Only installation personnel with some communication knowledge
can perform operations described in this chapter.
8.1 Function Description
The COM100 not only serves as a communication management device of a
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 COM100 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 COM100 supports closed-loop power regulation. The regulation accuracy
and real-time performance can be further improved by adding an energy meter.
The COM100 supports fast instruction transfer channels (ms-level processing
delay) while ensuring that the dispatching instructions are correctly transmitted
to all inverters.
