installation, dismantling, maintenance and any other related process of the Product.
安装需注意事项：为了将间接雷击的风险降到最低，在设计系统时应避免形成回路。为避免人为因素造成线缆
与连接器、线缆与接线盒连接不良或损坏，影响产品电气安全或使用寿命，建议产品在安装、拆卸、维护及任何其
它相关过程中，施加在线缆和连接器、线缆和接线盒之间的作用力不得大于
60N
。
Pay attention to the direction of the wire when installing the modules. It should be connected along the wire
direction to avoid bending the wire.
注意组件安装时的导线方向，应顺着导线方向连接，避免导线折弯。

The Direct Current (DC) generated by the PV system can be converted to Alternating Current (AC) and
connected to the public power grid. Different regions may have different policies, laws and regulations to stipulate
the installation and grid-connection requirements of PV systems. Therefore, during the design, installation and
grid-connection of PV system, please comply with the local policies, laws and regulations.
光伏系统产生的直流电可以转换成交流电，并与公共电网相连。不同地区可能有不同的政策和法律法规来规定
光伏系统的安装要求和并网要求，因此在光伏系统的设计、安装和并网过程中，请遵守当地的政策和法律法规要求。
PV modules can obtain different current and voltage outputs through series connection and parallel
connection. Read this installation manual carefully before electrical connection and installation. Please design and
connect according to the current and voltage required by customers. Before connection, please ensure that the
connection part is free from corrosion, and keep it clean and dry.
光伏组件通过串联和并联的连接方式可以获得不同的电流和电压输出，在进行电气连接和安装前，请仔细阅读
本安装手册，并依据客户所要求的电流和电压进行设计和连线。连接前请确保连接部分无腐蚀，保持清洁和干燥。
Different types of modules cannot be connected in series. Modules connected in series should ensure the
consistency of their current. The voltage of the module string should not exceed the allowable system voltage
value, which can be found on the nameplate or datasheet of the module.
不同类型的组件产品不能串联在一起，串联在一起的组件产品要保证其电流的一致性，组件串的电压不能超过
所允许的组件系统电压值，该电压值可以在组件的铭牌或者规格书里找到。
Sunpro Power modules are provided with stranded copper cables with a cross sectional area of 4mm ²
which are rated for 1500V dc, 90°C and are UV resistant. All other cables used to connect the DC system should
have a similar (or better) specification. Sunpro Power recommend that all cables are run in appropriate conduits
and sited away from areas prone to water collection.

建议将所有电缆铺设在适当的导管中，并
远离容易积水的区域。
The maximum number of modules in series depends on the system design, the type of converter used and
the environmental conditions. In general, the maximum number (N) of PV modules in series can be calculated by
dividing the maximum system voltage by the open circuit voltage of the relevant
Solar PV modules. When
designing the Solar PV system, it is necessary to take into account the characteristic that the voltage of the
Solar PV module changes with the temperature. Considering the voltage increase caused by temperature drop in
extreme environment in winter, the maximum series connection number of Solar PV modules can be calculated
by the following formula.
串联组件的最大数目取决于系统设计、所用变频器的类型和环境条件。通常情况下，最大的串联太阳能光伏组
件数量（
N
）可以通过系统最大电压除以相关太阳能光伏组件开路电压的方式计算而获得，但是在设计太阳能光伏
系统时，一定要考虑到太阳能光伏组件的电压随着温度变化而变化的特性。考虑到冬季里极端环境下温度下降造成
