Microinverter System Installation
A PV system using Microinverters is simple to install. Each Microinverter easily mounts
on the PV racking, directly beneath the PV module(s). Low voltage DC wires connect
from the PV module directly to the Microinverter, eliminating the risk of high DC
voltage.Installation MUST comply with local regulations and technical rules.
Special Statement! An AC GFCI device should not be used to protect the dedicated circuit
to the microinverter even though it is an outside circuit. None of the small GFCI devices
(5~30mA) are designed for back feeding and will be damaged if back feed. In a similar
manner, AC AFCIs have not been evaluated for back feeding and may be damaged if back
feed with the output of a PV inverter.
WARNING: Perform all electrical installations in accordance with local electrical codes.
WARNING: Be aware that only qualified professionals should install and/or replace
Microinverters.
WARNING: Before installing or using an Microinverter,please read all instructions and
warnings in the technical documents and on the Microinverter system
itself as well as on the PV array.
WARNING: Be aware that installation of this equipment includes the risk of electric
shock.
Additional Installation components
· AC Male and Female Interconnection Connectors (sold separately)
· Sealing end caps(sold separately)
NOTE: Strongly recommend to install Surge protection Devices in the dedicated meter
box.
Required Parts and Tools from you
In addition to your PV array and its associated hardware, you will need the following
items:
· An AC connection junction box
· Mounting hardware suitable for module racking
· Sockets and wrenches for mounting hardware
· Continuous grounding conductor and grounding washers
