1.5 Glossary
AC
Abbreviation for "Alternating Current"
BAT
Abbreviation for battery.
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. Theyare
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.
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.

2.1 Intended Use

The unit converts the DC current generated by the battery (BAT) to grid- compliant
alternating current and performs single-phase feed-in into the electricity grid.MIN
2500TL-XA, MIN 3000TL-XA, MIN 3600TL-XA, MIN 4200TL-XA, MIN 4600TL-
XA, MIN 5000TL-XA, MIN 6000TL-XA 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 AC coupled inverter may only be operated with a permanent connection to the
public power grid. The AC coupled 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.

2.2 Qualification of skilled person

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