Local Isolation: Using the Sun's Energy - Circuit Cellar
In last month’s column, I discussed a low-voltage solar energy system I built for lighting my Scout troop’s large storage shed. I described the battery I chose, and the Modbus protocol with RS-485 serial communication used for remote monitoring of the system’s performance (“sniffing” or listening to communication on the bus, and decoding each message). This month I expand on this node’s capacity to do much more than just listen and decode.
