1 Introduction
This quick guide is showing how to commission the SG30/50/110CX inverters and it
is to be read in conjunction with the Sungrow’s User Manuals.
Where more than one inverter, or an energy meter installed, the commissioning and
iSolarCloud connection is done via a Logger1000(Up to 30 devices) and EyeM4(Up to
10 devices).
For export control and load consumption, an energy meter (DTSD1352-C/1(6)A with
external CT) needed to be connected.
All of the components are connected via daisy-chain as per standard RS485 topology.
