Microinverter System Introduction

The Microinverter is used in utility-interactive grid-tied applications, comprised of three key elements: Microinverter, MECD, Router.
There’ re two kinds of communication method, PLC or Zigbee, for this series microinverter.
This series microinverter needs to connect MECD for remotely monitoring. For more information about MECD please refer to the “MECD User Manual”
300 / 500 / 600 / 800 / 1000G3

1300 / 1600 / 1800 / 2000G3 NOTE: If the wifi signal in the area where the MECD is weak, it is necessary to add a wifi signal booster at a suitable place between the router and the MECD. This integrated system improves safety; maximizes solar energy harvest; increases system reliability, and 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 exported 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 underperforms compared with the other units, the Microinverter ensures top performance from the array by maximizing the performance of each module within the array.
More Reliable than Centralized or String Inverters
The distributed Microinverter system ensures that no single point of system failure exists across the PV system. Microinverters are designed to operate at full power at ambient
outdoor temperatures of up to 149 ℉ (65 ℃). The inverter housing is designed for outdoor installation and complies with the IP65 environmental enclosure rating.
Simple to Install
You can install individual PV modules 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 of the Microinverter, potentially eliminating the installation of grounding wire (check local regulation). Data collection adopts internal wifi, a wireless router is needed near the microinverter.When completing the installation of the microinverter, configure the 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 the corresponding website or APP.
Microinverter Introduction
The Microinverters connect with the single-phase grid, and can also use multiple Microinverters in the form of a single-phase grid to achieve a three- phase grid.
For more information, please see the Technical Data page (P17~20) of this manual.

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 a Microinverter, please read all instructions and warnings in the technical documents and on the Microinverter system itself as well as on the PV array.

Installation Procedures

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(230/400Vac): L – red; N – black ; PE – yellow-green. d. Connect the AC branch circuit junction box to the point of the utility Interconnection.
WARNING: Wiring color codes can be different according to local regulations, check all the wires of the installation before connecting to the AC cable to be sure they match. Wrong cabling can damage irreparably the microinverters, such an issue 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 hardware recommended by your module racking vendor.
WARNING: Prior to installing any of the microinverters, verify that the utility voltage at the point of common connection matches the voltage rating on the microinverter label.
WARNING: Do not place the inverters (including DC and AC connectors) were exposed to the sun, rain or snow, even a gap between modules. Allow a minimum of 3/4 (1.5cm.) between the roof and the bottom of the Microinverter to allow proper airflow.
Step 3- Connect the Microinverters in parallel

a. Check the Microinverter technical data page 5 for the maximum allowable number of Microinverters on each AC branch circuit.
b. Plug the male AC connector of the Microinverter into the female connector to get it connected.AC connector interface as follows.

WARNING: DO NOT exceed the maximum number of Microinverters in an AC branch circuit, as displayed on page 5 of this manual.
Step 4 – Install an AC cable protective end cap at the end of the AC cable

**Step 5 – Connect Microinverter to the PV Modules**

NOTE: When plugging in the DC cables, if AC is already available, the Microinverter should immediately blink red light and will start work within the setting time (default 60 seconds). If AC is not available, the red light will blink 3 times quickly and repeat after one second until AC is connected.

Microinverter System Operating Instructions

To operate the microinverter PV system:

1. Turn ON the AC circuit breaker on each microinverter AC branch circuit.

2. Turn ON the main utility-grid AC circuit breaker. Your system will start producing power after a one-minute waiting time.

3. The units should start blinking red one minute after turning on the AC circuit breaker. Then blue led blinking. This means they are producing power normally, the faster
   blinking of the blue led means more power generated.

4. Configure the internal wifi module according to its user manual.

5. The Microinverters will start to send performance data over the wifi module to the network every 5 minutes.It enables customers to monitor the performance data of each microinverter through the website and APP.

NOTE: When AC power is applied but the microinverter is not started up, about 0.1A current and 25VA(W) power for each microinverter may be measured by a power meter. This power is reactive power, not consumed from the utility grid.

Troubleshooting

Qualified personnel can use the following troubleshooting steps if the PV system does not operate correctly:
Status Indications and Error Reporting
Startup LED
One minute after DC power is first applied to the microinverter, one short red blinks indicate a successful microinverter startup sequence, be equal or greater than two short red blinks after DC power is first applied to the microinverter indicate a failure during microinverter setup.

Operation LED

Flashing Slow Blue – Producing small power
Flashing Fast Blue – Producing big power
Flashing Red – Not producing power
Red blinking two times – AC low-voltage or high-voltage
Red blinking three times – Grid failure

GFDI Error
A four-time red LED indicates the Microinverter has detected a Ground Fault Detector Interrupter (GFDI) error in the PV system.
Unless the GFDI error has been cleared, the LED will remain four times blinking.
Other Faults
All other faults can be reported to the website and APP.
WARNING: Never disconnect the DC wire connectors under load. Ensure that no current is flowing in the DC wires prior to disconnecting. An opaque covering may be used to cover the module prior to disconnecting the module.

Troubleshooting a non-operating Microinverter

There are two possible overall areas of trouble:
A. The Microinverter itself may be having problems.
B. The Microinverter itself is working fine but the communication between the microinverter and network has a problem. The items below refer to Microinverter issues, not communicate -ion issues:
One quick way to tell whether the issue is the Microinverter or the communication problem:
1. Diagnosing from the Microinverter: A red light–either blinking or solid on the Microinverter or no light at all means it is definitely the Microinverter problem.
2. 0 watts, or 2 watts: Possibly a Microinverter problem

2. Diagnosing from the network:
a. No-Data-Display: The website and APP don’t display any data. Check the network configuration.
b. Only display microinverter is online but no data. This may be because the server is updating.
To troubleshoot a non-operating Microinverter, Follow the steps below in order:

1. Verify the utility voltage and frequency are within ranges shown in the Technical Data section of this manual.

2. Check the connection to the utility grid. Disconnect AC firstly, then disconnect DC and make sure the utility grid voltage can be measured at AC connector. Never disconnect
   the DC wires while the microinverter is producing power. Re-connect the DC module connectors and watch for three short LED flashes.

3. Check the AC branch circuit interconnection between all the microinverters. Verify each inverter is energized by the utility grid as described in the previous step.

4. Make sure that any AC breakers are functioning properly and are closed.

5. Check the DC connections between the microinverter and the PV module.

6. Verify the PV module DC voltage is within the allowable range shown in the Technical Data of this manual.

7. If the problem still persists, please contact technical support.

WARNING: Do not attempt to repair the microinverter.If troubleshooting methods fail, please call for Technical Support
