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 snow lines 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 be read in their entirety before installing or commissioning the equipment. For safety, only qualified technicians, who have received training or have demonstrated skills can maintain this microinverter.

System Introduction

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

Balcony Microinverter.
TSUN monitoring system.

The microinverter 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.

Microinverter Installation

Pre-installation Check

Although TSUN 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.
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 microinverter 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.

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 microinverter.

CAUTION ⚠️ If the DC cable is too short for installation, use a DC Extension Cable to connect PV modules 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 module side of DC extension cable.

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