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
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.

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

10

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

6.3 Connecting the second protective conductor

In some installation countries, a second protective conductor is required to prevent a touch current
in the event of a malfunction in the original protective conductor.For installation countries falling
within the scope of validity of the IEC standard 62109, you must install the protective conductor
on the AC terminal with a conductor cross-section of at least 10 mm²Cu.Or Install a second
protective conductor on the earth terminal with the same cross-section as the original
protective conductor on the AC terminal. This prevents touch current if the original protective
conductor fails.
