9.1 Function Description
The Logger1000 not only serves as a communication management device of single
PV array/plant, but also has the power regulation function. Multiple regulation
manners can meet different regulation requirements. The Logger1000 can regulate
the power output of the SUNGROW inverter, and the regulation mainly includes
active power control and reactive power regulation.
The Logger1000 can control device power output according to the local preset
instructions. In addition, it can receive regulation instructions via the remote
communication (IEC104, MODBUS, and TCP), AI, and dry contact (DI).

The Logger1000 supports closed-loop power regulation. The regulation accuracy
and real-time performance can be further improved by adding an energy meter.
The Logger1000 supports fast instruction transfer channels (ms-level processing
delay) while ensuring that the dispatching instructions are correctly transmitted to
all inverters.
