Prior to installation, inspect the unit to ensure absence of any
transport or handling damage, which could affect insulation
integrity or safety clearances; failure to do so could result in
safety hazards.
Assemble the inverter per the instructions in this manual. Use care
when choosing installation location and adhere to specified
cooling requirements.
Unauthorized removal of necessary protections, improper use,
incorrect installation and operation may lead to serious safety
and shock hazards and/or equipment damage.
In order to minimize the potential of a shock hazard due to
hazardous voltages, cover the entire solar array with dark
material prior to connecting the array to any equipment.
Ø
Grounding the PV modules
：
The MIC TL-X is a transformerless
inverter. That is why it has no galvanic separation. Do not ground
the DC circuits of the PV modules connected to the MIC TL-X.
Only ground the mounting frame of the PV modules.If you
connect grounded PV modules to the MIC TL-X, the error
message "PV ISO Low".
Comply with the local requirements for grounding the PV
modules and the PV generator. GROWATT recommends
connecting the generator frame and other electrically conductive
surfaces in a manner which ensures continuous conduction with
ground in order to have optimal protection of the system and
personnel.

WARNING
CAUTION
CAUTION
Do not open the inverter except the wire box by qualified persons.
Electrical installation, repairs and conversions may only be carried
out by electrically qualified persons.
Do not touch damaged inverters.
Ø
Danger to life due to high voltages in the inverter
Ø
Persons with limited physical or mental abilities may only work
with the Growatt inverter following proper instruction and under
constant supervision. Children are forbidden to play with the
Growatt inverter. Must keep the Growatt inverter away from
children.
There is residual voltage in the inverter. The inverter takes 20
minutes discharge.
Ø
The components in the inverter are live. Touching live components
can result in serious injury or death.

Ensure all connectors are sealed and secure during operation.
Although designed to meet all safety requirements, some parts
and surfaces of Inverter are still hot during operation. To reduce
the risk of injury, do not touch the heat sink at the back of the PV-
Inverter or nearby surfaces while Inverter is operating.
Incorrect sizing of the PV plant may result in voltages being
present which could destroy the inverter. The inverter display will
read the error message “PV voltage High!”
Turn the rotary switch of the DC Disconnect to the Off position
immediately.
Contact installer.

All operations regarding transport, installation and start-up,
including maintenance must be operated by qualified, trained
personnel and in compliance with all prevailing codes and
regulations.
Anytime the inverter has been disconnected from the power
network, use extreme caution as some components can retain
charge sufficient to create a shock hazard; to minimize
occurrence of such conditions, comply with all corresponding
safety symbols and markings present on the unit and in this
manual.
In special cases, there may still be interference for the specified
application area despite maintaining standardized emission limit
values (e.g. when sensitive equipment is located at the setup
location or when the setup location is near radio or television
receivers).In this case, the operator is obliged to take proper
action to rectify the situation.
Do not stay closer than 20 cm to the inverter for any length of
time.

Make all electrical connections (e.g. conductor termination,
fuses, PE connection, etc.) in accordance with prevailing
regulations. When working with the inverter powered on, adhere
to all prevailing safety regulations to minimize risk of accidents.
Systems with inverters typically require additional control (e.g.,
switches, disconnects) or protective devices (e.g., fusing circuit
breakers) depending upon the prevailing safety rules.
