Abstract

IEC TS 62786-2:2026 supplements IEC TS 62786-1, and specifies requirements for the connection of the solar photovoltaic energy system or photovoltaic generating system (PV system) with an electric power network, or the network. This document covers all sizes of PV systems connected to low voltage or medium voltage power networks and gives typical requirements for various sizes of PV systems.In this document, requirements for grid-connected PV systems are applied to those categorized as grid tied, grid tied with storage and grid tied with storage and back up. Mini-grid and Micro-grid are out of scope. Those types of PV systems with possible elements are described in 4.3.This document specifies the following technical requirements for the PV system:- reference points of requirements,- elements and configuration,- basic operation,- protection and fault ride through function,- power control and grid support function,- electromagnetic compatibility for low frequency conducted disturbances,- information exchange for remote monitoring, control, and configuration.
