The modifications proposed here are a series of issues raised since the last modifications to EREC G98 and G99. They span all Types of Power Generating Modules (PGM), i.e. Types A – D and include some new requirements as well as clarifications to existing requirements. This proposal also includes minor associated modifications to the Distribution Code.
