Step
injection
module
Refers to a control
module that injects step
reactive power to
promote frequency offset
when the offset deviation
of grid voltage and
frequency is very small.
When islanding occurs,
the inverter and load
reaches balance.

Voltage rise
suppression
The Japanese standard
requires that the inverter
should control the active
power and reactive
power when the output
voltage exceeds a certain
value to ensure the grid
voltage stability.

adjustment
point
The Japanese standard
requires that the inverter
should adjust the reactive
power to prevent the grid
voltage from rising when
the output voltage
exceeds a certain value.
