DT/ Smart DT (hereinafter referred to as SDT) 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. As electric and electronic equipment, Safety
Regulation shall be followed during installation and maintenance. Improper operation may bring severe damage to the operator, the
third party and other properties. (DT: Dual-MPPT, Three-Phase, covering 09kW/10kW/12kW/15kW/17kW/20kW/25kW; SDT: Smart
Dual-MPPT, Three-Phase, covering 4kW/5kW/6kW.)
●Installation, maintenance and connection of inverters must be performed by qualified personnel, in compliance 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 terminated at least 5 minutes before performing any
installation or maintenance.
O
●The temperature of some parts of the inverter may exceed 60 C 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.
●Without permission, open the front cover of the inverter is not allowed. Users should not touch/replace any of the components
except for the DC/AC connectors. GOODWE will not bear any consequences caused by unauthorized actions which will lead to
potential injury to people and damage to inverters.
●Static electricity may damage electronic components. Appropriate method must be adopted to prevent such damage to the inverter;
otherwise the inverter may be damaged and the warranty will be annulled.
●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 will be annulled.

●When exposed to sunlight, the PV array will generate very high voltage which will cause potential danger to people. Please strictly
follow the instruction we provided.
●PV modules should have an IEC61730 class A rating.
●If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
●Completely isolate the equipment should : switch off the DC switch, disconnect the DC terminal, and disconnect the AC terminal
or AC breaker.
●Prohibit inserting or pulling the AC and DC terminals when the inverter is working.
●Person could access to inverter status through mobile phone and computer display please refers to chapter 3.4.4 and 3.4.5.

(1) Use the wall-mounted bracket as a template and drill 6 holes on the wall, 10 mm in diameter and 80 mm deep. The inverter sizes
of DT series please refer to Figure 3.3.2-1, and the size of SDT series refer to Figure 3.3.2-2.
(2) Fix the wall mounting bracket on the wall with six expansion bolts in accessory bag.
(3) Hold the inverter by the groove on it, (DT models please refer to Figure 3.3.2-3, and SDT models refer to Figure 3.3.2-4.)
(4) Place the inverter on the wall-mounted bracket as illustrated in Figure 3.3.2-5、3.3.2-6、3.3.2-7.
