Megamic's WiseNet system consists of wireless nodes that each measure the current of a single solar string with high accuracy. The nodes transmit the string current data to a central node wirelessly. The central node can interface with a SCADA system or transmit the data over the internet for remote monitoring of string performance over time. Each node is powered by one of the solar panels in its string and does not require batteries or maintenance. The system can monitor up to several hundred strings and transmit data as frequently as every minute.
