Read This First
Dear customer, thank you for choosing the TITAN series 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 TSOL-MS800/MS700/MS600/MS400/MS350
/MS300 microinverters 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 microinverter under the guide of this
document.
Important Safety Information
During installation, testing and inspection, adherence to all the handling and safety instructions
is mandatory. Failure to do so may result in injury or loss of life and damage to the equipment.

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

Use Nylon cable ties to fix the AC cables onto the frame.
Use a Connector Protective Cap to make sure the unused AC connector to be closed.
Step 3. Connect the AC end cable of each cable section
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 into 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. Separate the AC connector as shown below.

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:
If the microinverter is connected to 120/240V split-phase power grid, connect two live lines to port L
and port N.
If the microinverter is connected to 230/400V three-phase WYE power grid, connect the live line to
port L and connect the neutral line to port N, as the connection of single-phase power grid.
L: Live (Brown/Red)
N: Neutral (Blue/Black)

Step 4. 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 vol
tage 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 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.
