System introduction
The system is a single stage parallel circuit photovoltaic inverter. As opposed to traditional
photovoltaic inverters, no expensive and bulky batteries are required. Hence, eliminating
large expenses on battery maintenance. It can convert photovoltaic DC energy via solar
panel modules and inverts collected energy into alternate current, which is then fed directly
into the power grid. Such design can benefit from both direct power generating and energy
conservation. The control panel adopts Digital Signal Processor (DSP), with the most
advanced digital control technology, to increase power conversion efficiency and
supplementary functions. Output stage circuit is of single stage with high frequency
switchable IGBT. The circuit design has the advantage of being both simple and high
efficiency. PV inverter system can be monitored remotely via software. It provides users with
convenient power monitoring and recording functions without the need of additional
monitoring systems.

2. Installation
Warning : All electrical installation shall be done in accordance
with local and national codes ANSI/NFPA 70.
Warning : Connecting the Soleil 2000 to the electrical grid shall
only be performed by qualified personnel and only after formal
approval from the utility company.
Caution : For proper circuit isolation, use 2.0KW rated isolating
transformer model SYST1201 supplied by Samlex Solar between
the output of the unit and the utility power line connection.
Placement of Soleil 2000
Soleil 2000 can be installed indoor
where sufficient air circulation is available with ambient
temperature less then 50℃.
Outdoor installation should be under controlled environment where no direct sunlight
would reach, as excessive heating would damage internal components and should minimize
exposure to rain despite her high protection class IP 65 ( NEMA 3R).
The unit should be installed in a location normally inaccessible to persons.
Avoid mounting on wall of resonant materials like wooden
or plastic panels as Soleil 2000
may slightly vibrate when working under load.
Please install this unit at eye-height (over 1 meter),
so that all information and status from
LCD display can be read easily. Also please provide sufficient space on both sid
es of the unit
so that Cautions and Ratings would be easily visible.
Mount only on firm background and with correct position as below :
Fig. 2-1 mount straight or tilted to the back nevermount tilted to front
Outdoor Installation shall not proceed on rainy day. High humidity within the unit may

www.samlexamerica.com Toll free 1-800-561-5885

eventually damage the electronics that are sensitive to humidity.
Ambient temperature should be between –20°C and +50°C.
Heat sink may reach over 70 oC, so pay special attention to air circulation for sufficient
heat dissipation. For indoor unit, please provide external ventilation.
Mounting of Soleil 2000
Place the mounting plate of Soleil 2000 with the slots on two sides bending inwards
against the designated surface of the wall and mark the holes of the screw.
Drill the holes and hammer in the wall anchors. If you are mounting the unit on wooden
wall, be sure that the wall is thick enough for penetration of the screws 1and1/2 “ depth
into it.
Place the mounting plate against the wall again with the slots bending outwards and
fasten the four screws into their respective holes until the mounting plate is firmly held
against the wall.
Fig. 2-2 Mounting plate
Mount the unit on the mounting plate. Be sure that the six hooks
from the side brackets of
the unit get into their respective fixtures on the slots of the plate and settle down.
To secure the unit, fasten a screw on the hole at the left bottom hook of the unit, as in
Fig 2-3.

3. Wiring process
The photovoltaic inverter wiring is as shown above.
Warning :National Electrical Code (NEC) requires that the inverter
be
connected to a dedicated circuit and no other outlets or device may be
connected to this circuit. See NEC Section 690-64(b)
Warning : Follow local electrical codes and the National Electrical
Code (NEC), ANSI/NFPA 70. Use copper conductors only with
minimum 12 AWG, 105℃, 600V wire for all connections with the
Soleil 2000.
Power cable selection
AC wire: Black copper wires of 12 AWG or above should be used for alternate current
output.
Ground wire: For enclosure grounding, green or yellowish green copper wires of
12AWG or above should be used.
DC wire: For input to the unit
from solar panels, the cross section area is dependent on the
length of the wire. Identifiable colored copper wires of 12 AWG or above, for both positive
and negative power supplies should be used.

www.samlexamerica.com Toll free 1-800-561-5885
11
Caution : Longer wire or Voltage drop would require that larger wire
sizes be used.
For a 70 feet (16.4 m) cable, use size of AWG 12
For a 100 feet (33 m) cable, use size of AWG 10
Notes for wiring
Make sure the unit is fixed securely and all power switchboards are switched to off
position to avoid electric shock.
This unit provides a terminal block for connections at DC Input terminal and is to connec
t
through DC knockout to PV string from the DC disconnect (schottky diode + circuit
breaker).
For AC output, connection should be made from the AC output terminal block
through AC
knockout to the Isolation Transformer and there after to AC disconnect and main b
reaker.
Excess power would be fed to the grid via a dual rate flow meter.
The AC equipment-ground wire should be connected from the ground terminal on the AC
output terminal block and together with AC Line & Neutral, go through AC knockout
to the
Isolation Transformer and there after to the Ground terminal of the AC disconnect and
main breaker ( power distribution unit ).
Warning : To reduce the risk of fire, do not connect to an AC load
center (circuit breaker panel) having multi-wire branch circuits
connected.

Connect the cable to the appropriate port of the communication PWB in the unit.
Connect the other end of the cable to the appropriate port of the PC.
Make sure the conduit fitting or cable grand on the knockout is sealed and safe from rain
Replacing the cover
After AC, DC and Communication wires are all connected, make sure the Isolation sheet
with cautionary markings covers over the power circuitry below and no pressure will be
exerted on any connections when the cover is fixed.
Position the cover on the Soleil 2000 carefully and align the four holes on the cover to the
threaded holes of the brass threaded spacers on the enclosure.
Carefully insert the four screws previously removed to take the cover off through the
nylon washers and the aligned holes and fasten them till they are finger-tight.
After verifying that the front cover is in correct position and the seal well in place, fasten
all screws till firmly tight.
Warning : Never install the Soleil 2000 during rainy day. Moisture
trapped inside the enclosure during those very damp conditions would
damage the sensitive electronic components.

4. Operation
Warning : Connection between the Soleil 2000, the PV string and the
utility grid must be done in the order described bellow. Operation
ignoring the order will cause hazardous accident.
Start operation
Verify all breakers are at OFF position.
Use an electricians’ multi-meter to test and make sure that the input voltage at DC
disconnect is within the correct range (200-450VDC).
Check both the voltage and frequency of main power grid is within the normal range.
Connect the Soleil 2000 to the utility by switching on AC Main breaker and AC
disconnect breaker.
Connect the Soleil 2000 to PV strings by switching on DC disconnect breaker.
After switching on the system, the Soleil 2000 will start boot up sequence. It will take a
few minutes to complete the self-
test cycle, as well as confirmation of power grid voltage
and frequency.
After confirming the AC voltage is within the correct working range, sunbeams can start
generating electrical power for user’s household electrical appliance and excess power
will be fed to utility grid automatically.
