IEC TS 62257-7:2017 specifies the general requirements for the generators in decentralized rural electrification systems. This document is a general introduction followed by more specific documents dedicated to the generation technologies which are the most currently used in rural electrification projects. This new edition includes the following significant technical changes with respect to the previous edition: removed the word small from the description of the PV systems, and removed the power limit (100 kVA); increased the relevant voltage levels to 1 000 V (AC) and 1 500 V (DC).
