2 Safety Measures & Warning
4
Failure to observe a warning indicated in this manual may result in
injury.
Danger of high voltage & electric shock.
Don't touch, hot surface!
This side up. The package must always have the arrows point up.
No more than four identical packages stacked on each other.
Fragile.
Recyclable materials.
Special disposal instructions.
Keep Dry.
Refer to operation instructions.
Wait at least 5 minutes after disconnecting the inverter before
handling internal parts.
5min
CE mark.
• The GEP inverter strictly conforms and has been tested according to international safety
regulations.
• The manufacturer strongly advises installers to follow local safety regulations during
commissioning, operation and maintenance of the GEP inverter. Improper operation may result in
electric shocks or damage to equipment and property.
• The installation, maintenance and connection of the inverters must be performed by qualified
personnel, in compliance with local electrical standards, regulations and following the regulations
of the local power suppliers, companies and related authorities.
• If the GEP inverter is unpacked but not put into use immediately, please put it back to the original
package with the desiccant bag and seal it with tape.
• To avoid electric shocks, the DC input and AC output port of the inverters must be disconnected
for at least 5 minutes before performing any installation or maintenance.
• The temperature of some components of the inverters may exceed 60℃ during operation. To
avoid burns, do not touch the inverter during operation. Let the inverter cool before operating.
• Keep children away from the inverter.
• Touching or changing inverter components without following manual instructions may cause
personal injury, damage the inverters and could ultimately invalidate the warranty.
• The electronic components of the inverter could be damaged by static electricity. Appropriate
methods must be adopted to prevent such damage, otherwise the warranty may be null and void.
• Ensure the output voltage of the proposed PV array is lower than the maximum rated input voltage
of the inverter, otherwise the inverter may be damaged and the warranty may be null and void.
• When exposed to sunlight, the PV array generates dangerously high DC voltage. We strongly
advise operators strictly follow instructions and avoid actions that put lives at risk.
• The PV modules should have as a minimum an IEC61730 class A rating protection.
• If the equipment is used in a way not authorized by the manufacturer, the equipment built-in
protections may be damaged.
• In order to achieve complete equipment isolation: turn off the AC switch first, then turn off the DC
switch.
• Do not insert or pull the AC or DC terminals when the inverter is in operation.
• An Arc Fault Detector is recommended to be installed on the DC side of an earthing photovltaic
system.
• The inverter can exclude the possibility of DC residual currents to 6mA in the system, Where an
external RCD is required in addition to the built-in RCMU, type A RCD must be used to avoid
tripping.
• The PV is not grounded as default configuration.
01 02
To ensure IP65 protection is maintained, please make sure that the inverter is rigorously
packed and its components are sealed properly. GE strongly suggests to install the
inverter at most one day after it has been unpacked. If this is not the case and the
installation takes longer, please re-seal all the unused terminals and ensure that the
inverter and its components are not exposed to water or dust.
The manufacturer provides a standard warranty which comes with the inverter product and
prepaid warranty extension solution for our customer. For further details please visit:

3.2 Package
The unit is thoroughly tested and strictly inspected before delivery. Damage may still occur during
shipping.
1. Check the package for any visible damage upon receiving.
2. Check the inner contents for damage after unpacking.
3. Check the package list below.
4 Installation
4.1 Mounting Instructions
1. In order to achieve optimal performance, the ambient temperature should be lower than 45℃.
2. For easy maintenance, we suggest to install the inverter at eye level.
3. Inverters should not be installed near flammable and explosive items. Strong electro-magnetic
charges should be kept away from installation site.
4. Product label and warning symbols should be located and placed in a manner that can be easily
ready by users.
5. Ensure the inverter is installed in a location that is protected from direct sunlight, rain and snow.

4.2 Equipment Installation
4.2.1 Select installation location
Please take the following points into consideration when you selecting a proper location to install
inverter.
1. Please choose appropriate mounting methods and installation location taking both the weight
and dimension of inverter into account.
2. The location must be well ventilated and sheltered from direct sunlight.
3. Install the inverter vertically or with a backward tilt up to 15 degrees maximum. No lateral tilt is
allowed. The inverter should not be tilted sideways. The area of the connectors should point
downwards.
Maximum
15°

4. To guarantee the enough space for heat dissipation and facilitate the installation and removal,
the spacing around the inverter should meet the requirements as demonstrated in the following
illustration.

4.3 Electrical Connection
4.3.1 AC Side Connection
1. When connecting the inverter, please make sure to adjust the voltage and the frequency in
compliance with grid regulations and the specifications of the inverter installed.
2. Add a breaker or fuse to the AC side. Please note that the specification should be more than 1.25
times the rated AC output current.
3. The PE wire of the inverter should be connected to earth. Make sure the impedance of neutral
wire and earth wire is less than 10Ω.
4. Disconnect the breaker or fuse between the inverter and the utility.
5. When laying the AC Wire make sure that the protective earthing conductor is not strained.
500mm
4.2.2 Mounting procedure
1. Use the wall-mount bracket as a template and drill holes with 10mm in diameter and 80 mm in
depth on the wall.
2. Fix the wall-mount bracket on the wall with the expansion bolts in the accessories bag.
3. Hold the inverter by the side groove.
4. Mount the inverter onto the wall-mount bracket.
