5.7.3 Three-phase Balance
When using APsystems single-phase micro-inverse to form a
three-phase system, the three-phase balance function can be
turned on to ensure that the three-phase current difference does
not exceed 16A.
The three-phase balance function can be connected to the
detection current through an external CT, and the response speed is
faster; it can also be collected by the ECU to collect micro-inverse
data on each phase for detection. At this time, no external CT is
required, but the response speed will be slow, and the general
maximum duration is 5 minutes.
And at this function, you need to register
separately according to the micro-inverse
serial
number
of
each
phase
in
the
three-phase configuration.
5.8 Modbus Settings
As shown in Figure 15 below, RS485 interface is located under the ECU.
It can be connected by Serial line.
