Wire Size - Epever Tracer2206AN User Manual

②At minimum operating environment temperature

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
Please refer to the value of Isc in the PV module specification. When PV modules
connect in series, the Isc is equal to a PV modules Isc. When PV modules connect in
parallel, the Isc is equal to the sum of the PV module's Isc. The Isc of the PV array
must not exceed the controller's maximum PV input current. Please refer to the table
as below:
NOTE: All PV modules in a given array are assumed to be identical.
＊Isc=short circuit current(amps) Voc=open circuit voltage.

＊These are the maximum wire sizes that will fit the controller terminals.
CAUTION: When the PV modules connect in series, the open circuit
voltage of the PV array must not exceed 46V (Tracer**06AN), 92V
(Tracer**10AN) at 25℃ environment temperature.

