DANGER
Installation of this equipment carries risk of electrical shock. Use insulated tools to reduce risk of electric
shock. Do not touch terminals with bare hands.
Do not disconnect modules while under load. Do not disconnect cables while the system is in operation.
Only qualied personnel should install, troubleshoot, or replace Solaria PowerXT
®
-R-AC Modules or
Enphase Q Cable and Accessories.
Always de-energize AC branch circuit before performing service.
Ensure that all AC junction boxes are properly closed.
Do not install or handle modules when they are wet or during periods of high wind.
Do not install or use equipment in a manner not specied by the manufacturer.
Only use electrical system components approved for wet locations.
Ensure that all AC and DC wiring is correct and that none of the AC or DC wires are pinched, shorted or
damaged. Ensure that all AC junction boxes are properly closed.
Do not exceed the maximum number of microinverters in an AC branch circuit as listed in the manual. You
must protect each microinverter AC branch circuit with a 20 A maximum breaker or fuse as appropriate.
DANGER:
Risk of
electric
shock.
Installation must be performed in accordance with the local and national electrical codes.
Avoid all electrical hazards when installing, wiring, operating, and maintaining a module or module array.
The system must be installed, commissioned and maintained by a licensed electrician unless local
electrical codes determine otherwise.
Do not use modules of different electrical or physical congurations in the same circuit or system.
Measure AC voltage of the grid at the distribution panel and ensure it matches with the rating of the module
being installed.
Metal clips specically designed to be used for the AC cable is to be used in accordance with the
manufacturer’s instructions.
Module junction boxes or junction box cables should not be used to attach other wiring or other
components.
Match the polarities of the cables and terminals when making connections; failure to do so may result in
damage to the modules and other electrical equipment.
A properly rated and certied over-current device must be connected in each branch circuit.
All Solaria modules are factory supplied with bypass diodes located in the junction box.
The microinverter and junction box are not designed or certied to be eld accessible or maintainable and
should under no circumstances be opened. Opening the microinverter or the junction box will void the
module warranty.
Do not use Enphase equipment in a manner not specied by the manufacturer. Doing so may cause death
or injury to persons, or damage to equipment.
Be aware that installation of this equipment includes risk of electric shock.
The DC conductors of this photovoltaic system are ungrounded and may be energized.
Always de-energize the AC branch circuit before servicing. Enphase does not recommend disconnecting the
DC connectors under load.
