4. FEATURES OF SUNSYS-B10
This Inverter mainly has following features:
Lead-free, RoHS GP2 compliant
Max conversion efficiency ≧97.7%
Euro efficiency ≧97%
IP65 enclosure
128x64 graphic display
3-phase 4 wire, 230/400V

4.1.Maximum Power Point Tracking (MPPT)
A PV inverter must be able to convert the maximum power from any PV panel. Due to its advanced design, this
PV inverter can track the maximum power from the PV panel in any condition. When the displayed power on
the LCD output does not change dramatically, the Inverter is converting the maximum power from panels.
When the LCD power reading is significantly changes, the Inverter is tracking the power according to the varied
sunlight.

When the PV panel’s output is low, the feeding DC-power may drift slowly as does the AC power. It is
because PV inverter is tracking maximum DC-power constantly.

5.INTALLATION INSTRUCTION
5.1.Inside the Package
After opening the package, please check the contents of the box.
It contains the following items:
1. N°1 Photovoltaic Inverter;
2. N°1 User’s Manual;
3. N°6 Screw (M4 x 30L) with relative Nylon Drive Anchor;
4. N°2 Security Screw;
5. N°1 Mounting Bracket;
6. N°1 AC Cover;
7. N°2 Rubber Bushing.
5.2.Mounting SUNSYS –B10 PV inverter
Advice before Installation
To obtain optimal performance, please consider following guidelines before installation:
Do not expose the PV inverter to direct sunlight. Direct sunlight increases the internal
temperature that may reduce conversion efficiency.
Check the ambient temperature of installation is within specified range -20 ~ +60 C.
The grid voltage and frequency at installed site must be within the specific range defined by applicable
regulation type.
Electric utility company has approved the grid connection.
Only qualified personnel are performing the installation and maintenance.
Adequate convection space surrounds the Inverter.
Inverter is being installed away from explosive vapor or dust.
No flammable object is near the Inverter.
No mounting on wooden flammable surface.
SUNSYS –B10 grid-tied PV inverter can be installed and operated at locations where the
ambient temperature is up to 60 C. However, for optimal operation, it is recommended that
Inverter is installed where the ambient temperature is between 0 to 40 C.

13
Please be sure the installation rules listed below are followed.
1. Select a wall or solid vertical surface that can support the PV inverter in the long run.
2. PV inverter requires adequate cooling space. Allow at least 30cm space above and 90cm space below
the Inverter.
3. For maintenance purpose, please keep Inverter 30cm distance at least from each other.
Note: Don’t mount PV inverter on top of another one or other heat radiating sources unless it is inevitable, in
that case, 100cm spacing at minimum from each other is required to provide proper ventilation effect.
A. Fix the Bracket by using all of six mounting holes, the bracket should be fixed with M5*30mm screws
by 30kgf-cm (or 2.94 N-m ) torque force, as illustrated below:
*Notes: Diameter for the safety screw is at 10mm.
B. PV inverter will be able to lift up with the proper lifting tool in order to move PV inverter to the installed

14
location when the hanging irons installed on the PV inverter as illustrated:
*Notes: Proper lifting tool must be used for the lifting, please beware.
C. Mount the Inverter onto the bracket as illustrated:

15
D. Check and ensure the device is properly fixed to the bracket in the proper direction.

16
5.3.Connecting AC Output Cable
Connect PV inverter to the AC Junction Unit with AC output wires and ground wire as shown in the following
steps:
1. Do not use cables where losses will exceed 1%
L1(phase1), L2(phase 2), L3(phase3), N(neutron), PE(hearth ground): wires gauge 4/6 mm2
PE(hearth ground): wires gauge 10mm2
2. Remove the rubber plug from inside of the AC connector socket
3. Insert all AC wires through AC cover kit in following order before cramped with insulated
cord end terminal: cable gland rubber bushing AC cover cord end terminal
4. Connect the AC wires to the AC terminal block correspondingly and tighten it properly.
PE2 wire area must be of same gauge as PE1 does (or 10 mm2).
5. Add an insulated cord end terminal to each AC wire before connecting. The stripped length of AC wire is
about 10 mm to 12 mm.

17
6. Fix the AC output cover back with a screwdriver.
7. Twist the connector cable gland to lock the bushing and cable together firmly.
8. Check the installation condition again.
Do not install the PV inverter on a slanted surface
Check Inverter are securely hooked on bracket at both of upper and lower sides.

18
5.4.Connecting of the PV Modules
For connecting DC input of one single Inverter, connected strings must consist of modules of the same type.
Do not share the DC input connection with other Inverter. The number, orientation, and tilt of panels may differ
for different application.
The input terminals on the Inverter are Multicontact MC4 DC connectors. Appropriate cable couplers from the
same manufacturer should be used for DC input connection.
The following table lists those connector pairs:
Advice before connecting of PV module
To obtain optimal result from PV inverter, please consider the following guidelines before connecting the PV
modules to the device:
1. Firstly make sure the maximum open circuit voltage (Voc) of each PV string does not exceed the related
specification as below table listed in all condition.
2. Check short-circuited current of the PV string. The total short-circuits current (Isc) of the PV string should
not exceed the Inverter’s maximum DC current.
3. Always connect PV modules positive (+) terminal to PV inverter DC positive (+) terminal; negative (-)
terminal to PV inverter DC negative (-) terminal.
4. Each group of terminals of the DC 'inverter converts a DC current of maximum 24A.

19
How to Disconnect MC4 DC connectors
The following pictures illustrates how to disconnect MC4DC connector by using a connector extractor as
below figure shown, the connector extractor shall be found in accessories box shipped along with package of
Inverter.
1. Insert the tool through the connector in either way to cramp its clips. As below figure shown:
2. After cramping the clips, pull the connector slightly downward to disassemble the DC cable.

5.5.Switch grid connection
The AC power switch is an interface between the PV inverter and the public network.
The value of this switch (recommended 32 A,400V, 4 poles), must be designed by a qualified technician in
order to meet the local safety regulations.
Is also recommended the use of a differential switch type A / AC value of> 300mA.
