18 JA N UA RY / F E B RUA RY 2 0 1 9 T oday's solar systems require a more robust communication architecture to manage significantly more data points and in-field software updates, and this need was the driving force behind APsystems's newest microinverter. Despite being the most powerful microinverter you'll find on the market, the QS1 debuted rather quietly at Solar Power International last year — a debut that even caught director of marketing Jason Higginson off-guard. But hey, when a product is ready, it's ready. Key to the QS1 development was incorporating a high-speed wireless Zigbee connection instead of Power Line Communication (PLC). The dif- ference is measured in speed of both installation (75 percent reduction in installation time) and data transmission. "With the smart grid, and a very smart inverter, there are a considerable number of data points that need to be communicated back from the microin- verters through the gateway and to the monitoring platform in the cloud," Higginson explains. "This means a steady stream of data is constantly flow- ing from the inverter to the internet. When systems like the QS1 and YC600 apply remote firmware upgrades, this creates a demanding bidirectional data flow and, for MLPE systems, traditional powerline communication isn't going to cut it." The QS1 employs high-speed wire- less Zigbee, which is up to three times faster than conventional powerline com- munication (PLC), creating a local BOS NEW IN Need for Speed Inside the upgrades to the most powerful microinverter on the market By Chris Crowell APsystems QS1 Microinverter Datasheet
