ACPV Module Installation Guide
Read this First! This document contains important information and instructions to safely install an array of alternating current photo-voltaic (ACPV) solar modules that have been pre-configured with SolarBridge P250LV-230-AU microinverters from the factory (referred to in this manual as "AC Modules"). Failure to follow these instructions can result in equipment damage or failure, or personal injury, and might void the system warranty. The following symbols are used throughout this document to alert you to important safety information that you will need during the installation: This symbol indicates that failure to follow instructions may result in serious hardware failure. Use caution when completing this task.
This symbol indicates that failure to follow instructions may result in serious personal injury. Use extreme caution when completing this task.
The following labels are used on the microinverter housing: CAUTION - Risk of Electric Shock!
Take note and follow instructions. Failure to follow instructions could result in equipment damage, injury or property damage.
Caution. Hot surface.
Refer to the operating instructions.
IMPORTANT SAFETY INSTRUCTIONS - SAVE THESE INSTRUCTIONS
Perform all electrical installations in accordance with any national and local codes, such as the Australian Standards AS/NZS 3000:2007, AS/NZS 5033 2012, AS 4777.1: 2005, and AS/NZS 1170.2 2011. Only qualified personnel who are accredited by the Clean Energy Council should install and/or replace the AC module.
The microinverter is rated for category III installations. However, in areas with risk of surge conditions due to lightning or grid quality, surge protective devices may be necessary to provide better protection to the microinverter electronics. Refer to AS/NZS 3000 and AS/NZS 1768.
The microinverter is rated IP67 enclosure protection and is suitable for outdoor installations in PV module installations attached directly to the PV module frame.
