Specifies requirements for the installation of inverter energy systems with ratings up to 10 kVA for single-phase systems, or 30 kVA for three-phase systems, onto the low-voltage electricity distribution network (grid).

This Standard specifies the electrical installation requirements for inverter energy systems and grid protection devices with ratings up to 10 kVA for single phase units, or up to 30 kVA for three-phase units, for the injection of electric power through an electrical installation to the electricity distribution network.NOTES: 1 Although this Standard does not apply to larger systems, similar principles can be used for the installation of such systems.2 This Standard does not cover detailed installation requirements for the energy source(s) and its associated wiring.
