Dear customer, thank you for choosing the Balcony microinverter from TSUN. We hope you will find our products meet your needs for renewable energy. Meantime, we appreciate your feedback regarding our products.

A solar microinverter, or simply microinverter, is a plug-and-play device used in photovoltaics, that converts direct current (DC) generated by a single solar module to alternating current(AC). The main advantage is that small amounts of shading, debris, or snowlines on any single solar module, or even a complete module failure, do not disproportionately reduce the output of the entire array. Each microinverter harvests optimum power by performing maximum power point tracking (MPPT) for its connected module. Simplicity in system design, lower amperage wires, simplified stock management, and added safety are other factors introduced with the microinverter solution.

This manual contains important instructions for Balcony microinverters and must bread in their entirety before installing or commissioning the equipment. For safety, only qualified technicians, who have received training or have demonstrated skills can install and maintain this microinverter under the guide of this document.

Important Safety Information

System Introduction

The Balcony micro inverter is used in grid-tied applications, comprised of two key elements:

Balcony Microinverter.
TSUN monitoring system.

The micro inverter converts the DC electricity generated by solar panels into AC electricity which is in accordance with the requirements of the public grid and sends the AC into the grid, reducing the load pressure of the grid.

TSOL- MX400 Balcony
TSOL-MX450 Balcony
TSOL-MX500 Balcony

The micro inverter is integrated with the Wi-Fi module and connects to the home Wi-Fi router directly. Users can monitor the power generation of the system by TSUN monitoring App.

Microinverter Installation

Pre-installation Check

Check the Package

Although TSUN’s microinverters have surpassed stringent testing and are checked before they leave the factory, it is uncertain that the microinverters may suffer damage during transportation. Please check the package for any obvious signs of damage, and if such evidence is present, do not open the package and contact your dealer as soon as possible.

Check the Installation Environment and Position

When choosing the position of installation, comply with the following conditions:

To avoid unwanted power derating due to an increase in the internal temperature of the inverter, do not expose it to direct sunlight.
To avoid overheating, always make sure the flow of air around the inverter is not blocked.
Do not install in places where gasses or flammable substances may be present.
Avoid electromagnetic interference that can compromise the correct operation of electronic equipment.
It’s recommended to install micro inverter on structures underneath the photovoltaic modules so that they work in the shade.
Use a mobile phone to check the Wi-Fi signal strength at the installation position. If the Wi-Fi signal is bad, try to install the micro inverter in another position or move the Wi-Fi router.

Installation Steps

DANGER

· Before installation, check the unit to ensure the absence of any transport or handling damage, which could affect insulation integrity or safety clearances.

· Unauthorized removal of necessary protections, improper use, incorrect installation, and operation may lead to serious safety and shock hazards or equipment damage.

· Be aware that installation of this equipment includes the risk of electric shock.

Step 1. Install the bracket.

WARNING

· Choose the installation location carefully and adhere to specified cooling requirements. Micro-inverter should be installed in a suitable position with good ventilation and no direct sunshine.

· Please use your mobile phone to check the WiFi signal strength at the installation location, ensuring that the WiFi signal is at least two bars. If the WiFi signal is not good, please try installing the mini inverter in another location or moving the WiFi router.

Balcony Installation

Choose a suitable position, fix the buffer strip on the railing, and then use stainless steel rolling strip to fix the bracket.

Wall Installation

Fix the bracket to the wall with screws in a suitable position.

Step 2. Connect the ground cable

DANGER

· Do not install the equipment in adverse environment conditions such as flammable, explosive, corrosive, extreme high or low temperature, and humid.

Balcony Installation

Using two pairs of screws and nuts to fix the microinverter on the frame. Make sure that the label of microinverter should be upside.

Wall Installation

Using two pairs of screws and nuts to fix the micrio inverter on the frame. Make sure that the label of microinverter should be upside.

Step 3. Connect the ground cable.

****WARNING

· Ensure that all the micro inverters are well grounded.

· Use ɸ6 screw for the ground port.

Connect the ground cable to the enclosure of the microinverter.

Step 4. Connect AC end cable

DANGER

· Ensure that all AC cables are correctly wired and that none of the wires are pinched or damaged.

· Use AWG 16 (1.5 mm²) cable for AC end cable.

CAUTION

· The AC connecters may be provided by different suppliers. The port definitions are subject to actual objects.

Separate the AC connector as shown below.

Get the AC cable through the shell of AC connector and connect the cable to the right port.

The definition of the port is shown below:

Reassemble the AC connector as shown below.

Plug the AC connector into the microinverter and connect the AC cable to the AC distribution box.

Step 5. Connect the DC Cable

DANGER

· When the photovoltaic array is exposed to light, it provides a DC voltage to the inverter.

WARNING

· Ensure that all DC cables are correctly wired and that none of the wires are pinched or damaged.

· The maximum open circuit voltage of the PV module must not exceed the specified maximum input DC voltage of the TSOL micro inverter.

CAUTION

· If the DC cable is too short for installation, use a DC Extension Cable to connect PVmodules to the microinverter.

· Use MC4 compatible DC connectors in the inverter side of the DC extension cable, or get the DC connectors from TSUN.

· Contact PV module manufacturers for the requirements of the DC connectors in the moduleside of DC extension cable.

Install the PV modules and connect the DC cable to the microinverter.

Step 6. Start the System

CAUTION

Do not connect micro-inverters to the grid or energize the AC circuit(s) until you have completed all the installation procedures and have received prior approval from the electrical utility company

While installation is all finished, After plugging in the socket and connecting to the power supply. Your system will start producing power after about a two-minute wait time.

The LED will flash green and red at start-up. The definition of LED is shown below.

Status	Indicates
Flashing Green (0.2-0.8s )	Working normally
Flashing Red	Working abnormally
Solid Red	Fault

Remote Active Power Control

In some countries, it might be required that the generating plants should be equipped with a logic interface (input port) to cease the output of active power or limit active power to a regulated level. This logic input can be the RS485 port, Ethernet port, and so on. TSUN microinverter provides an extra power control device that contains an RS485 port for this remote active power control. For more information, refer to the “User Manual of TSUN power control device”.
