Microinverter Installation

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 under-
neath 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 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 2. Fix the microinverter.

DANGER
·Do not install the equipment in adverse environment conditions such
as flammable, explosive, corrosive, extreme high or low temperature,
and humid.
WARNING
·Choose 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.
·The distance between every two micro-inverters should meet the
length of AC cables. The length of AC cables are shown as below:
Model
TSOL-MS800/MS700/MS600
TSOL-MS400/MS350/MS300
Choose an installation position. Using two pairs of screws and nuts
to fix the microinverter on the frame. Make sure that the label of
microinverter should be upside.

Step 3. Connect the AC cable of two microinverters

·According to the max current of the AC cables, there is a max
installation quantity for the micro-inverter in each cable section.
Every micro-inverter could be connected to the other one by its
AC cables.
Plug the female AC connector of one microinverter into a male AC
connector of another micro-inverter to form a continuous AC
branch circuit.
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.
