2.3 Wire Size

The wiring and installation methods must conform to all national and local electrical
code requirements.

PV Wire Size
Since PV array output can vary due to the PV module size, connection method or
sunlight angle, the minimum wire size can be calculated by the Isc of PV array.
Please refer to the value of Isc in PV module specification. When the PV modules
connect in series, the Isc is equal to the PV module‟s Isc. When the PV modules
connect in parallel, the Isc is equal to the sum of PV module‟s Isc. The Isc of PV array
must not exceed the maximum PV input current, please refer to the table as below:

NOTE: When the PV modules connect in series, the open circuit voltage of the PV
array must not exceed 92V (25℃)

Battery Wire Size
The battery and load wire size must conform to the rated current, the reference size
as below:

NOTE: The wire size is only for reference. If there is a long distance between the PV
array and the controller or between the controller and the battery, larger wires can
be used to reduce the voltage drop and improve performance.
