WG 1 - TC 23/SC 23K/WG 1

IEC 62991:2022 applies to source switching equipment, hereafter referred to as SSE, for household and similar uses, primarily intended to be used for energy efficiency (EE) purposes with local production and/or storage of energy.
SSE is intended to be installed in low voltage prosumer electrical installations (PEI) to deliver the electrical energy:
either to current-using equipment (direct feeding mode or island mode);
or to the grid (reverse feeding mode).

IEC 62962:2019 The purpose of this document is to provide requirements for equipment to be used in energy efficiency systems. This document covers load-shedding equipment (LSE).
Guidelines relating to safety for LSE as given in IEC Guide 110 have been followed.
This document applies to load-shedding equipment for household and similar uses. The load-shedding function is used in energy management systems to optimize the overall use of electrical energy including production and storage. Load-shedding can be used for example for energy efficiency purposes as per IEC 60364-8-1:2019.
