The inverter high voltage disconnect and reconnect set points shall be declared by the manufacturer or be adjustable. The high voltage disconnect and reconnect voltage, if applicable, shall agree with the set points within +2%. Compliance shall be determined by type testing in accordance with the d.c. voltage disconnect and reconnect set points test described in Appendix D.
If the unit has adjustable set points, the default values, or a set point agreed with the client or manufacturer, should be used for testing purposes.
Where the inverter manufacturer has specified a temperature corresponding to the set points, this temperature shall be used as the reference temperature for the test. Where the inverter manufacturer has not specified such a temperature, a reference temperature of 25°C shall be used. Where the inverter manufacturer has specified a temperature coefficient for the set points, the inverter shall be tested with the battery temperature sensor at the reference temperature and at 40°C.
NOTE: Disconnect and reconnect overvoltage set points are often used in stand-alone power systems with batteries to protect the battery from overvoltage conditions.
The inverter shall have low input voltage disconnect and reconnect set points. These set points shall be declared by the manufacturer or be adjustable. The low voltage disconnect and reconnect voltages shall agree with the set points within±2%. Compliance shall be determined by type testing in accordance with the d.c. voltage disconnect and reconnect set points test described in Appendix D.
If the unit has adjustable set points, the default values, or a set point agreed with the client or manufacturer, should be used for testing purposes.
Where the inverter manufacturer has specified a temperature corresponding to the set points, this temperature shall be used as the reference temperature for the test. Where the inverter manufacturer has not specified such a temperature, a reference temperature of 25°C shall be used. Where the inverter manufacturer has specified a temperature coefficient for the set points, the inverter shall be tested with the battery temperature sensor at the reference temperature and at 40°C.
NOTE: Disconnect and reconnect under-voltage set points are required in stand-alone power systems with batteries to protect the battery from under-voltage conditions.AS NZS 5603 pdf free download.
