2 Safety Measures & Warning
The DNS series inverter of Jiangsu GOODWE Power Supply Technology Co, Ltd. (hereinafter
referred to as GOODWE) strictly conforms to related safety rules in design and test. Safety regula-
tions relevant to the location shall be followed during installation, commissioning, operation and
maintenance. Improper operation pose a risk of electric shock or damage to equipment and
property. (DNS Dual-MPPT, Single-Phase)
• Installation and connection of inverters must be performed by qualified personnel, in compli-
ance with local electrical standards, regulations and the requirements of local power authorities
and/or companies.
• To avoid electric shock, DC input and AC output of the inverter must be disconnected for at least
5 minutes before performing any installation or maintenance.
• The temperature of some parts of the inverter 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.
• Do not open the front cover of the inverter, except operating the wiring terminal (as instructed in
this manual). Touching or changing components without authorization may cause injury to
people, damage to inverters and annulment of the warranty.
• Static electricity may damage electronic components. Appropriate methods must be adopted to
prevent such damage to the inverter; otherwise the inverter may be damaged and the warranty
annulled.
• Ensure the output voltage of the proposed PV array is lower than the maximum rated inut voltage
of the inverter; otherwise the inverter may be damaged and the warranty annulled.
• When exposed to sunlight, the PV array generates dangerous high DC voltage. Please operate
according to our instructions, or it will result in danger to life.
• PV modules should have an IEC61730 class A rating.
• If the equipment is used in a way not specified by the manufacturer, the protection provided by
the equipment's design may be impaired.
• To completely isolate the equipment: switch off the DC switch, disconnect the DC terminal, and
disconnect the AC terminal or AC breaker.
• Insert or pull the AC and DC terminals when the inverter is powered on is prohibited.
• If there are more than 3 PV strings on input side, additional fuse installation will be suggested.
• An earthing photovoltaic system requires the connection of an Arc fault detector on DC side.
• 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 build=in RCMU, type A RCD must be used to avoid
tripping.
• The PV- is not grounded as default configuration.
