Read This First

Dear customer, thank you for choosing the TITAN series micro inverter 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 micro inverter, or simply micro inverter, is a plug-and-play device used in photovoltaic, 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 micro inverter 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 micro inverter solution.
This manual contains important instructions for TSOL-MP3000/MP2250/MS3000 micro inverters and must be read in its 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 micro inverter under the guide of this document.

Microinverter Installation

Pre-installation Check

Check the Package

Although TSUN’s micro inverters have surpassed stringent testing and are checked before they leave the factory, it is uncertain that the micro inverters 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.
The package list is shown below:

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 inverters on structures underneath the photovoltaic modules so that they work in the shade without touching the rooftop.

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 the risk of electric shock.

WIFI Communication

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 directly sunshine.

CAUTION

·There are no screws and nuts in the package.

·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.

Tip: A space of 5cm needs to be left between the microinverter and the roof to ensure its heat dissipation.

Choose the best installation position. Use two pairs of screws and nuts to fix the micro inverter on the frame. Make sure that the label of the micro inverter should be the upside.

The micro inverter can also be mounted on the wall (vertically) using the optional support. In this case, first, fix the bracket to the wall with a pair of screws, and then fix the micro inverter to the bracket with one pair of nut screws.

Step 2. 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 micro inverter.

Step 3. 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 connectors 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 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 micro inverter and connect the AC cable to the AC distribution box.

Step 4. Connect the DC cable

DANGER

·When photovoltaic panels are 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 micro inverter.

CAUTION

·If the DC cable is too short for installation, use a DC Extension Cable to connect PV modules to the micro inverter.

·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 the DC extension cable.

Install the PV modules and connect the DC cable to the micro inverter.

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

Step 5. Make an installation map

CAUTION

·If there is 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 to the shorter side of the PV module and the column of the table corresponds to the longer side of the PV module. The direction in the upper left corner means the actual installation orientation.

CAUTION

·If there is more than one installation site, please make the installation map separately and give a clear description of the installation site.

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

Step 6. Start the System

DANGER

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

CAUTION

·Do not connect the micro-inverter (s) to the grid, nor energize the AC circuit(s) until you have completed all installation procedures and have received prior approval from the electricity 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 on startup. The LED definition is shown below:

Status	Indicates
Solid Green	Standby/Waiting/Checking Status
Flashing Green (1s)	Working normally
Flashing Red (1s)	Working abnormally
Solid Red	Fault
