What does Revenue grade meter (RGM) mean?

A revenue grade meter is a high-accuracy meter used when energy measurements may support billing, incentives, reporting, or compliance.

How does Revenue grade meter (RGM) affect PV system design, production, or customer expectations?

In solar projects, this term helps teams describe equipment, design assumptions, documentation, or field workflows with less ambiguity. Precise vocabulary reduces mistakes between sales, design, installation, inspection, and support.

Practical design considerations

Use the term consistently across product pages, technical documents, and support content.
