Fig. 10-3 DO Operation in ON/OFF Control
Optimized Control
The 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.
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.
Once the optimized mode is enabled, the DO relay
will not disconnect until 20 minutes after the DO
connection.
