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 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.

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
2500TL-XH, MIN 3000TL-XH, MIN 3600TL-XH, MIN 4200TL-XH, MIN 4600TL-
XH, MIN 5000TL-XH, MIN 6000TL-XH 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.

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 inverter system operates only when properly connected to the AC distribution network.
Before connecting the MIN TL-XH 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.
