4.4. Test run
Before turn on the inverter, please confirm:
a)
Three phase five wires (R/S/T/N/PE) 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)
The unused terminals are covered.
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.
