Function Description

The inverter is equipped with the following functions:
Conversion Function
The inverter converts the DC current into grid-compatible AC current and feeds the AC cur-
rent into the grid.
Data Storage
The inverter logs running information, error records, etc.
Parameter Configuration
The inverter provides various settable parameters. Users can set parameters via the App to
meet the requirements and optimize the 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 through communication cables or wire-
less 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 unex-
pected damage.
Protection Function
The protective functions are integrated in the inverter, including anti-island protection, DC re-
versed polarity protection, AC short circuit protection, leakage current protection, etc.
Ripple Control
The inverter provides terminals (DRM) for connecting to a Ripple Control Receiver (RCR).
After the connection, the grid dispatching center issues regulation instructions via dry con-
tact (DI). The inverter can control power output according to the local preset instructions.
PID recovery
The PID function may not be applicable in some areas. Please consult SUN-
GROW for details.
