3rd step: Connect loads
Notes
Connect loads that must not be deactivated by the solar charge
controller deep discharge protection, e.g. emergency lights or radio
connection, directly to the battery.
Loads with a higher current consumption than the device output
can be directly connected to the battery. However, the solar charge
controller deep discharge protection will no longer intervene. Loads
connected in this manner must also be separately fused.
Label the load connection cables as a plus cable (L+) and a minus cable (L–).
Lay the load connection cables in parallel between the solar charge controller and
the load
First connect the L+ load cable to the correct pole of the right pair of terminals on
the solar charge controller (with the lamp symbol), then connect the L– cable.
Replace the load fuse or switch on the load.
4th step: Final work
Fasten all cables with strain relief in the direct vicinity of the solar charge controller
(clearance of approx. 10 cm).
4.2.3 Grounding
The components in stand-alone systems do not have to be grounded – this is not stand-
ard practice or may be prohibited by national regulations (e.g.: DIN 57100 Part 410:
Prohibition of grounding protective low voltage circuits). Consult the technical manual
for more information.
4.2.4 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.
5. 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.
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 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 overcurrent
Protection from device overtemperature
Protection from overvoltage at the load output
Protection from the wrong connection sequence
