The energy is the accumulation of power over time. for example, your inverter operates at a
constant power of 5000 W for half an hour and then at a constant power of 2500 W for
another half an hour, it has fed 3750Wh 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.

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 three-phase feed-in into the electricity Grid.
PH5000-T series 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.
Principle of a PV plant with this PH50-XXXXT three-phase inverter
Fig1.1
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 2.2uF.
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 100mA due to the
fact that the inverter would otherwise automatically disconnect from the electricity grid as a
protective measure.

installation and operation may result the serious safety and shock hazards 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.
Grounding the PV modules: The PH5000-T is a high frequency inverter(without
transformer). That is why it has no galvanic separation. Do not ground the DC
circuits of the PV modules when connected to the PH5000-T. Only ground the
mounting frame of the PV modules. If you connect grounded PV modules to the
PH5000-T, that will show error message "PV ISO Low".
Follow the local requirements for grounding the PV modules and the PV generator.
We recommend 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.
The components in the inverter are mobilizable. Touching mobilizable components
can result in serious injury or death.
Do not open the inverter except the wire box by qualified persons.
Electrical installation, repairs and conversions may only be carried out by
electrically qualified persons.
Do not touch damaged inverter.
Danger to life due to high voltages in the inverter.
There has residual voltage in the inverter. The inverter takes 20 minutes to
discharge.
Wait 20 minutes before you open the wire box.
Persons with limited physical or mental abilities may only work with the PH5000-T
inverter following proper instruction and under constant supervision. Children
are forbidden to play with the PH5000-T inverter. Must keep the PH5000-T inverter

Make all electrical connections (e.g. conductor termination, fuses, PE connection,
etc.) in accordance with prevailing regulations. When working with the inverter,
adhere to all prevailing safety regulations to minimize risk of accidents.
Systems with inverters typically require additional control (e.g., switches,
disconnects) or protective devices (e.g., fusing circuit breakers) depending
on the prevailing safety rules.
The PH5000-T Inverter converts DC Current from PV generator into AC current.
The inverter is suitable for mounting indoors and outdoors.
You can use the AC current generated as follows:
Energy flows into the house grid. The consumers connected,
for example, household devices or lighting, consume the energy.
The energy left over is fed into the public grid. When the
PH5000-T is not generating any energy, e.g., at night, the
consumers which are connected are supplied by the public
grid. The PH5000-T does not have its own energy meter. When
energy is fed into the public grid, the energy meter spins
backwards.
Energy is fed directly into the public grid. The PH5000-T is
connected to a separate energy meter. The energy produced is
compensated at a rate from the electric power company.
Make sure all covers and doors closed and secure during operation.
Although designed meeting all safety requirements, some parts and surfaces
of Inverter are still hot during operation. To reduce the risk of injury, do not
touch the heat sink at the back of the PV-Inverter or nearby surfaces while
Inverter is operating.
Incorrect sizing of the PV plant may result in voltages which could destroy
the inverter.
Switch the rotary DC Disconnect to the Off position immediately.
Contact installer.
All operations regarding transport, installation and start-up, including
maintenance must be operated by qualified, trained personnel and in
compliance with all prevailing codes and regulations.
Anytime the inverter has been disconnected from the power network, please
be much careful as some components can retain charge sufficient to create a
shock hazard; to minimize occurrence of such conditions, please comply with
all corresponding safety symbols and precautions and present on the unit and
in this manual.
In particular 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 location or 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 20 cm to the inverter for any length of time.
