We Created Compliance as a Service

The compliance pathway for a battery energy storage system varies depending on the scope and complexity of your project.

Atar Fire has designed practical, fixed-priced packages so we can adapt test methods and documentation according to project needs with timelines ranging from one week to two months.

Atar Fire expertise was instrumental. Their detailed report after witnessing the required tests proved valuable for our compliance needs.
