Page 70: Grid Dispatching
10 Grid Dispatching 10.1 Function Description Logger4000 is equipped with a power control module. The module is used to receive control instructions from the grid dispatch center and send the control instructions to the monitored inverter through the RS485 port, thereby controlling the active power, reactive power, power factor, start/stop of the inverter. - Page 71 Generally, this strategy is used for anti-backflow or avoiding zero power feed-in. The Logger4000 receives the remote scheduling command and will stop querying data during this time period. Query recovery time* After the remote scheduling command is executed, you can continue to query the data.
