The Technology behind Active Array™

The core technology of Active Array™ is the Active Tag, a small low cost device integrated into the junction box of each PV module which monitors the performance and condition of the module.

It transmits this data wirelessly to the Active Combiner which analyses the data from each module and string and is able to automatically intervene on danger conditions or simply alert the user for less serious performance or safety problems.

The Active Tag

  • Monitors the module performance and other environmental conditions
  • Independently isolates the module in response to an abnormal fault and danger conditions
  • Transmits all data to the Active Combiner
  • Isolates the PV module when not “in service”
  • Assigns an individual identification code to each module, used both for communication and asset tracking purposes

Active Combiner

The intelligence and management console of Active Array™ is the Active Combiner. The Active Combiner is a multi-channel device, able to manage multiple strings of Active Array™ modules.

  • Manages up to 8 strings of Active Array™ modules
  • Combines 8 strings down to two outputs with full intelligent reverse current protection
  • Provides both a manual switch interface and software based intelligent switching to isolate individual strings on request or in response to fault conditions
  • Measures performance of individual strings of Active Array™ modules allowing diagnosis of voltage drops or fault conditions
  • Communicates with the Active Tags to manage safety and performance in response to fault conditions
  • Communicates with Active Tags to retrieve and store performance and fault condition data
  • Provides a wireless PC management interface for control and data analysis

Active Array™ PC Management Console

The Active Array™ Management Console is a PC user interface which maintains live and historical module level performance data for each module and provides the unique ability to control and isolate individual modules and strings.

  • Immediate safety alerts
  • Live module data analysis
  • Historical data analysis
  • Clear Array Summary data for public view
  • Drill down capability and command interface for individual module control
