3.3 Features
Module level monitoring
The inverter supports 4 independent Maximum Power Point Tracking(MPPT for short). Each
MPPT is connected to one PV module and tracks the maximum power point of each module.
Power derating
To satisfying the local laws or regulations and ensuring a safe operation, the inverter will
automatically reduce the output power when the operating environment is not ideal.
The following are the factors that may occur power derating. Please try to avoid then during
operations.
• Unfavorable environmental conditions, e.g., direct sunlight, high temperature, etc.
• Inverter's output power percentage has been set.
• Over-frequency derating.
• Higher input voltage value.
• Higher input current value.
Communication
Setting the inverter via bluetooth in a short distance; or connecting the inverter to the server via
WiFi to monitor the inverter and power plant working status.
• Bluetooth: meets Bluetooth 5.1 standard
• WiFi: supports 2.4G frequency band. Set the router to 2.4G or 2.4G/5G mode.
• The router wireless signal name supports a maximum input of 32 bytes.
• Check the WiFi signal intensity via SolarGo app. It is recommended to move the router closer
to the inverter or clear the signal blocking objects to enhance the signal intensity when it is
less than -60.
When multiple inverters are connected, these inverters can form a tree network via WiFi and
communicate with the server through the one selected as the communication root node. Specify
one inverter as the communication root node via SolarGo app if the communication is poor. For
more detailed instructions, refer to the SolarGo APP User Manual

Slow blinking green = Equipment on and in the standby mode.
Fast blinking green = equipment starting and in the self-check
mode.
Steady green = The four PV inputs are available, and the invert-
er is feeding power to the grid properly.
Blinking green and red = Not all PV inputs are available, but the
inverter is still feeding power to the grid.
The four blinks represent the status of four inputs PV1, PV2, PV3
and PV4 respectively. Red blinks indicating abnormal PV input,
green blinks indicating normal PV input.
Example: As shown on the left, PV1 is abnormal and PV2, PV3
and PV4 are normally working.
Single blinking red = Utility grid loss.
Double blinking red = Utility grid fault.
Steady red = Equipment fault.
Fast blinking green and red = Updating software.
