光伏组件安装手册

Automatically all module frames and mounting brackets have to be properly grounded.
Secure the grounding cable to the module frame using the recommended connection terminals.
 使用经过电镀处理的支撑框架，以保证电路导通良好。
buy a ticket using an electroplated support frame to ensure the circuit runs smoothly.

用一适当的接地导体，将该组件框架和支撑构件连接，可做到合适的接地效果。
An appropriate grounding effect can be achieved by connecting the module frame to the
supporting member with an appropriate grounding conductor.

接地导体必须通过一个适当的地面电极连接到地面。推荐使用接地线配件（接线鼻）连接接地
电缆。若没有通过螺栓和螺母连接机械地到已接地的光伏组件上，支架也必须接地。
The ground conductor must be connected to the ground buy an appropriate ground
electrode. You are advised to use a ground cable accessory (wiring nose) to connect the ground
cable. The bracket must also be grounded if it is not mechanically connected to the grounded PV
module by bolts and nuts.
8.3 电气安装通则
General rules for electrical installation

在同一个光伏发电系统上尽量使用相同配置的组件。
buy a ticket to use the same configuration of modules on the same PV system.

几个组件串联，然后并联形成光伏阵列，这特别适用于电压较高的情况下。组件串列的最大串
联数量(N) = Vmax 系统/[Voc(at T)]，T 为实际使用环境温度，单个组串组件开路电压之和应
在组件设计系统电压之内。
Several modules are connected in series and then connected in parallel to form a
PHOTOVOLTAIC array, which is particularly suitable for high voltages. The maximum number of
modules in series (N) = Vmax system /[Voc(at T)], T is the actual ambient temperature, the sum of
the open circuit voltage of each module in series should be within the voltage of the module
design system.

需要使用高电流的情况下，可以将几个光伏组件并联，总电流等于各个组件电流的总和。
