1. Risk of ElEctRic shock:
Alternating Current (AC) and Direct Current (DC) sources are termi-
nated in this device. To prevent risk of electric shock during mainte-
nance or installation please ensure that all AC and DC terminals are
disconnected.
2. handling youR PV-inVERtER:
The PV-Inverter should only be handled by qualified service person-
nel. When the PV-panel is exposed to sunlight and connected to the
device, it generates a DC voltage charging the DC link capacitors.
After disconnecting the PV-Inverter from the power supply and PV-
panel, electrical charge can still reside in the DC link capacitors. The
device shall be touched by qualified personnel earliest 60 minutes
after disconnecting.
3. Public suPPly mains only:
The PV-Inverter is designed to feed AC power directly to the public
supply mains. Do not connect the AC-output of this device to any
private AC equipment.
4. bEwaRE of hot suRfacEs:
Although designed to meet international safety standards, the PV-
Inverter can become hot during operation. Do not touch the heat-
sink or peripheral surfaces during or shortly after operation.

3. OVERVIEW
3.1 intRoducing thE gRid-connEctEd PV systEm
The grid-connected PV System is mainly composed of 4 parts: the
PV-panels, the PV-Inverter, the AC-Connection Unit (the connection
Interface) and a connection to the Public Grid.
When a PV-panel is exposed to sunlight and connected to an inverter,
it generates DC power. The PV-Inverter converts DC to AC and feeds in
to the Public Grid via the AC-Connection unit.

SUGGESTIONS BEFORE MOUNTING
To obtain optimal results from your PV-Inverter, please consider the
following guidelines before installing the device:
Do not expose the PV-Inverter to direct sunlight. Direct sunlight increa-
ses the internal temperature that may reduce conversion efficiency.
- Check the ambient temperature of installation is within specified range
-20 ~ +55 °C.
- The AC grid voltage is between 196 and 253 VAC, 50/60 Hz.
- Electric utility company has approved the grid connection.
- Qualified personnel are performing the installation.
- Adequate convection space surrounds the inverter.
- Inverter is being installed away from explosive vapors.
- No flammable items are to be near the inverter.
Protect PV can be installed and operated at locations where the am-
bient temperature is up to 55 °C. However, for optimal operation, it is
recommended that Protect PV is installed where the ambient tempera-
ture is between 0 ~ 40 °C.

13
mounting PRotEct PV to thE wall
1. Choose a dry place, out of direct sunlight with ambient temperature
between 0 and 40 °C.
2. Select a wall or solid, vertical surface which is strong enough to sup-
port the inverter.
3. The PV-Inverter requires adequate cooling space for heat dispersal.
Reserve at least 20 cm above and below the inverter.
Minimum space 20 cm
Minimum space 20 cm

5.3 connEcting thE ac-outPut cablE
Connect your PV-Inverter to the AC-Connection unit via the AC-output
cable as following steps:
(1) Open the AC-output cover with
a screw driver.
(2) Draw out the AC Connector set
from the Inverter.

(3) Unscrew the cable lock and prepare
your AC cable.
(4) Remove the rubber plug from inside the
AC connector socket.
(5) Insert the provided rubber bushing
with three holes into the AC connector
socket.

19
(7) Fix the brown wire to L (Line); the blue
wire to N (Neutral); and the yellow-green
wire to G (Ground).
All three wires should be firmly connec-
ted.
(8) After checking the 3 wires are fixed pro-
perly, push the AC-output connection
set back in to the Connection Panel.
Drive the 4 screws back to fix the set.
(6) Now insert the three wires of the AC
cable into the bushing holes.
L for Line
N for Neutral
G for Ground

20
(9) Now screw the Connector
Locker in tight to fix the
bushing and cable.
(1) First make sure that the maximum open circuit voltage Voc of each
PV string is below 750VDC UNDER ANY CONDITION.
(2) Always connect PV-Panel positive (+) terminal to PV-Inverter DC
positive (+) terminal, and the PV-Panel negative (-) terminal to PV-
Inverter DC negative (-) terminal.
(3) Each set of PV-Inverter DC terminals takes a maximum DC input
of 8.5 A. As a result, 3 pairs of PV-Inverter DC terminals can take a
combined input of up to 25.5 A.
