Output mode:
ATA can operate in:
Single mode,
Parallel mode,
Phase S mode,
Phase R mode,
Phase T mode.
Single Mode:
When the units are used in parallel with
single phase, please select “PAL” in
program 28.
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.
Besides, power saving function will be
automatically disabled.
Parallel Mode:
Phase S (L1):
Phase R (L2):
Phase T (L3):

PV judge condition
(Only apply for
setting “Solar first”
in program 1:
Output source
priority)
One Inverter (Default):
When “ONE” is selected, as long as one of
inverters has been connected to PV
modules and PV input is normal, parallel or
3-phase system will continue working
according to rule of “solar first” setting.
For example, two units are connected in
parallel and set “SOL” in output source
priority. If one of two units has connected
to PV modules and PV input is normal, the
parallel system will provide power to loads
from solar or battery power. If both of
them are not sufficient, the system will
provide power to loads from utility.
