GOODWE XS Series Single Phase 2 MPPT Small Residential Solar Inverter

INSTRUCTION

Safety Measures & Warning

The XS-Series strictly conforms and has been tested according to international safety regulations. GOODWE strongly advises installers to follow the local safety regulations during the commissioning, operation and maintenance of the XS-Series inverter. An 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.
To avoid electric shocks, the DC input and AC output port of the inverters must be disconnected and wait 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 being burnt, do not touch the inverter during operation. Let it cool before touching it.
Keep children away from the inverter.
Touching or changing inverter components without following the GOODWE’s manual instructions may cause personal injury, damage the inverters and ultimately be a reason for warranty invalidation.
The electronic components of the inverter may be damaged by static electricity. Appropriate methods must be adopted to prevent such damage, otherwise the GOODWE’s warranty may be void.
Make sure that 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 void.
When exposed to sunlight, the PV array generate dangerous high DC voltage; we strongly operators to strictly follow the GOODWE’s 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 GOODWE, the equipment built-in protections may be damaged.
In order to achieve a complete isolation of the equipment: Turn off the DC switch, disconnect the DC terminal, the AC terminal and the AC breaker
Do not insert or pull the AC or DC terminals when the inverter is in operation.
An earthing photovoltaic system requires the installation of an Arc Fault Detector on the DC side.
The below bullet points are not understandable. Urgently review!
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.

Please choose appropriate mounting methods and installation location in terms of weight and dimension of inverter.
The location must be well ventilated and sheltered from direct sunlight.
Install inverter vertically or with a backward tilt within 15 degrees. No lateral tilt is allowed.

Mounting procedure

Use the wall-mount bracket as a template and drill holes with 10mm in diameter and 80 mm in depth on the wall.
Fix the wall-mount bracket on the wall with the expansion bolts in the accessories bag.
Hold the inverter by the side groove.
Mount the inverter onto the wall-mount bracket

Electrical Connection

Connection To The Grid (AC Side Connection)

When connecting the inverter make sure to adjust the voltage and the frequency in compliance with the grid regulations and the specifications of the GOODWE.
Add a breaker or fuse to the AC side. Please note that the specification should be more than 1.25 times of rated AC output current.
The PE line of the inverter should be connected to earth. Make sure the impedance of neutral wire and earth wire is less than 10ohm.
Disconnect the breaker or fuse between the inverter and the utility.
Please note that there are two AC connector brands compatible with the inverters: VACONN and Exceedconn. Choose one of the to connect the inverter to the grid.
When laying the AC line make sure that the protective earthing conductor is not strained. Inverters are compatible with two brands of AC connector: VACONN and Exceedconn

AC CABLE SPECIFICATION

AC circuit breaker and leakage current protection device
Please install an independent two pole circuit breaker to protect the inverter and make sure it is safe to disconnect it from the grid. In addition to the built-in RCMU, an external RCD is required to ensure that the inverter system does not carry DC residual currents. To avoid tripping, the types A can be used.

Inverter Model	Recommended Circuit Breaker Speciﬁcations
GW700-XS/GW1000-XS/GW1500-XS	16A
GW2000-XS/GW2500-XS/GW3000-XS GW2500N-XS/GW3000N-XS /GW3300-XS/GW3KB-XS	25A

DC Side Connection

Before connecting the PV strings, please ensure the plug connectors have the correct polarity.
Incorrect polarity has the potential to cause permanent damage to the unit.
The open circuit voltage of the PV strings cannot exceed the maximum input voltage of the inverter.
Only the GOODWE supplied DC connectors are suitable for use.
The positive and negative pole should not be connected to the PE wire (ground wire). Not following this instruction may cause damage to the inverter.
Do not connect the positive or negative poles of the PV string to the PE wire. Not following this instruction may cause damage to the inverter.
Red represents positive, black represents negative

There are four types of DC connectors, DEVALAN, MC4, AMPHENDL H4 and QC4.10 series.

Overvoltage Category Definition

Category I: applies to equipment connected to a circuit where measures have been taken to reduce transient overvoltage to a low level.
Category II: applies to equipment not permanently connected to the installation. For example, appliances, portable tools and other plug-connected equipment;
Category III: applies to fixed downstream equipment, including the main distribution board. For example,switchgear and other equipment in an industrial installation;
Category IV: applies to equipment permanently connected at the origin of an installation
(upstream of the main distribution board). For example, electricity meters, primary overcurrent protection equipment and other equipment connected directly to outdoor open lines

Environment Category Definition

Outdoor : the ambient air temperature is -20~50℃. Relative humidity range is from 4% to 100%, applied to PD3.
Indoor unconditioned: the ambient air temperature is -20~50 ℃. Relative humidity range is from 5% to 95%, applied to PD3.
Indoor conditioned: the ambient air temperature is 0~40 ℃. Relative humidity range is from 5% to 85%, applied to PD2.

Pollution Degree Definition

Pollution degree 1: No pollution or only dry, non-conductive pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution occurs. However, a temporary conductivity occasionally caused by condensation must be expected.
Pollution degree 3: Conductive pollution occurs. Or dry, non-conductive pollution becomes conductive due to condensation, which is expected.
Pollution degree 4: Persistent conductive pollution occurs. For example, the pollution cause by conductive dust, rain and snow.
