•
EMI filters can filter out the electromagnetic interference inside the inverter to ensure that
the inverter meets the requirements of electromagnetic compatibility standards.
•
The MPPT is used to ensure a maximum power from PV arrays at different PV input
conditions.
•
The Inverter Circuit converts the DC power into grid-compliant AC power and feeds it into
the grid.
•
The AC filter filters the output AC component of high frequency to ensure that the output
current meets the grid requirements.
•
The AC relay isolates the AC output of the inverter from the grid, making the inverter safe
from the grid in case of inverter failure or grid failure.
•
The AC SPD provides a discharge circuit for the AC side overvoltage to prevent it from
damaging the internal circuits of the inverter.
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!

Function Description
Basic Function
•
Conversion function
The inverter converts the DC power from the PV array to the AC power, in conformity with
the grid requirements.
•
Data storage
The inverter logs running information, error records, etc.
•
Parameter configuration
The inverter provides various parameter configurations for optimal operation. Parame-
ters can be set via the iSolarCloud App or the cloud server.
•
Communication interface
The inverter is equipped with two communication interfaces.The communication device
can be connected to the inverter via both interfaces.
After communication connection is established, users can view inverter information, op-
erational data and can set inverter parameters 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 un-
expected damage.
