Enecsys picks Ember's ZigBee technology to optimize solar

Boston and Cambridge, England, October 3, 2011 — Enecsys Limited has teamed with Ember to bring wireless ZigBee communications to rooftop solar photovoltaic systems so that households and businesses can better monitor and optimize their systems' performance.

Enecsys has integrated Ember's ZigBee system-on-chip and ZigBee PRO software into its SMI series of micro inverters, which convert the DC output of solar panels into AC for connection to the electricity grid.

Unlike traditional centralized string inverters, Enecsys' micro inverters connect to each module of a solar PV system, or each pair of modules in the case of the "Duo" product. They deliver better energy harvest, higher reliability, longer life expectancy and greater solar PV design flexibility.

Each Enecsys micro inverter has Ember's ZigBee technology built-in to communicate detailed information on the performance of each solar module, which string inverters cannot do.

The Ember-enabled micro inverters provide real-time and historical data to a user-friendly graphical interface so that users can ensure PV system performance is optimized over the life of its installation.

The ZigBee-based monitoring system can be used to detect performance issues and pinpoint the exact location and nature of the problem, such as shading or dust on a section of a module.

The micro inverter also connects to an Ember-enabled ZigBee-to-IP gateway that enables monitoring from any Internet device. And an Enecsys iPhone app enables remote monitoring from anywhere in the world using the mobile device.
