5.8 Fuse
The fuse should be connected to each
non-grounded pole of the array (in other
words, if system is not grounded, the fuse
should be connected to both positive and
negative terminals).
b) The fuse rating also corresponds
to the maximum reverse current that the
module could withstand (when an array is
shading, the array is loaded into another
parallel module array to generate power),
thus the number of parallel connected
arrays is affected.
c) It is forbidden to connect two or
more strings in parallel and then share
the fuses.
a) The maximum rating of the fuse
connected in series is 30A, and the module

5.7 Wiring
In order to ensure PV system could
operation smoothly, when connecting modules
or connecting loads (such as inverters batteries,
etc.), ensure that the polarity of the cables is
properly connected (Figure 1 and Figure 2).
If modules are not connected properly, the
bypass diode may be damaged. Modules
could be connected in series to increase
voltage. Connecting modules in series by
inserting the positive terminal of one module
into the negative terminal of the next module.
Figure 1 shows the serial connection of
modules. Modules could be connected in
parallel to increase current (shown in Figure 2).
Connecting modules in series in Parallel by
inserting the positive terminal of one module
into the negative terminal of the next module.
The number of modules connected in series
or in parallel needs to be reasonably designed
according to the system configuration. All
instructions above must be followed to meet
the Jolywood Warranty valid conditions.
