2.1 GENERAL CONDITIONS FOR TESTS
The general conditions for tests contained in Appendix A shall apply to all tests in this Standard.
2.2 SPECIFICATIONS
For testing purposes. the manufacturer or importer shall provide the following values. where applicable.
NOTE: If any of the following values are adjustable, the range of values and the factory settings are to be provided.
(a) Nominal d.c. input voltage.
(b) D.C. operating voltage range.
(c) Nominal a.c. output voltage (single-phase or three-phase).
(d) Nominal a.c. frequency and Frequency range.
(e) Power factor range.
(f) Rated d.c. charging current (interactive inverters and inverter-cliargers only).
(g) Continuous output power rating at unity power factor at 25°C for at least 5 h with nominal d.c. input voltage.
(h) Continuous output power rating at unity power factor at 40°C for at least 5 h with nominal d.c. input voltage.
(i) Continuous apparent power rating at 0.75 power factor at 25°C.
(j) 30 mm rating—the maximum output for a 30 mm period with nominal d.c. input voltage.
(k) Surge ratings—the maximum output for a 3 s period with iiorninal d.c. input voltage at 25°C and 40°C.
(I) Demand start load and demand stop load (the load required to bring the inverter into active mode and standby mode respectively).
(m) All d.c. input voltage disconnect and reconnect set points.
(n) Battery charging stages. and the duration, voltage andIor current specifications for each charging stage.
NOTE: It’ values for (1). (m) and (n) are adjustable by adaptive control algorithms (e.g. temperature compensation of battery-charging points), the information required in order to test these settings needs to be provided.
3..3 Statement of unsuitability to run motor loads
If the inverter is unsuitable for supplying motor loads, the operating instructions supplied with the inverter shall clearly state this.
3.9 CHARGING EFFICIENCY AND CURRENT THD
Interactive inverters and inverter-chargers shall be capable of transferring power from the a.c. terminals to the d.c. battery terminals with the charging efficiency as declared by the manufacturer.
The total harmonic distortion of the inverter a.c. current shall he assessed on the basis of the limits specified in Clause 3.11. Table 9.
Compliance shall be verified by type testing in accordance with Appendix K.
3.10 THREE-PHASE INVERTERS
A three-phase inverter shall be capable of supplying balanced three-phase voltages under the following loading conditions:
(a) Balanced three-phase resistive load equal to 100% of the inverter rating.
(b) Resistive load on one phase equal to 100% of the inverter’s per phase rating and no- load on the remaining two phases. This loading condition applies to all three phases.
The voltage on each phase and neutral shall comply with the supply voltage requirements specified in AS 60038 for Australia and NZS/IEC 38 for New Zealand for a.c. systems having a nominal system voltage between 100 V and 1000 V under all loading conditions specified above. Compliance shall be verified by type testing in accordance with Appendix L.
3.11 PERFORMANCE CLASS
The inverter shall be classified as one of the following perflrmance classes by means of evaluating its performance against the requirements of this Standard in respect of each of the following criteria: efficiency, no-load power losses, standby losses, voltage regulation. voltage harmonic distortion and current harmonic distortion (for charging mode only).
