SMA RS 485 Communication Cable 50ft
Shielded, twisted pair, low capacitance ideal for RS 485 protocols. Custom built for use between and SBC device or a PC and a Sunny Boy Inverter.
Use with SMA RS 485 Card: Allows remote communications and control between multiple Sunny Boy inverters and Sunny Boy Control units. Installed in places of LCD display, additional cable required between Sunny Boy and SBC or SBC Plus device. Must order SBC device with 485 module.
The RS 485 communication system is for those situations where a power line carrier won't work. When you have to link not just several inverters, but several Sunny Boy Controls, RS 485 is the tool to use.
This current-source bus line system allows simultaneous communication with many nodes to one central controller. And with its ability to link several Sunny Boy Controls the number of Sunny Boy inverters that you can control from one computer becomes virtually infinite.
