2 . How your Conergy Solar Power System Works
Solar energy is renewable and is different from conventional power generation in that:
| You are using environment friendly energy which doesn’t need big, pollution emitting power stations.
| It can also be generated on a small scale like on your rooftop.
| Once the solar power system is installed it costs you nothing to generate electricity.
Solar electricity generation works by converting energy from the sun, in the form of light, into electricity. Please note
that only light and not heat is transformed into electrical energy. Heat from the sun will have an adverse effect on
power generation as it slightly reduces the efficiency of solar cells.
Solar cells are made of semiconductors and work via what is known as the photovoltaic (PV) effect. In this process
when light hits a conductor and semiconductor it transfers its energy to that conductor. Light is actually a stream of
energy particles called photons. When the photons hit the silicon surface in the solar cells they generate electricity by
transferring energy and freeing electrons. In this way electricity is generated. Put simply, photovoltaic cells are energy
converters - converting the energy from sunlight into electricity.
Solar modules usually contain multiple number of solar cells encased in a durable casing. Toughened glass is used
to cover and protect the solar cells and a antireflective coating is used to minimise light reflection from the surface.
Solar modules produce DC power, usually at 12V or 24V. The inverter included in your Conergy SunEasy solar power
system converts DC power to AC power and feeds it into the electricity grid, if not used in your household directly.
With this setup, if you are using less power than you are producing, your meter runs backwards. If you are using
more power than you are generating your meter runs forwards. Some utilities require that you install two independent
energy meters. One to measure your consumed energy and the other for metering the amount of electricity your
system has returned to the grid. Your energy retailer will credit/charge you the difference between your consumed
energy and your generated energy.

2.3 Safety
The following safety instructions are important for your personal safety and for the optimum performance of your
solar power system. Please take the time to go through the following checklist with your installation team. The
safety instructions must NOT be ignored.
| The service and maintenance of your newly installed solar power system must be carried out by a licensed
electrical contractor in strict compliance with the Australian building and electrical safety rules.
| If you are not a licensed electrical contractor or a qualified person do not attempt to do any modification and/or
maintenance work on the solar power system. Doing so may put you in danger and may also void component
warranties.
| Never pour cold water on solar module surfaces when the sun is shining and they are hot. Doing so can shatter
the solar module glass. This type of damage will not be covered by the solar module warranty. This activity could
also expose you to the danger of electrocution.
| Never walk on the surface of the solar modules. Doing so will damage the solar module and will not be covered by
warranty.
| Avoid working in the vicinity of the installed solar module area when raining or when the area is still wet.
| The installed solar power system generates electricity when exposed to the sun. The generated voltage is
dangerous and can be fatal. The whole surface must be covered by black sheets prior to working on the system,
in order to ensure that no electricity is being generated.
| Observe all safety signs installed as part of your system.
| Please note that DC voltages will be present on the solar module side of the inverter even if the isolating circuit
breakers are completely switched off.
Your solar system is an electric power generation system and, as a result,
contains current-carrying components. Contact with electric current can be FATAL!
Never ignore safety hazards
Opening system components
Beware of the risk of death from touching electrical components! Do not open any of the components of your solar
power system unless you are a qualified licensed electrical contractor.
Repairs or modifications
Any work on the electrical components, such as repairs or modifications, must be carried out by a licensed
electrical contractor.
Guarantee and warranty claims
The guarantee and warranty claims will be void if unauthorised persons open or modify components.
Electrical work
The solar power system must be shut down before commencing any electrical work on the building.

Operational safety
Please observe all safety signs installed and all warnings laid out in the accompanying operating instructions.
Shut-down procedure
The following procedure must be followed to shut down the system, Please refer to the system drawings on page
13):
1. Disconnect the utility grid system to the inverter via AC Grid Disconnection Circuit Breaker labelled Q1.
2. Disconnect the DC power to the inverter at the DC side of the inverter via Grid Disconnection Circuit
Breaker – labelled Q2.
3. Disconnect the DC power to the Building DC cable on the roof via the Roof Isolating Circuit Breaker (if
applicable) – labelled Q3.
4. Disconnect all MC plugs between all solar modules to create lower voltage for a safe work environment.
DC voltage when system is shut down
Even if the system has been disconnected from the grid via a circuit-breaker, voltage is still present in the solar
panels during daylight hours.
In case of fire try and and shut down the system as far as possible. All circuit breakers must remain off until the fire
is extinguished.
Do not touch electric components such as wires, connection terminals, generator
junction boxes or plug connectors – there is a risk of electric shock or even death.
Daylight voltage in the solar modules
In daylight hours, as well as at dusk and dawn, DC voltage will be present in the connected wires and cables.
Safe work on roofs
After shutting down your system in the order above, if persons are working on your roof, you must make them
aware that there is the possibility of a small, non-lethal electrical charge being present in the base frame and
module frames.
Cleaning the solar array
Depending on the roof slope, the solar panels clean themselves during rainy weather. However, a layer of dust can
form if there is a prolonged dry spell. This could reduce the amount of energy produced by the solar power system.
Your system output has been calculated to take account of this dust. We do NOT recommend that you climb on
the roof to clean the solar panels. Please do not use ANY high-pressure cleaner or chemical cleaning product on
the surface of the solar panels – use plain water at mains pressure or less. All electric components, such as cables,
connectors, generator junction boxes etc. must remain dry.
CAUTION: Never wash the solar panels while they are hot! Cold water on hot solar panels may cause the glass to
shatter. Note that solar panels may be hot even when it is cloudy; and that the temperature of the solar panel can
be up to 20°C higher than the site ambient temperature.
Do not open the inverter!
Never open the inverter housing, even when switched off. The inverter should only
be opened by a licensed electrician.

Warning notices
Safety Signs and Instructions
All safety instructions and warning signs installed with the system:
• Must be kept in a legible condition
• Must not be damaged
• Must not be removed
• Must not be covered, pasted or painted over
DC disconnecting device
DO NOT disconnect the inverter’s DC side when the inverter is
switched on or when solar panels are producing energy.
DC plugs must never be disconnected from the sockets of the solar modules as long as the Conergy WR unit is
feeding power into the mains. Before disconnecting the DC plug you must always disconnect AC power to the
inverter.
To carry out maintenance work, your installer needs to switch the system off via the AC circuit breaker Q1 and then
disconnect the DC side, as per the shutdown procedure.
