29 Low DC cut-off voltage
Default setting: 42.0V
If self-defined is selected in program 5, this program can be set
up. Setting range is from 40.0V to 48.0V. Increment of each
click is 0.1V. Low DC cut-off voltage will be fixed to setting value
no matter what percentage of load is connected.

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 the 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 the 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.
All of Inverters:
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 priority.
When “ALL” is selected 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.
