Please nominate exemptions that are applicable to this submission. For any other exemptions, please submit a Technical Rules Exemption Request (TER).

Yes/No/N/A	Conditions	General Exemption Clause	Reason / Site Context for Exemption Provide a brief, site-specific reason for selecting this exemption
1	LV connection points only	3.6.7.2(a) Main Switch The applicant requests exemption from 3.6.7.2(a) Main Switch to the effect that alternative arrangements comprising of clearly labelled multiple main switches will be accepted, provided that response to faults on the network or on the User's installation is not adversely affected by this change.
2	HV or LV connection points ≤ 200kVA aggregate inverter capacity only	3.6.10.1 & 3.6.10.3 Protection Relay/Interface Protection The applicant requests exemption from Clause 3.6.10.1 and Clause 3.6.10.3 to the effect that all protection functions required under Clause 3.6.10.1 and Clause 3.6.10.3 shall be provided by the integrated control and protection apparatus of an AS/NZS 4777.2:2020 compliant inverter without the requirement for duplication via an independent protection relay.
3	N/A if requesting #2 HV or LV connection points	3.6.10.1(a) Protection Location The applicant requests exemption from Clause 3.6.10.1(a) to the effect that the protection relay need not be located at the connection point provided that the site satisfies the conditions provided in the Technical Rules Conditional Exemption Notification.

4	N/A if requesting #2 HV or LV connection points	3.6.10.1(d) Protection Duplication The applicant requests exemption from Clause 3.6.10.1(d) to the effect that one IEC 60255 compliant external protection device in conjunction with AS/NZS 4777.2:2020 compliant inverters will be acceptable with respect to the duplication of protection.
5	N/A if requesting #2 HV or LV connection points	3.6.10.1(g) NVD and SEF Protection The applicant requests exemption from Clause 3.6.10.1(g) to the effect of not requiring NVD earth fault protection on the HV distribution system for an LV connected inverter energy system. This exemption assumes that the external protection relay is IEC 60255 compliant, has rate of change of frequency (RoCoF) protection with a setting of 4 Hz/sec and a sampling rate of 4 cycles, and is complemented by the use of inverters that comply with AS/NZS 4777.2:2020 and IEC 62116.
