Selectable option
When the units are used in parallel with
Single:
single phase, please select "PAL" in
program 28.
It is required to have at least 3 inverters or
maximum 6 inverters to support
Parallel:
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
L1 phase:
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.
L2 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.
L3 phase:
Besides, power saving function will be
automatically disabled.
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.
One Inverter
For example, two units are connected in
parallel and set "SOL" in output source
(Default):
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.
When "ALL" is selected, parallel or 3-phase
system will continue working according to
rule of "solar first" setting only when all of
inverters are connected to PV modules.
For example, two units are connected in
parallel and set "SOL" in output source
All of Inverters:
priority. When selecting "ALL" in program
30, it's necessary to have all inverters
connected to PV modules and PV input is
normal to allow the system to provide
power to loads from solar and battery
power. Otherwise, the system will provide
power to loads from utility.
