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 COM100 can regulate the power output of
the SUNGROW inverter, and the regulation mainly includes active power control and
reactive power control.
The COM100 can control device power output according to the local preset instructions.
In addition, it can receive dispatch 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 the Smart 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.
