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 ARO-US 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 ARO-US 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 then 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
ARO-US 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 Safety 2

Danger to life due to lethal voltages!
Lethal voltages are present within the unit and on the power supply lines.
Therefore, only authorized electricians may install and open the unit. Even
when the unit is disconnected, high contact voltages may still be present
within the unit.
Danger of burn injuries due to hot enclosure parts!
During operation, the four sides of the enclosure lid and the heat sink may
become hot. Only touch the front enclosure lid during operation.
Electric arc hazards!
he product has large electrical potential differences between Its conductors.
Arc flashes can occur through air when high-voltage current flows. Do not
work on the product during operation.
Risk of fire!
Improper installation of the product may cause a fire.
Possible damage to health as a result of the effects of radiation!
In special cases, there may still be interference for the specified application
area despite maintaining standardized emission limit values (e.g. when
sensitive equipment is located at the setup locationor when the setup
location is near radio or television receivers).In this case, the operator is
obliged to take proper action to rectify the Situation. Do not stay closer than
8inch to the ARO-US for any length of time.
Grounding the PV generator!
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 these in order to have optimal protection of the
system and personnel.
Permanent connection!
The ARO-US may only be operated with a permanent connection to the
public power grid. The ARO-US 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 suchunintended 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 ARO-US would otherwise automatically disconnect
from the electricity grid as a protective measure.
