Safety

The inverter has been designed and tested strictly according to international safety regulations. Read all safety instructions carefully prior to any work and observe them at all times when working on or with the inverter.

Incorrect operation or work may cause:

injury or death to the operator or a third party; or
damage to the inverter and other properties.
Please follow the safety instructions related to the PV strings and the utility grid.

DANGER

Lethal voltage!
PV strings will produce electrical power when exposed to sunlight and can cause a lethal voltage and an electric shock.
Only qualified personnel can perform the wiring of the PV panels.

NOTICE

Danger to life from electric shock due to lethal voltage!
All electrical connections must be in accordance with local and national standards.
Only with the permission of the utility grid, the inverter can be connected to the utility grid.

Inverter

The icons on the inverter body are as follows.

EU Declaration of Conformity

within the scope of the EU directives

Low Voltage Directive 2014/35/EU (LVD)
Electromagnetic compatibility 2014/30/EU（EMC)
Restriction of the use of certain hazardous substances 2011/65/EU and 2015/863/EU (RoHS)
SUNGROW confirms herewith that the products described in this document comply with the fundamental requirements and other relevant provisions of the abovementioned directives.
The entire EU Declaration of Conformity can be found at support.sungrowpower.com.
The communication module that comes with the inverter and the technical parameters of wireless communication are listed in the table below.
The model of the communication module delivered shall prevail. The EU Declaration of Conformity for the communication module can be found at support.sungrowpower.com.

WiNet-S

Radio technology WLAN 802.11b/g/n20/n40
Radio spectrum: 802.11b/g/n20 2412 MHz ~ 2472 MHz
- 802.11n40 2422 MHz ~ 2462 MHz
Maximum transmission power ≤ 20 dBm
Technical parameters listed above apply to EU countries only.

DANGER

Danger to life from electric shocks due to live voltage
Do not open the enclosure at any time. Unauthorized opening will void warranty and warranty claims and in most cases terminate the operating license.
When the enclosure lid is removed, live components can be touched which can result in death or serious injury due to electric shock.
Lethal danger from electric shock due to possibly damaged inverter
Only operate the inverter when it is technically faultless and in a safe state.
Operating a damaged inverter can lead to hazardous situations that can result in death or serious injuries due to electric shock.
WARNING Risk of inverter damage or personal injury
Do not connect or disconnect the PV and AC connectors when the inverter is running.
Wait at least 10 minutes for the internal capacitors to discharge after all electric devices are removed and the inverter is powered off.
Ensure that there is no voltage or current before connecting or disconnecting the PV and AC connectors.
WARNING All the warning labels and nameplates on the inverter body.
must be clearly visible; and
must not be removed, covered, or pasted.
CAUTION Risk of burns due to hot components!
Do not touch any hot parts (such as the heat sinks) during operation. Only the DC switch and the LCD panel can safely be touched at any time.
NOTICE Only qualified personnel can perform the country setting. Unauthorized alteration may cause a breach of the type-certificate marking.
Risk of inverter damage due to electrostatic discharge (ESD)!
By touching the electronic components, you may damage the inverter.

For inverter handling, be sure to:

avoid any unnecessary touching; and
wear a grounding wristband before touching any connectors.
