  • Page 26: Notice And Safety Instructions

    This section contains important information and instructions to safely install an array of alternating current photovoltaic solar modules (AC Unison module) and the Data Logger. Failure to follow these instructions can result in equipment damage or failure, or personal injury, and may void the system warranty, and/or property damage.
  • Page 27 Some authorities having jurisdiction (AHJ) may require a separate disconnect next to the AC Unison module system as well as a readily accessible disconnect. The AC cables and connectors are listed for outdoor use with AC Unison module applications and are rated for 20A, and with insulation rated to a maximum temperature of 90°C.
  • Page 28 Do not expose the AC Unison module to excessive loads on the surface of the AC Unison module or twist the frame. The glass may break. Do not stand or step on the AC Unison module. The glass may be slippery, and there is a risk of injury or electric shock if glass is broken.
  • Page 29 Always wear protective head gear, insulating gloves and safety shoes (with rubber soles). Due to the risk of electrical shock, do not perform any work if the terminals of the AC Unison module are wet. Do not wear metallic jewelry which may conduct electricity and enable electric shock during installation.
  • Page 30 NOTE: Proper grounding of the AC Unison module system will ensure full warranty coverage. Although highly recommended, the installation of auxiliary lightning protection systems / components is not specifically tied to the AC Unison module’s warranty. The conductor used for lightning protection from the structure to the grounding electrode system must not be run inside the same conduit that contains the EGC and AC circuit conductors.

  • Page 32: Additional Information On Ac Module Planning & Preparation

    6.0 Additional Information on AC Module Planning & Preparation For the purpose of this document, a circuit is defined as one to seventeen AC Unison modules connected in parallel to a dedicated 20A branch circuit. An array refers to the entire installation of one or more strings connected to the structure’s AC service equipment.

  • Page 33: Pv System Attachment Mounting Considerations

    PV modules should be tilted so that the energy production from the PV modules will be maximized on an annual basis. The tilt angle of the PV module is measured between the surface of the PV module and a horizontal ground surface. AUO PV modules produce the most power when the sun’s rays strike the module perpendicular to the module surface.

  • Page 36: Data Logger

    The AUO Data Logger is a gateway device that uses Power Line Communications (PLC) to collect status and performance data from AC Unison modules. Using broadband Internet, the Data Logger then forwards the collected data to the Solar Monitoring System at five minute intervals. When necessary, the Data Logger automatically downloads and installs enhancements, which can include defect fixes, to the software on the Data Logger or, on rare occasions, to the firmware on the micro-inverter.

    Solar Monitoring System, the Data Logger must be connected to a 10/100Base-T network router using an Ethernet cable. When connected to the Internet, the Data Logger periodically uploads site- and module-level data to the AUO Solar Monitoring System. If a network or DHCP is not available, the Data Logger uses its default IP address, 192.168.100.1.
