Operation principle and hardware description 49
P958 Harmonics factory
tests
The full-power current harmonics, power factor (PF) and DC injection tests are
done.
The grid voltage and frequency are set to the nominal values in these tests.
While the inverter operates at the nominal active power, current harmonics and
voltage harmonics are measured with a power analyzer. The power factor is
tested and measured with different power levels from 10% to 100%.
P959 Efficiency factory
tests
The efficiency test is done at the ambient room temperature with internal
auxiliary power. The inverter is operated at different power levels and it is
measured with a power analyzer. The euro efficiency is calculated according to
EN 50530.
P960 Custom factory
tests
In addition to the tests done for P945, P957, P958 and P959, power limiting
tests, controllable Power Factor (PF), inverter DC power operation, loss of DC
power, loss of auxiliary power, flicker and anti-islanding with RLC load tests are
done.
