The CEC has announced that all listings for inverters which have been tested and certified to AS/NZS 4777.2:2015 must be updated to AS/NZS 4777.2:2020 by 18 December 2021. This means that any Certificate Holder or any Australian supplier applying the for CEC rebate for these products must obtain an endorsed test report to AS/NZS 4777.2:2020 before this date and submit it to us for a technical modification, application fee AUD 500. We will issue an addendum certificate which will allow the Certificate Holder to extend their CEC listing.
CEC已经发表告示，要求所有登记在案的，按照4777.2:2015测试并认证的逆变器， 都必须在2021年12月18号前，更新标准至AS/NZS 4777.2:2020. 这意味着任何一个为该类产品申请CEC折扣的证书持有人或者澳洲供应商，务必在该日期前获取一份测试了AS/NZS 4777.2:2020的完整报告并提交我司进行证书技术性修改.申请费为500澳币.我司将签发一份证书附录，证书持有人可将此附录提交给CEC备案.

The new AS/NZS 4777.2:2020 is quite different to the previous edition and a full new test report will be required. Please pay attention to the following points:
新版本AS/NZS 4777.2:2020与之前版本有很大区别。它要求产品有新的完整的测试报告。请注意以下几点：

Clause 4.2:
Based on the advice received from the Standards Committee and the CEC, where an inverter has 2 relays in series as the automatic disconnection device, the requirements of Clause 4.2 can be met by the relays working together – the requirements does not need to apply to each individual relay.
条款4.2：
基于标准委员会和CEC 给出的建议，逆变器当中如果有2个串联的继电器作为自动断联装置，条款4.2的要求可以通过继电器同时工作来满足。此要求不需要适用于单个继电器。

Testing to different Regions
Where AS/NZS 4777.2:2020 specifies different region settings, the test report should show the tabular (and where required by the Standards graphs) results for testing to Australia Region A, a table of results for testing to Australia Region B and C are not required however the test report should state that the inverter also has settings for Australia Region B and Australia Region C with limits as setpoints as stated in AS/NZS 4777.2:2020.
不同地点测试
AS/NZS 4777.2:2020详细指出了不同地点的设置，测试报告应该包含针对澳大利亚地区A的测试结果表格（标准中要求的场地），不需要有澳大利亚地区B和C的测试结果表格， 但是测试报告应该阐明逆变器同样有满足AS/NZS 4777.2:2020中的澳大利亚地区B和地区C设定点标准的设置并写明设置值。
