1. Have any design tool and how to use it?

Shine Design is the system design software just for inverters, It can conduct installers to figure out panel numbers for a system, panel numbers for each string, and which inverter model is suitable for the system. Moreover, it can print a design report after input all necessary parameters, can calculate DC/AC wire wastage, annual generation, etc.


2. Does the inverter have monitoring solutions for residential system?

For small rating system, we have wired two monitoring solution (ShineNet via RS232 or RS485). (a) Local wireless monitoring solution (ShineVision via RF module communication) (b) Global wireless monitoring solution (WIFI module via WIFI network)


3. Do you have free solution for monitoring?

ShineNet is an inverter monitoring software run in Windows XP, Windows Vista, Windows 7 operating system. It can monitor inverter via RS232 (or RS232 convert to USB cable) and RS485 wire connection. Customers can purchase the cable locally to get the inverter monitored, it is simple.
