5.2.7 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.
5.2.7.1 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).
a)
The maximum rating of the fuse
connected in series is 25A, and the
module-specific ratings are available on the
product label and product data sheet.
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.
Modules in array should be regularly inspected to
check damage modules. If damage module is
the component open circuit voltage;
Tmin represents the minimum ambient
temperature;
