ELECTRICAL INSTALLATION
CAUTION: AVOID ALL ELECTRICAL HAZARDS WHEN INSTALLING, WIRING,
OPERATING, AND MAINTAINING A MODULE OR MODULE ARRAY.
Refer to Section 2 for more information.
▲
The electrical installation must be in accordance with CSA C22.1, Safety Standard for Electrical
Installations, Canadian Electrical Code, Part 1.
▲
Recommended Wire:
Single conductor cable, type USE-2 (non-conduit) 10-12AWG (4-6mm
2
) with
minimum 90
º
C rating and sunlight UV protected.
▲
Series Connection:
Modules may be wired in series to produce the desired voltage output. DO NOT
exceed the maximum system voltage indicated on the module label.
▲
Parallel Connection:
Modules may be combined in parallel to produce the desired current output.
It may be necessary to fuse each series string or module prior to combining with other strings. DO
NOT exceed the maximum system voltage indicated on the module label.
▲
Connection cables and wiring must be supported with cable ties and clips to the module support
structures. DO NOT use module junction boxes to support cables and wiring.
▲
Under normal conditions, a photovoltaic module is likely to experience conditions that produce more
current and/or voltage than reported at Standard Test Conditions. Accordingly, the values of Isc and
Voc marked on the module should be multiplied by a factor of 1.25 when determining component
voltage ratings, conductor capacities, fuse sizes, and sizes of controls connected to the PV output.
▲
An additional multiplying factor of 125% (80% de-rating) may be applicable. Refer to section 690-8
of the National Electric Code (NEC) for more information.
▲
All Solaria modules are equipped with factory locking connecting cables. Modules have been
designed to be easily connected. DO NOT disconnect the locking connectors
under load.
The proper procedure to disconnect the module locking connectors is as follows:
1. Turn off of the inverter(s).
2. Shut off the module DC disconnect(s).
3. Disconnect the locking connectors using the Multi-Contact tool set, Part Number PV-MS.
To re-install:
1. Connect the module locking connectors.
2. Turn on the module DC disconnect(s).
3. Turn on the inverter(s).
