AS4777.2:2020 Product Updates

Inverters currently in testing for certification and to be compliant to AS/NZS 4777.2:2020. CEC listing will follow after this

Last update: 13/12/2021

Inverters being re-certified that are already in distributors stock will require a firmware update to achieve compliance to AS4777.2:2020. A detailed procedure on how to do this will be provided at a later stage once the certification process has been completed. New inverters from factory post-certification will already have the latest firmware and will have its external sticker updated showing compliance to AS4777.2:2020.

Current changes to compliance processes are providing alternative pathways given the current global DC Isolator certification issues at hand while also not compromising on safety. These issues are affecting a large portion of inverter manufacturers in Australia and the issue is being hotly debated by regulatory bodies during this time. Delta aims to keep our sales partners in the loop as much as possible to be able to deliver a safe and compliant product in a timely manner.
