2 Safety And Conformity
2.1 Safety Instructions
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.
Grounding The PV Generator
Comply with 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.
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 470nF. 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 30mA due to the fact that the inverter would
otherwise automatically disconnect from the electricity grid as a protective
measure.
DC and AC Breaker
Disconnecting the unit securely from the grid and the PV generators, battery using DC and
AC breaker. DC and AC breaker shall be able to disconnect all non- ground conductors after
installation.
Grounding The PV Modules
This unit is a transformer-less inverter. It has no galvanic separation. Do not earth the DC
circuits of the PV modules to the inverter. Only Earth the mounting frame. If you bond the
PV modules to the inverter you will receive an error message "PV ISO Low".

Figure 2
3.2 Information of the Unit
The unit is bidirectional which applies to the PV system with battery storage. Energy produced
by the PV system is used to optimize self-consumption. Excess energy is used to charge the
batteries, and then fed into the public grid when the PV energy is adequate.
When PV energy output is insufficient to support connected loads, the system automatically
draws energy from the batteries if battery capacity is sufficient. If the battery capacity is
insufficient to meet own consumption requirements, electricity will be drawn from the public
grid.

Figure 3
All electrical installations shall be done in accordance with the IEE Wiring Regulations.
Do not remove the casing. The inverter contains no user serviceable parts. Please refer
servicing to qualified service personnel.
All wiring and electrical installation should only be conducted by a qualified electrician.
Carefull y remove the unit from its packaging and inspect for external damage. If you find
any imperfections, please contact your local supplier.
The inverter must only be operated with PV generation. Do not connect any other source
of renewable energy to it.
Both AC and DC voltage sources are terminated inside the PV Inverter.
Please disconnect these circuits before servicing.
This unit is designed to feed power to the public power grid (utility) only. Do not connect
this unit to a generator. Connecting the inverter to external devices could result in
serious damage to your equipment.
When a photo-voltaic panel is exposed to light, it generates a DC voltage. When
connected to this equipment, a photo-voltaic panel will charge the DC capacitors.
Energy stored in this equipment's DC capacitors presents a risk of electric shock. Even after the
unit is disconnected from the grid and photo-voltaic panels, high voltages may still exist inside
the PV-Inverter.
Although designed to meet all safety requirements, some parts and surfaces of the
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.
