ON/OFF Control
In this mode, the system will control
the load operation according to the
setting. Set to OFF in the following
example.
Fig. 10-3 DO Operation in ON/OFF Control
Optimized Control
he system will control the load operation according
to the power optimization algorithm of energy
management.
During the setting interval, the DO function will be
enabled to power on the load if the excess PV energy
exceeds the optimized power value.
Notice:
y
The optimized mode is disabled in an off-grid system.
y
When the existing system is enabled, the upper limit of optimized power is the
sum of the rated power of the hybrid inverter and the rated power of the existing
PV system.
y
Once the optimized mode is enabled, the DO relay will not disconnect until 20
minutes after the DO connection.
Take 09:00 am
–09:30 am and the optimized power of 1000 W as an example.
