User Manual 2 Product Description
DANGER
If the lightning level exceeds the protection level of the product, surge protection and
overvoltage protection may fail, resulting in electric shock and fatal injury!
2.6 Function Description
The inverter is equipped with the following functions:
Conversion Function
The inverter converts the DC into grid-compatible AC and feeds the AC into the grid.
Data Storage and Display
The inverter logs system information like running information, error records, etc.
Parameter Configuration
The inverter provides various parameter configurations. Users can set parameters via the App
to meet different needs and optimize the inverter performance.
Communication Interface
The inverter is designed with standard RS485 communication interfaces and communication
accessory port.
• The standard RS485 communication interfaces are used to establish communication with
monitoring devices and to upload monitoring data to a monitoring background through
communication cables.
• The communication accessory port is used to connect communication module manufac
tured by SUNGROW, and upload monitoring data by means of wireless communication.
The inverter can be connected to communication devices via either of the two interfaces. When
communication is established between the inverter and the communication devices, users can
view inverter information or set inverter parameters, such as running parameter and protection
parameter, through the iSolarCloud.
It is recommended to use the communication module from SUNGROW. Using a
device from other companies may lead to communication failure or other unexpected
damage.
Protection Function
The inverter is equipped with anti-island protection, LVRT/HVRT, DC reversed polarity protec
tion, AC short circuit protection, leakage current protection, DC over-voltage/over-current pro
tection, etc.
