2.3 Wire Size

The wiring and installation methods must conform to national and local electrical code
requirements.
PV Wire Size
The PV array output varies with the PV module size, connection method, or sunlight angle. The PV
array Isc can calculate the minimum wire size. Please refer to the value of Isc in the PV module
specification. When PV modules are connected in series, the Isc equals the PV module Isc. When
PV modules are connected in parallel, the Isc equals 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
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.
When the PV modules are connected in series, the open-circuit voltage of the
PV array must not exceed 46V (TRIRON**06N), 92V (TRIRON**10N), or 92V
