PV wire size
The PV array's output current varies with its size, connection method, and sunlight angle. The minimum
wire size can be calculated by its ISC (short circuit current). Please refer to the ISC value in the PV
module's specifications. When the PV modules are connected in series, the total ISC equals any PV
module's ISC. When the PV modules are connected in parallel, the total ISC equals the sum of the PV
module's ISC. The PV array's ISC must not exceed the controller's maximum PV input current. For max.
PV input current and max. PV wire size, please refer to the table as below:
When the PV modules are connected in series, the total voltage must not exceed the
max. PV open circuit voltage 46V(Tracer**06AN) or 92V(Tracer**10AN) at 25℃
environment temperature.
Battery and Load Wire Size
The battery and load wire size conform to the rated current, the reference size as below:
The wire size is only for reference. Suppose there is a long distance between the
PV array and the controller or between the controller and the battery. In that
case, larger wires can be used to reduce the voltage drop and improve
