QUICK INSTALLATION GUIDE
Installing a Huayu
HY-1000/800-Plus
Microinverter
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
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).
Huayu monitoring data logger connects the microinverter to the
Huayu Portal server via the cloud, allowing for collection of production
and other data useful in system monitoring and trouble shooting.
Users can monitor and manage the microinverter through
corresponding website or APP.

If the PLC signal is weak, it may be significantly improved by moving the data logger to closer to the microinverter arrays, and/or farther away from other interferers,
and/or install a signal filter (LCF) to reduce the interference to PLC communication.
