With this hookup, the cells are protected with 2 bypass
diodes against the hot spot effect and the additional block-
ing diode protects against reverse current back into the
module. By damage to a module or cable by several mod-
ules in parallel operation, an influence can be prevented
on the other modules with the use of the blocking diode.
Installation Cell-Protector
Applies only to M-Series solar panels with three wire cable!
Attention!
Before using your solar panel, you have to connect the enclosed cell-protector!
■
The cable of with each single M-Series solar panel with
a three wire cable has to be connected to a separate
cell-protector.
Polarities:
red = solar module “+”
blue = solar module “-”
green = middle contact
■
The serial or parallel connection of M-Series solar panels
has to be done after installing the cell-protector(s).
■
The cell-protector has to be mounted and operated in a
dry place, it must not become wet or moist with dew.
Connection of the cell-protector
1.
Screw the 3 wires of the panel cable in the terminal block “Solar”. Please note the colour marking!
Each wire end have to be screwed down in the correct screw terminal.
2.
Use for connection the charge controller a standard 2x1.5mm2 cable at terminal block “Output”.
Two kinds of connection are possible, please see below. Please pay attention to the po/- .
3.
Fix the cable to the base plate of the box by the 2 attached strain relief clamps.
4.
Screw the cap of the box onto the base plate. The connection of the cell-protector is ready.
