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.
