A PV system by Microinverters is simple to install. Each Microinverter easily mounts on the PV racking system, directly beneath the PV module. 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 so. 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.
Be aware that only qualified professionals should install and/or replace Microinverters.
Before installing or using a Microinverter, please read all instructions and warnings in the technical documents and on the Microinverter itself
as well as on the PV array.
Be aware that installation of this equipment includes the risk of electric shock.
Do not touch any live parts in the system, including the PV array, when the system has been connected to the electrical grid.
Strongly recommend to install surge protection devices in the dedicated combiner box.
Additional Installation Components
AC Male and Female Interconnection Connectors(offered separately)
Sealing end caps(offered separately)
Required Parts and Tools
In addition to your PV array and its associated hardware, the following
items are needed for installation:
An AC connection junction box
Mounting hardware suitable for module racking system
Sockets and wrenches for mounting hardware
Continuous grounding conductor and grounding washers
A Phillips screwdriver
A torque wrench
NOTE:
If the wireless signal in the area for the Microinverter is weak, it is necessary to add a WiFi signal booster at a suitable place between the router and the
microinverter.
This integrated system improves safety; maximizes solar energy harvest; increases system reliability and simplifies solar system design, installation,
maintenance and management.
Simple to Install
You can install individual PV modules in any combination of Module
quantity and orientation, different type and power rate. The Ground
wire (PE) of the AC cable is connected to the chassis inside of the
Microinverter, potentially eliminating the installation of grounding
wire(check local regulation).
Data collection adopts internal WiFi, wireless router is needed near
the Microinverter. When complete the installation of microinverter,
configure wireless router with internal WiFi(refer to the WiFi user
manual). The data will be uploaded automatically. Users can monitor
and manage the microinverter through corresponding website or APP.
