Only use electrical system components approved for wet locations.
Only qualified personnel should install, troubleshoot, or replace Enphase Microinverters or
Enphase Q Cable and Accessories.
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.
Do not use Enphase equipment in a manner not specified 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.
Before installing or using the Enphase Microinverter, read all instructions and cautionary markings
in the technical description, on the Enphase equipment and on the photovoltaic (PV) equipment.
Do not connect Enphase Microinverters to the grid or energize the AC circuit(s) until you have
completed all of the installation procedures and have received approval from the electrical utility
company.
When the PV array is exposed to light, DC voltage is supplied to the power conversion equipment
(PCE).
Risk of equipment damage. Enphase male and female connectors must only be mated with the
matching male/female connector.
To ensure optimal reliability and to meet warranty requirements, install the Enphase equipment
according to the instructions in this manual.
The AC and DC connectors on the cabling are rated as a disconnect only when used with an
Enphase Microinverter.
Protection against lightning and resulting voltage surge must be in accordance with local
standards.
Perform all electrical installations in accordance with all applicable local electrical codes, such as:
the Canadian Electrical Code, Part 1; ANSI requirements; and NPFA 70 (NEC).
The body of the Enphase Microinverter is the heat sink. Under normal operating conditions, the
temperature could be 20° C above ambient, but under extreme conditions the microinverter can
reach a temperature of 90° C. To reduce risk of burns, use caution when working with
microinverters.
Only qualified personnel may connect the Enphase Microinverter to the utility grid.
Do not attempt to repair the Enphase Microinverter; it contains no user-serviceable parts. If it fails,
contact Enphase customer service to obtain a return merchandise authorization (RMA) number
and start the replacement process. Tampering with or opening the Enphase Microinverter will void
the warranty.
The Enphase Microinverter is not protected from damage due to moisture trapped in cabling
systems. Never mate microinverters to cables that have been left disconnected and exposed to
wet conditions. This voids the Enphase warranty.
The Enphase Microinverter has field-adjustable voltage and frequency trip points that may need
to be set, depending upon local requirements. Only an authorized installer with the permission
and following requirements of the local electrical authorities should make adjustments.
