N Number of modules in series
表示无串联组件
Voc Open circuit voltage of each module (refer to product label or data sheet)
表示各组件的开路电压（参考产品标签或数据表）
TCvoc Thermal coefficient of open circuit voltage for the module (refer to data sheet)

Each module has two standards 90°C sunlight resistant output cables each
terminated with plug & play connectors. The wire type and gauge of the output
cables are 1500V rated PV Wire cable and are 12AWG in size. This cable is
suitable for applications where wiring is exposed to the direct sunlight. We
require that all wiring and electrical connections comply with the appropriate
National Electrical Code.

接线
To ensure proper system operation the correct cable connection polarity
(Figures 1 & 2) should be observed when connecting the modules to each other
or to a load, such as inverter, a battery etc. If modules were not connected
correctly, the bypass diode could be destroyed. PV modules can be wired in
series to increase voltage. A series connection is made when the wire from the
positive terminal of one module is connected to the negative terminal of the next
module. Figure 1 shows modules connected in series. PV modules can be
connected in parallel to increase current (Figure 2). A parallel connection is
made when the wire from the positive terminal of one module is connected to
the positive terminal on the next module.
为了确保系统正常运行，在连接组件或连接负载（如变频器、电池等）时，应观
察确保电缆的极性连接正确。如果组件连接不正确，旁路二极管可能会损坏。
