The number of modules in series and in parallel shall be designed reasonably
according to the system configuration.

5.2.5 FUSING
熔丝
When fuses are fitted they should be rated for the maximum DC voltage and
connected in each, non-grounded pole of the array (i.e. if the system is not
grounded then fuses should be connected in both the positive and negative
poles).
在安装熔丝时应将其额定为最大直流电压并连接到阵列的每个非接地极上（换言
之，如果系统没有接地则应将熔丝连接到正负极上）。
The maximum rating of a fuse connected in series with an array string is
typically 20A but the actual module specific rating can be found on the product
label and in the product datasheet.
与阵列串联连接的熔丝的最大额定值通常为
20A
，但实际的组件特定额定值可在
产品标签和产品数据表中获得。
This fuse rating value also corresponds to the maximum reverse current that a
module can withstand (when one string is shaded then the other parallel strings
of modules will be loaded by the shaded string and current will flow) and
therefore impacts the number of strings in parallel.
该熔丝的额定值也对应于组件可承受的最大反向电流值（当一个阵列被遮蔽时，
该阵列会加载到其他并联的组件阵列生成电流），因此会对并列连接阵列的数量
产生影响。
Do NOT share a fuse in a Combiner Box with two or more strings in parallel
connection.
禁止两串或多串并联后再接熔丝。
