the device will continue to operate correctly:
• protection from solar module short circuits / incorrect solar module
polarity
• protection from short circuits at the load output or excessive load
current
• protection from solar module overcurrent
• protection from device overtemperature
• protection from overvoltage at the load output
• protection from the wrong connection sequence
6. Maintenance
The solar charge controller is maintenance-free. All components of the PV
system must be checked at least annually, according to the specifications of the
respective manufacturers.
X Ensure adequate ventilation of the cooling element.
X Check the cable strain relief.
X Check that all cable connections are secure.
X Tighten screws if necessary.
X Terminal corrosion
