for detailed information.
L1 phase:
When the units are operated in 3-phase
application, please choose “3PX” to define
each inverter.
It is required to have at least 3 inverters or
maximum 6 inverters to support
three-phase equipment. It’s required to
have at least one inverter in each phase or
it’s up to four inverters in one phase.
Please refers to 5-2 for detailed
information.
Please select “3P1” in program 28 for the
inverters connected to L1 phase, “3P2” in
program 28 for the inverters connected to
L2 phase and “3P3” in program 28 for the
inverters connected to L3 phase.
Be sure to connect share current cable to
units which are on the same phase.
Do NOT connect share current cable
between units on different phases.
L2 phase:
L3 phase:
L1 for split phase:
When the units are operated in split phase
application, please choose “2PX” to define
each inverter.
It is required to have at least 2 inverters or
maximum 6 inverters to support
split-phase equipment. It’s required to
have at least one inverter in each phase or
it’s up to three inverters in one phase.
Please refers to 5-2 for detailed
information.
Please select “2P1” in program 28 for the
inverters connected to L1 phase, “2P2” in
program 28 for the inverters connected to
L2 phase. And it can choose 120°or 180°
phase difference for “2P2”.
Be sure to connect share current cable to
units which are on the same phase.
Do NOT connect share current cable
between units on different phases.
L2 for split phase:
(120° phase difference)
L2 for split phase:
