General notes
The SUNLEAF is a transformerless solar inverter with two channels input of
MPPT, and it converts the DC current of PV generator to AC current and feed
it into the public grid.When you chose it, you have opted for reliable and
powerful technology.With protection class IP65, the units are ready for use in
all environmental conditions, and high efficiency meets your requirements.
GENERAL PRECAUTIONS
For your own safety and that of the unit, you must read and understand the
instructions contained in this document before starting to work.
Keep these instructions in a place accessible to all the personnel who work
with the unit so that these may be consulted.
Only professional technician may install and operate our units.
WARNING:
To avoid risk of electric shock from energy stored in capacitor, please
wait for at least 5 minutes to access the conductor part of input or output
terminals of the inverter after it is disconnected from the output of PV
panel and AC grid.
There is a fuse in our units. For continued protection against risk of fire,
replace only with same type and ratings of fuse. The replacement should be done
by qualified service personnel.
The installation of inverter must be performed in full compliance with the
National Wiring Rules of Standard AS/NZS 3000 and other relative local
standards and regulations.
No spare parts in package box. To avoid risk of electric shock, Do not remove
machine cover. No user serviceable parts inside. Refer servicing to qualified
service personnel. Please contact your reseller if you need to know the
nearest authorized repair center or qualified service personnel.
As a qualified service personnel, you should know both ac and dc voltage
sources are terminated inside this units. Each circuit must be individually
disconnected before servicing.
Read and understand all the instructions contained in this manual and become
familiar with the safety symbols in the relevant paragraphs before you install
and commission the equipment.
The connection to the AC grid must be done only after receiving approval from
the administering authority as required by national and state interconnection
regulations, and can be done only by qualified personnel.

Keep the whole surface of the photovoltaic panel covered with material
opaque to solar radiation before connecting panel to equipment; this will
ensure that no dangerous high voltage is present at the connection cables.
This unit is designed to feed power to the public power grid (utility) only. Do
not connect this unit to an AC source or generator. Connecting Inverter to
external devices could result in serious damage to your equipment. By the
way, we have special types for these applications. If you are interested, please
contact your local dealer.
Although designed to meet 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 solar inverter or nearby surfaces while
Inverter is operating. By the way, keep it away from any flammable objects.
This version
of
SUNLEAF inverters shall be used with
panels
connected in a
“floating” way, i.e. with positive and negative terminal not connected to the
ground.
The equipment is provided with several labels, some of them with a yellow
background, which are related to safety issues.
Make sure to read the labels and fully understand them before installing the
equipment.
The symbols are:
Equipment grounding conductor (Main grounding protective
earth, PE)
Alternate Current (AC) value
Direct Current (DC) value
Phase
Grounding (Earth)
To avoid risk of electric shock from energy stored in capacitor,
please wait for at least 5 minutes to access the conductor part
of input or output terminals of the inverter after it is
disconnected from the output of PV panel and AC grid.
Caution: The temperature of metal enclosure may be high
during operation.

2.1 Package Inspection
The customer is encouraged to perform the following checks:
Inspect the package box for apparent damage, such as holes, cracking or any
sign of possible damage to its contents.
Describe any damage or shortage on the receiving documents and have the
carrier sign his/her full name.
Open the package box and inspect the contents for internal damage. While
unpacking, be careful not to discard any equipment, parts or manuals. If any
damage is detected, call the delivering carrier to determine the appropriate
action. Save all shipping material for the event the carrier sends an inspector
to verify damage!
If the inspection reveals damage to the inverter, please call your local supplier
or the authorized distributor. They will determine if the equipment should be
returned for repair. They will also provide instructions on how to get the
equipment repaired;
It is the customer’s responsibility to file a claim with the carrier. Failure to file a
claim with the carrier may void all warranty service rights for any damage;
Carefully store the original packaging of SUNLEAF inverter since it shall be
used in case it is necessary to ship it for repair.
2.2 Se lecting th e place of installat ion
Place of installation should be selected based on the following considerations:
SUNLEAF inverters shall be set at a suitable height from the ground to enable
easy readout view of the display and the LEDs.
Select a well ventilated place sheltered from direct sun radiation. Choose a
place that allows fluent air flow around the unit.
Allow sufficient room around the unit to enable easy installation and removal of
the object from its mounting surface.
The following figure shows the recommended minimum clearances around the
inverter:
