To use a high electrical current, several PV modules can be connected in parallel, allowing
the total current to equal the sum of the modules' currents.
 组件可提供预制连接器，用于系统的电气连接。电缆线尺寸、类型和温度等参数的选择请参考
相关的规定。
modules can be supplied with prefabricated connectors for electrical connections to the
system. Please refer to relevant regulations for cable size, type, temperature and other
parameters.

所选电缆的横截面积和连接器容量必须满足最大系统短路电流（用于单个组件的电缆线横截面
积推荐为 4mm
2
），否则电缆线和连接器会因为大电流而过热。请注意电缆温度的上限是 85℃,
连接器温度的上限是 105℃。
The cable cross-sectional area and connector capacity selected for a ticket must meet the
maximum system short-circuit current (the recommended cross-sectional area for a cable used
for a single module is 4mm2), otherwise the cable and connector can overheat due to high current.
Please note that the cable temperature upper limit is 85
°
C and the connector temperature
upper limit is 105
°
C.

九、调试和维护
DEBUGGING AND MAINTENANCE
9.1 阻塞二极管和旁路二极管
Blocking diode and bypass diode
 阻塞二极管能够在组件没有电流生成时阻止电流从其他来源流向组件。如果没有使用充电控制
器，则推荐使用阻塞二极管。关于充电控制器请咨询专业经销商。
A blocking diode prevents current from flowing to a module from other sources when no
current is being generated. If a charging controller is not used, a blocking diode is recommended.
Please consult a professional dealer about charging controller.

在由两个以上组件串联的系统中，当组件的一部分被遮挡而其它部分暴露在阳光下时，过高的
反向电流会流经局部或完全被遮挡的电池，导致电池过热甚至会损坏组件。在组件中使用旁路
二极管可以保护组件不受这种过高的反向电流影响。所有额定功率大于55瓦的组件都已在接线
