1.5 Glossary
AC
Abbreviation for "Alternating Current"
DC
Abbreviation for "Direct Current"
Energy
Energy is measured in Wh (watt hours), kWh (kilowatt hours) or MWh (megawatt
hours). The energy is the power calculated over time. For example, your inverter
operates at a constant power of 4600 W for half an hour and then at a constant power
of 2300 W for another half an hour, it has fed 3450Wh of energy into the power
distribution grid within that hour.
Power
Power is measured in W (watts), kW (kilowatts) or MW (megawatts). Power is an
instantaneous value. It displays the power your inverter is currently feeding into the
power distribution grid.
Power rate
Power rate is the radio of current power feeding into the power distribution grid and

9
the maximum power of the inverter that can feed into the power distribution grid.
Power Factor
Power factor is the ratio of true power or watts to apparent power or volt amps. They
are identical only when current and voltage are in phase than the power factor is 1.0.
The power in an ac circuit is very seldom equal to the direct product of the volts and
amperes. In order to find the power of a single phase ac circuit the product of volts
and amperes must be multiplied by the power factor.
PV
Abbreviation for photovoltaic
wireless communication
The external wireless communication technology is a radio technology that allows the
inverter and other communication products to communicate with each other. The
external wireless communication does not require line of sight between the devices
and it is selective purchasing.
2 Safety
2.1 Intended Use
The unit converts the DC current generated by the photovoltaic (PV) modules to
grid-compliant alternating current and performs single-phase feed-in into the
electricity grid.MIN 7000-10000TL-X inverters are built according to all required
safety rules. Nevertheless, improper use may cause lethal hazards for the operator or
third parties, or may result in damage to the units and other property.

Utility grid
The inverter may only be operated with a permanent connection to the public power
grid. The inverter is not intended for mobile use. Any other or additional use is not
considered the intended use. The manufacturer/supplier is not liable for damage
caused by such unintended use. Damage caused by such unintended use is at the sole
risk of the operator.
PV modules Capacitive Discharge Currents
PV modules with large capacities relative to earth, such as thin-film PV modules with
cells on a metallic substrate, may only be used if their coupling capacity does not
exceed 1uF. During feed-in operation, a leakage current flows from the cells to earth,
the size of which depends on the manner in which the PV modules are installed (e.g.
foil on metal roof) and on the weather (rain, snow). This "normal" leakage current
may not exceed 50mA due to the fact that the inverter would otherwise automatically
disconnect from the electricity grid as a protective measure.
2.2 Qualification of skilled person
This grid-tied inverter system operates only when properly connected to the AC
distribution network. Before connecting the MIN TL-X to the power distribution grid,
contact the local power distribution grid company. This connection must be made only
by qualified technical personnel to connect, and only after receiving appropriate
approvals, as required by the local authority having jurisdiction.
2.3 Safety instruction

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.
CAUTION
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.
