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.

System Overview

The diagram illustrates a typical photovoltaic system setup. Multiple PV modules are connected to individual microinverters. These microinverters are then wired together and connected to a junction box. From the junction box, the AC power is routed through a meter to a distribution box, which includes neutral and ground connections. The system also shows a router and monitoring system connected via WIFI Boost, indicating wireless communication capabilities.

Technical Data

NOTE: If the wireless signal in the area where the Microinverter is installed is weak, it is necessary to add a wifi signal booster at a suitable place between the router and the Microinverter.

Microinverters Maximize PV Energy Production

This integrated system improves safety; maximizes solar energy harvest; increases system reliability, and simplifies solar system design, installation, maintenance, and management.

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 113°F (45°C). The inverter housing is designed for outdoor installation and complies with the IP67 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 Micro Inverter, potentially eliminating the installation of grounding wire (check local regulation).

Data collection adopts internal wifi; a wireless router is needed near the Microinverter. When complete the installation of 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.

Micro Inverter Introduction

The Microinverters connect with the single-phase grid, and can also use multiple Microinverters in the form of single-phase grid to achieve three-phase grid. For more information, please see the Technical Data page (P16-P17) 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.

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 an Micro Inverter, please read all instructions and warnings in the technical documents and on the Microinverter system itself as well as on the PV array.
• Be aware that installation of this equipment includes the risk of electric shock.

NOTE:

• Strongly recommend to install Surge protection Devices in the dedicated meter box.
• The product is suitable for residential, commercial and light industrial environments, not for industrial environments.

• An or several AC connection junction boxes
• Mounting hardware suitable for module racking
• Sockets and wrenches for mounting hardware
• Continuous grounding conductor and grounding washers
• A Phillips screwdriver
• A torque wrench

Parts list

Please check the following table, to see whether all the parts are included in the package:

* Choose either Bus AC connector or Extension cable with European standard plug; you cannot use them in the same project.

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. Connect the AC branch circuit junction box to the point of utility Grid Interconnection (Usually it is inside a distribution box).

The diagram shows the AC wiring from multiple microinverters connecting to a junction box. The junction box is then connected to a meter and a distribution box, which has connections for Neutral and Ground. The wiring colors are typically Red (L), Black (N), and Yellow (PE).

WARNING: Wiring colour code can be different according to local regulation, 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 and junction box or any other obstructions.

b. Mount one Microinverter at each of these locations using hardware recommended by your module racking vendor.

The Microinverter model shown is M60/80/100 G4 (2MPPT). The AC wire on the Microinverter is a TC-ER wire with a wire cross-section area of 1mm² (18AWG).

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) where exposed to the sun, rain or snow, even gap between modules. Allow a minimum of 3/4 (1.5cm.) between the roof and the bottom of the Microinverter to allow proper air flow.

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. For parallel connection, please refer to page (P18-P19). Use the T-connector, AC extension cable, or Bus AC connector (if only one branch, use the Extension cable with European standard plug) to connect the Microinverter in each branch.

The male connector diagram shows the connection points: PE (Protective Earth), L (Line), and N (Neutral).

WARNING: DO NOT exceed maximum number of Microinverters in an AC branch circuit, as displayed on page 5 of this manual.

The T-connector diagram shows a connector with ports. A port marked with a two-way arrow connects to an extended cable, while a port marked with a one-way arrow connects to a Microinverter.

Step 4 - Connect the wire open of branch end to the junction box.

The diagram shows the final AC connection from the branch end to the junction box.

Step 5 - Connect Microinverter to the PV Modules

General Guidelines:

• a. PV modules should be connected to DC input ports of a Microinverter.
• b. In order to meet the relevant regulatory requirements, the cable length must be <3M. Please consult the local power operator to make sure that the DC cable complies with local regulations.

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

When AC power is applied but the Microinverter has not started up, about 0.1A current and 25VA power for each Micro Inverter 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

Start up LED

One minute after DC power is first applied to the Microinverter, one short red blink indicates 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 seven 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 Microinverter and network has a problem. The items below refer to Microinverter issues, not communication issues:

One quick way to tell whether the issue is the Microinverter or the communication problem:

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 maybe because the server is updating.

Troubleshooting Steps

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 the 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 is functioning properly and is closed.
5. Check the DC connections between the Microinverter and the PV module.
