throughout this document to indicate dangerous conditions and important safety considerations.
Specifications are subject to change without notice - please ensure you are using the most recent update
found at the manufacturer website.
WARNING SYMBOL: Indicates a situation where failure to follow instructions
appropriately may cause a serious hardware failure or personal injury. Use extreme
caution when performing this task.
WARNING
SYMBOL
NOTE SYMBOL: Displays information that is important for optimized microinverter
operation. Follow these instructions closely.
Safety Instructions
Do NOT disconnect the PV module from the Microinverter without
first disconnecting the AC power.
NOTE
SYMBOL
Only qualified professionals should install and/or replace the Microinverters.
Perform all electrical installations in accordance with local electrical codes.
Before installing or using the Microinverter, please read
all instructions and cautionary markings in the technical documents and on the Microinverter
system and the solar-array.
Be aware that the body of the Microinverter is a heat-sink, and can reach temperatures
close to 80°C. To reduce risk of burns, do not touch the body of the Microinverter.
DO NOT attempt to repair the Microinverter. If it fails, contact Customer Support to obtain an
RMA number and start the replacement process. Damaging or opening the Microinverter will
void the warranty.
Caution!
The external protective grounding conductor is connected to the inverter grounding
terminal through AC connector.
For connection: Connect the AC connector first to ensure inverter grounding, then
perform the DC connections.
When disconnecting: First disconnect the AC connector by opening the branch circuit breaker,
with the protective grounding conductor still connected. Disconnect the DC inputs afterwards.
In any circumstance, do not connect DC input when the AC connector is unplugged.
Please install isolation switching devices on the AC side of the inverter.

Radio Interference Statement
CE EMC Compliance：The equipment complies with CE EMC, which is designed to protect against
harmful interference in residential installations. The equipment could emit radio frequencies
which might cause harmful interference with radio communications, if the following
installation instructions are not adhered to. There is no guarantee that interference will not
occur in a particular installation. If this equipment causes hindering interference to radio
or television reception, the following measures might resolve the issue:
a) Relocate the receiving antenna, and keep it well away from the equipment.
b) Consult the dealer or an experienced radio / TV technician for further assistance.
Changes or modifications not approved by the party responsible for compliance may void the user’s
authority to operate the equipment.
Communication Statement
The Energy Monitoring system and Analysis (EMA) software analyses and reports the performance
of each module using real-time data, which is collected through the Data Monitoring Unit (DMU)
gateway. The EMA promptly detects any performance issues in the array, pinpointing the
location and nature of the problem and providing precise guidance for maintenance, all within a
user-friendly graphic interface.
Communication between inverters and the DMU may be affected by signal “noise” from nearby
electrical equipment, the distance between inverters and the DMU, the number of inverters
supported, as well as other factors. If the DMU experiences a random loss of signal or data, an error
or problem did not occur. If the DMU does not communicate with the EMA database at all, contact
support.

Microinverter System Introduction
This integrated system improves safety, maximizes solar energy harvest, and increases system
reliability. It also simplifies solar system design, installation, maintenance, and management.
Microinverters maximize PV energy production
Each PV module has individual Maximum Peak Power Tracking (MPPT) controls, which ensures that
the maximum power is transmitted to the utility grid regardless of the performance of the other PV
modules in the array. When PV modules in the array are affected by shade, dust, orientation, or
any situation in which one module under performs compared with the other units, the
microinverter ensures peak performance from the array by maximizing the performance of each
module.
More reliable than centralised or string inverters
The distributed microinverter system ensures that no single point of failure exists across the PV
system. Microinverters are designed-to operate at maximum power within ambient outdoor
temperatures, including up to 149°F (65°C). The inverter housing is designed for outdoor installation
and complies with the IP65 environmental enclosure rating.
Simple to install
Individual PV modules can be installed in any combination of Module quantity, orientation,
different type and power rate. The ground wire (PE) of the AC cable is connected to the chassis
inside the microinverter. This may potentially eliminate the installation of a grounding wire (check
this with local regulation).
Smart system performance monitoring and analysis
The Data Monitoring Unit (DMU) is installed by simply plugging it into any wall outlet, and providing
an Ethernet connection to a broadband router or modem. After installing and setting-up the DMU
(see DMU manual), the full network of microinverters automatically reports to the Energy Monitor
and Analysis (EMA) web server. The EMA software displays performance trends, alerts the user to
abnormal events, and controls system shutdown when required (See DMU manual for instructions.)

Microinverter Introduction
The microinverters connect with the single-phase grid. A three-phase grid can also be achieved
through the use of multiple microinverters, which operates with most 60 and 72 cell PV modules.

Microinverter System Installation
Setting up microinverters for a PV system is simple. 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 risks associated with 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 (5mA-30 mA)
are designed for back feeding, and will be damaged. 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 a microinverter, please read all instructions
and warnings in the technical documents, 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.
WARNING: Do not touch any live parts in the system, including the
PV array while the system is connected to the electrical grid.
NOTE: It is strongly recommend to install surge protection devices in the
dedicated meter box.

Step 1 - Install the AC branch circuit junction box
a) Install an appropriate junction box at a suitable location on the PV
racking system (typically at the end of a branch of modules).
b) Connect the open wire end of the AC cable into the junction box
using an appropriate gland or strain relief fitting.
c) Wire the conductors of the AC: L - RED; N - BLACK ;
PE - YELLOW GREEN.
d) Connect the AC branch circuit junction box to the point of utility
interconnection.
WARNING: The wiring colour code can be different according local regulation. Check
that all of the installed wire colours match regulation before connecting the AC cable.
Wrong cabling can irreparably damage the microinverters. This error is not covered by
the warranty.
Step 2 - Attach the Microinverters to the racking or the PV
module frame
a) Mark the location of the microinverter on the rack,with respect to the
PV module junction box, or any other obstructions.
b) Mount one microinverter at each of these locations, using the
hardware recommended by your module racking vendor.
