Power line carrier communication
Uses the power of the power line through
alternating current as the carrier to modulate the high-frequency carrier frequency (
) in
Alternating current wire transmission allows communication between inverters or between inverters and computers, real-time transmission of power generation data, sunlight brightness data, and monitoring of all functions of the inverter.

Level power search
In cloudy weather, when the output current of the solar cell is extremely small, the inverter automatically turns on the
level power search function.
The program automatically performs
times of power adjustment
The current is adjusted downward from the maximum to the minimum direction
During the automatic adjustment process, you will see
The light keeps flashing, and the power will be
as the starting point, increase the output power to the maximum power point, restart at most
times, and then enter the power Locked state, when locked
the light is always on.
When performing the
stage power search procedure, the time required is
