4.5 Other Tests
For Australian requirements, in the THDi test, Zref should be added between inverter and mains.
RA, XA for Line conductor
RN, XN for Neutral conductor
Zref:
RA=0, 24; XA=j0,15 at 50Hz;
RN=0, 16; XN=j0,10 at 50Hz
4.6 Quick Check List to Avoid Danger
1. The inverter must not be installed near flammable or explosive materials, or strong electromag-
netic equipment. Please refer to 2.3.1 Select Mounting Location.
2. Remember that this inverter is heavy! Please be careful when removing it from the packaging.
Please refer to 2.3.2 Mounting.
3. Ensure the battery breaker is off and the battery's nominal voltage complies with EM series
specifications before connecting the battery to the inverter, and ensure the inverter is fully
isolated from PV and AC power. Please refer to 2.4 Electrical Wiring Connection.
4. Ensure the inverter is fully isolated from DC and AC power before connecting the AC cable.
Please refer to 2.4.3 On-Grid and Back-Up Connection.
5. Ensure the AC cable is fully isolated from AC power before connecting the Smart Meter & CT,
please refer to 2.4.4 Smart Meter & CT Connection.
Appendix Protection Category Definition
Overvoltage category definition
Category I
Category II
Category III
Category IV
Applies to equipment connected to a circuit where measures have been
taken to reduce transient overvoltage to a low level.
Applies to equipment not permanently connected to the installation.
Examples are appliances, portables tools and other items of plug-connect-
ed equipment.
Applies to fixed equipment downstream of and including the main
distribution board. Examples are switchgear and other industrial equip-
ment.
Applies to equipment permanently connected at the installation point
(upstream of the main distribution board). Examples are electricity meters,
primary over-current protection equipment and other items of equipment
connected directly to outdoor open lines.
