11.Charge controller schematic diagram
The following sections only
describe the technical grounding
options. The goal is to maintain
the controller functions. The installing engineer must note and
observe the national regulations
in the region of use. The loss of
the protective low voltage status
caused by grounding must be
compensated by corresponding isolation measures for
live parts (protection against
direct contact). If the plus side
is selected for grounding, it
can also be used as an earth
for all system components. All
plus conductors are internally
interconnected in any case.
Only one connection can be
grounded from the minus
connections of the module,
battery and load components.
If your solar system already
provides a minus-side earth,
only one component (in this
example, battery-minus) may be
connected to this earth. Connecting to other minus connections (module or load) bridges
control elements and the fuse.
This causes malfunctions or
even irreparable damage to
the controller. In systems with
preset load–minus–earth (e.g.
grounding antennas) all other
components must be floating.
