A label providing details on each connector and torque requirements for each

terminal is affixed to the inside of the wiring compartment cover plate.

Wire Size and Over-current Protection Requirements

PV Current Rating

The maximum PV array input current specification is 28 A I

at STC. The gauge

of PV wiring must coordinate with local electrical code requirements and the total

array short circuit current, based on the published I

rating of the PV panels

installed in the system.

Minimum Wire Gauge

For installations where the PV array is specified at the 35 A maximum, the

recommended smallest wire size is #8 AWG (10 mm

)

copper wire with a 75 °C

(167 °F) insulation rating. The wire gauge requirements vary with those of the

local jurisdiction. For details, consult the electrical code.

WARNING

HAZARD OF ELECTRIC SHOCK, ENERGY, AND FIRE

The wiring, over-current protection devices (fuses and circuit breakers), and

installation methods used must conform to all national and local electrical

code requirements. Wiring must be protected from physical damage with

appropriate methods such as the use of conduit and strain relief clamps.

To prevent intermingling with hazardous voltage-level wiring, the BTS, auxiliary

output, and network cables must pass through a different conduit than the PV

and battery cables.

Failure to follow these instructions can result in death or serious injury.
