Communication and Monitoring

8.2.2 RS485 Communication

RS485 is generally for at most 32 inverters communication at the same time. But the length of

communication wire should be≤1200m. You can read and analyse data by PC if the system is equipped

with Solar-Log200/500/1000. Please refer to Solar-Log200/500/1000 manual for more information.

Figure 23 RS-485 jack

Two types of cable must be prepared before using Solar-Log to monitor mult-inverters.

The communication cable between inverter and inverter:

1. Prepare two 8-PIN RJ45 modular plug, hold the RJ45 modular plug with the 'clip' on the bottom,

the 'opening' (where you insert the cable) facing you, the order number is 1 to 8 from left to right,

as figure 24.

2. Use a length of communication cable, then push the 8 color wires into the modular plug follow the

same order as below.
