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 quality personnel, in compliance with local electrical standards, and regulations, and following the regula-tions 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 generates dangerous high DC voltage; we strongly opera-tors 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’s built-in protection may be damaged.
• In order to achieve 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.
• The PV is not grounded as default configuration.
• Inverters should not be used in multiple phase combinations.
• The inverters are not suitable for power limitations for multiple inverters.

To ensure that the IP65 protection is maintained, please make sure that the inverter is rigorously packed and its component sealed properly. The GOODWE 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.

• Outdoor: the ambient air temperature is -20~50℃. The relative humidity range is from 4% to 100%, applied to PD3.
• Indoor unconditioned: the ambient air temperature is -20~50 ℃. The 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, pollution is caused by conductive dust, rain, and snow.
