2 Safety Measures & Warning

• 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.

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 into account the

weight and dimension of inverter.

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.

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.

4.2.2 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.

4.3 Electrical Connection

4.3.1 AC Side Connection

1. When connecting the inverter, please make sure both the voltage and the frequencey of the

inverter installed are complied with grid regulations and the inverter’s specification.

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. The AC connector brand compatible with the inverters is Exceedconn.

6. When laying the AC Wire make sure that the protective earthing conductor is not strained.

The Actual AC Connector is shown in the accessory box.
