Product Usage Instructions

Choose a well-ventilated location with no direct sunlight. Secure the microinverter using screws and nuts provided in the package. Ensure the label is positioned correctly.
Retrieve the AC connector from the package and connect the AC cable to the correct port on the microinverter. Reassemble the AC connector and plug it into the microinverter. Connect the other end to the AC distribution box.
Install the PV modules and connect the DC cable to the microinverter. For TSOL-MS3000, each DC input can connect two PV modules in series.
Paste the provided SN labels on the installation map and complete the information of the solar plant.
Follow the user guidance on the monitoring app (Talent Home) to complete all operations and start the system.
Visit Google Play or Apple Store, search for “Talent Home,” and download it to your mobile phone. Scan the QR code for user guidance.

FAQ

Q: Can I install the microinverter in extreme temperature conditions?
A: It is not recommended to install the microinverter in extreme temperature conditions. Ensure a suitable installation location with proper ventilation.
Q: How long does it take for the system to start producing power after installation?
A: After completing the installation, turn on the main utility-grid AC circuit breaker. The system will start producing power after about a two-minute wait time.
Q: How do I know if the system is working normally?
A: The LED on the microinverter will flash green and red at startup. A solid green LED indicates normal operation, while a solid red LED indicates a fault.

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 a microinverter 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 microinverter at another position or move the Wi-Fi router.

Installation Steps

DANGER

Only qualified personnel should install, troubleshoot, or replace TITAN micro inverters or the cable and accessories.
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 risk of electric shock.

Step 1. Fix the microinverter

DANGER

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

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.

CAUTION

There are no screws and nuts in the package.

Choose an installation position. Using two pairs of screws and nuts to fix the microinverter on the frame. Make sure that the label of the microinverter is upside.

Microinverter can also be installed on the wall. Use the bracket (optional) and fix it on the wall. Then using two pairs of screws and nuts to fix the microinverter on the bracket. Make sure that the label of the microinverter should be outside.

Step 2. Connect the AC cable

DANGER

Do not install the AC junction box without first removing AC power from the system.
To prevent electrical hazards, make sure the micro-inverter system is disconnected from the home distribution network and the AC breaker is open.

WARNING

Ensure that all AC cables are correctly wired and that none of the wires are pinched or damaged.
Use AWG 12 ( 4 mm²) cable for AC end cable.

CAUTION

The installation technician is responsible for selecting a kind of AC cable and connecting the micro-inverter system to the home distribution network correctly.
The AC connecters may be provided by different suppliers. The port definitions are subject to actual objects.

Take out the AC connector from the package. Get the AC cable through the shell of AC connecter 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 3. Connect the DC cable

DANGER

When the photovoltaic array is exposed to light, it supplies 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 DC conductors of this photovoltaic system are ungrounded and may be energized.
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 DC extension cable, or get the DC connectors form TSUN.
Contact PV module manufacturers for the requirements of DC connectors in the module side of DC extension cable.

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

While using the TSOL-MS3000 microinverter, each DC input of the microinverter can connect two PV modules in series.

Step 4. Make an installation map

CAUTION

If there are more than one installation site, please make the installation map separately and give a clear description of the installation site.
The row of the table corresponds the shorter side of PV module and the column of the table corresponds the longer side of PV module. The direction on the upper left corner means the actual installation orientation.

Take out the SN labels and installation map from the package. Paste the SN labels on the installation map as below and complete the information of the solar plant.

Step 5. Start the System

DANGER

Only qualified personnel should connect this system to the utility grid.

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, turn on the main utility-grid AC circuit breaker. 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 as below.
