Microinverter System Introduction

The Microinverter is used in utility-interactive grid-tied applications, comprised of two key elements:

• Microinverter
• Router
  This series microinverter has built-in WIFI module so it can communicate with router directly.

300 / 500 / 600 / 800 / 1000G3

1300 / 1600 / 1800 / 2000G3

NOTE: If the wireless signal in the area where the microinverter is weak 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.

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, wireless router is needed near the microinverter. When complete the installation of the 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 the corresponding website or APP.

Microinverter Introduction
The Microinverters connect with the single-phase grid, and can also use multiple Micro-inverters 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:
Use the DC power connector of the accessories. Do not interconnect the connectors of different manufacturers.

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 minutes 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 wifi module to the network every 5 minutes.It enables customers to monitor performance data of each microinverter through website and APP.

NOTE: When AC power is applied but the microinverter 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 by 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:

1. The Microinverter itself may be having problems.
2. The Microinverter itself is working fine but the communication between microinverter and network has problem. The items below refer to Microinverter issues, not communicating – 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

Diagnosing from the network:

1. No-Data-Display: The website and APP don’t display any data.Check the network configuration.
2. Only display microinverter is online but no data.This maybe because 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 breaker 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
