To meet growing global demand for ISO-compliant field testing and certification, QuietGrid Technologies has entered new partnerships with certified acoustic testing labs in Suzhou, China and Hamburg, Germany. These partnerships will support ISO 9614-1 and ISO 3744 tests for BESS containers, PCS, inverters, and chillers deployed in high-regulation zones.

The expansion allows QuietGrid to support 72-hour turnaround for noise validation and environmental compliance documentation across multiple continents.
