The inverter can switch off the DO port by setting different load control modes, thus realising load control. The remote setting interface is shown in the figure below, there are three modes of load control, namely Timing Mode, Switch Mode and Power Optimization Mode.
Timing Mode: In a certain time period, the DO port is enabled.
Instant Mode: Directly set whether the DO port is open or closed.
Power Optimization Mode: Set the start and end time and the specified power value. When the grid-feed-in power reaches the set power value, the DO port function is automatically enabled within the specified time period. The DO port will remain enabled (switch closes) for 20 minutes before checking whether the grid-feed-in power still meets the condition.
To trigger the Power Optimization Mode, two conditions should be met at the same time:
1. The grid feed-in power should be greater than the load power set in Intelligent Mode.
2. At this time, the battery should be in the charging state.
In that case the DO switch will close and the controllable load will be activated.
