系统设计需要有防雷击功能，特别是在安装地有较多雷击，一定要更加重视
The tilt angle measurement of the PV module refers to measuring the angle
between the module and the horizontal ground surface. For different projects
there are different mounting angles. Trina Solar recommends that the mounting
tilt angle should be NOT less than 10°, or in accordance with local regulations
or follow the recommendations of experienced PV module installers.
光伏组件的倾角测量指组件与水平地面的角度。针对不同的项目有不同的安装倾
角，天合推荐的组件安装夹角不小于
10°
，或依据当地法规指南或有经验的光伏
组件安装商的建议。
The tilt angle of the PV module is measured between the PV module and a
horizontal ground surface.
通过测量
PV
组件和水平地面之间的夹角来得出
PV
组件的倾斜角测量值。
In the Northern Hemisphere, the PV modules should typically face south, and in
the Southern Hemisphere, the PV modules should typically face north.
在北半球安装，组件最好朝南，在南半球安装，组件最好朝北。
A clearance of at least 115mm (4.5in) (recommended) is provided between
modules and the surface of the wall or roof. If other mounting means are
employed this may affect the UL Listing or the fire class ratings.
应在组件和墙面或屋顶表面之间留有至少
115mm

如果采用其他安装方式，则有可能会影响

认证或防火等级。
Attachment 2: INVERTER SELECTION AND COMPATIBILITY
逆变器的选择及其兼容
性
When installed in systems governed by IEC regulations, Trina Solar modules
normally do not need to be electronically connected to earth and therefore can
be operated together with either galvanically isolated (with transformer) and
transformerless inverters.
当安装在符合
IEC
规定的系统中时，天合光能的组件通常不需要接地，因此可以
与电隔离式的逆变器（带变压器）或无变压器式的逆变器一起工作。
Potential Induced Degradation (PID) is sometimes observed in PV modules due
to a combination of high humidity, high temperature and high voltage. PID is
most likely to cause degradation under the following conditions:
由于高湿度、高温和高电压等综合因素，有时在
PV
组件中会出现电势诱发衰减效
应（

）。
PID
在以下条件下最有可能导致衰减：
o
Installations in the warm and humid climates
在温暖和潮湿的气候条件下安装
o
Installation close to a source of continual moisture, such as bodies of water
在靠近水体等有持续水分来源的地方安装
To reduce the risk of PID, we strongly suggest that modules feature Trina
Solar’s Anti-PID technology, which can be applied to any Trina product.
Alternatively, we recommend the use of an inverter that includes a transformer
as well as proper grounding of the negative DC leg of the PV array.
为降低
