7. Grounding
The components in stand-alone systems do not have to be grounded - this is not
standard practice or may be prohibited by national regulations.
Consult the technical manual for more information.
8. Lightning protection
In systems subjected to an increased risk of overvoltage damage, we
recommend installing additional lightning protection / overvoltage protection to
reduce dropouts.
Consult the technical manual for more detailed information.
9. Operation
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.
10. 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 low voltage protection.
● Solar module polarity reverse protection
The following installation faults do not destroy the controller. After correcting 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 battery connection with incorrect polarity.
● Protection from solar module over current.
● Protection from device over temperature.
● Protection from overvoltage at the load output.
● Protection from the wrong connection sequence.
