Before turn on the inverter, please confirm:
a)
Three phase five wires (PE/L1/L2/L3/N) cable correctly connected to the inverter AC side
through AC circuit breaker;
b)
The DC cable connected correctly to the inverter DC side through DC circuit breaker, please be
attention to the cable connected to the two string correctly and it’s polarity;
c)

Turn on the inverter:
Step1
: Close the DC and AC circuit breaker;
Step2
: If the solar panels provide enough energy, the power module will work and the LCD panel
will be lit;
Step3
: Then the inverter will turn into self-check mode and the LCD panel will display the remaining
time of connect simultaneously;
Step4
: After the inverter turn into normal mode, it feed electrical energy into grid, and LCD panel
will display the generated electrical energy.
As long as the inverter works, it will automatically track the maximum power point to absorb the
maximum energy from solar. When night comes, the irradiance is not strong enough to provide
energy, the inverter will power off automatically. When the next day comes, the input voltage reaches
the start value, it will start again automatically.
