requirements; however, certain safety precautions must be observed when installing
and operating this inverter. Read and follow all instructions, cautions and warnings in
this installation manual. If questions arise, please contact Growatt’s technical services

2.4 Assembly Warnings
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.
Grounding the PV modules：The MIN 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 MIN TL-X.
Only ground the mounting frame of the PV modules.If you
connect grounded PV modules to the MIN 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.
