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 unex-
pected damage.
Protection Function
The inverter is equipped with anti-island protection, LVRT/HVRT, DC reversed polarity pro-
tection, AC short circuit protection, leakage current protection, DC over-voltage/over-current
protection, etc.
PID Recovery
The PID effect (Potential Induced Degradation) of PV modules will cause serious damage to
generated output and yield, which can be avoided or recovered by PID recovery function.
• For positive voltage scheme, after the PID is enabled, the voltage to ground of all PV
strings is greater than 0, and therefore the PV string-to-ground voltage is a positive value.
• For negative voltage scheme, after the PID is enabled, the voltage to ground of all PV
strings is lower than 0, and therefore the PV string-to-ground voltage is a negative value.
